The main difference between ZQuiet and VitalSleep is how each one gets its fit. One comes ready to wear, and the other is molded and then adjusted. That choice affects cost, comfort and how much trial and error you face. Prices and stock are as of October 2026.
The Ready-to-Wear Route: ZQuiet
ZQuiet comes in sizes, and you choose the one that sits best. Its kits ran about $39.95, $59.95 and $89.95. A 60-night trial is listed on the product page.
See our ZQuiet review for the full rundown.
The Mold-and-Adjust Route: VitalSleep
VitalSleep is softened in hot water and bitten into shape. A small tool then moves the lower jaw forward in 1 mm steps, from 0 to 8 mm. It lists at about $119.95 with a 60-night trial and a one-year warranty.
The men’s size showed as sold out. Check the page for stock.
Which Fit Method Suits You?
- Pick ZQuiet if you want the lowest cost and no hot water.
- Pick VitalSleep if you want to fine-tune how far the jaw moves.
- Pick neither if you gasp at night, since sleep apnea needs a doctor.
Fit Matters More Than Brand
A device that sits too far forward can leave your jaw sore. One that sits too far back may not help. A systematic review of mandibular advancement devices discusses their use for snoring and sleep apnea.
