My choice is TREBLAB XR500. Initially I was skeptical of the earpieces, but they fit really nicely. I bought them on Amazon and was glad to get it on time. Charging is fast as well though (30-60 minutes). Sound insulation is a happy medium, just as I like. They are also super comfortable. My friends especially like its design, so definitely recommended.
If it's bluetooth you really need to connect it with something or it will really not happen anyway for so many reasons out there, I do not really see what can be done to change that much anyway. Care to see that better or not ? I do not know.
