My Wearable Breast Pump S2 (T600P)/S2 Pro (T600P+T60A0) speaker cover insert (silicone soft plug) has come loose from the speaker cover?
Use the Nipple Measurement Card to select an appropriate sizing insert, and place it in the flange tunnel. Press it in firmly and evenly until fully seated.
If it continues to fall out, contact support for a replacement.
If you have any other questions, please don't hesitate to contact eufy Support Engineers for further assistance.
