Las Vegas - Pineapple Electronics is showing its Rumble K and Rumble KW in-ear headphones here at International CES, North Hall booth 4430.

According to the manufacturer, the headphones differ from most others on the market because they feature "bone conduction transducers," said to transmit sound through the listener's bones, rather than through the air. Pineapple claimed the technology allows the headphones to transmit a fuller range of sounds than most other headphones. The company also said the technology helps reduce the risk of hearing loss typically associated with headphone use.

The Rumble K features a frequency response range of 20Hz to 20,000Hz. The Rumble            KW offers a frequency response range of 50Hz to 20,000Hz.

Pricing information will be available at the show.
