What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Select products
Select product comparisons
ER2SE
- Position: Entry-level studio reference model with flat frequency response for accurate monitoring.
- Description: Features a dynamic driver that delivers weightier bass and better dynamics compared to the balanced armature models in the lineup. While it offers less refinement than the ER4SR, it provides more impactful low-end response and dynamic contrast.
ER2XR
- Position: Entry-level model with enhanced bass response for listeners preferring more low-end presence.
- Description: Uses the same dynamic driver as the ER2SE but adds extra sub-bass emphasis below 100 Hz for a warmer sound signature. This model provides more bass impact than any other Etymotic model while maintaining the company's signature noise isolation.
ER3SE
- Position: Mid-tier studio reference model with high-sensitivity balanced armature driver for portable devices.
- Description: Features a single balanced armature driver with higher sensitivity than the ER4 series, requiring no amplification for portable players. Offers more refined sound than the ER2 series with better instrument separation and airiness, though it lacks the ultimate resolution and refinement of the ER4SR while providing easier drive requirements for mobile use.
ER3XR
- Position: Mid-tier model with enhanced bass and high sensitivity for portable use without amplification.
- Description: Builds on the ER3SE's balanced armature design with added low-end emphasis for a warmer signature than the studio version. Provides clearer sound than the ER2XR with better detail retrieval and instrument separation, while offering easier drive requirements than the ER4XR.
ER4SR
- Position: Flagship studio reference model with precision-matched balanced armature drivers and flat response.
- Description: Uses Etymotic's most refined balanced armature driver with precision channel matching and comes with comprehensive accessories including multiple tip types and a hard case. Delivers superior resolution, airiness, and instrument separation compared to all other models in the lineup, though with less bass impact than the dynamic driver ER2 series.
ER4XR
- Position: Flagship model with enhanced bass response and the highest technical performance in the lineup.
- Description: Shares the same precision-matched balanced armature driver as the ER4SR but with enhanced low-frequency response for a warmer signature. Offers the most transparent and open sound in the entire lineup with superior detail retrieval and soundstage compared to all other models, while providing more bass presence than the ER4SR.

Our take on the brand
Etymotic pioneered the first noise-isolating hifi in-ear earphones in 1991 and originates from audiology and laboratory insert-earphone development, which gives it a clinical-grade technical pedigree uncommon among hifi brands. The brand is known for deep-insertion designs that achieve exceptional passive isolation of 35-42 decibels, diffuse-field reference tuning, and user-replaceable acoustic filters that allow fine sound tailoring without hardware modifications.
