I tried to imagine the S9W at home but quickly realized my rustic family room is no match for its art-gallery vibe. Although I have to admit, when I first laid eyes on its magnificent 82-inch Ultra HD screen with its cinematic 21:9 aspect ratio, I wondered why it was perched, just shy of teetering, on a compact refrigerator. Refreshments at hand, perhaps? No, that wasn’t it. (Not even close, knucklehead.)

AT A GLANCE
Plus
Extra boom for bass hounds, especially fans of hip-hop and dance music
Minus
Clunky
Can create a buzzing sensation when worn on a belt
One more wire to deal with

THE VERDICT
Woojer is not for everyone, but it can add a visceral element to mobile listening that may appeal to gamers and fans of dance, hip-hop, and other bass-driven music.

Can a small device that clips to your belt produce the visceral sensation of a live musical performance or the deep, pulsating bass felt in a dance club? Can it wow mobile gamers with spine-tingling bass?

Kickstarter-funded Woojer (“See Me, Feel Me,” April 2014) aims to do just that with a “wearable subwoofer” that connects between your music player (or any audio source) and headphones. Technically speaking, Woojer is a polyphonic tactile transducer that converts audio frequencies below 500 hertz into low-frequency vibrations to “make your body feel like it is exposed to high acoustic energy.”
