Dan Clark Audio’s Aeon Core headphones feature an all-new planar magnetic driver, revised tuning and broader compatibility to deliver a new sub-£1000 closed-back benchmark.
The Aeon line has served as the entry point to DCA’s range since 2017, offering reference-grade planar magnetic performance at more accessible prices. The new Aeon Core headphones carry that mission forward, succeeding the Aeon 2 and delivering meaningful advances across driver technology, voicing and the measurement science underlying the tuning itself.
The Aeon Core are closed-back headphones, engineered to deliver an unusually ‘open’ sound – a particular DCA speciality.
The natural isolating qualities of their design – suppressing sound from leaking in or out – coupled to their ergonomics and electrical efficiency make them versatile and suited to a wide range of environments. They’re ideal for shared spaces and for mixing music or creating AV content, at home or in a studio.
The Aeon Core’s all-new planar magnetic driver stack was engineered around three priorities: efficiency, tonal consistency and unit-to-unit reliability. The result is DCA’s most easily driven headphones to date; in fact, they’re said to be easier to drive than most planar magnetic headphones on the market.
While offering distinct sonic advantages over traditional dynamic driver headphones including lower distortion and a more spacious soundstage, planar magnetic headphones are typically more demanding of the connected amplifier. This makes them less suited to amps with lower power outputs – particularly in terms of current delivery.
However, with sensitivity reaching 97dB/mW, the Aeon Core matches comfortably with portable DAC/amps, dongles and desktop setups, as well as more powerful headphone amps. A power delivery of 125mW into 16 ohms is sufficient to drive the Aeon Core.
DCA spent a long time developing the Aeon Core’s driver stack, utilising a new diaphragm material to enhance efficiency and reliability and deliver a strong cost/performance ratio. The company’s V-Planar technology is applied to the diaphragm’s surface to reduce distortion, enhance dynamic performance and optimise frequency response.
Dan Clark – DCA’s founder and chief engineer – uses the Harman Curve as a key reference when tuning new headphone designs. The Harman Curve was developed by Harman International as an ‘ideal’ frequency response profile, resulting from landmark research into listener satisfaction with a large, diverse population sample and extensive double-blind listening tests.
However, since Dr. Sean Olive, Todd Welti and their team began developing the Harman Curve in 2012, the technology used for measuring headphones has evolved. Specifically, a more recent microphone – the GRAS RA0402 – has become universal in headphone development, alongside GRAS pinnae (models of the outer part of the human ear) that are different in shape and consistency to the ones used by Olive and Welti. As a result, the original Harman Curve measurement system and lab gear that is now standard across the industry record different frequency responses when measuring the same headphones.
This has reportedly led to a built-in ‘error’ in the Harman Curve; headphones developed with now-standard test equipment may not be faithful to the intended result when using the original data as their reference. In 2025, Dan Clark worked with Olive to develop a corrected version of the over-ear target, using the original hardware as a reference point to produce an updated curve that translates accurately to current measurement systems. The Aeon Core are the first headphones developed using this new curve.
The effect is a tuning that is subtly but meaningfully different from prior Aeon models: a slightly leaner upper bass, a gently lifted lower midrange and a softer upper midrange. Vocals sit forward without hardness, acoustic instruments retain body and weight and bass is taut and present without overstatement.
Sporting a new aluminium and dark wood aesthetic, the Aeon Core retains physical elements that have defined the line including DCA’s signature Aeon earpads, a lightweight titanium headband and self-adjusting suspension strap.
The fit is said to be comfortable and fatigue-free across extended listening sessions, aided by a weight of 440g.
Shipping commenced this week (14th June) from DCA’s facility in San Diego, California. They come with a detachable cable, terminated with the customer’s choice of connector – balanced 4.4mm, 4-pin XLR or 6.35/3.5mm.
The Aeon Core is brought to the UK by Electromod, DCA’s UK distributor, with stock expected at selected retailers from early July at an RRP of £920 inc. VAT.
Customers who purchase the headphones from an official UK stockist benefit from a two-year warranty and UK-based tech and servicing support.
