| Ultrasone Proline 550 Details The PROline 550 is designed as an improvement on the immensely popular HFI-550. Featuring the same 50mm mylar driver and loud, punchy sound, the PROline 550 also features detachable cables and speed switch earpads. The larger, circular earcups produce a sound that is wider and even richer than the HFI-550 along with great bass response and great isolation.

What we think The Ultrasone Headphone line is incredible sounding stuff! The way the drivers are offset, instead of directly bearing down on your eardrum is really genius stuff. Sound enters your ears more like it normally does, making these a natural choice for anyone who wants to hear a natural sound in a pair of headphones. You won’t just hear a difference, you will hear an incredible difference.
