Nocturnal noise raises cortisol even when you don’t wake up. ~27dB reduction, reusable, medical-grade silicone — no foam, no latex, no wax.. Medical-grade silicone, no foam, no PVC, no phthalates. Reusable for months.. Made from Medical-Grade Silicone. Free from Foam (polyurethane), Latex, PVC (polyvinyl chloride), Wax, Phthalate plasticizers (DEHP / DINP). Noise during sleep increases cortisol production even when it doesn’t fully wake you. Studies show that reducing nighttime noise exposure by as little as 10dB improves sleep quality and reduces morning stress hormone levels. 1 verified customer reviews, 5/5 average. $9.00 — ships internationally from the UK.

The Silicone Ear Plugs is made from Medical-Grade Silicone.
Body
Hypoallergenic, non-porous, flexible. No latex, no PVC, no phthalates. The same silicone used in medical devices.
Noise during sleep increases cortisol production even when it doesn’t fully wake you. Studies show that reducing nighttime noise exposure by as little as 10dB improves sleep quality and reduces morning stress hormone levels.
The Silicone Ear Plugs is free from Foam (polyurethane), Latex, PVC (polyvinyl chloride) and Wax and 2 other substances. Each exclusion is explained below with the reason.
Foam (polyurethane)
Foam ear plugs are single-use and harbour bacteria within hours. Even foam plugs marketed as ‘reusable’ degrade after a few washes because the open-cell structure traps moisture and can’t be sterilised. They expand inside the ear canal, applying outward pressure. Silicone is washable, reusable for months, and sits at the canal opening without internal expansion.
Latex
Latex is one of the most common contact allergens. Repeated exposure increases sensitisation risk. Medical-grade silicone is hypoallergenic and non-sensitising — the same material used in implants and medical devices.
PVC (polyvinyl chloride)
Cheap ear plugs use PVC softened with phthalate plasticizers. Phthalates are endocrine disruptors that leach from PVC with body heat and moisture — exactly the conditions inside an ear canal.
Wax
Wax ear plugs melt at body temperature, leave residue in the ear canal, and are single-use. Silicone holds its shape at body temperature and cleans with soap and water.
Phthalate plasticizers (DEHP / DINP)
Used to soften PVC and some foam formulations. Phthalates interfere with hormone signalling. Not present in medical-grade silicone.
Antimicrobial chemical treatments
Some ear plugs add triclosan or silver nanoparticles to combat the bacterial growth their own foam material encourages. Silicone is non-porous — bacteria can’t colonise the surface, so no antimicrobial additives are needed.

Pick the right size
Try both sizes if included. The plug should sit snugly at the opening of your ear canal without being forced in.
Insert gently
Push the plug into your ear canal. Don’t force it deep — it should sit at the opening and create a seal by contact.
Check the seal
You should feel the noise drop immediately. If sound is still getting through, adjust the position or try the other size.
Clean after each use
Warm water, mild soap. Air dry. They’ll last months with daily use.
Getting the fit right
You’ll need a couple of nights to find the right depth. Too deep is uncomfortable, too shallow and they fall out. The sweet spot is at the opening of the ear canal, pressed gently to seal. Most people get it by night 2–3.
Noticing the difference
Partner snoring, street noise, early bin lorries — still audible but muted. You’ll sleep through things that used to wake you. Your alarm still comes through clearly.
Part of the routine
Inserting them takes a few seconds. They feel normal. The silicone holds up after months of daily use — wash them weekly, replace when they lose tackiness or don’t seal as well (typically 3–6 months).
Material matters most. Foam plugs are single-use, harbour bacteria, and expand inside the ear canal. Wax melts at body temperature. Silicone is reusable, washable, hypoallergenic, and sits flush at the canal opening. ~27dB reduction brings most bedroom environments below the 30dB threshold where sleep disruption begins (Basner et al., 2014).
Yes. Nocturnal noise increases cortisol and disrupts sleep stages even when you don’t consciously wake (Hume et al., 2012). Subjective sleep quality deteriorates above 32dB (Öhrström & Rylander, 1990). Ear plugs bringing ambient noise below threshold let your body stay in deep and REM sleep instead of cycling to lighter stages.
Yes. ~27dB reduction means sounds are quieter, not gone. Alarms, fire alarms, and doorbells remain audible. This is a safety feature, not a limitation.
Silicone is soft and sits flush with the ear — nothing sticks out. Much more comfortable than rigid foam plugs that dig in under pillow pressure.
Foam: single-use, expands inside the canal, can’t be sterilised, harbours bacteria within hours. Wax: melts at body temperature, leaves residue, single-use. Silicone: reusable for months, washable, non-porous, hypoallergenic. Medical-grade silicone is the same material used in medical implants.
Warm water and mild soap after each use. Air dry. They’re reusable for months with daily use.
Approximately 27dB NRR. That’s enough to bring most urban bedrooms below the 30dB threshold where sleep disruption begins, while keeping safety-critical sounds audible.
Yes. Silicone creates a watertight seal at the ear canal opening. Also works for focus work, travel, concerts, and any environment where you want noise reduction without full isolation.

Hume et al. (2012)
Noise & Health
Nocturnal noise exposure increases arousals and shifts sleep to lighter stages, even when subjects don’t consciously wake
Basner et al. (2014)
The Lancet
Environmental noise is a significant public health concern — cardiovascular risk increases with chronic nighttime noise above 40dB
Öhrström E, Rylander R (1990)
Archives of Environmental Health
Subjective sleep quality deteriorated measurably at night-time noise exposures above 32 dB(A). Participants reported increased fatigue, reduced morning alertness, and more frequent awakenings. Even subjects who reported no conscious waking showed elevated cortisol the next morning — the autonomic system reacts to noise even when the conscious mind does not.
Light, Sleep, and Melatonin
Noise is one disruptor; light is the other. Melatonin suppression begins at 1.3 lux (Zeitzer et al., 2000) — addressing both is how sleep quality compounds.
Phthalates: Why Soft Plastic Feels Soft
Cheap PVC ear plugs are softened with DEHP or DINP. Both leach with body heat and moisture — exactly the conditions inside an ear canal for 8 hours.
Endocrine Disruptors: The Mechanism
Phthalates aren't a single chemical — they're a class. Why 'PVC-free' doesn't mean 'plasticiser-free' unless the alternative material is named.
Fragrance: 3,000+ Substances on a One-Word Label
Some 'comfort coated' ear plugs carry mild fragrance to mask plasticiser odour. The same regulatory loophole on a product that sits in the ear canal nightly.

These are ear plugs for noise reduction, not industrial hearing protection. Discontinue use if you feel pain or discomfort.
