Gefen Backs Both Horses: UWB and WHDI

Home theater fans who have been looking for a way to push their high-definition video around their systems (and to different rooms) without the hassles of stringing cables (or drilling holes in the walls) have faced a choice between Ultra WideBand (UWB) and Amimon’s Wireless HDMI (WHDI) technology. Although WHDI has been garnering industry support recently, video connectivity developer Gefen has gotten tired of waiting for a resolution, so it has decided to offer both UWB and WHDI products for folks who just can’t wait to be wireless.

First up, the GefenTV Wireless for HDMI Extender is a two-box system with a sender unit connected to a high-definition video source, with a receiver unit connected to a high-definition display. The system can handle 1080i video with HDCP with performance delay no worse than wires system. In addition, the solution doesn’t require line-of-sight between the two units, so its ideal for situations where equipment needs to be out of sight or in awkward locations. The WHDI technology operates in a 5GHz unlicensed band and has a range of up to 30 meters

Now don’t get confused by the name: Gefen’s Wireless for HDMI Extender uses UWB technology from Tzero Technologies; it lets users push 1080p video with 5.1 multichannel audio wirelessly over distances up to 10 meters, and includes interference cancellation technology so the system won’t be tripped up by nearby Wi-Fi networks, cordless phones, and other devices. The Gefen Wireless For HDMI Extender can also upconvert standard definition video, and complies with specs from the WiMedia Alliance, the HDMI Forum, the FCC and is even “Hollywood Approved” for copy protection.

As a solutions provider, Gefen may be making a solid business decision to let its customers choose what technology they want to use, rather than coming down on one side of the fence or another. However, we do wish they would announce availability and pricing information.

New $129 Moto Buds+ tap Bose for boom and Dolby for head tracking

The Moto Buds in Forest Gray.

Three new phones under the Edge 50 branding weren't enough for Motorola this week. The venerable manufacturer also dropped a pair of earbuds to go along with the new Android fare.

The main contenders for North America will be the Moto Buds+, which are available now for $129 in the U.S., and $179 in Canada. They look as you'd expect wireless earbuds to look; that's worth mentioning because Moto had some wood-clad phones in its drop this week. They're sleek and stylish and apparently available here only in Forest Gray, though press images show other colors, too. (More's the pity -- those other colors look slick.)

Anker’s Soundcore Sleep A20 earbuds are next-level sleep aids to block out noise

Anker Soundcore Sleep A20 earbuds worn while sleeping on side

If you had asked me years ago what kind of earbuds I'd be wearing while I sleep, I would have called you crazy. To sleep, I need silence, and anytime someone has a TV or tablet on or makes any noise, it makes me restless. With two kids and a wife who are all loud sleepers, it's safe to say I often have trouble sleeping. Believe it or not, there are earbuds for that. Anker's Soundcore Sleep A20 TWS earbuds, for example, are the second generation of its sleep-aid product. They're specifically designed to be worn while you sleep, thanks to a sleek form factor that doesn't protrude out of your ears or create discomfort while resting your pretty little head -- they're meant for side sleepers.

They also purportedly offer much more substantial snoring reduction than the previous generation via soft ear tips and ear wings that help block out ambient noise. If you like a little background audio, they pair with a mobile device that’s using the Soundcore app and allow you to play sound effects to serenade your slumber. A 4-point noise masking system uses not just the twin-seal ear tips and wings but also masking sounds and smart volume controls to drown out distracting noises. If you snore or your partner snores, it won't wake you up anymore as long as you're wearing these.
