Verdict

The Denon AH-GC25NC is a premium wired over-ear headphone featuring 40mm FreeEdge drivers that deliver Hi-Res certified sound with a wide frequency response of 5 Hz to 50,000 Hz and a 16-ohm impedance. It is distinguished by its triple-mode active noise cancellation (Flight, City, and Office modes) and an integrated ambient monitor that allows external sound pass-through with a simple tap on the earcup. Main pros include its exceptional 40-hour battery life for noise cancellation, high-quality memory foam ear pads for extended comfort, and a lightweight, foldable design weighing 287g. However, notable cons include the lack of wireless Bluetooth connectivity, the use of a micro-USB port rather than USB-C for charging, and user reports of the synthetic leather on the ear pads peeling over time.
