If your office is a hub of activity you’ll need a headset that effectively blocks out distracting background noises, allowing total focus on each and every call. The sound quality of the CC 520 IP's twin ball-mounted speakers means that as a busy professional you can concentrate on what you do best. With an ultra noise-canceling microphone, you’ll also never need to raise your voice to be heard – however loud your colleagues get. This wideband headset improves overall call quality when connected to a wideband supported communication line.

Compared with traditional narrowband headsets, wideband technology offers a more natural and warm sound, and captures more speech details at high and low frequencies. The CC 520 IP delivers natural high-definition sound for superior voice clarity, accented speaker recognition, and reduced echo. The benefits are increased productivity and less fatigue on business calls.

And for added peace of mind, ActiveGard technology protects wearers from acoustic shock and sudden surges in volume. The generously dual-padded headband offers a high level of comfort, while the 300° adjustable microphone boom allows microphone placement to suit any individual preferences. Everyday communicators can relax in the knowledge that the superior sound of the CC 520 IP will prove to be a lasting investment.

3 out of 5 eggspending review

Pros: Sennheiser, other than that, we'll have to wait and see.

Cons: not functional out of the box. you must first buy a correct ''quick disconnect'' cable for the intended application. these start at $30.

Other Thoughts: honestly scoured the internet for information about this before buying the item because there is no information whatsoever about connectivity. product listing should state clearly that you need to order the adapter at the same time, or you will receive nothing but a paper weight.

4 out of 5 eggsCall Center Headset

Pros: Seems comfortable. Sennheiser makes excellent products

Cons: Says it's PC compatible without mentioning that it requires an adapter cord that is not included! That's a pretty important point.
