While many wireless headphones suffer from poor reception, the RS 130s have the problem licked with intelligent auto tuning and a self-learning automatic signal level control that provides maximum signal reception and a range of up to 150 meters. The headphones are lightweight, too, making them very comfortable to wear. The included transmitter and stand makes recharging the headphone batteries easy; simply hang the headphones on the charging cradle and you're good to go. With an operating time of approximately 22 hours, though, plan on spending most of your time enjoying rich sound and maximum mobility.

Product Description
Wireless headphones are popular among home-theater devotees who like to indulge in uninhibited late night movies, as well as music lovers who don't want to be tied down to their receivers or computers. Sennheiser is one of Germany's leading headphone manufacturers and a major proponent of wireless technology, so we couldn't wait to try its new-for-2005 model, the RS130.
The Sennheiser RS130s are very light, just 9.8 ounces, and we found them extremely comfortable over a long evening of watching DVDs. This set of Open-Air headphones comes with a stylish base station/charger that houses a 900MHz wireless transmitter. The newly revised system is fitted with Sennheiser's Intelligent Auto Tuning system, which automatically selects the best of three available base-to-headset channels to ensure the lowest-possible distortion and noise. To charge the headphones' two AAA nickel-metal-hydride batteries, just place the RS130s on the cradle of the transmitter base. Fully charged, the headphones will play for as long as 22 hours with built-in volume control. The base/charger can be mounted on the wall or placed near your components. All of the adapters and necessary cables are included for stereo output.
The RS130 also features Sennheiser's SRS Headphone virtual-surround-sound system. SRS is compatible with two-channel audio sources such as CDs and DVDs. SRS opened up the sound a bit so that it was less stuck inside the listener's head, but it also made the sound more echo and reverberant. Some people will like the effect, others won't. We didn't and opted to switch it off.
