Know before you buy
ADEL™ technology is designed to reduce pneumatic pressure in the ear canal. This helps prevent listener fatigue during long sessions and allows for a more natural, open soundstage while maintaining high-fidelity audio.
Yes, the Zen 4 provides up to 26dB of passive noise isolation. This level of attenuation is effective for blocking out ambient stage noise, allowing you to monitor your mix clearly at lower, safer volumes.
The Zen 4 comes with multiple ear tip options to accommodate different ear canal sizes. Because the shell is 3D-printed with an ergonomic shape, finding the right tip size will provide a secure seal and consistent bass response.
Yes, these monitors feature a detachable high-fidelity cable. This allows you to easily replace the cable if it wears out or upgrade to a different cable type without needing to replace the entire monitor unit.
The quad-driver configuration uses a dedicated 4-way crossover to separate frequencies across one high, one mid, and two low balanced armatures. This results in a detailed, balanced sound with punchy bass and clear, lush mids.
The shells are crafted from hypoallergenic acrylic, which is lightweight and gentle on the skin. Combined with the ergonomic design, they are built to remain comfortable even during extended studio or performance sessions.
