An ear monitor is a small earphone that sits inside the ear and plays a mix for the wearer. Musicians use ear monitors on stage to hear themselves and the band without floor wedges, and listeners use them for private listening.
What an ear monitor is
An ear monitor is an in-ear earphone built to sit in the ear canal and deliver sound straight to the ear. It has a driver or a set of drivers inside a shell shaped to the ear, and a cable that runs to the audio source. The sealed fit is the point: outside sound stays out, and the sound from the monitor stays in.
How it differs from earbuds
Ordinary earbuds rest in the outer ear and let outside sound in, while an ear monitor seals the canal with a tip that fits inside it. The seal gives the monitor its isolation, since sound has nowhere to leak. Earbuds suit casual listening; ear monitors suit hearing a mix on stage.
Wired or wireless
Ear monitors connect by cable to a receiver, a mixer or a headphone output, and the cable is detachable on some models. Wireless ear monitor systems add a bodypack receiver that the earphones plug into, so the wearer can move without a cable to the mixer. A wired connection suits listening at a desk or in a studio, while a wireless system suits a stage.
How to fit an ear monitor
Pick the eartip size that seals the canal without pressure, then push the earphone in gently and twist it until the seal holds. Run the cable over the ear and down the back so it stays out of the way. If one side is quieter than the other, refit the tip or try another size before you change anything else.
What to look for when choosing
Check the driver setup, the impedance and whether the cable detaches, since those decide what the ear monitor needs to drive it and how it can be repaired. Try the fit with the eartips supplied, and check that the plug matches the jack on the device you will use. A sealed fit matters more than the number of drivers.

Frequently asked questions
Are ear monitors the same as earbuds?
No. Earbuds rest in the outer ear, while an ear monitor seals the ear canal with a tip that fits inside it.
Do ear monitors need an amplifier?
Some do and some do not, since it depends on the impedance and sensitivity of the model. Low-impedance models run from a phone or laptop jack, while higher-impedance models need more power from a headphone output or amplifier.
Can I use ear monitors for everyday listening?
Yes. Pick a model with a plug that matches the device you use and a cable length that reaches it.
How do I keep ear monitors clean?
Wipe the shells with a soft dry cloth after use and keep the eartips free of wax and dirt. Remove the eartips to clean them, let them dry fully, and store the ear monitors in a case so the cable does not tangle.
