THE PROBLEM

Their snoring.Your lost sleep.

Snoring is often dismissed as an inconvenience. For the person beside it, the real cost is what the sound takes away: uninterrupted sleep.

68%

of surveyed US adults with a bed partner said that partner snores. [3]

62 min

of additional sleep per night was the estimated equivalent for partners after snoring and obstructive breathing were eliminated in a small overnight study. [4]

Nightly noise becomes cumulative sleep loss.

One bad night is an annoyance. Night after night, partner snoring can turn repeated interruptions into a pattern of insufficient sleep. The concern is not the sound itself. It is the sleep you keep missing.

This is where the consequences begin.

Chronic short sleep is linked to obesity, diabetes, high blood pressure, heart disease, stroke, anxiety and depression. [5] In one long-term cohort, people sleeping six hours or less in midlife were 30% more likely to later develop dementia. [6]

Undertone is designed to break that chain. Reduce the disruptive sound at your ears, without asking either partner to leave the bed.

THE SOLUTION

One recording at home.
One fitting appointment.

  1. 01

    Record three nights

    Record on your phone at home. We identify the frequencies that recur in your partner’s snoring, from low rumbles to sharper sounds.

  2. 02

    Get your ears fitted

    A hearing professional checks your ears and takes an impression or scan. We include the appointment in the price. [1]

  3. 03

    We make your earplugs

    Your ear shape sets the fit. Your partner’s recordings guide the sound configuration. We bring them together in soft, low-profile earplugs made for sleep.

Before you sign up.

Why match the snoring?

A low rumble and a sharp rasp put different demands on an earplug. Published research shows that snores vary in their frequency patterns. [2] Undertone uses your recordings to guide the choice of configuration, giving the sound that bothers you a say in the design. The research supports that rationale; Undertone’s matching benefit is still being tested.

Will they block all snoring?

No. Passive earplugs reduce sound; they do not remove it completely. How much you hear depends on the sound, the fit and how the plugs sit while you sleep.

Why a professional fitting?

A good fit starts with your actual ears. A professional checks the ear canal and captures its shape for your pair. That examination and impression process is described in British Society of Audiology guidance. [1] A current impression may also make ordering your next pair easier.

Can I upgrade from Select to Signature using the same fitting?

Yes, we’ll happily accommodate an upgrade. If your saved impression or scan is still suitable, we can use it to make your Signature pair without another fitting appointment. We’ll check your fit file before making the new pair.

Are these a treatment for sleep apnea?

No. Undertone is for the listening partner’s comfort. Earplugs do not treat sleep apnea or replace prescribed treatment.

What happens after I join?

You’ll get launch and fitting updates from Undertone. Choose the pair you’re interested in and tell us your city so we can plan clinic access. No payment, no commitment.

The research behind the approach
  1. British Society of Audiology: Taking an aural impression (2023). Describes professional ear examination, impressions and digital scanning. Supports the fitting procedure; does not test Undertone.
  2. Scientific Reports (2016): Snoring Sounds Predict Obstruction Sites and Surgical Response. Reports differing snore frequency patterns across low, middle and high bands. Supports studying the sound profile; does not establish an advantage for recording-matched earplugs.
  3. American Academy of Sleep Medicine: Bed Partners Who Snore survey (2021). Of 1,277 US respondents with a bed partner, 68% reported that their partner snores. The survey did not measure Undertone or sleep disruption.
  4. Mayo Clinic Proceedings: The effect of snoring and obstructive sleep apnea on bed partners (1999). In a one-night study of 10 couples, eliminating snoring and obstructive breathing improved partners’ median sleep efficiency from 74% to 87%. The authors calculated that difference as 62 additional minutes of sleep across an eight-hour night. This is not an earplug study.
  5. CDC: Short sleep duration among adults. Recommends at least seven hours for adults and reports associations between regular short sleep and obesity, diabetes, hypertension, heart disease, stroke, anxiety and depression. It does not attribute those conditions specifically to partner snoring.
  6. NIH Research Matters: Lack of sleep in middle age may increase dementia risk (2021). Summarizes a nearly 8,000-person cohort in which six hours or less of sleep in the 50s and 60s was associated with a 30% higher rate of later dementia diagnosis. The observational study does not establish causation.
  7. US Census Bureau: Population by Age, 2024 ACS 1-Year Supplemental Estimates. The 25 to 34, 35 to 44, 45 to 54 and 55 to 64 cohorts total 174,988,670 people. The model rounds this to 175.0 million.
  8. American Academy of Sleep Medicine: 2021 Sleep Prioritization Survey. Of 2,006 US adults surveyed, 1,277, or 64%, reported having a bed partner. The model uses this direct measure instead of estimating relationships and bed-sharing separately.
  9. Journal of Personalized Medicine: The Potential Effect of Changing Patient Position on Snoring, systematic review (2024). The review describes estimates that approximately 25% of adults snore regularly. The model applies that general adult estimate to adults with bed partners.
