Product Description
We’ve partnered with Dan Clark Audio (formerly MrSpeakers) to improve a remarkable and well-regarded pair of planar open-back headphones. Introducing the Aeon Open X: our take on the Aeon Flow Open.
Optimized Open-Back Performance

In the world of open-back headphones, few models have a reputation to match the Aeon Flow Open from Dan Clark Audio (formerly MrSpeakers). With a naturally appealing sound that’s both warm and punchy, plus excellent power response and ultra-comfortable fit, the Aeon Flow Open is close to perfect—close. To get it even closer, we worked with Dan Clark Audio to create the Aeon Open X. Featuring partially fenestrated earpads and reduced driver dampening, these Drop-exclusive headphones deliver a widened soundstage with the same punch and detail as the original. 

Taking a Fan Favorite Further

How do you make great headphones better? You listen. When creating the Aeon Open X, we listened closely to its predecessor and input from our community of audiophiles. Experimenting with the dampening paper covering the drivers, we opted to use fewer plys, creating a more even tone. To add a bit more air and extension, we used the same partially fenestrated earpads featured on the Aeon Flow 2, minimizing sound reflection back into the ear. The result? Wider and clearer audio.

The Dan Clark Audio Difference

Dan Clark is a renowned audio engineer who has been working in the high-end audio market for more than 20 years. In founding Dan Clark Audio, his mission was simple: to create high-quality headphones that allow listeners to experience incredible audio and nothing less. To that end, headphones should also deliver exceptional comfort, because—as Dan says—uncomfortable headphones “get in the way of musical enjoyment the same way a terrible seat at a concert venue detracts from a live performance.” With a history as a community modder, Dan strives for continual improvement and makes upgrades available whenever possible.

Optional Drop + THX AAA™ 789 Linear Amplifier

Announced at CES 2018, the Drop + THX Achromatic Audio Amplifier (THX AAA™) 789 is a linear bipolar amplifier with feed-forward error correction. It’s designed for objectivists who appreciate an incredibly clean, transparent amp—the sought-after “wire with gain” whose amplification is wholly uncolored by a sound of its own. Made in collaboration with THX Ltd., it features the company’s groundbreaking THX AAA and feed-forward topology, which reduce distortion by 20 to 40 dB for realistic, fatigue-free listening. In fact, this bridged-output amp’s performance figures speak for themselves: It’s powerful (2 x 6W at 32 ohms) and quiet (136 dB SNR) with a record-low THD of -140 dB at 300 ohms, 100 mW. That’s four times the power of the Objective 2 amp, for example, with far less distortion.
