Bluetooth's been a boon for headphones, 'cause lots of people love headphones but nobody loves cables. It hasn't taken off in the in-ear monitor market, though, 'cause almost all Bluetooth IEMs have a clunky module that holds the Bluetooth electronics and the amplifier-and nobody loves clunky modules.

I've evaluated at least 57 soundbars. That experience has taught me there are two attributes a truly great soundbar should possess. First, it should sound good. Second, it should work like it's part of your TV-i.e., it should power up and shut down when your TV does, your TV's remote should control volume and mute on the soundbar, etc.

By this measure, there's never been a truly great soundbar.

Sonos-known for network-based audio devices such as the Play:3-has attempted to create a soundbar that would meet my definition of "truly great." How confident is Sonos that the new $699 Playbar will work perfectly in concert with your TV? Pretty confident: The Playbar doesn't come with a remote.

Home theater nuts can never have enough subwoofers. But the average household isn’t run by a home theater nut. Usually, the decisions about what goes into the living room are made by someone for whom audio gear is only slightly more welcome than cockroaches. For that person, even one sub may be too many.

Atlantic Technology built its PowerBar 235 soundbar precisely for households split by the conflict over good sound versus bulky audio gear. The PowerBar 235 is one of only a couple of soundbars designed to deliver satisfying bass response without a subwoofer.

David Chesky's name is practically synonymous with audiophile recording and the quest for a purer, more natural sound. Instead of close-miking instruments, recording them on multiple tracks, adding reverb, and mixing it all down, he records in great-sounding spaces in pristine stereo.
