JH Audio's JH 13 Pro earphones have six drivers — two woofers, two midranges and two tweeters, which gives them "dynamics that are so much more visceral" that any other in-ear headphones CNET's Audiophiliac has ever heard.

Of course, any headphones this high end require custom moulds from an audiologist, which adds another $US150 to the price. Steve says they're worth $US1100, not just because they're hand-built and designed Jerry Harvey, who founded Ultimate Ears, but because you'll get 10 years of use out of them — which, looked at from that angle, isn't so bad.
