Customer Review Summary
Introduction to the Dan Clark Audio AEON 2 Open-Back
Released in March 2020, the Dan Clark Audio AEON 2 Open-Back headphones offer an over-ear, open-back design with planar magnetic drivers. Priced at £739, they target discerning audiophiles seeking detailed sound reproduction combined with lightweight construction and practical portability.
Design and Build
The AEON 2 Open-Back features a circumaural fit with a metal and imitation leather headband and faux leather ear pads. Weighing 327 grams without the cable, these headphones remain light for extended sessions. The set includes a 1.8-metre dual-entry cable with 3.5 mm and 6.3 mm connectors and a compact carrying case, enabling convenient transport.
The headphones fold into a small case, a notable convenience for storage and travel. Although the ear cups create substantial isolation despite being open-back, the design leans towards semi-open characteristics rather than truly open. One minor downside noted is the lack of a ratcheted headband adjustment, which occasionally causes the band to slip, although the overall fit is comfortable for long listening periods.
Sound Quality
The AEON 2 Open-Back delivers a smooth, warm sound signature. The bass response is elevated relative to many reference models, extending into the lower midrange around 200-400 Hz, which thickens male vocals noticeably. This bass warmth may appeal to those who prefer a less clinical, more inviting sound rather than absolute neutrality.
Mid frequencies, especially upper mids and presence regions, experience a degree of attenuation. Vocals and speech can feel less lively and somewhat muted. Treble frequencies between 6 kHz and 10 kHz remain present yet lack brightness, contributing to an overall darker tonal balance.
This tonal emphasis means the headphones do not excel in raw linearity but excel in comfort for extended listening, as the sound avoids sharpness or sibilance. Notably, the quick transient response inherent to planar magnetic drivers ensures that details emerge cleanly without fatigue.
Power Requirements and Amplification
With a low impedance rating of 13 Ohms and a sensitivity of 92 dB/mW, the AEON 2 Open-Back can be driven by portable devices. However, the tonal character and dynamic capabilities improve significantly with ample amplification, making a powerful headphone amplifier a worthwhile investment for this model.
Customisation through Equalisation
Critics recommend applying parametric equalization to better balance the sound. Suggested adjustments include:
- +1 dB boost at 64 Hz
- -1.5 dB reduction at 200 Hz
- +1 dB gain from 1000 Hz to 2000 Hz
- +3 dB lift centred around 4000 Hz
These adjustments increase freshness and clarity in the upper midrange and presence regions, counteracting the natural darkness without introducing harshness. The overall sound remains smooth and non-fatiguing.
Comfort and Practicality
Designed for comfort, these headphones are suitable for hours of continuous listening. The padding and lightweight design reduce fatigue. Some users report discomfort caused by the shape of the earcups pressing on the jawline, an aspect likely influenced by individual head and face shape.
The detachable cable is flexible and low noise, adding convenience. The inclusion of both 3.5 mm and 6.3 mm connectors solves compatibility with multiple audio sources. The folding mechanism and compact case aid portability without sacrificing structural integrity.
Comparisons and Final Assessment
Compared to other high-end headphones such as the Focal Clear or Hifiman Arya, the AEON 2 Open-Back is smoother and less sharp in the treble region, favouring long-term listening. It does not strive for absolute clinical neutrality but delivers a balanced, natural presentation with an inviting tonal character.
Its strong points are exceptional build quality, portability, and long-wearing comfort. The sound is engaging once EQ adjustments tailor the frequency response to suit preferences. Those seeking extremely linear or bright headphones may find it too warm or mellow.
Overall, the Dan Clark Audio AEON 2 Open-Back is a sophisticated product worth considering for listeners valuing refined, comfortable sound in an elegantly engineered package. The capability to improve its tonal balance via EQ further broadens its appeal.
