How to Get the Perfect Fit: Your Guide to Spares’ Interchangeable Ear Cups
No two ears are the same. That’s why Spares include four different ear cup sizes in every package - so you get a fit that’s not only secure, but comfortable enough to wear all day, whether you're working, riding, performing, or traveling.
But choosing the right fit isn’t just about comfort - it’s critical to getting full hearing protection and crystal-clear sound.
Here’s how to get it right.
Why Fit Matters
Spares are designed to create a soft seal at the opening of the ear canal. This seal is what allows the precision mesh filter to work properly - reducing dangerous frequencies while preserving clarity.
A poor fit means:
- Reduced effectiveness
- Sound leakage or muffling
- Discomfort or slippage
- Less protection for your hearing
When Spares are seated properly, you'll feel a gentle hold - no pressure, no pain, no popping - just a clean, natural reduction in harmful volume.
The Four Sizes Explained
Every Spares set includes four interchangeable silicone ear cups:
- Small: For smaller ear canals or those who prefer a softer, looser fit
- Medium: A balanced fit - works best for the majority of users
- Large: The pre-installed size, great for average to fuller ears
- Extra Large: For those who need a tighter, more secure hold
All cups are soft, flexible, and designed to contour comfortably to the shape of your ear.
Fit Tips & Tricks
- Feel pressure? Try a smaller size. You want comfort, not compression.
- Feel movement or looseness? Size up until it feels gently secure.
- Muffled sound? Try backing them out slightly - don’t push them deep.
- Switch sizes for each ear. It’s more common than you think. Most people’s ears aren’t exactly symmetrical.
How to Insert Spares Correctly
- Gently seat the earplug at the entrance of your ear canal - don’t push it inside.
- Let the silicone form a natural seal. It should sit flush, without sticking out or needing force.
- Do a sound check. You’ll know you’ve got the right fit when sound becomes softer - but still sharp and clear.
Built to Stay Put
Once you’ve found your size, Spares are designed to stay locked in - even during movement, sweat, long wear, or under helmets and hats.
No stems. No awkward loops. Just a clean, low-profile fit that works for real life.
Your Ears, Your Fit
Everyone’s ears are different - and that’s exactly why we include multiple sizes in every set. Finding your perfect fit isn’t a luxury - it’s a necessity.
