The CX500 are the ultimate Sennheiser earcanal headphones. With a wider frequency response for fabulous sound quality they get the very best from your portable music player. Extended ear adaptor set supplied to combat unwanted ambient noise interference. For added convenience there is also an in-line volume control, cable winder & carry bag.
I purchased from both LUCASTICA and SMARTDEALS and comparing them to the online replica manuals...they're pretty genuine.
Your choice folks!
