Innovative Snoring Solution : DIFINEY Advanced 4.0 gently advances your lower jaw to help create more space through the airway, improve airflow, and reduce snoring. With a design patent application filed, its patent-pending design brings a more advanced and customizable approach to nightly snore reduction.

Targets the Mechanics Behind Snoring : Rather than simply working around the noise, DIFINEY Advanced 4.0 supports the lower jaw in a slightly more forward position while you sleep. This helps create more space behind the tongue and soft palate, reducing the soft-tissue vibration that contributes to snoring.

FDA Cleared & BPA Free : DIFINEY Advanced 4.0 is FDA cleared and made with BPA-free materials, giving you added confidence in the quality and safety of the anti-snoring device you use each night.

Fully Customizable : Custom-fit the mouthpiece to your bite at home, then fine-tune the lower-jaw advancement from 1–6 mm . Its fully adjustable design gives you greater control over fit and positioning, helping create a comfortable setup tailored to your needs and improve sleep quality for all users.

Easy to Use : Simply fit the mouthpiece at home and wear DIFINEY Advanced 4.0 before sleep for instant relief from snoring . No masks, uncomfortable straps, bulky machines, or complicated setup — just a straightforward addition to your nightly routine.

Guarantee by Bundle : Give yourself time to find the fit and adjustment that works best for you. Your guarantee depends on the bundle you choose: 1 device — 30 days; 2 devices — 90 days; 3 devices — 120 days. Try DIFINEY Advanced 4.0 for the guarantee period included with your selected bundle and decide if it’s right for your routine.
