In Ear Monitor Buyer’s Guide: Custom vs. Generic Fit

writer:admin pubdate:2017-01-08 12:22 view:()

Over the past 20 years, In Ear Monitors (or IEMs) have become a near-necessity for live performance.
 
In years prior, engineers would inevitably have to crank up a venue’s 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 brands to make a name for itself in the IEM market.
 
With the advent of in-ear monitors, all this began to change. In the mid-1980s, Etymotic developed the first-ever insert-style earphones, and soon after, a designer named Marty Garcia began making one-off custom in-ears for rock stars like Todd Rundgren.
 
By 1995, Jerry Harvey, founder of Ultimate Ears and JH Audio, brought some of the first commercially-available dual-driver IEMs to market. All of a sudden, everyday musicians had an option that allowed us 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 musicians’ hearing by allowing them to monitor at lower levels.
 
Some musicians and engineers, such as drummer Rich Pagano of The Fab Faux, will use IEMs to quickly check for phase when mic’ing 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.
1) Cost
 
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) Comfort & Seal
 
Custom fit IEMs are custom, so they should feel really comfortable, right?  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-fitting Westone 3 generic IEMs actually feel more comfortable to me on vocal duties, so I often find myself using them over my custom fit Future Sonics when I step up to the mic.
 
Matt Bellamy from Muse (recently featured in Get THAT Guitar Tone) has been seen using both custom Ultimate Ears UE-11s and generic-fit 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, it’s 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 “tickling” 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 brand ACS, 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) 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.
