Reviews last updated: November 2026 · How we calculate this

What customers like about Denon AH GC25NC

  • Amazing Hi-Res audio quality with crisp highs and deep bass
  • Excellent active noise cancellation with three specific environment modes
  • High level of comfort for long-wear sessions due to memory foam earcups
  • Strong passive noise occlusion even when ANC is turned off
  • Long battery life of up to 40 hours for noise cancellation
  • Convenient ambient monitor feature (tap-to-hear announcements)

What customers don't like about Denon AH GC25NC

  • Reports of poor durability regarding the synthetic leather on ear pads peeling quickly
  • The controls can feel a bit fiddly or difficult to use initially
  • Requires an additional amplifier to reach full potential for high-res audio
  • Some users find them heavy and uncomfortable compared to newer alternatives
  • Outdated micro-USB charging port and lack of wireless/Bluetooth connectivity

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.
