I wanted to start this post so that UBoom X users can share their experience with this speaker. Please don’t ask me why Earfun released the speaker with a non final firmware, I had approved 039 as final one in mid September. Official release was planned for October 8th, so not sure why some already got it before.

Please all UBoom X owners leave a comment here about your experience so far and what you like or don’t as I am also curious to hear how others perceive the sound.

I’ll leave that post public so that everyone can read everyone’s comments.

I hope you like the speaker and it somehow meets your expectations , thanks for sharing your thoughts,

O.

PS: this nice image was sent to me by Joy who apparently loves the speaker 😍

When I get mine I'll come to comment. Classic EarFun screwing things up. Likely they manufactured the first batch before 0.39 was available or didn't have time to do the firmware. Beyond stupid of them to send them to people and not even instruct to do the update.

LeJJ

Got mine this evening. Easy update to 0.39 firmware. First impressions: Tested it against my Tribit Stormbox Blast. The UBoom X is has a WAY smoother sound. The Tribit sounds artificial (voices and instruments sound “digital” versus “natural” if that makes sense) and the bass, while quite abundant, is bloated and sounds disconnected and not blended well with the music. I really like all of the Oluv equalizers. The first 3 options (studio, indoor, indoor +) are perfect listening in a quiet environment…they sound awesome! Then of course the more boosted modes are well done and sound fun and dynamic.

LeJJ

I’m definitely interested in Oluv’s desktop mode because I think my inside listening could benefit from decreased midrange frequencies.

LeJJ

Oh and the speaker is very nice looking and seems high quality. Also interested to see people’s experience with TWS (stereo pairing) because I’m probably gonna buy another!

Rodolfo Huerta

Hello Oluv, everything is good with your work, although the sound needs to be improved further, I will continue supporting you, keep up the good work but I will tell you one thing, ok, I subscribed and I have not yet received any discount code to buy the speaker. I don't know how I'm going to do it because I would like to buy the speaker.

Initial impression. Both of my UboomXs came with firmware 0.33. Updated both to 0.39 easily with the app. I paired both in party mode (mono) accidentally at first. The speakers seemed to drift in and out of sync causing strange reverb effects and echos. I unpaired them and paired again in TWS (stereo) mode and the sound was much better. I used channel identification sounds to confirm I was properly paired in stereo mode. The signal between both speakers dropped a few times during initial testing but I was in a very radio congested backyard area with numerous residential routers nearby and Wi-Fi cameras. I will try the speakers in a more open space such as a park sometime soon. So far the Oluv signature Outdoor mode seems the best for TWS outside because of the minimal stereo enhancement. This is my main use case for these speakers. I would ask if Oluv can possibly develop a signature sound tuning specifically for TWS mode with no stereo enhancement but retaining the bass and treble boost of outdoor mode. This is probably asking too much as Oluv has done so much work already. Overall I am really enjoying my pair of UboomXs and can now retire my old Partybox 100 (Gifting to a friend).

I would have liked to include a desktop mode and after hearing them in TWS maybe also an own more balanced TWS mode but Earfun is not interested, they claim it’s not possible blah blah

hi oluv, I also posted in Reddit, here is my opinion: Just finished recording them playing against each other, have to go back home and edit the video, this time I use my own diy binaural microphone and I hope it work, or otherwise I could only give you guys conclusion in word but audio. The UboomX is so so so much louder than the blast in outdoor/Boom xXX mode, like the sweet spot of UboomX maximum volume is like 10-15 meters, meanwhile the blast is 3-5 meters and which is crazy. It make wonder if my blast is defective and I check a lot of options, I don't find any problem myself, If my blast is actually not defective then UboomX is clear winner. Like I said, when you use UboomX outdoor eq, you need to stand 15 meters away, and you still hear bass from the song, the vocal is there, but here I have to mention something bad of the UboomX: 1. You would actually notice some harshness/distortion in maximum volume of Outdoor/Outdoor+/Boom xXX mode, you can lower one notch to fix the problem, it is still louder than blast, but the volume difference of the last step and the second last step is quite bad, that I felt like Oluv could even make one or two more steps in between them, and since I can barely hear anything in the last few low volume steps of UboomX, I think maybe Oluv use those steps for high volume. 2. The sweet spot of UboomX outdoor modes is like 10-15 meters for me, but the third last volume steps is actually quieter than the blast, so for close range listening you have to change to indoor settings, and with indoor settings I would perfer the UoomX. 3.once again, the blast seems more control for me at maximum volume(but it is a lot quieter), in some songs the UboomX suffering from harshness and compression issue, some songs even the secound loud volume step has those problem, and if I switch to the third loudest volume it then becomes quieter than the blast, I really have to switch back to indoor setting(then it beat blast again), not sure oluv intended this way, but I felt like maybe he can even make all the outdoor mode better with better volume step management. 5.The UboomX is lighter 1kg, which is huge meaning when you decide to take it outdoor, not to mentioned you can charge it with a power bank, or use it as a power bank for your phone, and also the strap of UboomX is very useful for me. I maybe could have written more opinions, but right now I am just sitting on the ground outdoor typing these, maybe I would later on add more options, so far the UboomX beat blast no matter indoor and outdoor, like I don't know, if you test UboomX maximum volume at 5 meters, it would sound like shit, It also happened on me, I am like "hey yo so fucking harsh and loud what's wrong" then I walk few steps backwards I am like "Now this is way better, and why is my blast this mucher softer????" feel free to comment, gotta head back home.

LeJJ

Oluv, which of your signature equalizers are supported in TWS? Specifically, I’m I’ve been enjoying studio mode a lot and I think it would sound even more hifi in stereo.

oluvsgadgets

Studio and all outdoor modes should work, but I didn’t have that many problems with indoor and indoor+

LeJJ

2 days later… I LOVE The studio mode. For me this is what makes the speaker very unique and enjoyable. At first the studio mode sounds anemic, especially when cycling through other bass heavy settings. But after a few days, I think the sound really opened up and studio sounds the best to me by far…Balanced, full sound. Boundary enhancing the bass by placing it a corner or near a wall (which is most of the time) adds a fun boost to the lower end. Definitely going to buy another, I can see 2 of these in studio sounding like a portable full range sound system. Very impressed! I’m not aware of any other portable speaker that sounds this natural. I also find the volume steps quite useful, as I’m mostly listening indoors at low to moderate volumes.

Just got my second uboom x! I will use them for a few weeks then post my experience here ….and then probably write an Amazon review as well.

Marcus Rother

I just did the process for the code again. then the site said that I already did that. But immidiately after it, the code came to my email.

Raelin Trenta

Hey Oluv, after listening for a day, here's my first impressions of the UBoom X: After unpacking, turned on and connected to my phone, mine came with 0.33. Seamlessly updated the firmware to 0.39 before playing any music. Now, maybe because this is my first boombox-sized speaker I bought, but the first track I played using Studio EQ was an AJURIKA track. When the track started, I immediately noticed the deep bass. Like, that 40-50hz bass really coming down. It was an amazing experience I've never had before on a bluetooth speaker. Coming from a UBoom L user, initially the X sounded flatter to me, but as I listened more and more, the X just sounded more natural to my ears. Like you mentioned on your previous comparison videos, the UBoom L has a slight mid-bass boost to compensate for the passive driver tuning, which I definitely noticed even when compared to Indoor mode on my listening. The treble, although flatter on the X it is more well-rounded and "detailed" than the compensated treble tuning on the UBoom L, which is fatiguing at times when I place it beside my bed, and especially when played on Outdoor mode. As I'm mostly listening indoors, my favorite modes are definitely Studio and Indoor. In my tiny living room, Indoor+ gets a bit droning for me. Of course, the outdoor modes are fun and dynamic, which sometimes causes my room to rumble at times lol. I even did a bathroom test and am surprised to not experience any sort of bass droning on Indoor mode, compared to the UBoom L which boosted the 70hz more on a bathroom setting even on its Indoor mode. I played a quick test on the outdoor modes, at around 80-90% volume its playing quite clean. However, the jump from 90-100% volume to me was a bit too wide that I sometimes couldn't anticipate the surge of volume. Perhaps we could have a bit more control on those volume ranges. I'll do more listening outdoors, gauge how much distortion can be heard, and further share my thoughts on a reply. The lower volume steps worked fine though in my use case. I also tried using AUX input and I'd say it has a little bit of latency, maybe around 10-15ms. Still quite good though, I might be able to use it for gaming. For some reason though TWS pairing with a UBoom L didn't work, perhaps I didn't do it correctly. As for firmware thoughts, I'll be looking forward to your existing firmware that keeps the studio mode, and keeps the stereo enhancement on the Outdoor modes. Studio is definitely my favorite and would want to keep it for my unit. Once again, congrats and thanks for your great work, Oluv. I'll definitely be keeping (or purchasing another one of) the UBoom X in the future. Cheers!

oluvsgadgets

Thanks for sharing. BTW, There are half steps on the speaker. So if you turn volume up 1 step from your phone, you still have 1 step in between if controlled through the speaker.

Raelin Trenta

Thanks. I'll definitely fiddle with it, but I would probably just use the speaker controls at that point. I got thick thumbs to try and attempt to half-step the volume slider on my phone, its also possible on Android. Considering that I'll be using the speaker mostly indoors, I think I'll worry about high volumes when the time comes lol

Raelin Trenta

Update, I managed to get the UBoom L and Uboom X in TWS. What I did on my case is that I paired to UBoom L first, turned on the X then set to pairing mode. Then I held the Party mode buttons for 2 secs to enter TWS mode. What's weird is that the L kinda turns off a bit (power light comes off) but stays connected. Then you can start playing music, UBoom L is left channel and X for right. Going to try and experiment if I could get the X do left channel next.

oluvsgadgets

Yeah it’s weird. Sometimes it works sometimes not. It’s best to not play any music during pairing and start pairing immediately after powering both on. It also helps to reset Bluetooth for the UBoom L before (I think keeping + and - pressed for some seconds)

Raelin Trenta

Updated review on the outdoor modes: I'm liking Outdoor mode so far, a good balance between big bass and treble, and neutral tuning. Outdoor+ for me makes the speaker struggle a bit with compression at max volume. Boom xxX doing its own thing, boomy as hell, while Ground O has the most treble that it's piercing sometimes when listened directly. But hey, it works when the speaker is facing upwards, on the ground, and has this BB3-like bass to it. Did a karaoke session while cycling through the outdoor modes, and I'm cycling through Indoor+, Outdoor and Outdoor+ as my go-to modes for karaoke setup. And yes, AUX latency is almost unnoticeable. As for distortion, I think an average joe can manage the amount of distortion on the outdoor modes. As for me, I don't mind the distortion so much, but I'll lower the volume 1 notch just to allow the speaker to play clean. It's already plenty loud at that point for me.

Jan Christmeier

First impressions, especially for TWS mode: One major plus compared to the Uboom L is that this speaker has a dedicated button for pairing, which is great. However, it’s important to note that the light should be blue, not white. Blue indicates TWS mode, while white signals Party mode. Simply press the button on both speakers simultaneously for two seconds, and they should connect. When both speakers are powered on, they do automatically connect in TWS mode. However, it takes noticeably longer than with the Uboom L—almost twice as long—so much so that I initially thought it wasn’t going to work. As for the speaker itself, I still don’t really like the design, but in person, it doesn’t look as bad as it does in pictures or videos. The build quality is also decent, especially for the price. The Most Important Part: Sound Quality (Firmware 0.39) Using TWS makes a huge difference indoors compared to just one speaker. This was the case with the Uboom L, and it’s the same with the Uboom X. That’s not really surprising. In Indoor+ mode, the sound is incredibly powerful and even rivals the fun factor of my 25-kilo subwoofer. But, honestly, it’s a bit too much—especially in TWS mode. When using just one speaker, the Indoor+ mode makes more sense. In my opinion, the Studio or regular Indoor mode is best suited for TWS. I haven’t experienced any dropouts in either of the Indoor modes so far. I can’t give a final verdict on the sound yet. Over the past few months, I’ve spent a lot of time fine-tuning my headphones with an EQ to achieve a sound I really enjoy and can use for everything. The Uboom X is still far from that level. I feel like there’s a sort of "veil" over the sound that blends the frequencies together. This is most noticeable in the mid-range, which is why genres like rock music, soundtracks, or live performances (where a lot is happening and instrument separation is crucial) don’t sound as good as they could. But honestly, no boombox or Bluetooth speaker I’ve ever owned has truly nailed this. It’s one of the hardest things for speakers to master, so this is really a critique on a high level. This issue isn’t limited to TWS mode either—it persists with just one speaker. For my taste, the frequency range between 200-500Hz could be toned down a little. I think that would help reduce this “veil” effect. However, this might just be due to my personal preference from using EQ-tuned headphones or the fact that my small room isn’t optimized for acoustics at all. One thing I’ve come to really appreciate on both the Uboom X and Uboom L is the fine volume adjustments at low levels. For example, the Tribit Stormbox Blast is way too loud even at its lowest setting, making it hard to enjoy in a relaxed setting. Overall, my first impression is very positive. Maybe I expected too much in terms of clarity and instrument separation, but I don’t think we’ll ever get a Bluetooth speaker that can achieve the level of detail you get from good headphones. I’m still undecided about keeping both speakers, as one is more than enough for my needs. Plus, with two Uboom L and two Uboom X, I might have a bit too much fun for my ears aka Earfun 😄 PS: The default Earfun tuning is honestly terrible.

Peter Neurath

I am very impressed with the sound Especially the indoor modes. Oluv has really delivered here. Thank you Oluv! Now I‘m wondering, at low volumes, in the respective mode, what advantage does the custom firmware of Oluv 0.39 have compared to the EarFun app version 0.39, e.g. in terms of the dynamic EQ? Liebe Grüße aus Hamburg 😉

oluvsgadgets

The biggest difference is the added desktop mode which in my opinion makes more sense than studio as indoor sounds very similar as studio just with added stereo enhancing and some dynamic EQ. The other difference is that also all outdoor modes have dynamic EQ for low levels although they are already so bass boosted I didn’t want to exaggerate and just added a bit

oluvsgadgets

May I ask what you used as reference for your headphone tuning? Headphones even if referenced towards neutral studio monitors will always sound more detailed as you lose the entire diffuse room reflections which usually mush the sound a lot. But the indoor mode shouldn’t sound that different to a neutral monitor.

Joe

I'm not sure if I have a bad unit or not, but it distorts really badly with certain songs. I mostly listen to electronic / trap music. For instance if another U BOOM X user could try playing the song "Vanic X K. Flay - Can't Sleep" on any EQ setting, even Studio, at loud volumes does the deep bass drop just utterly distort?? I like the speaker but it's almost not usable for me right now. For years I used the Stormbox Blast in the shower, never had issues with this.

Jan Christmeier

Don’t take my approach too seriously. I don’t have studio monitors, and my method is more like: "It should sound good and not have any annoying spots." About a year ago, I bought the Truthear Zero Red, and later the Truthear Hexa. They were the first headphones I’ve ever had that I could use without EQ. They don’t sound perfect, but more than good enough. Even with your free pro 2, there were always some hurting peaks. I used your "mainstream tuning", also because this Region arround 300-400hz was to much for me. So it could just be habit. Currently, I’m using the Moondrop Para and a Topping D50III + A50III stack. The D50 has an integrated PEQ, and I used that to "tune" the Para. The starting point was actually the Crinacle target. Unfortunately, I can’t upload images, so I can't include a comparison of the graphs here.

oluvsgadgets

Hmm, plays completely clean with mine even with Outdoor+ which is most prone to distortion because it has the lower bass most boosted. There is some slight harshness with outdoor+ at maximum volume but it plays pretty clean with my unit. I once got a message from someone where the passive radiators were not glued properly. Which minute exactly is affected? Maybe I have missed the right part

Joe

Thanks for checking that, my unit must be faulty. It does it pretty much on the first deeper bass note at 17-18 seconds in and then every single other time it hits that note. Even on Studio EQ. I will have to see about getting a replacement. Other than that I am loving the sound and custom EQ's.

Sn

No distortion here at second 17-18, even with Outdoor+

Sn

Just updated my speaker and haven't tested it much yet. But I can already show a good example of the serious difference between all Oluv settings and the Earfun default: In the song “Never Be Like You” by Flume, cymbals are used in between. In the Earfun default, it is actually completely unclear what this sound is, while in Oluv's settings a clear cymbal can be heard. It's just a detailed observation, but I think it's emblematic of the difference between mainstream settings and a more sophisticated approach. On the other hand, I'm currently playing “Nobody's Soldier” by Hozier and it sounds very flat in “indoor” mode. Not nice at Earfun standard either, though. I'll keep listening to it.

Sn

Seriously, I had to laugh when I switched from Indoor+ to Default.

Rick

Joe

Thanks so much. There is apparently hardware issues / variance. Sad when so much work was put into this project from Oluv.

oluvsgadgets

Which track did you try? I didn’t try every single genre but there maybe extremely mastered tracks that can in fact cause issues.

Rick

I told you once- all cane, I need a painkiller-armand van Helden. I listen mostly hardcore, but I noticed it with these song. The passive radiator goes down inward if you know what I mean. You hear a clipping sound and then the woofer moves weirdly. I don't see it at 70 procent or lower. But I do think it is my unit

Rick

Hey man, I have the same thing. With hardstyle and so on I notice weird rumbling in the passive radiators. It sounds broken. I contacted earfun but no anwser yet

oluvsgadgets

I need a playlist with tracks that I can try. I tried “I need a painkiller” but there are different versions

Joe

Roddy Ricch - The Box (it has a ton of cursing btw, NSFW) It does the same thing. Bottoms out, it's a rough beat but the Tribit Blast plays it pretty clean.

Julian Seidler

Where do we get your custom firmware?

Lennards Welt

Ich habe den Uboom X seit vorgestern, konnte ihn aber noch nicht ausgiebig testen. Was mir aufgefallen ist bei Liedern, bei denen es einige Sekunden Stille gibt. Dass der Earfun ein leises Hintergrundrauschen abbildet. Wenn ein Lied recht leise abgespielt wird höre ich bei 30 cm Abstand zum Speaker leichtes Rauschen. Ist das nur bei mir der Fall, oder bin ich nur sehr empfindlich? Bei 'Liberty' von Anette Askvik hört man das Raschen deutlich auch weiter weg.

Received mine today. Updated to 0.39. First impressions are really good, as expected. I don't have many Bluetooth speakers so I can't speak critically sound-wise, but let's just say this plays the smoothest and the most detailed. It's no comparison. I mainly listen to house music, so I like some bass boost, indoor+ is perfect for me. Also, the volume steps are great as I don't expect to listen to very high volumes all the time. Doesn't lose bass quality significantly on lower volumes thanks to the dynamic EQ. Speaking hardware wise, it does have have some slight hiss on low volumes. But I am nitpicking here, I expected this from a Bluetooth speaker. The good news is that the hiss is just so so. It does not overpower the music itself. Heard much worse. I tried some of the tracks the other members mentioned here but my passive radiators seem perfectly fine. No bottoming out or distortion. So it's hardware variation, unfortunately. Thank you, Oluv! I'll try to update this if I notice any negatives, which I doubt I will ;)

oluvsgadgets

Bei dem Lied ist es extrem, bei etwas volleren Arrangements, fällt das gar nicht so auf. Ist digitales aliasing, müsste schauen ob ich das mit anderen gain werten zumindest für die indoor Modi etwas reduzieren könnte.

Joe

Rick I used Earfun's site to post for a replacement, they haven't responded. If you ordered it through Amazon you can go into the options on Amazons site and go through that for replacement. I've already gotten an auto-email so hopefully they get back with me soon.

Chesco

I like it a lot. I have one gripe with it though. To get the most out of it I listen from tidal through aux (via my wiim mini) . Like this the bass and the treble are just way too much even on indoor. I guess this is because it was tuned on Bluetooth via ios and (presumably) Spotify. The Spotify and Bluetooth compression algorithms probably just take more from the bass and treble is my guess. When I lower bass and treble from my wiim app indoor sounds incredible though with lossless. I think something that deals with this would be fantastic. I guess seperate tunings are not going to happen. But already having the 10 band in app eq work on top of your tunings would be a great improvement I think. But for now, using the wiim 10 band eq also works well.

Lukáš Bartošek

Hi Oluv, thoughtfull comrades, I really enjoy the capability of the speaker. Having all those sound profiles and EQ for extreme cases is blessing. When indoors somehow the original Studio mode is the best (didnt try the Desktop mode firmware yet), but would be nice to have it with little bit more bass. Indoor and other modes seem a bit treble heavy for indoor use. Especially male voices are a bit drown as a result. My only gripe I have is with low level listening (also where graphic EQ comes really handy), where 2 or 3 lowest volume steps are really noisy. This is only perceivable while listening nearfield (half a meter) and with music with empty places (vocals with one or two instruments). The noise comes with singnal, so no music barely no noise. But regardles of sound profile the stronger the signal, the greater the noise is. Other than that, its really great. Thank you Oluv.

Ralf Friedmann

Today i played some music on the Uboom X next to the football ground , as entertainment before a match of my son.. the other parents were pretty impressed by the sound, and the trainer immediately ordered two items!! 😂 I used „outdoor plus!“ 😉

I will tell my story. I bought this speaker after watching a lot of comparisons and listening to a sound recording. I tried to set up a better sound, but with custom eq it can not be done, because all the time I get in the end a strange voice and high frequencies. And I know the speaker is a good speaker, it has bad power and quality drivers, it's capable of more than what I'm hearing. I don't understand why no one really talks about the sound problem at low volume? It's not like it's impossible to listen to it at up to 50%+ volume. I had the latest firmware 0.41, and on it it plays like a fucking radio at low volume on eq from Oluv, the sound is disgusting. I saw that people say that 0.39 is the most successful firmware. I wrote to support, I got the firmware, I reflashed to the official version 0.39, the same shit, at low volume the speaker does not play.... In the end, only after reflashing to custom firmware from Oluv, where works dynamic eq in all its modes, the speaker began to play normally and at low volume too. Bonus is Desktop mode (Studio mode in the app) where the sound gets purity and quality, I find it just a particularly good mode for low volume listening. I don't understand why no one talks about this problem? Does everyone listen to the speaker at 60 to 90% volume? That's the volume at which it just starts to sound right to me (for example on the Outdoor+). Before that it has a nasty sound, especially at 15-30% volume. Why would Earfun ruin something that was working well....

Naked Force

Cancellation... DominikReviews from YouTube suggested to me that it's a dsp problem. And indeed, from the iPhone the speaker sounds different, clearer, richer and crisper highs and voice, as well as a bit more bass. That's even considering that my android phone has Dolby Atmos, which improves the sound and volume a bit, but still the sound when connected with the iPhone is much better. And why didn't I check this раньше🤦🏼‍♂️? But i think in any case dynamic eq does its job well. Plus, I now have a cool Dekstop mode😎
