KZ ASX With Mic: a wired in-ear monitor built around passive noise isolation, for planes, trains and open-plan offices. This is the version with an in-line mic on the cable, so the same pair covers calls as well as music, and it runs fine straight from a dongle DAC or a portable player.
Who the KZ ASX With Mic is for
Travelers: On planes and trains, passive isolation from a good seal is what keeps outside noise down.
Open-plan office workers: In a noisy room, a good seal does more for perceived detail than any amount of extra driver count.
Dongle DAC and portable player users: It works fine plugged straight into a dongle DAC or a portable player.
Listeners willing to dial in the fit: Try the included tip sizes until the seal is airtight before judging the bass; an under-sealed IEM sounds thin.
Callers: The in-line mic on the cable means calls don't need a second pair of earphones.
Skip it if: you only listen to music and prefer a plain cable; the no-mic KZ ASX is the same earphone without the in-line mic.
