Would you buy this?

Wireless headphones have been on the market for a long time, but they have generally lacked the sound quality of their wired components, making them easy to overlook for anyone concerned with crisp audio quality. However, TDK's WR700 headphones utilise Kleer wireless technology and not only look good and feel comfortable, they deliver excellent audio.

The TDK WR700 wireless headphones are an over-the-ear model with a stylish black and silver design. Build quality is excellent, with matte silver and black plastic surrounding the ear cups and sturdy-feeling hinges below the headband.

The TDK WR700 wireless headphones are quite large, but they are comfortable to wear for long periods. Both the ear-cups and the headband are finished with a soft, leather-style pad filled with foam, so the headphones don't dig into your head or ears. Like most of these leather-style ear pads, it means your ears do become rather hot, even after just a few minutes of use — the only real downside when it comes to comfort.

The TDK WR700 utilises Kleer wireless technology, which transmits digital audio signals without compression. This is made possible utilising a small transmitter that plugs straight into a standard 3.5mm headphone jack. Powered by two AAA batteries, setting up the TDK WR700 is as easy as plugging the transmitter into your device of choice and turning the power on. Unlike wireless Bluetooth headphones, this technology pairs almost instantaneously and up to four sets of headphones can use a single transmitter. The technology provides a wireless range of up to 10 metres, similar to Bluetooth. We didn't experience any interference during testing, despite using the headphones alongside assorted other wireless equipment.

Once you've connected and powered up the transmitter, you simply turn on the headphones (also powered by two AAA batteries) and they automatically pair. You can adjust volume using the + and – buttons on the right ear cup. TDK rates the WR700's battery life at up to 40 hours — we recommend using rechargeable batteries both for the longest possible life and best value.

Audio quality is amongst the best we've heard from wireless headphones. Though they won't impress audiophiles (even though they are classed as enthusiast headphones by TDK) sound is crisp and clear and bass reproduction is particularly impressive — it's punchy without overpowering other elements of the music. Upper frequencies are also clear.

One downside to the TDK WR700 headphones is the lack of active noise cancellation. Despite this, the insulation of the padded ear cups does a reasonable job, blocking out most background noise provided you are listening to music at a medium to high volume. If you're a regular public transport user, you may require stronger noise cancellation. The WR700 also has average sound leakage — at medium volume levels, the audio can clearly be heard by any surrounding people. The headphones also require a relatively high volume to produce the best sound quality, unlike many IEM headphones which can produce excellent sound at generally lower volume levels due to the seal in the ear canal.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

Steph Mundell


The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

Simon Harriott


My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
