IEMs for gaming: turn your in-ear monitors into a headset

In-ear monitors make a light, comfortable gaming headset: they block out the room, and a wired cable adds no Bluetooth delay. Swap your IEM cable for one with a microphone. Ethos MKIII Pro-Gaming has a recording-grade microphone and a 3.5 mm headset plug, from USD 89, and a microphone option is offered on selected configurable cables. Every cable is handmade to order in Singapore and ships worldwide with FedEx.

Questions

Common questions

Are IEMs good for gaming?

Yes. They’re lighter than a headset, seal out room noise, and on a wired cable there is no Bluetooth delay, so footsteps and voice chat stay in sync.

Will a mic cable fit my IEMs?

It needs to match your IEM’s connector, such as 2-pin or MMCX. Check yours with Find my IEM, then ask us which connectors Ethos MKIII Pro-Gaming is offered with.

Can I get a mic with a 4.4 mm balanced plug?

No. A 4.4 mm plug uses all of its contacts for audio, so a microphone needs a 3.5 mm headset plug. For other plugs, ask us.
