In-ear monitors for singers are small earpieces that sit in the ear and play the monitor mix straight to the singer, instead of a floor wedge speaker. The mix carries the singer's own voice and the instruments they need to hear, and each singer can have a different mix.
What the earpiece does
An in-ear monitor is an earpiece that fits in the ear canal and connects by cable to the monitor mix. The singer hears their own voice plus the instruments in the mix, and the mix can differ from what the other singers hear. A floor wedge plays the mix into the room for everyone nearby, while an in-ear monitor plays it only to the singer wearing it.
How the fit works
A sealed fit holds the earpiece in place and keeps the monitor mix in the singer's ear. The BASN Bmaster comes with a selection of silicone and memory eartips, and the BASN MMCX comes with eartips in different sizes, so try the sizes to find the one that seals. A carrying case holds the earphones and the spare tips when they are not in use.
Drivers and impedance
The driver is the part inside the earpiece that turns the signal into sound. The BASN Bmaster has triple drivers, the BASN MMCX has 2DD+1BA triple drivers with two dynamic drivers and one balanced armature, and the CCA CRA PRO and the YINYOO KBEAR Storm each have a dynamic driver. Impedance is the resistance the earpiece presents to the source: the BASN Bmaster is 34 ohm, the BASN MMCX is 18 ohm, the CCA CRA PRO is 23 ohm and the YINYOO KBEAR Storm is 30 ohm.
Cables and connections
The BASN Bmaster uses MMCX connectors that rotate 360 degrees, and its kit includes a 6.3mm adapter for a 1/4-inch jack. All four connect through a 3.5mm jack. The BASN MMCX comes with two detachable cables, one with a microphone, and the BASN Bmaster kit includes an in-line microphone cable.
Set the mix before you sing
Plug the earphones into the monitor output and set the level low before the mix starts. Ask the person running the monitor mix to send your voice first, then add the instruments you need to hear, one at a time. If the mix sounds wrong, change the mix at the mixer, not the fit of the earpiece. Keep the earphones and the spare tips in the carrying case when you are done.
