Title: Sennheiser PX 100 Collapsible Headphones
Review: These headphones are convenient to use, comfortable on ears, and deliver melodious sound without much of hiss. However, the utility of the set will greatly improve if it includes a volume adjuster -- so one does not have to go back and forth to iPod to adjust volumne.
