Inside, the first thing to catch our eye is adhesive. Guess that's why Nothing made the Ear (1) only partly transparent—adhesive is not very pleasing, and they know it!

The second point of interest is a button cell battery, similar to what we found in the AirPods Pro and the Galaxy Buds Pro.

As long as this is not a custom cell, this might be a good sign for replaceability.

In order to continue, we need to disconnect the in-ear portion from the stem. And it looks like we're lucky with adhesive for once ...

This red glob glues a tiny press-fit connector to its socket and prevents it from accidentally disconnecting during a fall.

With delicacy, and without any heating or tearing, we manage to maneuver our tweezers around the adhesive and disconnect the flex cable. Huzzah!
