High-Sensitivity In-Ear Monitors
Etymotic - ER2SE (Studio Edition)
clear, accurate sound using high performance dynamic driversThe Etymotic ER2SE offers passive isolation with 35-42 dB attenuation. This enables you to hear all the details in the music with lower volume levels that are safer for your hearing. The flat frequency response of the ER2SE will appeal to sound professionals and audiophiles alike.
The ER2SE shells are made using anodized aluminum, CNC machined with extremely tight tolerances. Using a single dynamic driver allows for a very accurate IEM without the added complexity of crossovers, and helps keep the aluminum body small and slim. A user-replaceable cable is also included. The ER2SE in-ear monitors are perfect for sound engineers, audiophiles, and consumers on a budget, who are searching for in-ear monitors that are easy to drive while offering accurate audio reproduction.

Flat Frequency Response Curve
designed by expertsEtymotic’s target frequency response graph displays a “perceptibly flat” frequency response. Their goal is to have a flat frequency response curve when the music reaches your eardrums. To achieve that, the resonance inside the average ear canal needs to be accounted for, as IEMs bypass the outer ear structure. The result is the need for higher SPL in the 2-5k region (lower treble) for compensating said resonance, which is the reason for the “hump” in that region.
The target curve that Etymotic is using for tuning their IEMs changes slightly from the Harmon preference curve. It was developed in-house over 20 years ago, leveraging on Etymotic's human hearing expertise and acoustics research.
Accurate Earphone Reproduction
every element consideredWhen tuning in-ear monitors to accurately reproduce a recording of a live performance, the goal is for the sound to be identical to that of the original performance. To achieve this, the acoustic properties of the ear must be considered.
The acoustic resonance and horn effects of the ear change a flat audio signal entering the open ear into sound with a (2700 Hz) high-frequency boost, which is the same response heard at the eardrum in a typical ear. That is the reason for the “hump” in the frequency response, which assures the eardrums perceive a perfectly flat frequency response for all frequencies.
