4 UBoom X playing in party mode (Patreon)

It's the first time I have tried connecting 4 Uboom X at once and the result is pretty stunning, unfortunately I have no Partybox anymore for comparison, but next time we could try all 5 (as I have 5 units in total), against a Rockster Air! What do you think? At first there were some interruptions, but after some time when i started recording they seem to have synced to each other. Maybe with the TWS firmware the performance can be even improved slightly.

You will need to increase volume slightly as I had to record with a lower gain than usual to be able to capture the high levels.
