My two cents.
I bought them the last time as I needed to replace the first pair I originally purchased.
Sooooo, Purchase 1 (P1) had a speaker go out after about 3 months of use (I bought those on 4/20). Do note that I sweat like a pig on the way to a luau and can possibly attribute the speaker dying to that. Additionally, the play time on that set was only around 4-5 hours.
I picked up Purchase 2 (P2) on 7/6 and so far these suckers have been great; nearly 8 hours of playtime!
I will say that on both sets the buttons have always been difficult to de-press and send a signal. However, I easily over look this as..well...I'm working out and just need something blaring in my ears so my musical "workout set" is good enough and I don't need to skip or go back a lot.
