They work very well, in terms of range, audio quality and battery life, Very good product. Tip: to connect the two at the same time, they must be synchronized and connected to each other and the other connects to the phone. A Youtube video would suffice. Haha
These headphones are great! The sound quality is really quite impressive, they are easy to use. They can actually charge your phone, you can answer a call. The sound totally immerses you. I highly recommend them!!
It's so good, the headphones came fast, we try them at a distance and you hear the phone conversations very well and the music on my phone, it is good product with a very good price or, thank you seller
