Sennheiser PC 160 is basically meant for entry level enthusiasts. This headset gives you good quality sound, and should I say I am impressed with it. You have a noise canceling microphone in this comfortable fit device. Dial Volume is fitting and the microphone is non removable.

The Sennheiser PC 160 has two average sound in and sound out 1/8 inches plugs which are merged together and the point they detach has a piece which prevents the both to fall apart in further. The unique part with this Sennheiser PC 160 is tht it has an inline volume control and a mic phne mute button only three feet away from both headphone end.
On the con side, though very less you have unreliable low frequency output; whcih lacks lacks many of the highly desirable perks of Sennheiser's PC 155 USB.
The PC 160 sports a binaural (dual earpiece) design, with an adjustable microphone boom protruding from the left. Its sophisticated silver-on-black color scheme and sleek design match those of most other Sennheiser headsets, though the multihole honeycomb pattern on the outside of each earpiece does tend to look more out of place than harmonious. The slim mic boom swings nearly 180 degrees and unobtrusively parallels the curves of the headband when folded up. Meanwhile, the unit's permanently mounted audio cable connects to just one of the pads--the left--thus freeing your right ear and chin/upper-chest region of annoying wires.
