Things to Consider When Buying a Wireless In Ear Monitor System

The Importance of FCC 2020 Compliance

FCC regulations that came into effect on July 13, 2020 mean some older wireless systems are longer able to be legally used in the United States. The frequencies that you can no longer use are 617-652 MHz and 663-698 MHz. All of the wireless systems that we have recommended allow you to operate outside those frequencies and are compliant with the regulations. For more information read this FCC consumer guide. The regulations that apply to wireless microphones also apply to wireless in ear monitors.

Multi-Channel Mixing

This allows performers to personalize their own monitoring experience, and make necessary adjustments in real-time, while still giving the sound engineer control when needed. The end result of using this feature properly is hearing yourself better, which when set right, can dramatically improve your playing and performance.

Frequency Range

This specification details the range of frequencies that the wireless system can operate in. With careful planning, you can use this information to maximize the number of IEM systems that you can simultaneously use on stage, by buying those that can work together. Since these systems operate using unlicensed frequency bands, they can be prone to interference, so the more the range of operation, the easier it is to switch to clean frequencies as you move from venue to venue. Note that some of these wireless systems have alternate versions that operate using different frequency bands. While most wireless systems have built-in automatic scan and sync features, there may be times when you'll have to take control and set frequencies yourself. This is particularly true where multiple stages or venues are close to each other as often found in venues like casinos.

Frequency Response

This specification indicates the frequencies that the earpiece can reproduce. The lower the starting range, the more bass frequencies it can produce, while the top range dictates the high frequencies it can handle. Musicians that need to hear more lows, like bassists and drummers will want to look at those with good low frequency response. Some people even end up replacing the earpiece just to hear the lows better.

Earbuds

The earbuds play a very critical role, not only do they play the sound directly to your ear canal, they also have to block out ambient sound and at the same time hold the earpiece assembly in place. Earbuds that are bundled with readily available IEMs are generic, which means that they may or may not perfectly fit your ear, thankfully there are those that offer different sized buds, in case the default one doesn't fit well. To get the most out of your IEM system, you can go for "custom molded" earbuds that are meant to perfectly fit your ear, the caveat is that these personalized ear buds can be expensive.

Receiver Battery

Most IEM receivers are powered by two AA batteries, and since these batteries are widely available, they are the easiest to replace. Still, the cost of having to replace these batteries can add up when the receiver is used on a regular basis. Some manufacturers have opted for built-in rechargeable batteries, which can be cost-effective in the long run. One crucial thing to consider when opting for units with built-in batteries is that some of them will not be readily replaceable. Some units require you to send them to the manufacturer or service center to replace. Doing it yourself will most likely void any warranty the unit has.
