Lab data

Etymotic ER2SE Frequency Response (measured on a B&K 5128)
Click a line or a legend entry to highlight it. Click again to clear.Tap a legend entry to highlight its line. Tap again to clear.
Measured frequency response (dB relative) against the SoundGuys Headphone Preference Curve. When the measurement goes above the dashed line, that frequency is louder than our preference curve, and when it goes below: it's quieter. Use the curve for comparison purposes only, as your taste may vary.

The verdict
The Etymotic ER2SE is a great piece of hardware for enthusiasts. As with all Etymotic IEMs, you’re paying for sheer performance rather than gimmicks. The detachable housings elongate the ER2SE lifespan as listeners can easily replace the cable if it frays. The small-diameter nozzles are extremely comfortable, even more so than the famed Shure SE215. If you’re looking for high-quality in-ears, Etymotic’s headset is a smart pick.
✓Liked: Excellent isolation, Carrying case, Removable MMCX cable, Multiple ear tips of varying materials
✕Could be better: Earbuds protrude a lot, Quiet bass response, Can be uncomfortable
