Thanks to the increasing prevalence of Bluetooth-compatible devices (such as iPads, iPhones, and nearly all other smartphones), wireless headphones are starting to proliferate like never before. However, the only problem with Bluetooth is that it takes already compressed audio (usually MP3) and compresses it even more, so it loses a little something in transmission.

The Good

Wireless headphones with Kleer technology; good sound quality, especially for wireless headphones; easy connection; compatible with all audio devices using a 3.5mm headphone port; adapter for AV receivers; cloth carrying case included.

The Bad

Requires using the included receiver dongle, which is somewhat bulky; transmitter and headphones each require two pairs of AAA batteries; headphones could be slightly more comfortable.

The Bottom Line

Despite a few shortcomings, TDK's WR700 wireless headphones--which use Kleer wireless technology instead of Bluetooth--deliver good sound for a reasonable price.

On the other hand, a company called Kleer promises to deliver wirelessly uncompressed digital audio at CD quality. It says that when you compare it with other technologies like Bluetooth, you'll hear the difference, and--at least with TDK's Kleer-powered WR700 wireless headphones--we did.

Of course, the problem with a fledgling standard like Kleer is that--unlike Bluetooth--it's not built in to a wide range of mainstream devices. To get around that, you'll need to connect the included Kleer transmitter--it's powered by two AAA batteries--into your in-home stereo system or mobile audio device and sync it with the headphones, which are also powered by two AAA batteries. You don't have to worry about "pairing" the device like you do with Bluetooth; the headphones connect very quickly to the transmitter.

Ergonomically, the headphones are fairly comfortable--and they seem pretty well-built--but they aren't supercomfy and we found ourselves making little adjustments after listening to them for a while. That said, they have a nice padded headband and earcups that sit on your ears but don't totally cover them. Like most closed-back on-ear or over-the-ear headphones, they can get a little steamy after using them for several minutes, particularly if you're using them in a warm environment.

When you're not wearing the WR700s, the earcups fold flat, and TDK throws in a cloth carrying case for easy transportation.

While the transmitter is simple to set up and stows easily enough, it does have one drawback: it's somewhat bulky (after all, it's capable of housing two AAA batteries). The size of the transmitter won't bother you when you're plugging it into a home AV receiver (a phono adapter is included, along with a short extension cable that allows you to access more deeply recessed headphone jacks). But when you've attached it to an iPhone or another mobile device, it does look a little clunky. It's a shame it isn't a bit more compact, or that Kleer doesn't have the marketing muscle to have it built in to more devices, as Bluetooth is.

TDK says that you should get about 30-40 hours of listening before having to change the batteries, which is good. And the headphones have a range of about 33 feet, which is equivalent to what Bluetooth offers. It's also worth noting that if you happen to have multiple WR700 headphones, you could plug in one transmitter to a single source and have up to four people listen at the same time. This is one of the benefits of Kleer.

As noted, the other benefit is the sound quality. While the WR700's are a little bright and have a slightly canned sound (they don't sound "open," which may cause some listening fatigue) they deliver rich sound with good detail and strong bass. What impressed us was that we didn't feel we were listening to wireless headphones, which is praise in itself.

So despite some small shortcomings in design, we liked TDK's WR700 headphones and for the price (around $120 online) we think they're a decent option for people looking for a set of wireless headphones for late-night TV watching or music listening--or just to have the freedom of not being tethered to your mobile device.
