These headphones claim to have a range of about 10 meters (or about 30 feet), which they do and more. The sound quality is not too bad, but there are some issues I have with them.
First, they are extremely cheaply made. I could be wrong but I don't think they'll last a year. Also, they're not very comfortable. The padding is so thin it may as well be non-existent, and the fit (compared to a wired set of about the same price) is awkward and poorly designed, although I will say they are very light. Finally, you cannot (as far as I can tell) easily switch back and forth between the headphones and your regular speakers. Each time you do so, you have to right-click the sound icon in your system tray, select Playback Devices, select the new device, and set it as the default. The two are mutually exclusive. Just a bit annoying.
Battery life seems good so far, so overall not horrible. Get what you pay for.
