We’ve been banging on about Kleer and their CD quality Bluetooth-busting audio technology for ages now, and so it’s good to see it trickle through into more mainstream platforms.  Mercedes has announced that Kleer-based audio systems will be used in its 2010 E-Class and S-Class cars, offering a choice of two audio streams from in-headrest LCD displays.

Because of Kleer’s multipoint technology, up to five sets of headphones can be paired with any one transmitter, and since its not infra-red like other in-car audio systems it doesn’t require line-of-sight and won’t be overcome on sunny days.  Mercedes will be including a couple of sets of headphones in the car – as well they should, given how much an E- or S-Class will set you back – but any Kleer headphones you have will work too.

That means you could hook up a set of Sleek Audio Kleer-enabled earbuds or perhaps some cheaper DigiFi versions and still hear the same thing, only at higher audio quality and with longer battery life than Bluetooth cans.  Meanwhile Kleer won’t interfere with the Mercs’ WiFi or Bluetooth, either, unlike other 2.4GHz systems.

No word on how much you’ll be looking for to equip your new ride with Kleer, but with the company being acquired by SMSC – who make audio equipment for Audi, BMW, Daimler AG/Mercedes- Benz, Hyundai/Kia, Jaguar, Land Rover, Porsche, Toyota and Volvo among others – we’re hoping it’ll trickle down into cheaper models.
