About the Sennheiser/adidas® HD 25-1 II Originals
If you never thought you could find true happiness in a portable headphone, you probably haven't heard the Sennheiser/adidas HD 25-1 II Originals. These rugged, lightweight cans deliver the powerful, deep bass and crystal-clear sound you need to really savor your tunes whether it's on a home hi-fi system, with your portable player, or in a recording studio.
The HD 25's softly padded, sealed-back earcups reduce outside noise to a distant memory, with no extra electronics or batteries needed. And the left earcup even rotates to allow single-ear listening great for DJs. Extremely robust construction means they'll hold up under heavy use. Plus a unique, split headband design adjusts two separate ways to ensure a highly secure and comfortable fit. To top it off, adidas gave the Originals cool blue accents for a stylish look.
