Quad-Driver IEM With 2 Cables

Magaosi has become a favorite on Massdrop for its in-ear monitors. Ergonomically designed and packaged with a variety of accessories, they provide a great value in sound. The MGS-401 is no different. Built with four balanced-armature drivers (one low frequency, one medium, and two high), it aims for a large soundstage with extended highs and balance throughout. Like previous Magaosi offerings, this one comes with a pair of cables. Audiophiles carrying a high-end digital music player are sure to appreciate the option of a balanced cable: rare with IEMs of this price. Finally, the swirled colorways are sure to stand out in a crowd.

Note: At checkout, you'll have your choice of colorway—jade or black/white—and cable set. Choose the 3.5mm cable and 2.5mm balanced cable (base price) or the 3.5mm cable and Bluetooth cable (+ $10).
