Know before you buy
ADEL technology uses a secondary membrane to absorb pneumatic pressure in the ear canal. This reduces listener fatigue and creates a more spacious, natural soundstage compared to traditional sealed monitors.
The Zen 4 provides up to 26dB of passive noise isolation. By creating a tight seal with the included tips, they effectively block out ambient background noise without needing active electronic cancellation.
Yes, the Zen 4 uses a standard 2-pin connector. This makes the cable easily detachable and replaceable if you need a different length or want to experiment with aftermarket cables.
The 4-way crossover system splits the audio signal between two dedicated low-frequency drivers and two high/mid-frequency drivers. This configuration ensures that bass, mids, and highs are reproduced with greater clarity and less distortion than a single-driver setup.
The Zen 4 features a universal fit design and comes with a variety of replaceable tips. You can experiment with different sizes and materials to find the most secure and comfortable seal for your specific ear shape.
With an impedance of 28 ohms, the Zen 4 is efficient enough to be driven directly by most smartphones, tablets, or laptops equipped with a 3.5mm jack. While a dedicated DAC or amp can improve audio fidelity, it is not strictly required.
