Yeah, that's been my experience with KZ bluetooth in past. If remember correctly, it's something to do with KZs placement of the antenna internally. I have all 3 of the TRN and none of them have that issue fortunately. The range is decent but not as good as some of the higher end bluetooth earbuds. You won't have connectivity issues with your phone or amp in your pocket though like the KZs. I'm sure you can return it on Amazon with no problem. Good luck!
