SpinFit CP240 Double Flange Eartips (S) – Replacement for 4.5-5mm Nozzles or 3-3.5mm with Insert

Overview

SpinFit CP240 Double Flange eartips offer a versatile, comfortable replacement option for a wide range of earphones. Crafted from soft, patented silicone, these tips are designed to feel gentle against the outer ear while helping maintain a stable, secure fit during daily listening and light activity. This model is sized for two nozzle options: 4.5–5 mm without an insert, and 3–3.5 mm with the included insert.

Why this design stands out

The CP240 uses a dual-flange silhouette that aims to balance a snug seal with long-wear comfort. The soft silicone surface is smooth to the touch, helping reduce discomfort during longer listening sessions. The insert provides an adjustable option for slightly smaller nozzles, expanding compatibility across many earphone families without sacrificing the core fit you expect from SpinFit.
