ポリコム SoundStation2 Extension Microphone Kit (2200-16155-001)

If you have an EXPANDABLE Polycom, such as the Polycom SoundStation2 Expandable Conference Phone (2200-16200-001), then these are the extra 2 mics that go to the far ends of a long table. Make sure you verify you have the Expandable Polycom before you order these. Make sure you have a Polycom before you order these, for that matter -- these are not generic microphones for tape recorders or such. They work great. I can walk around our long conference room table and the person on the other end can't tell I'm moving. During one call, someone set a paper on top of one of these mics. That made the sound go all funny to the person on the other end, who said so. When she moved the paper off of the mic, the sound was great again. So don't put things on top of these mics. The mute button on these mics mutes ALL the mics. The green indicator light turns red on the Polycom and the other mic, indicating that the Polycom is muted. Anyone can mute and unmute pushing the mute on either mic or the center triangle unit.

It is good but result is not as I expected.

Plug and Play, and extended both the range, and number of participants we can have. Noticeable quality improvement for those far away from the Polycom unit.

These items were exactly what I needed for a small group of people, they extended 6' looked great, easy to set up. Sounded great. I had no problems. Make sure they are compatible with your POLYCOM system before you purchase. Will not work with all systems.

Noting to add, good product.
