Everybody's trying to get a piece of the Nintendo Wii. More and more new products are trying to become Wii-centric, framing themselves as vital accessories for Nintendo's system. Even if the product's relation to video games is tenuous at best, companies still want the Wii name on the package. Take the Turtle Beach Ear Force W3 wireless headphones. The company touts how they're "designed specifically for your active movements while playing Nintendo's new flagship console." But they'll actually work with any stereo audio source that offers standard red and white RCA jacks.
The Ear Force W3 consists of the headphones themselves and a transmitter. About the size of a VHS tape, the transmitter base station connects to the audio source--Wii or otherwise--with passthrough plugs. That means you can connect it to anything without breaking your existing connections--the source device can remain linked to your TV or AV receiver speakers. Once the transmitter is set up, just put the AAA battery into the headphones, and you're ready to go. Audio signals are sent from the transmitter to the headphones via infrared beams, so you'll want to maintain a line of sight with the transmitter--it can't be hidden away in a cabinet or set too low in your AV rack. Otherwise, the sound will turn to static and then go silent.
We were concerned that the headphones' infrared transmission might interfere with the Wii's own wireless remote and sensor bar, which also uses IR beams. Fortunately, we didn't encounter any problems, and as long as you keep the transmitter and the Wii's sensor bar a respectable distance from each other, you probably won't, either.
