The TDK WR700 is a portable wireless headphone utilizing Kleer wireless technology and is designed, unlike the majority of high-end wireless sets, to be used on the go as well as at home. Does the Kleer system allow the WR700 to compete with wired sets in sound quality and ease of use or just pave the way another compromise between 'wireless' and 'headphone'? And is it worthy of the lofty $200 price tag?
