JBL 520BT – Static Noise & Gap Issue On Right Side

Hello, I’ve been using my JBL 520BT headphones for almost seven months, and recently, I noticed a static noise coming from the right side. While listening to music, it’s not very noticeable due to the sound, but when the headphones are connected to my phone and the volume is completely turned down, I can hear the static clearly from the right side. This issue persists at all battery levels. I have tried resetting and reconnecting the headphones, but the problem still remains. Additionally, I’ve noticed that the inner part of the right side seems slightly open, and when the LED light is on, the gap becomes visible. I would appreciate your assistance regarding this issue.
