## Customer Reviews

### ⭐⭐⭐⭐⭐ Solid Accessory
*by C***B on August 27, 2019*

This is easy to setup and makes talking great with a variety of bluetooth headphones. I am using a Yealink T46S phone. However, at first I couldn't make outgoing calls using the bluetooth dongel. Seems like the phone wasn't routing sound through the headset / bluetooth. But simple fix was to update the firmware to 66.83.0.50. Works perfectly now. Nice clear signal and sound. Quite happy.

### ⭐⭐⭐⭐⭐ works perfectly!
*by K***A on February 25, 2023*

Works great, obviously easy to use and I’ve had zero problems

### ⭐⭐⭐⭐⭐ Hands free perfection
*by D***B on November 5, 2017*

Purchased these to use with our Yealink office phones and they work great. Installed in less than a minute and will pair with just about any Bluetooth headset regardless of what are listed in the manual...
