Query: I'll Buy From AYL Again

I liked them when I received the headphones, but in 4 months they will no longer connect to any bluetooth device. I did just email AYL today about this to see how they back their product. Update- They sent me a new pair of headphones to replace the defective ones, this happened pretty quickly. My only complaint about that process is in the email they send you, their English is terrible. It was difficult to understand what they were telling me. However, they did back their product! My other AYL Bluetooth speaker has worked great from the start and is still great today. Overall, I'm happy with the products I have purchased from them.
