Ultrasone PRO 550i

The Ultrasone PRO 550i feature 50mm Mylar sound transducers that deliver a powerful bass and allow for precise localization of instruments. It can be used in several environments for applications such as recordings, in studio mixing, or listening anywhere you go.
With the closed design, background noises are systematically suppressed and the headphones produce a clear, natural sound. The impressive sound has intensity and strength.

In addition, 2 detachable cables, one coiled with a 1/4" plug and one straight with a 1/8" mini-plug connector, a pair of velour earpads, and a transportation box are included.

Portable Design
The headphones fold down easily into the included hard case for convenient storage and travel

Pro-Quality Sound
Large 50mm Mylar drivers, combined with Ultrasone's S-Logic Surround Sound Technology puts you right into the center of the music, ideal for tracking bassists and drummers. Instead of piping sound directly into your head, the S-Logic Plus technology creates a rich and detailed soundscape that seems more like you're listening to live music than headphones

Ultra-Low Emissions
The PRO 550i headphones have ULE technology with an MU metal shielding to significantly reduce the amount of electromagnetic emissions produced by the headphones; up to 98% less than standard headphones. This is excellent for professional users who spend the majority of their day wearing headphones
