Custom In-Ear Monitoring

In-ear monitors (IEMS)What are in ear monitors?

The idea is simplicity itself. In ear monitors (IEMs) are a form of custom moulded headphones which are often used by bands and artists whilst performing on stage.

IEMs replace the traditional and feedback-prone floor monitors and side fill loudspeakers with a small wireless device worn by the performer, they deliver the monitor mix directly to the ears, at a volume that can be personally controlled. Crucially they also protect against high levels of ambient noise.

For years musicians and other sound professionals have used custom IEMs for the highest degree of comfort and noise isolation on stage.

Now all MP3 and smart phone users can benefit from the same technology – many IEMs are based on technology developed for hearing aids so accuracy levels are exceptionally high, enhancing small details in music that you didn’t even know existed.



Benefits of IEMs

IEMs offer lots of benefits to the performer as well as the audience:

  • Complete freedom of movThe Who performing, wearing IEM's fitted by Harley Street Hearingement for the artist
  • 26dB of isolation eliminating stage volume and ambient noise – critical for performing musicians and audiophiles alike
  • Control of volume, helping to safeguard hearing and reducing voice fatigue
  • A clear and uncluttered stage, improving audience sightlines
  • The reduction of on-stage volume, which improves front-of-house sound
  • Overall improvement in monitoring sound quality, more precise, more consistent.

Live performance monitoring

As the name suggests IEM’s allow the performer to more effectively monitor their own performance whilst utilising the noise reduction properties to help protect their hearing for the future. The sound engineer can combine signals from multiple sources (instruments) and create an individual mix for each performer on stage. Each performer is able to set the mix as they wish, thus meaning that members of the band hear slightly more or less of certain instruments without effecting the over all sound produced by the band.

Personal In-Ear-Monitors are custom moulded using miniature balanced armature transducer technology to deliver the ultimate in sound quality. The tiny magnetic receivers offer high resistance to mechanical shock and deliver smooth responses with very low distortion levels. In ear monitors reduce the ambient sound environment by approximately 26 dB. This reduction in the outside noise allows for a safer, lower listening volume from the source whilst at the same time delivering a superbly detailed sound reproduction.

In Ear Monitors

Which style monitors are suitable for me?

IEMs are generally categorised by the number of transducers (drivers) they have within them. It is often useful to think of the number of drivers like the number of speakers in a sound system.

Single driver IEMs Single modular unit.

A wideband single driver unit providing the isolation benefits of IEMs whilst delivering a detailed sound across a large frequency range. Often viewed as an entry level set up.

Dual Driver IEMs

Dual driver IEMs feature a designated subwoofer to deliver a more accurate low frequency response whilst maintaining crisp and clear high frequencies.

Triple Driver IEMs 

Triple driver IEMs separate the sound into Low end, mid-range and high end, to deliver an unbiased audio reproduction. Used by people seeking the highest possible sound quality.

IEMs are only as good as the Impressions taken…

As previously stated IEM are custom made for you. To do this we take deep impressions of your ears using a fast setting Silicone composite. The IEM’s are then made uniquely for you and the shape of your ears with all of the components being built into the moulds.

Custom moulded in-ear-monitorsThe moulds should be taken:

  • With no wax present
  • Past the second bend of the ear canal
  • With a cotton stop
  • With an open jaw

As all the components of the IEMs are built into the moulded shells, the monitors are only as good as the impressions taken.

Good impressions will ensure that the IEMs are comfortable, have a good acoustic seal and deliver the best possible sound quality.

Here at Musicians Hearing Services we ONLY allow qualified Audiologists to do this for you. All staff have had a minimum of 4 years training with further post qualification experience so you know you’re in safe hands.

This is why we are the recommended UK audiologists for all major IEM brands.
