Customised in-ear Monitors

 Silicon moulds made from ear impressions for the customization of in-ear monitors.

In-ear monitors usually have a universal-type one-size-fits-all rubberized or sponge-like tip that fits into the ear canal.
The universal tips can be uncomfortable for some ears – even the slightest expansion of the sponge can cause some pain in the ear canal with prolonged use.
In-ear monitors can be quite bulky, especially if they have 2 or 3 drivers which make them quite top-heavy. Thus with head movement they will sometimes dislodge from the ear canal and/or fall out of the ear.
The high-density silicone mould is integrated with the in-ear monitor's shape and form to ensure that there is much better retention of the monitor in the ear. The mould can be made right into the top tip (helix) of the ear which ensures a tight, snug fit with excellent retention and lack of movement within the ear.
The mould also acts as an ambient noise suppressor, thus increasing the signal-to-noise ratio.
Musicians will have the advantage of not being overwhelmed by other on-stage instruments.
There is also a bottom-end frequency enhancement, giving a richer and fuller sound at a lower volume setting.
Popular in-ear monitors which are often fit-customized are Shure, Sennheiser, Skullkandy, Sony, etc..
