I am sure that all music lovers appreciate the freedom that comes with a wireless headset. When using non-wire headphones, whether at home, but especially on the street, you get a 50% bonus to comfort, at least. No wires that need folding, moving or carrying, easy access to all your pockets and more relaxed head movements. In this cold weather, when everyone is dressed from head to toe, the wires can be a real pain in the neck.

Now that phones, audio systems, etc., come with A2DP stereo sound technology, there is really no downside to using wireless headsets. Only in Japan for now, but with no word about a U.S./European release, these wireless headphones from TDK are one solution that you might consider. They are called TH-WR700 and have an ace up their sleeve that allows them to perform better than other Bluetooth headsets, or so says TDK.

This ace is called Kleer and it's a new technology developed specifically for wireless headsets, allowing 16bit/44.1KHz sound quality. This new standard is supposed to offer better performance and lesser radio waves interference. They do work at a traditional 10 meter radius, the same as Bluetooth. The newly launched TDK headphones have an impedance of 32 Ohms and will spare you of up to 40 dB of noise in the signal.

Connecting to any device (including an iPhone) through a standard 3.5 mm jack adapter, these TH-WR700 are supposed to provide higher fidelity sound and improved audio quality for anyone who is willing to trust the Kleer technology. TDK also says that with a standard AA battery, these headphones will work for up to 40 hours and if not in use, the auto-power off function will take over so that you save power. They will be available in Japan starting with March at the price of $190 USD.
