Kleer technology is a wireless system that provides wireless streaming of full CD quality audio. It can be used in headphones and portable devices with possible applications in wireless speakers, streaming video and others. Kleer operates in the 2.4 GHz range and is capable of streaming 44.1 kHZ, 16-bit audio with greater resistance to interference, longer battery life and better performance than Bluetooth. It is also robust enough to permit multiple listeners from a single source. In my recent review of the TDK WR-700 Wireless Headphones
, I noted that as many as four wireless headphones can be connected to a single source. Other headphone manufacturers such as Sennheiser also employ Kleer in a few headphone models. Kleer technology appears to be a serious competitor to Bluetooth in terms of signal reliability, longer battery life and better overall sound performance.
