Amazon.com Product Description
These wireless headphones were designed to connect with your TV or stereo system. The wireless system allows you to move around the room without that pesky cord draping behind. It is easy to connect to TV, VCR, DVD or audio systems with the supplied connecting cord and plug adaptor. This system includes both transmitter and headphones. The high power infrared transmitter incorporates multiple light-emitting diodes (LEDs) for an extended coverage range. The MDR-IF540RKs have a transmission range of twenty-four feet (ten feet when at a forty-five degree angle.) They also receive at a ninety degree transmission angle, ensuring that you have uninterrupted listening as you move around the room. The headband is self-adjusting and sports a snug-fitting wide band. The headphones require one AA battery. If you use an optional alkaline battery, you can expect an impressive one hundred hours of use. If you choose to save batteries, simply use the included rechargeable battery and the supplied transmitter/recharger. Using this recharging system, you can expect thirty hours of use. The headphones are lightweight and comfortable, delivering quality sound. Sony has installed several technical features to the headphones to ensure a quality listening experience. The thirty millimeter drive units deliver deep bass, low distortion and a wide frequency response range (12 - 24,000 Hz). Ferrite magnets give the headphones high energy at a minimal size and weight. The PET diaphragms offer low distortion and resists bending and flexing. The open-air design allows for ambient noise to enter the ear, a safe and observant feature. With the supplied UniMatch plug, it is easy to connect the transmitter to various sound sources. These plugs accommodate both the phone jack found on high fidelity components or the mini-jack found on video components. A single volume control is found on the right earpiece for simple volume adjustments. Finally, there is a automatic power switch on both the headphones and transmitter to help conserve battery and equipment life. (The unit turns back on when the transmitter detects a signal, while the headphones turn on when they sense their placement on your head.) The headphones weigh 6.3 ounce and are a modern black color. What's in the Box
Sony MDR-IF540RK headphones, high-powered transmitter/recharger, NiCad rechargeable AA battery, connecting cable, UniMatch plug adaptor, AC power adapter and user's manual.

 The hissing is loud and impossible to stop January 7, 2009
L. Ojeda (New York City, USA)
There are many reviews that state the hissing problem, but I decided to pull the trigger anyway since I was concerned about interference problems if I went with the traditional RF type headsets. These work as advertised but make a lot of loud hissing sounds that ruin quiet scenes in movies. Still a good deal ultimately by my standards since they work with any of the three infrared headsets I have from my minivan, so I don't need to purchase any additional headsets for late night movies while trying to keep the volume down. Recommeded purchase only if you can deal with the hissing problem that seems to be inherent in this particular model.
 good product December 30, 2008
bob fox (Pennsylvania USA)
Sound quality is fine. The big advantage of these headphones is that you can still hear sounds in the room, so you can hear if someone is calling you, the phone rings, or a laundry buzzer goes off.
Barely Adequate December 23, 2008
David G. Sass (Worthington, Ohio)
Easy to set up, sound quality is fair. Thin, uncomfortable foam ear cushions and cheap plastic headstrap. Simple exercise motions enough to dislodge it from your head. Recharging system tacky - tricky to make charger align with contacts. LED transmitting lights didn't work.
To reduce hiss turn up source volume, turn headset volume down.
Barely good enough for casual, stationary use for limited time. Since I bought this primarily to use while exercising, I'll search out a more comfortable, better engineered model.
 Not with plasma TV December 9, 2008
Lee A. Wheeler (Decatur Island, WA)
These definitely do not work with a plasma TV. The static was horrible and would not recommend them for this application.
A good infra-red headphone for your money November 2, 2008
J. Zapata (New Jersey, USA)
This is exactly what I was looking for. Good sound, convenience, no hiss, perfect for wathcing tv without disturbing your sleeping wife.
I'm happy with this purchase and would certainly recommend.
