So that's now my third pair of these headphones, in less than 3 years. I wear them actually almost exclusively during sports (running) and find, as often as they were masakriert in summer by welding and in autumn and winter rain, less than a year operation period for this price is reasonable, usually worked towards the end only one Earphones or the sound was not particularly. So much for first shelf. The sound is in my opinion, great, you had a total of rich sound ('m not a really well-read guy in the field, and can not really say about the highs and lows, etc), but I feel it as I said very pleasant. (Usually I hear rock music, which sounds in many headphones rather "flat"). They also fit perfectly to my ears (size one probably just above average) are my Lord never failed or so.
In summary, a great product for athletes who puts more emphasis on durability should one probably for other models to look, but as I said they fande for use actually appropriate.
