How do in-ear monitors work for singers?

Updated October 2026 · How we answer

What they do

In-ear monitors, often called IEMs, replace or supplement the floor wedges that point back at performers. A sound engineer sends a custom mix from a monitor board to a wireless or wired pack you wear on your belt. The earpieces fit snugly in your ears and carry your vocal and instrument mix.

Because the sound is delivered close to your ears, you can usually hear yourself more clearly and with less volume on stage. Many singers also find it easier to stay on pitch.

• Custom mix controlled by the monitor engineer
• Earpieces fit in the ear canal
• Wired or wireless packs are both common
• Batteries and interference need checking before each show

Getting comfortable with them

Ask for a mix before the show during soundcheck, and tell the engineer what you need louder or quieter. Small changes make a big difference, so speak up early. Practice in them at home or in rehearsal if you can.

Keep a spare battery and a backup earpiece if the venue provides them. Check the fit before you go on, since a loose earpiece can fall out during movement.
