Forgive my naivety, but do you really want your ears to vibrate? Korean earphone manufacturer En-Tech obviously think you do, hence these ugly-looking clip-on VIBE 'phones that remind me of something you might wear in a swimming pool. The idea is that you boost your experience of the music by firing vibrations through your head in time with it, a sensation that previously would have required turning the volume up so loud that your ear-drums burst.
At 99,000KRW ($105.81) it seems an expensive way to get your kicks. Your musical enjoyment would probably be far better - and cheaply - improved with a set of aftermarket Sony or Sennheiser headphones, which make up in sound quality what they lack in quiver-power.
