Outstanding headphone

Crutchfield Customer Review (What's this?)

Super nice. Neutral sound, with some bass. Or a neutral "stereo sound". Its very detailed to the author. The Aeon C is more linear sounding compared to the Ether C. Both sound amazing and have there own use. Very comfortable and well made. Cables are really great too. Recommend a outlet amplifier for superior performance.

Pros: light weight, comfortable, beautiful sound. Case and cloth included.

Product Research


Overview: The MrSpeakers Ether C Flow is an over-ear, closed back planar magnetic headphone. These audiophile-grade headphones are precision machined and crafted to deliver superb performance throughout the extended frequency range. For best performance, it is recommended that you use a high-quality headphone amplifier with the headphones.

Planar Magnetic Drivers: The Ether C Flow uses planar magnetic drivers which deliver much better performance over standard dynamic drivers. Bass response is full and strong, while the sound stage and imaging are more defined. With Ether C Flow's closed back design, there is deeper bass and better attenuation of external noise, compared to the open-back Ether Flow.

Construction: The Ether C Flow headphones features a black anodized milled aluminum main ear cups to house the large 2-3/4" x 1-3/4" planar magnetic drivers. Two thin NiTinol memory metal bands hold the ear cups together, and provides the right amount of pressure on the head. NiTinol is Nickel Titanium metal alloy that returns to its original shape, even after being severely bent. Soft lambskin leather is used for the headband and the ear pads for ultimate comfort. The closed-back Ether C Flow features a carbon fiber exterior.

Ear Pads: The soft memory foam ear pads provide comfort for extended listening sessions. The inside cutouts for your ears are rectangular (1-5/8" wide x 2-5/8" high), matching the positioning of the planar magnetic drivers, and the pads are angled for a more secure and comfortable fit.

DUM Cable: The MrSpeakers Ether C Flow comes with the 6' detachable DUM (Distinctly Un-Magical) cable. The fabric-covered Y-type cable features 4-pin connectors on the headphone end and a sturdy 1/4" plug on the other (device) end.

Storage Case: The headphones come with a brown molded, hard-side, clam-shell case for storing your headphones (with the cables removed). The case has a 3-sided zippered closure.
