The KZ Duet is a wired in-ear earphone with dual dynamic drivers per side, a 3.5 mm plug and an in-line microphone, so one set covers music, calls and meetings. It makes sense as a first IEM or as a backup pair kept in the bag.
Who the KZ Duet is for
First IEM: Two dynamic drivers per side and a 3.5 mm plug make it an easy first step into in-ear monitors.
Calls and meetings: The in-line mic lets you take a call or join a meeting, then get back to the album without swapping earphones.
Laptops, dongles and older phones: The 3.5 mm plug goes straight into a laptop, a dongle or an older phone.
Backup pair for the bag: It's a practical spare to keep packed for travel.
Skip it if: Your only source is a phone without a headphone jack and you'd rather not add a dongle; the Duet ends in a 3.5 mm plug.
