The 5 Best Wireless In-Ear Monitor Systems

Last Updated: June 30, 2021

If you are in a hurry and just want to find out what the best wireless in-ear monitor system is then I’d recommend Sennheiser Pro Audio G4-Twin-A1 In-Ear Monitor System as the best one.

Musicians, performers, and audio engineers are usually the ones who use in-ear monitors (IEMs). This device comes with a pair of earbuds that block out the noise surrounding the user. 

Using the earpiece, the performer can listen to their instrument or vocals during the performance. In-ear Monitor systems are called “monitors” because they were designed for performers to monitor a combination of sounds that come from different places. 

There are several choices of wireless IEMs in the market, and choosing can be overwhelming for beginners. Here, we’ll be reviewing the following wireless in-ear monitors to introduce you to some great products.

Here are the Best Wireless In-Ear Monitor Systems we’ll be reviewing:

Why Choose a Wireless In-Ear Monitor System

By using a wireless in-ear monitor system, the stage volume is lowered. This allows the performer to clearly hear their music/vocals. Moreover, this protects the performer’s ears from too much stress from too many loud noises.

Having IEMs allows you to omit the use of stage monitors. This is because what’s happening on the stage can already be relayed through the earpiece.

IEMs are shaped to fit comfortably in the ears. This is very important as performers often use these for several hours.

IEMs are portable, and wireless IEMs allow the performer to freely move around the stage.

How Does a Wireless In-Ear Monitor System Work?

To put it simply, the IEM system uses high radio frequencies to transmit sound, which in this case is called a mix. The performer wears a wireless receiver pack (a belt pack) and this is where the earpiece is plugged into. The wireless receiver receives a mix from the transmitter that is connected to a mixer or the sound desk. 

The antennas on the receiver pack pick up the signal and convert it into audio. The earphones allow the performer to listen to and adjust the volume of the monitor mix. 

Things to Consider in Buying a Wireless IEM System

A good wireless in-ear monitor system can greatly improve the overall quality of your performance. This is an investment you have to plan before getting one. Last June 13, 2020, the Federal Communications Commission issued an ordinance that says older wireless systems that operate under frequencies 617-652 MHz and 663-698 MHz are no longer allowed in the US. 

However, the products that are allowed to be used are still a lot and you might need some guidance in choosing the best wireless IEM system for you. Here are some factors you might want to consider before purchase.

Multi-channel mixing

One thing you have to take into account is the product’s leverage in terms of personalization. Multi-channel mixing allows the user to take control of the audio monitoring process. This enables the performer to make adjustments as they please. When done right, multi-channel mixing will allow you to hear yourself better and help you achieve your desired results.

Frequency Range

Each wireless in-ear monitor system operates at a different frequency. Some wireless systems even have an alternative variety that works in a different frequency band. 

There is also a risk of interference as these frequency bands are unlicensed. It would be wise to consider the system’s frequency range so you can maximize the use of IEM systems that can work simultaneously. By doing this, you can have a backup in case the frequency is compromised. 

Lastly, it’s important to familiarize yourself with how the whole system works in case there’s a time when you have to set the frequencies yourself.

Frequency Response

Different kinds of musicians focus on different ranges. The wireless in-ear monitor’s frequency response determines what kind of frequencies the earpiece can produce. The lower starting range produces bass sounds, while the top range indicates high frequencies. This may be a case-to-case basis so you would have to decide which wireless IEM system to purchase based on your needs. 


How’s the earpiece? Consider the material of the earbuds and their fit. Does it feature a universal fit or a custom mold fit? Take note that performers would have to wear these for several hours straight so comfort is principal. I would recommend getting one that’s custom mold fit, but it could be pricey.

Receiver Battery

Lastly, you might want to decide what type of battery you would like to use for your wireless IEM system. Most receivers use two disposable AA batteries. Although you can easily buy these, they can be costly in the long run, especially if you have several IEM systems. Alternatively, you can go for receivers that use built-in rechargeable batteries. These may cost more but can be more cost-effective in the future.

The perfect wireless in-ear monitor system depends on what you need and what you’re comfortable with. Here are some great choices you can check out.
