For instance, when the microphone is muted all the lights are illuminated in red; when searching for a bluetooth device a blue light circles around

This provides great sound and a superior microphone - it connects easily by Bluetooth to my phone and attached USB cable to the laptop.

Multiple inputs, great echo cancelation but also great microphone sensitivity.

Returned this because the microphones were not sensitive enough for 6 people sitting around a table.

Microphone works well

I wanted a speakerphone with a clear microphone and speaker

I compared the iPhone 6s Plus speaker and microphone with the Logitech speaker and microphone and discovered that the iPhone had a much better background noise filter and clearer sound (microphone) than the Logitech P710e

Sound quality of the speaker is about as good as the less expensive bluetooth speakers we've tried, but the microphone on this unit is much better
