TDK WR700 uses Kleer technology to give the listener lossless audio quality without the clutter of wires. Despite their simplistic design, the headphones look like a product to be taken seriously. The construction is mostly plastic but the dull grey matte finish gives them that slightly industrial look. The plastic used is of fairly decent quality and there are no noticeable chinks even with the folding mechanism. While the headphone itself feels light and comfortable (despite housing two AAA batteries), the transmitter is bulkier than we would’ve liked.
As for performance they provide good isolation, and apart from being wireless, they’re competent in their right as decent headphones. A little bass heavy, they handled all frequency ranges surprisingly well – right from the deep 30 Hz to the ear splitting 15,000 Hz samples. Chris Rea’s smooth voice comes nicely layered, retaining it’s husky timbre over the bass riff in Call On Me. The bass kick and reverb on the heavy drum at the beginning of Brutal Hearts was lovely too.
While instrument separation is very good for a compact portable, sound staging is perhaps one of the only areas in which this set of headphones falls short. Music appears to be playing from a source very close to you; somewhere above. Still, overall this is one of the better sounding headphones we’ve laid our hands on, and probably the best wireless pair till date. As for range and battery life it gave what is promised – about 30 feet and 30-plus hours. There are no pops or crackle in sound quality while pushing the range envelope. They just stop streaming after a point.
At Rs 6,900, they’re a little expensive, but if you’re looking for a wireless solution without compromising on sound quality, it makes for a decent purchase.
