The AH-MM300 is the intermediate model in Denon's headphone range, and boasts a lightweight, elegant aesthetic design and state-of-the-art sonic technologies. They've been professionally tuned to offer a flat, untampered-with EQ, so that the music you listen to is exactly how the artist/producer intended it to be heard.

The classy design is not only intended to look aesthetically pleasing, but also enhances the overall sound quality of the listening experience. They're an on-ear model, equipped with ellipsoid earcups, built from glass fibre with a reinforced composite materials. This makes them both light-weight and highly rigid, while the ceramic finish adds to the elegance of the headphone.

These driver components are further enhanced by Denon's specialised Free Edge technology, designed to dispense the traditional diaphragm surround suspension, allowing the overall frequency response the ability to extend to 40kHz
