Custom In-Ear Monitors Reviews List


Custom In-Ear Monitors, also known as CIEMs, provide the best sound in a tiny, portable format. They can be seen being used on TV by musicians, hosts, commentators, and more; however this site focuses on their use for audio enthusiasts and musicians.

CHARACTERISTICS
As the name implies, they are custom made to fit an individual’s ear size and tuned with each ear in mind. Due to the improved fit and precise tuning, the level of sound quality typically achieved is extremely high, as is isolation. Cables are typically worn over-the-ear and most CIEMs offer a detachable cable system and many used on stage are clear and difficult to see from a distance. Due to their custom fit, they are extremely comfortable for long-term use.

THE LIST
This interactive list displays CIEMs based on features, ratings, performance, and sound signature, not review date. In the world of audio, new doesn’t necessarily mean better! Filter the results to find the best results for your situation. Click on a model to read the detailed review with plenty of comparisons, usually on page two. We recommend buying based off the actual sound, not the score. For more info please read The Best Headphone.
