In general, not a bad device, quite convenient, I listened to music for 4 hours without recharging out of the box, it works from the charging cord, sometimes there are friezes in the sound transmission, there is a software volume limit, the situation on the TV is not very pleasant, 2 pairs of headphones are connected easily and naturally, but sometimes the sound slows down, DTS does not support, while the flight is normal, if anything I will add a reviewSee full review
