Evergreen Technologies has released its $60 RumbleFX Force Feedback headphones, which rumble "with magnified bass sounds such as explosions, rockets, gunshots, and more." The headphones, which plug into any stereo mini-jack, provide a built-in power amplification controller that allows users to fine tune the vibration and volume based on personal preferences.

Buy panasonic
If you want a good pair of headphones with vibrating feedback buy the Panasonic RP-HT970 headphones they're studio quality sound great for everything. They have two sets of speaker drivers one for normal use and a second pair that when the amplifier built into the wire is turned on (3 settings off mid and max)amplify low frequency sounds with sound and vibration very cool.
