JBL Tune 500BT Headphones Broke Easily

I can't get in touch with customer service, and my emails go unanswered. I bought the JBL Tune 500BT headphones on January 13, 2023. I didn't force them while adjusting them to fit comfortably, but they broke. They've never been dropped or scratched, so seeing such a supposedly high-quality product deteriorate so quickly is disheartening. Fortunately, I still have the box and receipt, and the warranty hasn't run out. I'd like either a replacement or a refund. I bought these headphones because I liked them, and it's disappointing that they broke so quickly. I'm hoping that a reputable company like yours will not dismiss my complaint and frustration. Thank you in advance for taking the time to read this.
