I am currently optimising the compensation for my binaural recordings towards my neutral target and was doing lots of tests and recordings to verify if the recorded sound represents the real headphones. I still need to invest a bit more time into it and set up my KH80 again to perform some additional measurements. 

Just as a demo I prepared a first sound sample of the Soundcore SpaceOne comparing it against the Q30. In the audio file can hear in the Q30 playing with my already known EQ-settings starting first, then switching over to the SpaceOne and so on. The SpaceOne is playing with its default settings, although I tried to create a quick EQ to tame the horrible sound a bit, it still doesn't really sound any decent. 

The compensation I used for this recording is derived from my HD58X EQ, thus listening to the sound sample with the HD58X and my latest EQ setting should give you a pretty realistic representation of both headphones. 

Below the Q30 with EQ in green, the SpaceOne with its default sound setting in blue: compensated for my neutral target:

You can notice that there is a strong peak close to 17khz which of course is bogus, but this is the effect of the HD58X having rather a dip in this area, thus using this as base for my compensation will make other headphones appear with a peak here. I didn't correct for this dip in my original EQ, as it shouldn't be that hearable anyhow, but I want to optimise my compensation in such a way to avoid these issues and need to back check with the speakers again to get a valid final compensation setting.

I think you have 4 q30 measurements and they all are completely different. Different compensations and microphones I believe. Jesus:))

Yes, the microphones shouldn’t matter but my current compensation should better represent “neutral” in regard to speakers. It may be not perfect but that’s what I am currently working on.

Also, Oluv, how is the noise cancelling on the earfun free pro 2? Compared to the q30. I've has the airpods max for testing period and they were really really good. The best I've heard, regarding noise cancelling and transparency. Also. There is the new anker soundcore motion 300. I don't think it's worth the time. It might be decent tho. And the preorder price is around 50$ with the coupon in the email.

The EQ you mean of with the Q30 is the same EQ in app or you've made a new EQ separate from the soundcore app?

Foltea Iustin

It's the same as usual. Inside the soundcore app.

The one from the app, although I may post my latest one as I maybe readjusted it slightly afterwards. I could also try tweaking it a bit more towards my new target.

The current custom eq on my Q30 right now was from the last eq update you've made a year ago

Noise cancelling on inears is always a bit worse than from overears. I also found the AirPods Max to be by far the best and also decent sounding. If I had money I would buy a pair and try equalising them through the hearing profiles indirectly. ANC on the AirPods Pro was considerably worse. It may also depend on how well the tips seal your ear, but I didn’t find noise cancelling to be that much better on the AirPods Pro than on the Free Pro 2, although most claim the AirPods Pro are much better, but for my purposes ANC on the Free Pro 2 is decent enough and filters lower frequencies really well.

And are you planning anything newer than the free pro 2? If you do, I'll hold on to my q30's for slightly longer. If now, I'll get them and the 10€ tier for the eq's
