ZQuiet vs Somnofit-S

Both of these hold your lower jaw slightly forward to keep your airway more open, which makes them suitable for people whose snoring starts in the jaw or mouth. Beyond that, they take quite different approaches.

ZQuiet keeps things simple. It's a soft, hinged device with no moulding, and it comes with two sizes so you can begin with less advancement and step up. It's an easy, relatively low-cost way to find out whether a mouthpiece suits you at all.

Somnofit-S focuses on comfort and size. It's a compact, adjustable device designed to feel noticeably smaller in the mouth than most mouthpieces, and you can change how far forward your jaw sits. That makes it appealing to people who have found other mouthpieces too bulky to sleep with. It sits at the premium end on price.

If you've never used a mouthpiece, it often makes sense to start with the simpler, cheaper option and only move to a premium device if you know jaw advancement helps but comfort was the problem. If you've already tried a bulky mouthpiece and given up on it, a smaller adjustable design is worth considering.

With either device, give yourself a week or two to adjust, expect some jaw soreness at first, and check with a dentist beforehand if you have dental work or jaw problems. Neither is a substitute for seeing a doctor if you have signs of sleep apnea.
