Etymotic ER2SE Studio Edition Earphone

The ER2SE's flat frequency response is designed to appeal to both sound professionals and audiophiles. Crafted with meticulous attention to detail, the ER2SE shells are made of anodized aluminum, CNC machined with extremely tight tolerances. By employing a single dynamic driver, the ER2SE achieves a very accurate in-ear monitor (IEM) without the added complexity of crossovers, while also helping to keep the aluminum body small and slim. Additionally, the ER2SE comes equipped with a user-replaceable cable.

The ER2SE offers Etymotic's renowned passive isolation, providing 35-42 dB of attenuation, effectively blocking out external noise. Both the ER2SE and ER2XR models utilize the same low-impedance dynamic drivers, but the key difference lies in the tuning of the lower (bass) frequencies. The "Studio Edition" ER2SE is tuned to have a flat frequency response, while the "eXtended Response" ER2XR is tuned with an emphasized bass, adding 1-2 dB to the mid-bass and 3-4 dB to the sub-bass.

The ER2SE is an excellent choice for audio creators and musicians on a budget, as it provides a precise and neutral sound reproduction. It is also the IEM of choice for consumers who prefer to listen to their music exactly as it was recorded. The ER2SE is ideal for sound engineers and audiophiles who are looking for in-ear monitors that are easy to drive while offering accurate audio reproduction.

In the pursuit of accurate earphone reproduction, the goal is to ensure that the sound hitting the eardrums is identical to that of the original live performance. To achieve this, the acoustic properties of the ear must be taken into account. 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. This "hump" in the frequency response graph ensures that the eardrums perceive a perfectly flat frequency response for all frequencies, resulting in a true high-accuracy sound experience.

The ER2SE features metal earpieces with an anodized finish, providing a sleek and durable design. The in-ear monitors offer 35+ dB of external noise isolation, effectively blocking out unwanted ambient sounds. Additionally, the ER2SE comes with an assortment of ear tips to ensure a perfect in-ear fit for the user. The detachable cable allows for easy replacement, adding to the overall versatility and longevity of the product.
