The PX 100-II stereo headphones from Sennheiser provide high-quality audio in a lightweight and portable design. Ideal for listeners on-the-go, the headphones feature a Fold n' Flip collapsible design that folds down to about the size of a pair of eyeglasses. Patented DuoFol drivers and Open-Aire acoustics provide crisp, dynamic audio with a wide frequency response.
The steel-reinforced headband provides terrific durability, but also features comfortable padding and can be adjusted to fit virtually any head size. The on-ear cushions allow you to maintain awareness of the sounds around you and provide lasting comfort.
The single-sided cable is designed to resist tangles and features a standard 3.5mm plug for compatibility with CD players, MP3 players, computers, and more. A convenient soft carrying pouch is included for storage.
