Comply Foam Tips offer excellent noise isolation. Actual attenuation depends on earphone design and frequency. The foam's passive noise-reduction technology seals out unwanted ambient sound and funnels pure music directly into the ear canal.
Made from extremely soft polyurethane, these foam tips are designed for long-term, comfortable wear. Being, thirty times softer than the silicone used on ordinary, Comply Foam Tips are extraordinarily comfortable, reducing irritation and fatigue and leaving listeners with clear, crisp sound.
On testing, there was no noticeable reduction in the frequency response when Comply Foam Tips were tested against ordinary silicone tips. (Testing performed using a pure tone frequency sweep from 200Hz-8000Hz)
This is my second purchase of the year. Fits comfortably and creates a seal like in the ear. My only complaint is that the foam tips do not fit properly in Senheiser Momentum IE 2 earbuds. It feels like loose to me. Other than that, great for listening long sessions. Ears never feel sore even after 4 long hours of use.
The comply audio pro is an excellent buy not only because of its superior comfort and sound quality but also these has sweat guards and has an universal fit for most earphones. It can fit earphone compatible with comply tx 100 to tx 400 . And as usual headphone zone service is second to none. Thanks a lot headphone zone!!!!
