All About In-Ear Monitors

Today we're going to talk all about in-ear monitors (IEMs) – wireless headphones used to listen to music or to hear a custom crafted mix of vocals and stage instrumentation for live performance (or recording studio mixing).They are often custom fitted for a player’s ears to not only provide comfort, but more importantly, to give a high level of noise reduction from competing sounds (such as the drummer right behind you if you’re a singer).  Anyways, the reason as to why they were wearing these wasn’t what surprised me as it has gotten pretty common for bands to employ in-ear monitors instead of floor speakers in order to better hear themselves, but the fact that they were all using them – something that would have been unheard a few years back thanks to their enormous price.  

In the history of modern music, in-ear monitors have only really been around for a short amount of time. First introduced in the late ‘80s, they only recently became affordable to the average consumer a little over 10 years ago, but it wasn’t until recently that their use has seen enormous growth, especially in the touring industry. Many live bands and acts use them regularly and for some tours, they’re pretty much essential! Although in-ear monitors are pretty much made to do the same job a floor monitor would, the reason so many prefer them is mainly due to the freedom they can give the performer, especially singers. The ability to have a consistent sound not matter wherever you go onstage has enabled uncluttered stage design, increased freedom of movement and even enhanced performances. Along with wireless microphones, they are pretty much a common sight on many tours.

For those of you who have never seen or used in-ear monitors, they are essentially comprised of a two part system; a transmitter which transmits the monitor mix wirelessly (via radio) and a receiver the performer wears – usually the size of a smartphone with and input for headphones – which receives the signal. This picks up the monitor signal and amplifies it through a pair of earpieces. The transmitter and receiver operate in the UHF band, between 606 and 614 MHz. Other bands are available, but some require a special license.

Before you go out and decide that you might one some in-ear monitors for yourself, there are a few things that you should know. Anyone who has used radio equipment before will know that interference and dropouts are always a potential issue, and the increasingly busy wavebands are making finding clear frequencies a lot harder than it should be. However, modern systems tend to use carrier signals, which lock the belt pack onto the transmitter’s frequency, and this has done a lot to calm interference problems. Also – as with any radio signal – dynamic-range compression and reduced bandwidth compromise audio quality, but the good news is that technology has become increasingly sophisticated and today’s modern in-ears can deliver high-fidelity sound with reasonable consistency. Modern systems are also very stable and produce a good-quality signal, and though the sound is not quite up to hi-fi standards (due to the restrictions of broadcasting) the advantages of being wireless, and the freedom this provides, usually outweigh any minor sound-quality concerns.

You should also know that the earphone side of in-ear systems can vary greatly in price and quality. Most systems are provided with you with generic buds — the kind of headphones you would normally get with MP3 players (not the best in the business to say the least). The next step up from there is a generic mould; these are more ear-canal shaped and fit a bit more snugly, making them less likely to come out and offer better noise reduction. The best option – and the ones most professionals employ – is to have a mould taken of your ear and a custom ear bud made for you. These vary in price depending on the model and can range anywhere from a little over one hundred dollars to one thousand. Custom moulds have the advantage of being a snug and usually the most comfortable. And best of all, they cut out a lot of external noise which makes them great for loud stages. But with all of the added noise reduction, they can easily lead to a feeling of detachment – especially for those new to in-ears – which makes you reliant on a properly balanced mix in order to compensate. Still though, it’s nothing a few good weeks or months of use can’t fix. Alright, now that we know a bit more about in ear-monitors, let’s check one out to get a better sense of what they can bring to the table. And don’t worry; we selected one of the best pro-quality, affordable models around.
