Energous and Witricity have developed new ways to charge smartphones, tablets and other small devices without needing wires to plug them into an outlet. Energous’ WattUp technology allows users to recharge phones in special cases or receivers that can pick up signals from a transmitter that is plugged in more than 10 feet away.

Besides an interesting push for wireless in 2011 with AirPlay adoption and a few compelling Bluetooth-equipped devices, Engadget suggests the Consumer Electronics Show hasn’t seen too much exciting in the audio realm over the last few years. In its preview of CES 2013, the tech blog doesn’t expect anything “exceptionally innovative on a widespread scale,” but notes a few items worth watching.

“You can count on a bigger assortment of wireless solutions, and likely the first big showing of the end of days for the speaker dock — excluding anything that Apple’s Lightning connector might make its way onto,” reports Engadget. “Still, the idea of the dock can live on with additions like Qi inductive charging, as we’ve seen from the likes of JBL and TDK already.”

More celebrity-endorsed headphones are expected, and major companies like Sennheiser will join the fray with headphones “in the $100 to $400 range with street-focused looks and audiophile DNA.”

The Las Vegas Convention Center will include space featuring HiFi audio, “with many boutique brands showing off their latest and best — usually with price tags to make your wallet cringe.”

“What has us really excited, though? We’re hearing talk that transparent speaker technology is poised to make a comeback,” notes the post. “Imagine the shell of your tablet, smartphone or laptop also serving as an essentially invisible speaker. Aside from the prospect of even svelter devices, the tech has the potential to sound miles better than the tinny-sounding speaker drivers most of our gadgets currently use.”
