Over the past 20 years,Â In Ear MonitorsÂ (orÂ IEMs) have become a near-necessity for live performance.
In years prior, engineers would inevitably have to crank up a venueâs stage monitors loud enough for the musicians to hear themselves over the audience, over the sound coming from the stage, and over the main mix.
This would often lead to an arms race of ever-increasing stage volume, potentially causing feedback issues and compromises in clarity and quality for the live mix.
Custom in-ear monitors from JH Audio, one of the first commercial brands to make a name for itself in the IEM market.
With the advent of in-ear monitors, all this began to change.Â In the mid-1980s,Â EtymoticÂ developed the first-ever insert-styleÂ earphones, and soon after, a designer namedÂ Marty GarciaÂ began making one-off custom in-ears for rock stars like Todd Rundgren.
By 1995, Jerry Harvey, founder ofÂ Ultimate EarsandÂ JH Audio,Â brought some ofÂ the first commercially-available dual-driver IEMs to market. All of a sudden,Â everyday musicians had an option that allowed usÂ to save our hearing, get better monitor mixes, and dramatically reduce the chances of feedback onstage.
Today, IEMs are increasingly being considered useful tools for the studio as well. Their ability to prevent sound leakage can be of tremendous value in helping to control click and instrument bleed, and in saving musiciansâ hearing by allowing them to monitor at lower levels.
Some musicians and engineers, such as drummer Rich Pagano ofÂ The Fab Faux, will use IEMs to quickly check for phase when micâing up a drum kit, while others turn to IEMs as a kind of audio microscope, using them to help check for and remove extraneous low-level noise.
Any modern musician would be wise to consider adding in-ear monitors to their toolkit. But is it worth it to dish out the extra money on custom fit IEMs, instead of saving some money with the generic fit ones?
In testing a variety of in-ear monitors from brands like Westone, Ultimate Ears, Future Sonics, and even Skullcandy (that last of which is not recommended for professional use), I have found that there are cases in which generic fit earphones may work better than their custom counterparts. Making the right decision for your needs comes down to considering the following four factors:
Ultimate Ears custom fit in-ear monitors.
Custom fit IEMs tend to cost more than generic fit ones, as it takes more time and effort for the manufacturer to craft a product designed specifically for the unique anatomy of your ear.
Getting custom IEMs made also requires that you go to an audiologist to make a mold of your ear canal that the IEM company can then use to make your monitors fit as well as possible.
Take note of both of these costs, which can range from $100-$200 or more for a fitting from an audiologist, and $299-$1499 or more for the custom monitors to be made.
2)Â Comfort & Seal
Custom fit IEMs areÂ custom, so they should feel really comfortable, right? Â Well, yes and no.
In my experience, custom fit IEMs can feel a little tight in the ear canal compared to generics, especially at first. Hearing so little acoustic feedback from your performance can also take some getting used to, and the tight seal of custom fit in-ears can feel particularly awkward when signing.
Because of this, my looser-fittingÂ Westone 3Â generic IEMs actually feel more comfortable to me on vocal duties, so I often find myself using them over my custom fitÂ Future SonicsÂ when I step up to the mic.
Matt Bellamy from MuseÂ (recently featured inÂ Get THAT Guitar Tone) has been seen using both customUltimate Ears UE-11s and generic-fitÂ Westone UM2s when on tour, and my guess is that he has similar reasons.
Though the tight fit of custom IEMs and lack of acoustic feedback from your performance can be a challenge, itâs worth noting that generic foam-tip IEMs also provide their own tradeoffs: The looser fit of generics can sometimes create a bit of a tingling or âticklingâ feeling in your ear when playing at higher volumes, so it may be useful to have a pair of each and go with what feels best depending on the date and venue.
Silicone-based Encore Studio custom IEMs from ACS.
Another option here is the custom fit brandACS, which makes its IEMs out of soft silicone shells.
This softer silicone-based design is meant to offer both better comfort and a tighter fit than the hard acrylic shells used by brands like Westone and Ultimate Ears.
Though these silicone monitors sell for a premium price of $400-$1,200 and up, they may help bridge the gap between the tight seal of custom acrylics and the looser and easier fit of foam-tipped generic IEMs.
3)Â Hearing Protection
In addition to cutting down on sound leakage to help improve sound quality and reduce feedback, another primary benefit of IEMs is that they can offer considerable hearing protection by helping to block out exterior noise, allowing you to monitor at lower levels.
Some of the best custom fit brands likeÂ JH AudioÂ andÂ Ultimate EarsÂ offer NRR ratings of 26dB in reduction, and some of the better generic brands advertise comparable results as well. (Though your results with generics may vary depending on the fit and seal in your ear.)
In the long term, reducing the levels youâre regularly exposed toâeven by a few extra decibelsâcould mean the difference between a long and illustrious career as a âgolden-earedâ audio engineer and potentialtinnitusÂ and irreversible hearing loss.
Also worth checking out is theÂ REV33Â system, which can be added on to yourÂ your in-ear-monitoring system to help reduce distortion and ear strain. Many live musicians, includingÂ Phil XÂ and Steve Salas swear by the system. According to the company:
âAll in-ear monitors and headphones generate damaging, unwanted noise and distortion that forces the ear to shut down and compress for protection. The REV33 reduces the symptoms of tinnitus, ear-ringing, ear-fatigue, buzzing and dampened hearing by preventing in-ear monitors and headphones from producing this unwanted noise and distortion.â
4)Â WaitingÂ and TimeÂ Considerations
After getting my first pair of IEMâs made, I found that the right ear monitor turned out well, but I was not getting a proper seal in the left ear at first. This made the monitors essentially useless for my live sound needs at the time, and so I had to send them back for some tweaking.
When I got them back a couple of weeks later, the seal still wasnât great, so I had to send them back once again for further modification, and visit my audiologist a second time to take another impression of my ear canal to send in.
Getting the perfect fit turned out to be quite a time-consuming process (as well as an expensive one) so unless youâre on the hunt for a long-term solution with as much acoustic isolation as humanly possible, you might satisfice with generic IEMs, or keep some around as an alternate option.
In that case, I would recommend the generic in-ears from Ultimate Ears, Shure, or Westone.
Ultimate Earsâ generic fit UE900 model sports 4 drivers for $400.
TheÂ Ultimate Ears UE900âs are a great sounding 4-driver IEM that only costs $399, while the $99Â Shure SE215Â single-driver IEMs advertise an astonishing 37dB of noise reduction (more than most custom IEMs) at a great price.
My own triple-driver Westone 3âs (since replaced by theÂ W30 model) are the most comfortable in ear monitors I own right now, and they isolate a lot more noise than most thanks to their foam-tip construction.
Compared to custom in-ears, any of these model can potentially save you time and money, or work as a welcome supplement for those times when the tight fit of custom in-ears feels irksome.
I hope my experiences here help you make the right decision when you go to buy your own IEMs. In short, I found that less-expensive generic foam-tipped IEMs worked better for me in many situations, and the savings enabled me to spend my money on better drivers with a fuller sound.
