Sound7.8

The Drop + Dan Clark Audio Aeon Closed X is a closed-back planar magnetic headphone with a neutral, clean sound, tight bass, and crisp treble, though it can be sibilant and benefits from EQ. It offers good isolation and ergonomics at a $499 price point.

The HearWiki takeAI-condensed

The Dan Clark Audio Aeon Closed X is a wired, closed-back planar magnetic headphone that delivers a neutral-leaning sound with clear mids, punchy bass, and deep extension. It stands out for its light weight and spacious soundstage for a closed design, though it can sound sharp in the treble without its damping inserts and benefits from a capable amplifier for best performance.

What works

  • Lightweight for a planar magnetic design
  • Neutral, detailed sound with clear mids and punchy bass
  • Unusually spacious soundstage for closed-back headphones
  • Good imaging and layering for the price

What doesn't

  • Treble can be sharp without included damping inserts
  • Damping inserts reduce dynamics when used
  • Benefits from ample amplifier current despite low impedance
  • No built-in controls or customization options

The review emphasizes the headphone’s very light weight for a planar magnetic model, along with its small proprietary driver and low impedance/high sensitivity combination. It also notes that the headphone can be demanding despite those specs, because it still benefits from ample current delivery.

DCA Aeon Closed X - The All-Day Closed-Back?

MrAyrit7.9K viewsJan 2022

The reviewer finds the Aeon Closed X to be an exceptionally comfortable, lightweight, and well-built headphone, ideal for all-day background listening. However, the sound is described as adequate but unremarkable, lacking extension and excitement, though the included tuning pads allow for some customization. Overall, it's a decent headphone that fits a specific niche rather than being a standout for critical listening.
