Not recommended for bluetooth. It has no noise cancellation for bluetooth phone calls.
I tried two different types of speakerphone and both performed poorly over Bluetooth. When using this for phone calls, customers can hear all keyboard typing noise in the background with basically no cancellation. During Teams calls via USB, the noise cancellation is good enough. During a USB teams call, it will cancel background noise so long as you aren't quiet for a minute. If you are quiet for a period, it gets more and more desperate to hear something from you so it turns down the cancellation and turns up the mic sensitivity.
The companion app did all the firmware updates and did not improve any of this. And there are basically no settings in the companion app regarding noise cancellation.
