The PRO 550 headphones from Ultrasone provide professional-quality audio in a lightweight and comfortable design. The headphones can fold down into the included hard case, which also has room for storing accessories. The headphones are fully adjustable, and have comfortable around-ear speed-switch earpads. A spare pair of earpads are included.
The headphones use large 50mm Mylar drivers to provide smooth, natural sound with a wide frequency response that offers deep bass and crisp treble, ideal for tracking bassists and drummers. The headphones use Ultrasone's proprietary S-Logic Natural Surround Sound technology to provide a realistic soundscape, creating the impression that you're listening to high-quality speakers that are actually several feet away. This technology also produces the same perceived volume levels at a lower dB rating, allowing you to set the volume on your player a bit lower, potentially reducing the risk of hearing damage.
Other great features of the PRO 550 include MU metal shielding, which reduces radiation emission by up to 98% compared to other similar headphones on the market. This is an excellent feature for users who spend a great deal of time using headphones. The headphones include two single-sided detachable cables; one straight and one coiled. Each cord has a standard 1/4" stereo plug, and a 3.5mm mini adapter is included.
