Ive had them for over a year. or two. got them when they first came out. Always happy with them. Last weekend did my usual MTB ride with them but left them in my jersey back pocket. Into the wash, into the dryer. Was excited cause I thought I could upgrade to the newest version. EXCEPT, Charged them up and listening to them RIGHT NOW. Cant ask for more.
