Custom In-Ear Monitors Reviews List


Welcome to the custom in-ear monitor reviews list page. Custom in-ear monitors are earphones, AKA in-ear headphones, that are custom fitted to your ears and offer the best sound quality, excellent isolation, and long-term comfort for use anywhere. At The Headphone List, we believe perspective is important, and our scores are based on technical performance from comparative listening tests. All of the reviews on this page have been published by average_joe, so you can expect a consistent perspective. Click on the Model link to read a review, most of which contain comparison sections.

This interactive list allows for filtering to drill-down to what you really want, with products sorted by overall sound score. However, we do strongly advise making any buying decisions based on your preferred sound signature and not just the score and suggest you read The Best Headphone for more persepctive on why. The "Show other types of headphones for reference" is now checked by default, and you can uncheck it to see only custom in-ear monitors. Mouseover the header titles for more information about the column.

There are many great options in this list, but to find some excellent choices without too much research, visit the Custom in-ear monitors buyer's guide. Don't miss the Best Headphone article to see why sound signature is important. If you still need to figure out your preferred sound signature, listening to some of the options listed in the Earphone buyer's guide by sound signature can help you figure it out.

Our goal is to help you make the best, most informed decision, so feel free to ask questions in the comments and let us know what you think of the site and reviews. Visit the Multi-IEM review list by ljokerl for more reviews including hundreds of universal-fit earphones.
