Etymotic ER2SE Studio Edition earphones

These are the Etymotic ER2SE Studio Edition earphones, a high-fidelity in-ear monitor known for its flat frequency response and exceptional isolation. The ER2 series represents a significant shift for the brand as it utilizes a high-performance dynamic driver rather than the balanced armature drivers traditionally associated with the company.

Historically, Etymotic Research was an American company founded by Edwin Killian, focused on hearing health and high-end audio engineering. In recent years, the brand was acquired by Lucid Audio, which subsequently became part of the Lucid Hearing group. While the research and engineering legacy is rooted in the United States, the manufacturing for the ER2 line is primarily located in Vietnam.
