The 7 coolest things Sony announced at CES 2015 (pictures)

LAS VEGAS -- At CES 2015, Sony unveiled new wearable products, 4K recording camcorders, and a 4K projector, and more.

Featuring advanced optical image stabilization and a cheaper price than the FDR-AX100, the new Sony Handycam is a compact 4K camcorder that will be available in February.

With the popularity of high-end action cams, the $500 FDR-X1000V features live-streaming capabilites over Wi-Fi and loop recording.

Shooting 4K video is one thing, but what about projecting it? With the VPL-VW350ES, you can project 4K recordings for the price of $10,000.

Though the Smartwatch 3 has already been released, Sony took the wraps off a spiffy new steel variant. Though it lacks a heart-rate monitor, it does have a standalone GPS for sports apps and Sony's Lifelog fitness software.

Designed for runners, the B-Trainer protoype is a waterproof headset that's decked out with fitness sensors and can play music via its onboard storage.

Holding onto that Walkman dream, Sony announced the NW-ZX2, a high-res audio player that will be available in the spring for more than $1,000.

Touted as Sony's slimmest LED TV, the XBR-X900C 4K TV measures 4.9mm at its thinnest and comes in 55-, 65-, and 75-inch variants. As a smart TV, it also runs Android Lollipop and will be available in the spring.
