Product Description
From the Manufacturer
The Acoustic Research AW721 wireless stereo headphones feature the company's patented 900 MHz wireless technology, which transmits signals through walls, floors, and ceilings at distances of up to 300 feet. The transmitter sits inside or outside the house, and no line of sight is required between the headphones and the transmitter, giving wearers the freedom to move around. The transmitter comes with RCA-type line-level audio inputs with universal adapters, letting listeners connect to TVs, DVD players, AV receivers, mini systems, VCRs, PVRs, MP3 players, portable CD and DVD players, and computers. Additional features include 32 mm driver elements for quality sound, an RF noise reduction system that helps reduce interference, a self-adjusting headband, and a cushioned ear cup design that ensures privacy and a comfortable fit. The transmitter doubles as a charging base, and also includes a channel select switch so users can operate more than one 900 MHz product within the same area. The headphones come with rechargeable Ni-MH batteries.

Customer Reviews
Pros: Good overall sound quality and volume. Light weight. Use AAA-format batteries (comes with rechargable li-ion). Easy to place on charging stand. Easy tuning to transmitter. Reasonably priced. On-off switch on headphones. Surprisingly comfortable for long periods. Pretty good line-of-sight range. Transmitter power control. Around-the-ear foam cups block most external sounds from user (and headphone sounds from others).
Cons: Non-adjustable headband (auto-adjust strap mostly works). Some static when you move around. Picks up older (CRT) TV whine if transmitter is close to TV. 900 MHz phones and NEXTEL cell phones interfere with signal. Bass is somewhat boomy and treble is flat, but adequate for TV, most music--needs to be equalized for classical, piano. Slight whooshing noise (compander?) after transition from loud to soft passages. Works poorly when moving behind walls, but OK when still.
As a hearing impaired person, the Acoustic Research AW721 is a wonderful product! Recently, however, they blew a speaker and I had to return them to Best Buy. Unfortunately, they no longer carry this product. Instead, they provided me with the AW772 which was $20 more and had the automatic tuning feature. I thought this would be a great feature. The negatives were that the new product only goes 150 feet and as a result of the automatic tuning feature, the signal would be searching at the most inappropriate times (like when you needed to hear what line the actor was saying on your favorite show). Also, the newer version did not increase the volume loud enough.
As a result, I am returning this upgraded product to Best Buy and purchasing the Acoustic Research AW721 from Amazon.
The Pros of the Acoustic Research AW721 are:
1. Loud enough for hearing impaired people to use without hearing aids
2. Can hear the sound all the way outside while mowing the lawn or picking up the mail.
3. The cushions on the headphone allow me to also comfortably wear them with my hearing aids.
4. Other people cannot hear anything from these headphones while they are on my head. This makes it nice since I like the volume to be turned way up on these headphones! I can be right next to another person without waking them from their sleep, even with the volume at full blast!
Acoustic Research AW721 Cons:
1. Speaker may blow within 6 months
2. Sometimes hard to tune in manually.
Overall, the Pros far outweigh the Cons. I would recommend these to anyone who is interested in listening to the TV or music without interrupting the rest of the household.
The Acoustic Research AW721 headphones are my favorite so far!
