KZ CCA DUO Earbuds with microphone

At the heart of the DUO lies its impeccable professional acoustic signature, made possible by its 7mm + 7mm dual-dynamic driver configuration. Unlike conventional 10mm dynamic drivers, this powerful combination brings forth finer resolution and richer sound details. With each driver independently designed to play a different role, the DUO ensures a harmonious blend of punchy lows and crystal-clear mids and highs.

What are the advantages of DUO accoustic design compared to other products?
DUO built-in 7mm+7mm custom dual magnetic circuit and dual-cavity 2DD driver, which has double the magnetic flux and powerful resolution compared to single magnetic single-cavity IEM. It provides all-around and robust improvement in sound quality details. Not only can you experience powerful bass, but also clear, natural mid and treble. However, the single magnetic single-cavity IEM is pale in tone.
