Know before you buy
The W1 eartips are designed for earphones with a nozzle diameter between 5mm and 6mm. If your current earphones use the CP145 model or fall within this nozzle size range, they will be compatible.
The W-shaped design is engineered to minimize ear canal pressure while creating a more robust seal. This shape is particularly effective at maintaining stability for larger or multi-driver earphones that might otherwise feel heavy or loose.
Yes, the W1 eartips are made from medical-grade silicone. This material is specifically chosen to be hypoallergenic and reduce the risk of allergic reactions during extended listening sessions.
The core uses a combination of soft outer silicone for comfort and firmer inner silicone for structural integrity. This dual-layer approach ensures the eartip stays securely attached to the nozzle while providing a flexible, comfortable fit inside your ear.
By providing a more reliable and consistent seal, the W1 eartips can significantly improve noise isolation and bass response. A better seal ensures that less sound escapes, allowing your drivers to perform at their full potential.
