The in-ear monitors (IEMs) are a kind of headphones that enter the ear canal to a certain depth and completely plug the ear, isolating from external noises and providing deeper bass reproduction. The best in-ear monitors are widely used by musicians, DJs, singers, television presenters, audio engineers, and audiophiles as they ensure outstanding sound quality and high level of comfort.

The IEMs are mainly designed for professionals (to be used on the show, in recording studios, etc.). For instance, they make singing much easier: thanks to the superior noise isolation provided by the IEMs, the vocalist hits the notes more often and the vocal cords strain less. This is especially important at gigs where the audience can be extremely noisy. Of course, the in-ear monitors may not be a great solution for musicians who are used to hear their amplifiers, but they are definitely suitable for those who need to hear their tracks more cleanly and accurately.

Despite the fact that the in-ear monitors are the most sought-after among people who work in the music industry, they also do well as the usual earbuds. Particularly if you want something that has better noise-isolating capabilities than regular headphones. They also stick into the ears much more firmly than the usual earphones so they can be a great solution for workouts.

Choosing the IEMs, you obviously want a high-quality product that offers a true frequency response and is comfortable for hours of wearing, especially if you are a professional musician. However, all the models come in different shapes and sizes, have different functionality, so it can be hard to find the product that perfectly coincides with your needs. Thus, our top picks and buyer’s guide are aimed to help you with finding your best IEM.

How to Choose In-Ear Monitors?

There are many things that you should take into account when looking for the best in-ear monitors. For instance, the number of drivers. It’s common to think that more drivers are better as they provide a wider dynamic range, but, in fact, that’s not what everyone needs to overpay for. Some of them may have from 8 to 12 drivers. This, of course, significantly extends the frequency brackets, but for a non-professional use, it can be useless. When choosing the IEMs, your budget and your needs are the main things that you should consider. Think about how loud the stage you are performing on will be so you could make sure that you will hear your voice or your instrument well enough.

If you have a limited budget, don’t spend your money on the device with unusual design and features that have no practical value, like colorful backlight, for example. Concentrate on the device’s specs.

You can get whether universal or custom-molded option. The last one is made specifically for your own ear canal so provide a better seal on your ears, superior noise-blocking properties, and feel more comfortable, but it is also more costly. If you are getting a universal fit, make sure that some extra tips of different sizes are included in the package.

If you want the in-ear monitors for sports, it’s better to choose the model with a headband. It will eliminate the risk that the IEMs fall out of your ears. Such in-ears also should have at least an IPX5 waterproof rating so the sweat couldn’t get to the dynamics and damage them.

Wired or Wireless

Many people think that all the IEMs are wireless because that what they used to see most often when the artist performs on the stage, but that’s wrong. Like all the sound systems, they can be whether wireless or wired. Moreover, wireless models are not the most widely used ones. The musicians who don’t move around a lot and don’t actually need freedom of move usually prefer wired models. Some manufacturers even don’t produce wireless transmitter/receiver units.

Which model will be more beneficial for you actually depends on your position in the band. For example, if you are a drummer or a keyboard player, the wireless in-ear monitors don’t make a lot of sense for you due to your static position. The wired options provide a cleaner sound and you don’t have to worry about audio dropout or interference. Plus, they cost much less than their wireless analogs.

Lead singers and guitarists, in fact, will have more advantages when using the IEMs without a wire since they allow total freedom of movement. They include a transmitter device in which you connect the output from the mixing console and a receiver unit that receives the signal from the transmitter and feeds it into your IEM headphones. However, note that the wireless options are more expensive and more complex. This way, we recommend not to go for a wire-free model when there are no particular reasons for it as you simply won’t get too much benefit from this solution.

Audio Features

Noise reduction. Despite the size, the large in-ear monitor headphones, even if they are supplied with Active Noise Cancellation technology, not always ensure better noise isolation than the compact IEMs do. It measures in decibels which indicate how much environmental noise is blocked by the in-ears: the higher the number the more noise is being blocked.

Frequency response. This indicator shows what frequencies the IEMs are able to produce. The models that cover a bigger range are better since the frequency response is responsible for the sound quality. On the average, the good in-eras have approximately 25000 Hz frequency response which is enough to be able to transmit maximum sound details.

Impedance and sensitivity. The professional high-end in-ear monitors tend to have very high impedance values which means that they need a lot of power from the unit they are hooked up to give out similar volume levels. Sensitivity measures in decibels (the advanced models have a sensitivity of at least 100dB) and shows how much volume the IEMs dynamics will produce. It also affects the amount of power needed to produce a certain amount of volume.
