Extended Response Earphones
Etymotiv - ER2XR
Beyond the Effect HorizonThe ER2XR delivers renowned Etymotic passive isolation, with 35-42 dB attenuation. You can hear every detail of music with lower volume levels that are safer for your hearing. The flat mids and highs, along with the emphasized bass of the ER2XR, will appeal to consumers and audiophiles who like a little more presence of bass.
The ER2XR 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. Included is a user-replaceable cable.
The ER2XR earphones are perfect for musicians, audiophiles, and consumers on a budget, who are looking for in-ear monitors that are easy to drive, and prefer the added warmth in the bass frequencies.

Etymotic’s Target
flat frequency responseEtymotic’s target frequency response graph represents a “perceptibly flat” frequency response. The goal is to have a flat frequency response curve when the music notes hit your eardrums. To achieve that, the resonance inside the average ear canal needs to be accounted, since 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. That is the reason for the “hump” in that region.
The target curve that Etymotic is using for tuning our IEMs differs slightly from the Harmon preference curve. It was developed in-house more than 20 years ago, leveraging on human hearing expertise and acoustics research.
Accurate Earphone ReproductionWhen tuning in-ear monitors to accurately reproduce a recording of a live performance, the goal is for the sound hitting the eardrums to be identical to that at the original performance. To achieve this, the acoustic properties of the ear must be factored in.
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 graph, which assures the eardrums perceive a perfectly flat frequency response for all frequencies.
