Companions flawless the runner, they meet all my requirements:
1 / Lightweight> is absolutely not smell
2 / Good resistance in the ear> with their mouthpiece in silicone system, these headphones do not move when we short
3 / Its really correct. Much better than most running headphones I've tested
4 / Autonomy more than sufficient. My tests have given me less than the announced 7am but still more than 4 hours. Which is sufficient even for a marathon!
5 / quick and easy recharge. Micro-USB tip like the majority of mobile phones (except iPhone)> a single cable for any load.
6 / unbeatable price. Fewer 20th ave offered the harbor!
In short: a great product that I recommend to all the runners but also to all those who work on the move
