Why it matters
Why change ear tips and wax caps
Ear tips sit in your ear all day, so they wear out. A worn tip stops sealing well, and a loose seal is the main cause of whistling.
Wax caps sit over the sound outlet and catch wax and debris. Changing them keeps wax out and the sound clear.
- Clearer sound
- A snug, comfortable fit
- Less whistling from a loose seal

Is this a subscription?
No. It is a one-time purchase. You pay once and get a full year of tips, wax caps and cleaning tools.
When should I change an ear tip?
Change a tip when it looks worn or dirty, or when the fit feels loose. Whistling usually means the tip is not sealing.
