Serapis QuietShell on Kickstarter: Press-to-Seal Sleep Earplugs in a White Noise Shell
Earplugs fix half of a loud night. The hum of traffic fades, then a door closes down the hall and you are awake again, listening. A white noise machine covers sound without lowering it. The Serapis QuietShell puts both answers on one nightstand: sleep earplugs that seal against outside noise, stored in a bedside shell that plays sounds to soften whatever slips past them.
Serapis returns to Kickstarter with a delivered record: its first campaign, an all-in-one sleep aid, closed in January 2026 at 4,099% of its goal and is marked as fulfilled. The Serapis QuietShell price on Kickstarter is $47 for backers who place a $1 VIP reservation.

Quick Verdict
Our verdict: 8.6/10
Who Is It For?
It suits light sleepers whose bedrooms face traffic or a humming vent, and who already rely on sleep earplugs to get through the night. Side sleepers fit the profile too, as do people who often sleep away from home, since the earplugs travel inside their case.
Main Strengths
Earplugs cut outside noise at the ear while the shell plays sleep sounds into the room, so steady noise and sudden noise each get their own answer.
The Press-to-Seal cap lets you tighten the fit once the earplug is in, instead of pushing it deeper into the ear.
UV care starts by itself when you close the lid on the stored earplugs, with no separate device to buy.
The earplugs carry no battery, Bluetooth or charging port, so only the shell ever goes on a cable.
Beyond its built-in sounds, the shell works as a Bluetooth 5.4 speaker with a 30, 60 or 90-minute sleep timer.
Main Limitations
The earplugs are passive, with no active noise cancellation, so how much noise they block depends on the fit you get from the tips.
UV care adds a step rather than replacing one: the tips still need rinsing and drying by hand.
Delivery is estimated for June 2027, with tooling, pilot production and compliance testing still to come after the campaign.
Is the Serapis QuietShell Worth Backing?
Yes, for light sleepers whose nights are broken by traffic and household noise. Anyone who needs active noise cancellation or audio played inside the ear should pass. The decisive reason is the pairing of a sealing earplug with masking in the room, in one shell: the Serapis QuietShell campaign.
Serapis QuietShell Price on Kickstarter
The Serapis QuietShell price on Kickstarter is $47 for backers who place a $1 VIP reservation, against a $99 MSRP. Among the public tiers, the Early Bird is $59, limited to 300 units, and the Kickstarter Special is $68. The Kickstarter Special is the tier to judge the campaign by: as the only single-unit reward without a limit, it is the price every backer can count on, for the full box.
At $68, the Kickstarter Special sits 31% under retail for the complete set, and the VIP route saves $20 on the same box, reservation included. Beyond the box, the earplugs are reusable and the only parts made to be replaced are the ear tips, whose price Serapis has not published. That makes the Kickstarter Special a fair price, and the VIP reservation the better deal for anyone who holds one: the Serapis QuietShell offer.
What Is the Serapis QuietShell and What Problem Does It Solve?
Serapis QuietShell: Passive Press-to-Seal Earplugs Stored in a Speaker and UV Shell
The Serapis QuietShell is a small bedside shell built around one pair of earplugs. Between nights it is their case and their UV station; at bedtime it becomes the speaker that plays sleep sounds beside the bed. The earplugs are soft silicone with a flexible outer cap. Serapis calls the result a 3-in-1 sleep system.
The shell is model HT012 and weighs about 100 g. It charges over USB-C, and the box holds the QuietShell, two Press-to-Seal earplugs, six ear tips across XS, S, M and L, and a charging cable. Serapis says its team brings 15 years of sleep product development to the project, and its previous campaign was the Serapis sleep aid we reviewed.
Why Sleeping With Earplugs Became Its Own Problem
Noise at night comes in two shapes. Some of it never stops, like traffic or a ventilation fan, and some arrives without warning: a car passing, a door closing. Earplugs take the edge off the first kind, yet smaller sounds still stand out, and one is enough to interrupt the night. In the morning, reusable earplugs for sleeping need care and a place to stay, and over time they collect earwax, skin oils and moisture.
A sudden sound now lands differently: it arrives muffled, under a soft, steady sound, and feels less abrupt. And the earplugs end the night back in the case they slept beside.
Serapis QuietShell Key Features and Specs: Press-to-Seal Fit, Sleep Sounds, UV Care
Press-to-Seal Earplugs: 35 dB SNR Without Pushing Deeper
The fit takes one extra gesture. You insert the earplug, press its flexible silicone cap and let go. Pressing pushes air out, and the release creates a brief suction effect that helps the soft tip settle into a closer seal. The effect is momentary, not a continuous vacuum, and the goal is a tighter fit without driving the earplug deeper.
The tips are single-layer silicone, and the earplug body keeps a low profile that sits close to the ear. Serapis measured a 35 dB SNR with those tips in a 10-sample test, and notes that actual attenuation depends on fit and conditions.
10 Bedside Sleep Sounds and Bluetooth 5.4: Masking What Gets Through
The sound from the shell works on what the seal lets through. It helps sudden changes in the room feel less prominent; it does not silence them, so the earplugs remain the first line against outside noise.
The shell holds 10 built-in sounds, among them ocean waves, a crackling campfire, birdsong and a gently flowing stream, played through a 4Ω, 5W speaker. The sleep timer and the optional Bluetooth mode, rated at 10 m or more, give the bedside speaker a second use. Serapis has not confirmed the final playback time on a charge.
Built-In UV Care: A Five-Minute Cycle That Starts When the Lid Closes
After use, the earplugs go back into the shell, and closing the lid starts a five-minute UV care cycle on its own. The light sits inside the same case that stores them.
Serapis positions the cycle as an additional hygiene step between regular cleanings and makes no sterilization or germ-kill claim. The campaign page does not give the UV type or wavelength. The earplugs should go in cleaned and fully dried.
Should You Back the Serapis QuietShell on Kickstarter?
The Serapis QuietShell turns reusable sleep earplugs into a complete bedside kit for rooms that never get fully quiet. Picture one shell on the nightstand at home and a second in a travel bag for nights away.
Serapis already has working prototypes of the earplug, white noise, Bluetooth, timer and UV care functions. At $47 for VIP reservation holders, against a $99 MSRP, and with the Kickstarter Special as the recommended tier, the Serapis QuietShell campaign is worth backing for a light sleeper.
FAQ about the Serapis QuietShell on Kickstarter
Does white noise play through the Serapis QuietShell earplugs?
No. The earplugs are passive, with no speakers, batteries or electronics inside, and they reduce noise through their fit and seal. White noise and the other sleep sounds play from the speaker built into the QuietShell bedside case, so this is not one of the earplugs with white noise built into the ear.
Is the Serapis QuietShell a good choice of earplugs for side sleepers?
Yes, the earplugs are designed for side sleeping: their low-profile shape sits close to the ear, helping reduce how much material presses between your ear and the pillow. Serapis notes that comfort and fit still vary from person to person, so choosing the right tip size matters as much as the shape.
Does UV care replace cleaning the Serapis QuietShell earplugs?
No. UV care is an extra step between uses. Remove the silicone ear tips, rinse them with warm water as directed and let them dry completely, then return the earplugs to the shell.
Which ear tip sizes come with the Serapis QuietShell?
The box includes six ear tips across XS, S, M and L. Their widths are 10.6 mm for XS, 11.2 mm for S, 12.4 mm for M and 13.1 mm for L, with an XS height of 8.5 mm. Trying more than one size is how to find the most secure fit.
Are taxes and import duties included in the Serapis QuietShell price?
No. Shipping and taxes are charged on top of the reward price. Applicable taxes depend on your location and on Kickstarter's checkout or post-campaign process, and import duties or customs charges vary by country, so check what is shown for your destination before you pledge.
Can you get a refund after backing the Serapis QuietShell?
Not once the campaign ends, unless a defective reward ships, because pledges go straight into production. Until then, the pledge itself is not charged: payment is taken only if the campaign succeeds.
