Apple introduced the AirPods Max not so long ago and while the sound quality is better than most over-the-ear headphones out there, you may have questions regarding the wearable's hardware. With that said, the team over at iFixit has posted a detailed teardown of the AirPods Max. Surprisingly, the AirPods Max received a pretty decent repairability score compared to the AirPods and the AirPods Pro. In addition to this, the AirPods Max headbands can also be removed easily.

The iFixit team discovered that the process of tearing down the AirPods Max is a bit different compared to other headphones. The earcups of the headphone feature screws which when rotated releases a wedge on the other side. Yes, you're not supposed to do that because it would just make it difficult for you to undo. The teardown reveals that the battery of the AirPods Max is fixed inside the right. The battery is a mere 664mAh and made by Sunwoda. The team also posted a video in which it shows the AirPods Max's hinge in action.
