I've only had this for 15 months and now they are practically unusable.
Pros: - Good sound quality - Comfortable - Wireless is good
Cons: - Battery life is not even 10 hours (I do use them all day everyday so take that as you will) - Mic quality is SO BAD it's almost funny - Static noise after a year of use
Now to give context, I take VERY good care of my belongings. I have never once bumped, dropped or damaged by pair of headphones. But one day (today), they start making a hissing sound. And I can't get rid of it and after reading product reviews, this seems to be a common problem. The mute/unmute sound also goes off randomly. I don't know what has happened but it doesn't seem like it is fixable.
For the first year of having this thing, I LOVED it! The sound quality was great, the range was actually really good but now I can no longer use them. It's really sad to see this happen out of nowhere.
