About.com Rating 4.5 Star Rating


The Bottom Line

Sennheiser's model RS-120 wireless headphones give consumers an easy-to-use wireless alternative to open-air speakers and headphones with cords. Because they're wireless, you can listen to music or TV without being in the same room and without blasting your stereo or television speakers. The ease of installation and versatility is a huge selling point because you can use the unit for multiple devices with minimal exertion.

Guide Review - Sennheiser Wireless Headphones: Model RS-120

Having never worn wireless headphones, I wasn't sure what to expect from the RS-120. My initial concern was that the wireless signal would be weak, but I liked the overall product design. To begin, I attached the red-white stereo cables to the audio output on my television, and charged it for the recommended 24-hours.

The headphones feature an on-off switch, volume control, and tuner. To use them - put them on, turn them on, and tune to the clearest frequency. Initially, I was a little disappointed because I thought the headphones would eliminate audio coming from the television speakers, but I soon figured out you can lower the TV to an almost muted level, and still receive a good audio level on the headphones.

With the audio issue resolved, I wanted to see if the range equaled Sennheiser's claim - 100m or 300'. I wore the headphones around the house (50-100' from the transmitter) and discovered the signal weakened as I put more walls between me and the transmitter, but I never lost total signal while walking around the house. In order to get the 300' range, the signal probably requires an unobstructed path between the receiver and transmitter.

The audio quality is excellent - better than any audio coming from the television. The only drawback is the lack of a 1/8" jack for connection to other devices, but that isn't an issue for TV-video equipment. This is a great product for those watching TV in a noisy environment or who want to keep the audio level down for others.
