What customers say
The Etymotic ER2SE earns high praise for its accurate, uncolored sound signature, often called a true reference monitor.

Know before you buy
The Studio Edition (SE) is tuned for a flat, neutral frequency response. This means the earphones aim to reproduce audio exactly as it was recorded, without boosting bass or treble, making them ideal for critical listening and professional monitoring.
Etymotic is famous for its deep-insertion design, which provides 35-42 dB of passive noise attenuation. This physical seal blocks out significantly more high-frequency ambient noise than most active noise-canceling headphones, though it does not use electronics to cancel out low-frequency hums.
With an impedance of 15 Ohms and a sensitivity of 96 dB, the ER2SEs are relatively easy to drive. You should be able to achieve sufficient volume levels using most standard mobile devices or computers without needing a dedicated external amplifier.
Yes, the ER2SE features a detachable 4-foot cable with an MMCX connector. This allows you to easily replace the cable if it wears out or breaks, extending the overall lifespan of the earphones.
Comfort is subjective, especially with the deep-insertion fit required for Etymotic's isolation. The package includes an assortment of eartips, so you can experiment to find the best seal and comfort level for your ear canal shape.
