Mainstream movies and TV shows in higher than high-def are still out of reach, Carnoy says. But screens like LG’s 55″ OLED model show crisper colors; sports broadcasts look like you’re there. All for the ‘low’ price of $12,000.

Apple isn’t at CES, but there are tons of iPhone accessories, like the Rewind bluetooth earbuds. They have a retractable cord which maker Felt says will keep you from getting all tangled up while listening on the go.

Tech you can wear looks to be a trend: Vuzix is showing off what looks like a long Bluetooth earpiece that’s actually an Android screen over one eye that displays text and email alerts, apps and augments reality.
