The CX 985 In-Ear Headphones made by Sennheiser are in-ear type headphones that feature dynamic transducers and a frequency response of 16Hz - 24kHz.
Built from real metal alloy housing, the headphones are lightweight and ergonomically engineered to blend smoothly with the shape of the head and upper body movement. Different-sized ear tips let you choose the best fit for premium noise isolation and optimum frequency response. For enhanced bass there is an extra set of ear tips included. A low harmonic distortion rate lets you focus on the details of your favorite songs and allows you to listen at safe levels without sacrificing details.
The tangle-resistant Y-style cable stays out of the way and the included clip can be attached to a jacket, pants or shirt for a reliable hold. On the cable there is a built-in volume control so you can quickly adjust your volume settings while on the go.
