WIRELESS HEADPHONES DO MORE THAN KEEP THE PEACE

A: A good set of wireless headphones is your best option. The most common type consists of a small infrared transmitter and a pair of amplified headphones. You simply connect the transmitter to your TV's headphone or audio output jack and you're in business. The transmitter floods the room with invisible infrared light, so you won't have to worry about which way your head is pointed.

Wireless headphones have many practical uses in addition to private TV viewing. You can connect them to a VCR, CD player, tuner or cassette deck - they'll work with anything that has an audio output. And, since the sound is comparable to conventional headphones, you won't need to own both. Audiophiles take note: One company now offers an all-digital wireless headphone system. But if you have to ask the price ...

In order to extend the headset's range to a second room, several manufacturers offer optional remote-room repeaters. For even more flexibility, check out one of the recently introduced radio frequency (RF) headphones that operate at 900 megahertz. Although somewhat more expensive than infrared, an RF transmitter provides total freedom of movement as you listen to your favorite television or music program.

With a range of up to 150 feet, RF headphones effectively extend your primary audio system to each room in your home without the expense of a full-fledged whole-house music system. You can even wear an RF headset while working in the yard, doing chores, exercising or cooking.

One feature you may want to look for is a headset-mounted volume control, standard fare on RF models. If you have an older pre-stereo television, you can save money by opting for a monaural headset, but don't expect to use it with your stereo gear. Otherwise, stick with headphones that have a stereo/monaural switch. Some models can even isolate a TV's ``second audio program'' (SAP is sometimes used to broadcast second-language translations).

Weight is another important consideration. One featherweight model resembles a doctor's stethoscope, weighing in at just under 1.5 ounces. The lightest design combines a Walkman-style headset with a small clip-on receiver unit. Models with full earcups, although somewhat heavier, offer greater dynamic range and do a better job of eliminating ambient noise.

Finally, battery life varies considerably. Headphones that require lots of power typically rely on rechargeable batteries, thus reducing operating costs. One company's transmitter doubles as a headset charging and storage stand. Another model can charge a spare battery while the other is in use.

Wireless headphones have some unexpected uses. They can be a great aid for someone with a hearing impairment at home and in public. A growing number of theaters and performing arts centers provide wireless headsets to their patrons upon request. Furthermore, many conference centers use them for their interpreters during international gatherings.
