ER3SE is the highest-sensitivity single driver in-ear monitor. The IEM shells are made of anodized aluminum, CNC machined with extremely tight tolerances. Using a single Balanced Armature (BA) driver allows for extremely accurate IEM without the added complexity of crossovers, and helps keep the aluminum body small and slim. Included is a user-replaceable cable.
The HearWiki takeAI-condensed
The Etymotic ER3SE is a wired, single balanced-armature in-ear monitor built for accurate, reference-style sound with a lean, neutral tuning. Its deep-insertion design delivers class-leading passive isolation, making it a strong choice for analytical listening in noisy environments, though it lacks consumer-friendly bass warmth and features.
What works
- Accurate, neutral reference tuning
- Excellent passive noise isolation
- Compact, durable build with accessories
- Strong detail retrieval for its price
- Good value when discounted
What doesn't
- Lean bass response may disappoint bass lovers
- Deep insertion fit not for everyone
- No inline controls or app support
- Limited frequency response above 16 kHz
