I have had these a while and have used them every weekday since I've had them. I really have enjoyed them. They're pretty comfortable and I am constantly bending over to reach for things, pulling and in impossible situations and they stay put. I usually end up taking my other pair off after a couple of hours because they are strangling me or after I've readjusted them so many times. These have stayed put with the handy neck piece. The only problem I had was it says on the box 8 hour timed use and I get 6. It maybe because sometimes I lay my phone in my cart and have to walk away. I'm not sure but I did try leaving my phone in my pocket to see and I could get no more battery life than six hours. I don't mind because my ears need a break anyway. Great head phones though, no problems answering my phone, advancing my songs or anything like that. The very first thing I noticed was the sound and I can hear clear crisp music and voices. No muffling at all! I bought a cheap pair from Walmart and they were sad.
