BQEYZ Spring 1 IEM

In the new Spring 1 IEM from BQEYZ, there’s a lot to be excited about. Diving right into the drivers, each earphone gets three: a 13-millimeter dynamic driver for bass frequencies, a 7-layer piezoelectric driver for ultra-high frequencies, and BQEYZ’s own custom balanced armature for mid to high frequencies. To maximize the potential of each driver, the Spring 1 has the world’s first unibody design that includes both dynamic and ceramic components in one space-efficient unit. With a lightweight aluminum housing and a detachable silver-coated 8-core cable, the Spring 1 optimizes both strength and signal transmission alongside sound quality. Giving it an 8.8/10 score, About Audio calls the Spring 1 a “rock-solid choice in [the] long-term … that thoroughly lives up to the expectations.”
