The ZSN X In-ear Earphone is a 3.5mm wired earphone with an ear hook design for long-term wear comfort. It features a 1BA+1DD drive that delivers dynamic bass and high sensitivity treble. Boasting a durable combination of metal and resin, the earphones have an exquisite appearance with coexisting metal texture and fashionable streamline aesthetics. The earphone uses 4 strands of 100 core high-quality silver plated wire, and double 0.75mm gold-plated pins for a soft, smooth, tangle-free detachable cable. The 3.5mm gold-plated plug combats oxidation and reduces signal loss, providing better audio transmission for almost all 3.5mm audio devices. The headphones come in Black or Gold and include the options of having a mic. Each package contains one pair of ZSN X Wired Headphones, one user manual, and three pairs of earmuffs in varied sizes (S/M/L) to ensure the best fit for all users.
