"Good sound, they don't last more than a few months..."1.5 starson by federicoba
Pros: Nice Sound, good battery life, good noise-cancelling.
Cons: BAD mechanical design = They break every few months and require exchanging them.
Summary: While I have no complaints about the sound quality, noise cancelling or battery life, mine have broken at the same spot twice (= poor mechanical design). The problem is at the point where the head-band meets the ear-piece support at a right angle (which means it's probably due to a poor choice of fillet radius resulting in excessive stress concentration leading to fatigue cracks). I was extremely careful with the second pair but even then they only lasted for 10 months. I would definitely NOT recomend this product (something at this price level should last more than a few months).
