Review: No problem with connection. Works as advertised - Bought it for a recent long airplane ride from Dubai to Canada. Was Flying on ITA Airways. Didn't need to use because ITA allows direct bluetooth connection, but I tested it on my laptop and it worked as stated. Only problem is trying to remember the directions to connect/pair since I don't use it very often.
Review: La batería es de las que más dura. Funciona perfectamente.Lo volvería a comprar.

### ⭐⭐⭐⭐⭐ Review
*by C***R on 14 January 2026*

The Relay is a nice compact bluetooth transmitter that worked perfectly with my Bose earbuds, but not with my new Apple Airpods Pro 3. The Airpods would connect, but usually without sound. I contacted Avantree and the support was fantastic (I would like to give a huge shout-out to Jeany). Jeany quickly gave me an interim solution and then sent me a set of Avantree SoundJet R1 earbuds to try. The Soundjet R1 earbuds worked very well with my Airpods Pro 3. Given the great technical support, I would have no hesitation purchasing other products from Avantree.
