KZ ASX: a wired in-ear monitor built around passive noise isolation, for planes, trains and open-plan offices. This is the no-mic version, and it runs fine straight from a dongle DAC or a portable player.

Who the KZ ASX 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.
  • Skip it if: you also take calls on your earphones; this ASX is the version without a microphone.

KZ ASX key specs

  • Connection: Wired
  • Noise control: Passive noise isolation
  • Microphone: None (no-mic version)

KZ ASX vs similar options

  • vs SIMGOT EA500 DSP: Plugs straight into USB-C, with built-in DSP handling the conversion and a mic for calls; stay with the ASX if you'll listen through a dongle DAC or portable player and don't need a mic.
