The KZ ZSN Pro is a crowd-favorite budget IEM that blends clarity and punch. Its hybrid 1DD + 1BA setup delivers powerful bass from the 10 mm dynamic driver with crisp treble from the customized 30095 BA, tuned through a professional electronic crossover for better separation. The detachable 0.75 mm 2-pin system lets you swap/upgrade cables, while the 3.5 mm plug keeps it plug-and-play with phones, laptops, and DACs. A lightweight zinc-alloy + resin build offers a secure, over-ear fit with solid passive isolation—great for music, gaming, and calls. Choose with-mic if you need one-button control and clear voice pickup.
