The home theater-focused wireless headphones category is, compared with the larger realm of Bluetooth headphones, a niche market. Sennheiser continues to fill it with quality offerings, however. Introduced at CES, the $279.95 Sennheiser RS 175 is a powerful set of wireless headphones, with a dedicated recharging stand and transmitter that accepts both analog and digital inputs from your home theater components. It's strictly for home use, using its own modulating transmitter instead of Bluetooth or another mobile-friendly standard. The sound signature is very sculpted, with bright highs and rich lows, as well as the ability to add more bass. There's also a Surround effect mode for movies and television. Purists seeking flat-response audio should steer clear, but if you love rumbling bass with your movies and music, the RS 175 is a solid wireless—but not portable—option to consider. If you want quality wireless audio on the go, the Harman Kardon BT is an excellent Bluetooth choice...
