With superior musical detail resolution across the board and more precise dynamics, the CX 400-II Precision Black ear-canal phones target music afficionados wanting to upgrade the sound quality of their portable audio devices. The wide array of ear adapters (two types) provided in the package allow for a personalized fit and excellent passive attenuation of ambient noise. To add to your listening convenience, a volume control has also been integrated into the cable.
