The CX500 will attenuate about minus -10dB to 15dB of ambient
noise depending on the quality of the ear canal seal achieved. They
come with different sized silicon eartip sleeves in single &
double-flanged designs (each in S/M/L) included in the packaging
and feature a volume slider integrated into the cable which folks
who hate fiddling with the volume control on the player will
appreciate. The cord is about 4ft long and terminates to a
right-angle gold-plated 3.5mm mini-plug. Also included in the CX500
accessories kit is a cable shirt clip, handy cable winder, and
carrying pouch for convenient handling & storage.

From my point of view, I just like the sound that CX-500 gives...
the sound isolation is wonderful coupled with the good body that
the music gave... superb earphones.
