My hope was that the E8 Gen 2 could replace at least two of the above wireless earbuds.

If you press too hard (which happened to me), the button will get stuck inside the surge and you wont be able to use it anymore (wont pop out again).

On one side of the packaging it says size 7. Really comfortable after wearing it in .
