This three-pack of HPC-A30 Closed-Back Studio Monitor Headphones
are designed for monitoring audio in studio, field, mobile, and DJ applications. They feature 50mm drivers that provide a frequency response of 18Hz to 22kHz for accurate reproduction of your audio.
The ear cups on the HPC-A30 have an around-ear (circumaural), closed-back design, allowing for the increased isolation often desired while tracking or monitoring playback. Additionally, the ear cups can be pivoted for single-ear monitoring.
