Sennheiser RS 220: wireless headphones for the discerning audiophile
Sometimes, you need to use headphones, and using headphones, especially in the house, can be an enormous pain in the ass. So you use wireless headphones, except they sound a bit like you’re listening to a crappy FM station (which is pretty much because that’s exactly what you’re doing). The only reasonable response is to drop a fortune on something from the Germans, and Sennheiser has the wireless headphones just for you.
Yeah, apparently the base of these things glows. But to be fair, they’re a pretty amazing design. The reason most wireless headphones suck is they’re sending signals via radio; the transmitter is basically an extremely low-power radio station, and the headphones just receive that signal, plus any other electromagnetic garbage floating around your neighborhood. Sennheiser, on the other hand, uses a technology they call DSSS, Direct Sequence Spread Spectrum. We could bore you with the technical stuff, but basically it chooses a thin range of radio spectrum and broadcasts across all of it.
As you might have guessed, though, quality like this isn’t cheap: it’ll be $600 street price. Also, don’t expect to hook these up to your iPod and go; the transmitter is decidedly not that portable and needs to be plugged in. Still, if you listen to music in the house a lot, and don’t want to torment anybody with your love of the ’80s, this could be worth every penny.
