For audio geeks, most of the real fun at CES is over at the Venetian Hotel, where high-end (and not-so-high-end) audio companies demonstrate their products in dozens of guest suites. While the rooms in the Venetian are known for $200,000 speakers, $100,000 amps, and $20,000 speaker cables, you can also hear great speakers and amps for as little as a few hundred dollars.

I had no idea when I wrote my CES Audio Preview how right I’d be. I predicted that Bluetooth and AirPlay wireless technologies would be making their way into tons of new audio gear, and sure enough, at CES both were as common as bad food. Bluetooth and AirPlay make extra-good sense in compact audio systems, which you’re likely to use with smartphones and computers.

Cutting the cable” is a fashionable trend, but Monster is doing it in a different sense: It’s now just going by Monster instead of Monster Cable. True to its new moniker, the company didn’t even mention cable in its CES press conference today. But given the onslaught of cool new products the company introduced, nobody seemed to notice.

Mention noise-cancelling headphones and most people think of large, over-ear models like the Bose QC15. Comfy as those big cans can be, they’re waaaay too big to slip into a pocket or purse. But not all noise-cancelling headphones come in cases sized like jumbo donuts at the State Fair. In fact, a few manufacturers have added noise-cancelling technology to their in-ear monitors (IEMs), using a little “lump in the line” to house the needed electronics.

One might fairly ask, though: Do IEMs really need noise cancelling? After all, when used with tips that fit your ears properly, IEMs completely seal off your ear canals. However, IEMs do most of their noise-blocking at frequencies above 1 kHz. Below that, they’re not so effective at keeping the noise out.
