The minimalist metal look of the AM13 earphones infuses technology with fashion. The comfortable, ergonomic design of the earphones includes an innovative feature that allows the user to switch between normal and bass modes by twisting the rubber sleeve. The composite diaphragm allows for a broader acoustic field and bandwidth, and the optimized sound chamber design and added inner sound chambers effectively reduce sound distortion from vibration. Each earphone features an asymmetric design, splicing together geometric shapes for a sleek, futuristic look. The earphones diverge from conventional design by breaking up the cylindrical body.
