SleepWave 睡眠耳塞

The seal on these fits tighter than the original ones did, which has cut down on background noise noticeably during the night. They're also easier to clean, so I'm not replacing them as often.

These replacement plugs click in securely and are much more comfortable against my ear for all-night wear compared to the original ones. I sleep on my side and forget I'm even wearing the SleepWave system now.

These plugs are noticeably more comfortable than the original ones that came with the system. They stay put all night without any pressure points. Works exactly as expected for a replacement part.
