I was hoping to have an awesome experience, but unfortunately the team didn't do it's due diligence when first diagnosing the problem with my headphones. They were prompt and let me know that the usb port and board needed replacing and i promptly received my headphones back. After just 5 minutes of use, the device started to malfunction and I had to re-send my headphones back in. They let me know that there was corrosion on the battery and they had to replace that (which they did free of charge). Overall - this would have been a great experience, but unfortunately, a lot of trouble could have been avoided if they caught the battery corrosion the first time.
