On par with most wired headsets in the $100-$150 price range 01/20/2013
These sound great. I was skeptical at first because bluetooth headsets are normally not on par with traditional wired headsets. After using these for a week and comparing it to other wired headsets all I can say is wow. It's balanced, crystal clear and powerful. They're very loud (if you have the right music player especially when on a mobile device). Highs and mids are clear, bass never over powers anything else and still remains powerful. There is also no muddyness at all. I can't really comment on battery life since the longest I've ever used them for was about two and a half hours. They are rated at 8 hours I think. They are also very light, though not light enough for you to forget that they are there, which is a good thing. They also feel sturdy enough
range is not that long, i would say around a little over 8 feet which is close to the 10 meters that it is rated at.
The headphones don't come with their own charging brick/puck. They only come with a usb to its own proprietary charger. I guess if you have a spare charging brick that supports mini or micro usb cables lying around you should be fine.
Very hard to find information about it such as specs.
Remember that these headsets aren't water resistant, so sweat may damage them. (Not much info out there for these so i hope im helping a bit)
