Come in three weeks, it seems, in SF. It works great! True for self made findings, that it is necessary to pay attention to the weight headphones when choosing. A Little too heavy, so on my head when bend over the move. AND when wearing a long, it feels a little pressure. But do not know, whether it's my anatomical features… And never wore such large earbuds. AND so-Super! Convenient operation and sound like. Though I and don't listen to anything and pretty in that sense, not притязателен.

Earphones top! He took his wife. It is very choosy with regards to the sound. Chasing them enough. Good bass, have noise reduction function. Solidly made hefty (due to internal battery). Charge hold long, charging about 1,5 hours for-2 to full charge. You Can listen to even on the neck, loud. But the most important thing and important-sound quality is excellent!
