Sennheiser PX 100 Collapsible Headphones

The Sennheiser PX 100 Headphones use dynamic supra-aural mini headphones and a slim, lightweight design to provide convenience and superior sound to the traveler or outdoor user. Sennheiser's duoful diaphragms with spiral embossing provide high-resolution sound, while the twin damping technology creates crisp, fast bass response, helped by 80ppi polyurethane and special perforated elements. The ear cups can be turned 90 degrees and closed up, then put into a rugged carrying case that can fit into a shirt pocket. The included headband padding helps provide the perfect, snug fit for your head.
