The document summarizes the key advantages of the TDK Life on Record WR700 wireless headphones using Kleer wireless technology. Kleer has a very small spectral footprint of only 3MHz, allowing it to operate between WiFi channels without interference. It can also dynamically switch between 16 available channels. This allows the headphones to maintain uninterrupted high-quality audio even in noisy wireless environments where other technologies may drop out. The Kleer wireless transmission preserves lossless audio quality unlike Bluetooth which uses lossy compression. Kleer also enables up to four headphones to listen simultaneously to the same audio source in a "point to multi-point" configuration.

2. 1. Spectral Footprint Kleer has the smallest spectral footprint, requiring only 3MHz. This is small enough to fit between adjacent WiFi channels. 2. Channel Selection Kleer’s technology can select from any of 16 different 3MHz channels spread across the 2.4GHz spectrum and dynamically switch between them while audio continues to play. Even in high interference environments it has the best chance of finding enough available spectrum to maintain the continuous flow of music. WR700 Advantages – No Audio “Drops” Kleer ™ Wireless Technology Advantage Users want the same quality audio quality from wireless headphones that they get from a wired version. The proprietary Kleer technology integrated into the WR700s delivers. Lossless, uncompromised stereo sound provides a superior listening experience. For any wireless audio application, it comes down to two things; how much spectrum does your radio need (spectral footprint), and how fast can it find sufficient unoccupied spectrum? Vs WiFi A WiFi channel consumes about 24MHz out of the ~80MHz available in the 2.4GHz spectrum. However, WiFi is generally used for data and when WiFi experiences interference, it just stops transmitting and waits for the interference to go away. Not a problem when web-surfing. But if you do that when streaming audio, your music goes away as well!
3. Vs. Other Wireless Technologies WR700 Advantages – Uncompressed Audio Kleer Wireless technology should not be the limiting factor for audio quality. Kleer™ transmits lossless 16-bit, 44KHz-sampled digital audio, the same quality that is recorded on a CD. The lossless compression used in the WR700s only eliminates redundancy from the audio stream such that no information is lost. Bluetooth Bluetooth™ compresses the audio prior to transmission using lossy compression. Relatively high compression ratios can be achieved at the expense of audio quality and at the cost of complexity and power consumption. You can hear the difference. Bluetooth™ audio sounds muddy because many of the high frequencies have been eliminated.
4. Share the Music, Not the Headphones Kleer’s Listen In™ technology enables users to share the listening experience by having up to four wireless headphones listening simultaneously to the same audio source. Simply plug the included transmitter into the 3.5mm headphone port of any media player including iPods/iPhones, laptops and stereo systems and sync all headphones to the source.

5. WR700 – Who is Kleer Who is Kleer? Kleer is a fabless semiconductor company that provides a unique solution for transporting high quality audio over a robust wireless link This patented subsampling radio architecture was designed from the ground up to communicate lossless CD-quality digital stereo audio over a robust 2.4GHz radio link. Kleer’s wireless technology is ideal for headphones like the TDK Life on Record WR700s. It provides superior audio quality and more reliable connections while consuming a fraction of the power competitive technologies. More information at www.kleer.com.
6. WR700 - FAQs WR700 – Frequently Asked Questions Technical Information Q) Do WR700 wireless headphones work with all digital music players? A) Yes, they will work with any digital player that has a 3.5mm (1/8”) audio jack. Note: Because WR700s do not include an in-line mic or controls they are not recommended for use with the third-generation iPod shuffle. Q) How do I sync the headphones to the transmitter? A) 1) Make sure the volume setting on the audio player is low, then insert transmitter into a suitable headphone jack, using the extension cable, if needed. Press the power button. The LED will then start flashing, indicating that is in Search Mode. 2) Press and hold the power button on the right earpiece until red LED on button flashes. 3) Once the headphones detect the transmitter the LEDs will flash in unison. Q) How many headphones can be synced with a single transmitter? A) Our technology enables up to 4 users to share the listening experience from the same audio source. Q) How many batteries are required and how long do they last? A) Four AAA batteries are needed and included with the WR700s. Two in the headphones and two in the transmitter. When listening at average volumes, the batteries will last 30-40 hours. Warranty and Support Q) What is the warranty on WR700s? A) Imation warrants this product against defects for one year from the date of original purchase. For further information or to obtain warranty service please go to www.tdk-media.com. Q) How do I contact TDK Life on Record product support services? A) Support is available 24/7 at www.tdk-media.com.
