These earbuds sound good, but I wish I would have purchased the model without the in-line volume control (CX300). Within a few days use, the rubber covering the wire on both sides of the volume control had pulled out, exposing the bare wire and causing it to frey. It will be only a matter of time before the wire shorts.
With superior musical detail resolution across the board and more precise dynamics, the CX 400-II Precision Black ear-canal phone target music aficionados wanting to upgrade the sound quality of their portable audio devices. The wide array of ear adapters (S/M/L sizes) provided in the package allows for a personalized fit as well as an excellent passive attenuation of ambient noise. To add to your listening convenience, a volume control has also been integrated into the cable.
