Comments about Sennheiser PC-121 In-Ear Monaural Headset:
The in-ear unit is light and fits comfortably, though the speaker does not sit too tightly over the ear canal opening. As a result, it's at best only moderately loud, even at full volumes. Frequency response is fine in the normal vocal range, tapering off in volume and fidelity fairly rapidly outside that range. The mike offers a good blend of sensitivity and noise reduction. It's targeted at VOIP, and that is probably its optimal application; I purchased it for use with language software, and the sound out fails to reproduce some of the nuances required for that application. For gaming or the like, it's right out. The cord between the earpiece and the inline on-off-volume remote seems a bit too long, while the cord length between the remote and the pair of color-coded 3.5mm jacks could be longer for use with, say, a tower CPU kept underneath a desk. Most people would probably prefer a Bluetooth unit, but in situations where Bluetooth is unacceptable or unavailable, this unit makes a more than adequate substitute.
