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.

When I first took them out of the box, I got really, really worried as there was a ton of fuzzy hiss while watching a movie from my iMac. Ive now finally tweaked it to the right setting. For me and my computer it is setting 3-4 on the headphones, full computer sound volumes. I only hear a little static when there is a quiet point in a movie or if there is a scene change. And that is expected.
The sound quality is even better on my tv.
It is a little annoying that you have to be in view of the receptor, but all I do is just throw it on top of my tv (small tv) and lay down with it and I have no issues.
I also love the fact that the band acts as the on/off switch, as well as lack of any sound transmission, thus meaning if you fall asleep you wont be wasting battery. I haven't used the vibration switch yet, but that is another cool feature for these guys.
These headphones have saved my sanity with having to deal with loud neighbors.
Extremely comfortable, great sound,
