What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Our last collaboration with Dan Clark Audio—the Aeon Open X—was an instant hit in the world of planar magnetic open-back headphones. Now, we're unveiling it in a closed-back variation: the Aeon Closed X. A refinement of the Aeon Flow Series, these passive-isolating headphones feature the same warm and punchy audio, excellent power response, and ultra-comfortable fit as their predecessors. Where they improve on the Flow Series is in the soundstage: we added partially fenestrated earpads and reduced driver dampening to even the tone and minimize reverberation. Now featuring new, carefully selected earcups, the individually serialized Aeon Closed X gives listeners the best of both builds: closed-back isolation with an open-back-caliber soundstage.

Brand highlights

Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:

Massdrop x Beyerdynamic DT177x GO Headphones  

  • Positioning: The entry-level headphone designed for affordability and portability.  
  • Description: Offers a balanced sound with a design focused on basic dynamic drivers and ease of use, making it well-suited for everyday listening in smaller spaces. Compared to the more premium options in the lineup, it provides fewer advanced features and lower build sophistication, appealing to budget-minded users with basic functionality requirements.

DROP + MrSpeakers Ether CX Closed Headphones  

  • Positioning: A mid-range closed headphone aimed at balancing planarmagnetic performance with cost efficiency.  
  • Description: Delivers a refined tonal balance through its V-Planar driver design and a smoother bass-to-midrange transition, setting it apart from typical dynamic driver designs. Compared to other models like the Aeon series, it offers a unique closed design that favors controlled listening settings and moderate build enhancements.

DROP + Dan Clark Audio Aeon Closed-X Headphones  

  • Positioning: A mid-range closed headphone that emphasizes improved tuning and comfort for detailed midrange performance.  
  • Description: Uses Dan Clark Audio's custom driver technology for a vibrant and natural sound without the extreme emphasis on any frequency band.
