The Soundstation2 conference phone offers superb audio performance for meeting environments up to 8-10 people maximum. As a second generation model the Soundstation2 is rated at around 40% louder and clearer that the first generation version, and with improved protection against radio-wave interference, the Soundstation2 is free from "Mobile Phone Buzz". Overall, this model deserves to own the lions share of the market for wired solutions for small / medium environments.

The ClearOne philosophy is to offer multiple connected systems for larger spaces. The advantages are numerous: both units can be controlled from a single console, each console represents both a speaker and microphone presence for fuller audio across a larger space, and the wired unit can have a 3rd unit or even a 4th unit added for even larger environments, and finally, with additional power bases you can split your units back into single unit models for small spaces. This solution offers maximum flexibility and increased sound coverage.

As part of Polycom's "HD Voice" product family, the VTX 1000 offers greater pickup range for up to 20 people, and sound processing that adapts to your environment. With wideband sound (80-70,000Hz compared to standard 300-3300Hz) when you connect two VTX units at each end of a call for superior audio quality, and the ability to expand with extra mics and subwoofer, the VTX is a Premium executive-quality solution for medium-large spaces.
