Kleer Vs Bluetooth

Why choose a Kleer based audio products and not a simple Bluetooth based product is a question we have had many times... The answer is quite simple!!

Do you like to listen to full CD quality music or to low quality compressed music?

Do you want to enjoy long play time without having to charge your earbuds often?

Do you want to enjoy interference-free listening?

Do you want to easily share your music with your friends?

If you have answered yes to one of the above questions, Kleer technology is right for you!

Kleer® is the only available technology capable of streaming non-compressed full CD quality audio to earbuds;

Bluetooth 2.0 is only able to stream, best case, 320kbps/s of audio packet!!

So, isn't it a pity to have purchased your media player where you can store gigabytes of music, using Apple lossless or Windows Media lossless, and only listen to it with a low quality transmitter?

Kleer® radio protocol has been extensively tested to avoid interference from WLAN, Bluetooth, DECT... while tests have shown that most of the Bluetooth devices are jammed by other radio sources.

Kleer® allows you to connect up to 4 earbuds to the same transmitter! With Bluetooth, you unfortunately have to share one earbud... not really convenient to listen to stereo music.

To stream high bitrate CD quality audio, Bluetooth has to use 20 x 1Mhz channels in the 2.4Ghz band. This uses 20Mhz in a crowded radio band that is used by wireless LANs as well as other Bluetooth devices. A wireless LAN needs 24Mhz. If there is more than one wireless LAN nearby, it will be impossible for Bluetooth to find enough free channels to set up a high bit rate connection. This will result in no audio.

Kleer technology is much more efficient and only requires 3Mhz in the 2.4 Ghz band for CD quality audio. This means it can use channels that are between the bands that wireless LAN's use and can also use channels right at the edge of the band that are not used by wireless LAN's. Tests on the Kleer radio have shown that there is no loss of audio with Kleer even if there are 3 wireless LAN's using all available channels nearby.

Bluetooth's high channel requirement means the transmitter has to operate with a higher duty cycle (transmitter on more often) than Kleer which can use a lower duty cycle (transmitter on less often). This means the transmitter uses less power than Bluetooth. Kleer also use other techniques such as dynamically adjusting the power of the transmitter depending on the distance from the receiver, to minimise power consumption.

A Kleer based earbud will be smaller and lighter than one using Blutooth technology. This is because the Bluetooth radio needs more power and has to use a larger, heavier battery. A Kleer based wireless earbud can operate for 10 hours with an 80mAhr coin cell type battery. This is about half the size of a 1p piece! A Bluetooth radio will operate for less than 1 hour with this size coin cell.

This is why Kleer is best for high quality audio - you will get a much more reliable connection and far longer battery life than earbuds based on Bluetooth technology
