Works very well

Fast connection, good sound, simple to use. I am using Jabra 75 Elite and it works perfect. Now I can actually understand what I’m hearing in a movie on the plane.

Best PlayStation portal headphone adapter to Bluetooth

Once I was shown how to hard reset the relay everything is working like a charm. I have already recommended your product to several PlayStation portal discords I belong to. They all were impressed with your customer service and product quality. Thanks again for making an amazing product and customer experience :)
