Wireless earbuds present some major challenges around where to have the electronics necessary for the connection, along with the battery. Most modern designs have the electronics as a "collar" around your neck, but audiophile favorite Klipsch has taken a different tact with its slick R6 wireless bluetooth earbuds, having the electronics tucked behind your ears. Dave Taylor of http://www.AskDaveTaylor.com/ tries them out and finds that they're quite good, particularly with the addition of aptX and AAC decoding support.
