As always a first class product from Avantree
I have used Avantree Products for years. This is by far their best. I like the fact that it charges by way of USB-C instead of micro USB, finally. Avantree support has proven excellent over the years. The product works great. Highly Recommended!

Somewhat disappointed but the product is what is advertised
Although looking after purchase I found it is in the details, I did not see that they only reach 30 feet. My kitchen is 35 feet away from my TV and I lose connection. I can not seem to figure out how to change the ear-cushions to a smaller size. These seem to hurt my ears. There is no mute on the necklace, only up/down and off/on buttons. Every night they must be turned off and the transmitter also needs turned off or else in the morning they are dead! Last but not least the sound isn't a quality sound, it's a bit tinny. They will do until I find another product to replace them. There seems to be limited options for sets of two. I had a set of Duets and they break. I had to JBWeld the actual plastic head set back together. Both headsets eventually broke. They did last more than the 24 month warranty.
