Frequently Asked Questions

Q: What earphone nozzle sizes are the SpinFit W1 ear tips compatible with?

A: The SpinFit W1 silicone ear tips are designed for earphones with a nozzle diameter of 5mm to 6mm. They are especially well-suited for multi-driver IEMs and large dynamic driver earphones that benefit from the extra stability of the W-shaped double-layer core design.

Q: What makes the SpinFit W1 double-layer design different from standard ear tips?

A: Unlike single-layer ear tips, the W1 features a dual-silicone construction — a soft outer layer for comfortable, gentle wear and a firmer inner layer that grips the nozzle securely. The W(wave)-shaped tube core also helps reduce pressure on the ear canal and improves passive noise isolation compared to traditional ear tips.

Q: Does this package include all sizes of the SpinFit W1?

A: Yes! This is the complete SpinFit W1 box set — it is the first and only SpinFit package that includes all available sizes in a single purchase, so you can easily find the most comfortable and secure fit for your ears without buying sizes separately.

Q: Are the SpinFit W1 ear tips easy to install and remove?

A: Installation is straightforward — simply stretch the ear tip over the earphone nozzle until secure. Because the W1 is designed with extra grip for enhanced stability, please exercise care and take your time when removing the ear tips to avoid any damage to the nozzle or the ear tip itself.
