The Alpine SleepDeep is a reusable sleeping earplug built around an oval shape that follows the ear canal rather than a round foam cylinder. A noise-reducing gel inside the soft body gives it an average attenuation of 27 dB, aimed mainly at snoring and low rumbling sounds. It is washable and rated for about 100 uses, so it competes with foam plugs on running cost and with moldable silicone on comfort. Side sleepers are the target buyer, since the soft body sits flatter against a pillow than hard flanged plugs.

Ratings are middling. Owners who get the fit right praise the comfort for side sleeping and the drop in snoring noise. Complaints center on fit and on how much sound actually gets through.
These reusable sleeping earplugs have an oval shape that follows the natural shape of the ear canal. They are made from a very soft thermoplastic material called AlpineThermoShape, which shapes itself to the ear canal and stays in place all night. The soft material suits side sleepers.
Each earplug contains Alpine noise reduction gel and has an average attenuation (SNR) of 27 dB. Disturbing sounds, including snoring, are muffled. The material is hypoallergenic and silicone free.
The earplugs can be reused up to 100 times, depending on how often they are used. To clean them, use lukewarm water and soap. Keeping them clean extends their lifespan. They come with a pocket-sized travel case.
