Well, given that I have been expected from those earphones virtually nothing, ma very surprised. The sound quality is relative to the wireless transmission excellent. Headphones are comfortable and well fit on the head (unless you have long hair, then fall down) and sufficient attenuate ambient noise. Volume is high, which has a decidedly pleased. The range is fine, but unless you have thick walls, do not rely too great impact. The only thing I would vytkol a microphone, if you call with your friends while playing, rend them sound from headphones. It can be solved by reducing the microphone volume, while reducing ambient sound, but this is not it. Whereas the built-in microphone, and I would expect that, thus, nothing terrible. Also, battery life earphones nothing is too much, a vybíjajú even when they are turned off so that nabíjam quite often.
the volume and sound quality price sufficiently attenuate ambient noise comfort NETL microphone sound from headphones vybíjajú is even when they are turned off

Headphones are pleasant to the ears. Pressuring, even after a 4-listening, I had no way sweaty ears (tested in the summer 25c). The sound is okay, I would compare to Koss Plug. Slightly stronger bass. On his head sits quite well. The distance is really up to 10m. Manage max. One wall. Ie. usable for wireless listening with pc. Endurance 8h is true, headphones However, even when off discharges slightly (2 days to discharge completely). Personally, I found charging via USB cable to - I'm so engrossed Actually one USB receiver and second rechargeable cable

Regarding the sound and the next, and I meet headphones. They are lightweight and well kept. The downside is very short power cord (about 50 cm), with connector Nokia, so the only option is to buy a USB extension cable. What bothers me, however, not constant buzzing. When playback is slight or not to hear, but if anything wrong, so it's very annoying.

headphones are wireless, which makes me limited in movement and touch to make a call or listening to music in another room.
