Turbosound iX15

EDIT: Sound is now 5 stars, the noise we experienced was due to no XLR cable grounding the speakers, requiring a mixer making blue-tooth features a bit useless...

All my music sounds so much clearer and better, even if we are experiencing some noise on both Speakers via BT / iPad (wireless setup, didn't check cable setup yet), but it could also be me who is expecting too much, I asked an Audio Expert to double-check (I will let you know if anything change).
Turbocontrol app (iOS) will not connect eighter (even if streaming works).

I bought 4 and one of them is distorting.
I've e-mailed Thomann and I'm waiting for their response (only e-maiuled them today!).
Can't give 5 stars when only 75% of them work but they sound transparent, clear and seem to sound great with all frequencies. Looking forward to having the naughty one swapped though!
