Overall, I'm very happy with the sound quality! Its pros: A good sound in range breaks through two walls, a mediocre microphone can be conveniently unfastened and can be squeezed out. On the very first day, the whistle of the transmitter was accidentally bent by 35 degrees))) everything works, I did not correct it back. If it were not for the nuances with the software and the pressure of the darling, it would have been 5 stars! Got cons: 1) Hyper's proprietary program for setting up and tracking% of the battery every half hour gives a sound in the headphones bzzzzz, if the program is turned OFF, this problem disappears. (software bug) I thought that marriage - I read it on foreign forums and it turned out. In general, the program is not needed and does not affect the use in any way - It turns out that I turn on the program just to check the percentage of the charge. 2) quite strongly presses the ambroshurs to the ears, as on all headphones, we unclench the springs of the darling. 3) leather covers for the ears, after 3-4 hours the ears are sweaty, here you can just take the fabric upholstery on the alik, they are removable.
