- They sit comfortably in the ears, do not fly off. The lack of wires was very annoying when I used to cling to them and the headphones flew off. Good build quality. Waterproof.
- The sound quality is C grade - for training it will do, but no more. A small margin of volume, I listen at the maximum in training because of this battery lasts for three hours. After a couple of months, one speaker began to gurgle at maximum volume in some compositions - apparently when playing certain frequencies. The function of transmitting extraneous sounds is too quiet - I tried all three levels, all the same, only very loud sounds are heard, you will hear the sound of the horn for sure, and if someone turns to you, you may not hear it.
