I think they sound great, but I'm not really qualified to speak as an audiophile. They are very clear for the stuff I listen to, and the headphones definitely block out surrounding noise.
Unfortunately, I don't wear headphones very often though... as an IT guy I have to keep my ears open for the phone and walk-in requests for support, but I LOVE the Play360! I have it hooked up to my laptop while I wait on the Lumia, and it has really nice sound. I had it going for 6 straight hours on Sunday while I was reading the forums and cleaning up around my apartment. I've used it throughout the week for some music in my office.
LMAO! That's hilarious! The sad part... it's pretty true about me. I pride myself on my system uptime at work, but I wouldn't ignore the hostages. I have a hero complex... gotta fix EVERYTHING.
