circumaurales

Circumaurales, commonly referred to as circumaural headphones, are a type of over-ear headphone whose earcups fully enclose the listener’s ears. The surrounding cushions and seal around the ear aim to reduce ambient noise and deliver a more consistent sound, especially in the low frequencies. This design contrasts with supra-aural or on-ear headphones that rest on the ear.

Most circumaurales are larger and heavier than on-ear designs, and comfort depends on headband clamping force and ear cushion design. They are produced as closed-back models, which trap sound and provide passive isolation, and open-back models, which offer a more natural sound but less isolation and potential sound leakage. Open-back versions are often chosen for critical listening, while closed-back variants are preferred when noise isolation is important.

Construction and performance vary: common driver sizes range from about 40 to 50 mm, with some models using planar-magnetic or other driver technologies. Impedance and sensitivity vary by brand, influencing the required source power and listening volume. Materials for cushions include leatherette, memory foam, or fabric; many designs use replaceable pads. The headband and overall build affect comfort during extended use.

Applications include professional studios, critical listening, mastering, broadcasting, gaming, and general consumer use. Open-back circumaurales are favored for a wide, expansive soundstage, whereas closed-back versions provide greater isolation and reduced sound leakage.

Maintenance considerations include cushion wear, which can be mitigated by replacing pads, and routine cleaning of grills and housings to preserve performance and hygiene.
