The Sennheiser PX 100 Folding Headphones is a pair of open, dynamic supra-aural mini headphones for portable audio players. Their outstanding sound reproduction and foldable design make them ideal for outdoor use and travelling.

With Sennheiser specialities like spiral embossing diaphragms and a Kevlar reinforced cable, the overall the sound is punchy with an enhanced bass response and laid back treble - making these headphones ideal for acoustic and classical music. The over-the-head design is extremely comfortable especially as the headband comes with padding too.

But one of the best features of these headphones is their twist and fold design so that they close down into almost nothing, making them easily transportable for slipping into pockets or bags.
