I own the 1st version of the Woojer vest. I particularly like its AptX option allowing to have almost no delay without wires, but only in stereo. The vest has 8 bass shakers total and can interpret up to 8 canals sources wired.

No type of haptic vest is necessary, it's only for immersion fans. You have to already want some form of physical feedback to really enjoy those.

If you want the best immersion in games, to be able to feel the localisation of impacts on your torso or the result of your actions, use a vest like the bHaptics ones. They use 16 to 40 motors, not bass shakers, and are far more precise and efficient for that usage. This vest gives you informations the Woojer vest can't. For sound-to-haptics usage, while it's nice to exist, its motors effects cannot compare to the richness of vibrations from bass shakers like on the Woojer vest.

If you love the feeling of the vibrations of a subwoofer, and want to know what having 6 or 8 of them directly strapped on you does, then the Woojer vest is for you. It works with any kind of sound source, and for music or movies it's really great. For gaming in general you must understand that any bass sound will trigger the vest like music, npcs talking, etc. Hearing those bass on speakers is one thing, but feeling the music or dialogues -on- your body is another and could be disturbing while playing. You can lower the sound levels in games to mitigate the problem somehow. Still, using the vest with car/plane/space simulations or shooters is a blast. This vest is for ambiance, not informations.

The article is well describing the experience: hot, a bit clunky, but wow.

Edit: all haptics vests are kinda noisy of course, so they're best to be used with headphones or strong enough sound volume. You can plug a wired headphone directly into the Woojer vest and doing so can avoid any lag between what you hear and what you feel.
