Denon's flagship wired in-ear, back at a fraction of its launch price.
Genuine Denon AH-C720 in-ear headphones in black — 11.5mm dynamic driver, 5Hz–40kHz, die-cast aluminium housings. Brand new and unused, supplied in bulk packaging (no individual retail box). Discontinued model — limited stock from our Hong Kong warehouse.
Hi-fi detail without the hi-fi rack.
The AH-C720 was built for one job: genuine hi-fi detail from a wired in-ear, straight out of a phone or portable player. Each earpiece houses an 11.5mm dynamic driver — large for an in-ear — moving more air than the 8–10mm drivers in everyday earphones. The result is deep, controlled bass, a natural midrange, and treble that extends to 40kHz, well into hi-res territory.
The housings combine die-cast aluminium with resin to damp resonance, and the oxygen-free copper cable wears a fibre-mesh cover that resists tangling, with Denon's Radial Cascade Damper reducing cable noise as you move. At 16Ω and 110dB/mW it plays loud and clean from a phone — no amplifier required — and scales up nicely with a portable DAC. No microphone, no remote: a pure listening design.
Flagship sound from a discontinued model, brand new in bulk packaging — you pay for the engineering, not the box.
