Know before you buy
The 5th-generation DMT driver is designed for a balanced and accurate sound profile. It prioritizes clarity and detail, making it well-suited for listeners who prefer a natural, faithful reproduction of their music rather than an overly colored or bass-heavy sound.
With an impedance of 32Ω and a sensitivity of 114dB/Vrms, these IEMs are quite efficient. They can be driven easily by most smartphones, tablets, or standard laptop headphone jacks without requiring a dedicated external amplifier.
The passive noise isolation relies on the physical seal created by the in-ear fit. When paired with the correct size ear tips, it effectively blocks out a significant amount of ambient background noise, allowing you to focus on your music in environments like offices or commutes.
Yes, the Fission is engineered with an ergonomic in-ear design intended for extended wear. The lightweight construction and secure fit help minimize ear fatigue, though comfort can vary depending on your individual ear shape and the tip size used.
