My headphones recently broke and I'm looking to buy the exact same type, but I don't know anything other than the fact they are JBL ear-in headphones. I have Googled its description, I have tried to find information by looking through the JBL website, and I have looked up "headphones stack exchange" to find where other people are asking questions like this, but most of the results I've seen are about trying to repair, troubleshoot, or design in headphone-related issues. I haven't had any luck so I've decided to turn to Meta.
