My son plays video games, and he's a spaz. I've spent twice the price of these on regular el-cheapo wired headphones that inevitably get destroyed when he leaps out of his chair and dashes from the room, still wearing the headphones which are still connected to the computer.These fail to address either issue, on account of them being totally useless for video gaming and being terribly, terribly fragile.Sound QualityWhether connected directly to the computer with a BlueTooth adapter (an extra $40 if you're not using a modern laptop) or using the included "dongle" that plugs into a standard headphone jack, there is a glaringly obvious lag of about 1/2 to 3/4 of a second, which doesn't sound like much until you consider that the minimum acceptable lag for real-time audio systems (cell phones and such) is held to be about 40ms, or about 1/25th of a second. Listening to music is fine, as long as you're sitting still: the audio quality is superb, but an odd doppler-like effect is evident if you move around quickly in relation to the transmitter, especially at the extreme edge of the transmitter range. The delay makes watching a movie all but impossible for native-language films, and can even be annoying if you're watching a subtitled foreign-language film. Even if you don't know what they're saying, it's still maddening to have the actors' voices out of sync with the their lips. :-(Mechanical QualityThese are very lightweight, and as such, can be expected to be little delicate. This is certainly the case here, but on top of the fact that various parts of the headband began to crack, and eventually failed altogether (I might post a photo of mine, complete with duct tape holding the headband together), the internal wiring uses a type of very thin wire that is particularly unsuited to this application. Specifically, the wire connecting the charging jack to the main circuit board passes through one of the rotation points where the earpiece is attached to the headband, and thus comes in for a great deal of flexing. This wire snapped within the first week of use, making it impossible to recharge the battery. Luckily, my brother is an electrical engineer, and after he and I completely disassembled the unit into about thirty pieces, replaced all the wire with something a little more flexible and reassembled it, it's been relatively smooth sailing.I may be an OCD Freak, but I don't want to look like oneThe worst thing about these headphones has nothing to do with their operational or mechanical quality: it's the stupid blue light on both the headphones themselves and the "dongle". When you turn these things on, a large translucent circle of plastic around the edge of the right earpiece flashes red in some inscrutable pattern that's allegedly intended to convey the state of the battery charge. Once the unit is connected to something (the "dongle", a mobile phone or a computer) the light flashes about once a second, and the color changes to a retina-searing blue that's obvious even in broad daylight. I've never worn these in public on account of this. Try to wear them in a dimly lit room and, to borrow a little comedy from Steven Wright, your neighbors will call the cops, thinking there's lightning in your house.
