Before finding a way inside these plugs, we remove the silicone eartips.

The eartips sled over an oval groove outside the earbud head, providing a relatively large sound opening.

Since these are sled-over tips, they should be replaceable with any aftermarket tips you prefer. That's worth something (for Nothing).

Since the vise and heating procedure was a good choice in previous earbud teardowns, we decide to put a little bit of pressure on the Ear (1) to get inside the opaque head.

Success! With the help of a halberd spudger, we can peek into previously hidden components.
