Etymotic ER3 SE/XR シリーズ交換ケーブル

I love that the MMCX connector has a special key that locks into place, making it much more secure than standard cables I've used before. The sound quality is just as clear as the original cable, so no complaints there.

The locking MMCX connector clicks in with a satisfying snap and stays secure, unlike some universal cables I've tried. It solved my intermittent audio cutout issue immediately. Sound quality is perfectly clear through these.

Putting these on was a bit fiddly at first, but once they clicked into place the connection feels incredibly secure. The cable itself is light and flexible, which makes a huge difference for comfort during long listening sessions.
