Find Your Best Fit
It's all about the fit!
Fluid™ comes in two sizes: Small and Large. The right size creates a secure seal while staying comfortable, even during extended wear.
Too small, and the tip may not inflate enough to seal your ear canal effectively. Too large, and it can create unnecessary pressure, leading to discomfort over time.
Because ear canals come in all shapes and sizes, and you can't judge their size just by looking from the outside, finding the size for your best fit isn't always obvious.
The Fit Pack: try both, let your ears decide
That's why we created the Fluid™ Fit Pack for first time buyers. With both Small and Large included — and 25% off for first-time buyers, applied automatically at checkout — you can try each size and discover which feels and fits best. Wear each for a day or two; the size that seals easily and stays comfortable is your best fit. You keep both pairs — some people can wear both and a spare is always useful — or you may know someone who finds the other size a perfect fit, they will love you for it!
Our General Guide to Finding Your Best Fit
We always recommend trying both sizes to discover which feels and fits best. That's why we offer our biggest savings with the Fluid™ Fit Pack, which includes both Large and Small.
If you'd prefer to start with just one size, we generally recommend Large, unless you already know you have smaller ear canals.
- Large: Designed to provide a secure, comfortable fit for most people. It's our recommended starting point.
- Small: Designed specifically for people who find the Large size uncomfortable.
Remember, the best fit is one that creates a secure, reliable seal without uncomfortable pressure. Because everyone's ears are different, trying both sizes is the surest way to find your best fit.
