What we think in the Inner Sanctum:

The Ether C Flow is MrSpeakers' amazing new top-of-the-line closed-back headphone. Improving on the already-spectacular Ether C required changes to the planar magnetic drivers and the incorporation of a new air-flow system for the magnet structure.

That's a lot of technical engineering and there are plenty more details about all of that below, but what it all translates into for you is: mind-blowing sound.

I could go on and on about the richness and nuance of the sound of both the Ether Flow and the Ether-C Flow, but let me just say that the most common reaction when customers put these on for an audition is a huge smile and a reverent, "Oh wow..."

The Ether C Flow is the finest sounding closed-back headphone we have ever heard. 

If you're anywhere near New York City, we encourage you to contact us and audition these beauties for yourself. Most people have never heard the music they love reproduced by a closed-back headphone in such a magnificent way. If musical enjoyment is a high priority in your life, please consider an audition.

The Ether C Flow does require a good amplifier to sound its best (and we can help you with that as well).

NOTE: ETHER C Flow will sport a new carbon fiber pattern. Photos will be posted when available. While ETHER C has diagonal lines in the carbon weave, ETHER C Flow will have a checkerboard patter so the headphones may be easily distinguished.

 

From the manufacturer:


ETHER Flow is MrSpeakers new flagship open-backed headphone. ETHER Flow uses TrueFlow technology to improve the performance of the critically acclaimed ETHER headphone, delivering sumptuous planar magnetic bass and dynamics, with near-electrostatic resolution.

We set three goals when we started the ETHER project: sound excellent, be more comfortable than our existing headphones, and have a timeless design. Result? The ground-breaking ETHER headphones.

Sound. Many long nights went into creating a very detailed yet natural and organic sound. ETHER headphones are not about having the best bass, mids, or highs, ETHER is about delivering a convincing experience. When you hear live music do you say “wow, what highs” or do you say “Wow, what beautiful vibrato?”

Technology. At the heart of the ETHER headphones is our V-Planar(tm) driver and TrueFlow wave guide technologies. V-Planar technology pleats the driver surface so as to reduce distortion, improve transient response, and extend the frequency range.

Our new ETHER Flow headphones feature TrueFlow technology which smooths the path for air moving into, through, and out of the magnet structure* for greatly reduced distortion and improved dynamics.

Comfort. ETHER headphones are known for their light weight and comfortable clamp, and have a nearly ideal weight distribution, so they can be worn for hours without fatigue. ETHER headphones won’t move around on your head with normal usage, but neither will they leave your jaw and ears aching due to clamping force.

Timeless Design. ETHER is almost entirely metal for durability and sound quality yet its extremely light and comfortable. The team worked overtime to cut weight without sacrificing performance. One solution we found is an industry-first: a NiTinol “memory metal” headband that is super-light and ultra-cool. It delivers just the right level of clamp to keep the phones in place and sealed on most heads, yet it’s remarkably tough and reliable. With it’s light weight, comfortable fit and supple lamb-leather ear pads ETHERs may be worn for long sessions without fatigue.

Why name the headphone ETHER? 19th century physics had no concept of hard vacuum filling to “fill” the vast reaches of space. ETHER was an imaginary substance that filled the voids between the stars. Since a lot of what makes ETHER fun is the sense of space and the deep quiet between the notes, and ETHER was a bit “magical,” it seemed like a nice name.

Innovations:

TrueFlow Aerodynamic Processing

Many types of magnet motors have been used for planars, including large perforated single-pole magnet plates, bar magnets and magnets in trays. While perforated magnetic plates offered excellent airflow they were quite heavy and not terribly efficient for their weight. Bar magnets and magnets in trays are lighter and more efficient, but as audio waves flow around bar magnets they experiences diffraction, which creates distortion and masks some micro-details.

To address this distortion, we have created a smooth insert that can be placed between bar magnets or in the voids in magnets and trays to eliminate diffraction effects.

For magnet/tray motors such as ours, additional smoothing can be accomplished using ear-side wave guides to smooth the transition from the magnet tray, similar to that publicly shared by ZGLISZCZ.

V-Planar Driver Processing

ETHER is built around MrSpeakers designed single-ended planar driver. To optimize performance the drver has been processed using our patent-pending V-Planar technology.

NiTinol Headband

ETHER also uses a NiTinol "memory metal" headband to reduce weight and improve comfort. NiTinol is Nickel-Titanium alloy that is heat-treated to a geometry we set that's ideally mated to our ear-ads to deliver a quality seal with minimal pressure.

V-Planar Driver Processing

Simply stated, a conventional planar driver is usually assumed to move as a flat surface. In reality, this is not possible as the driver substrate is inelastic and “locked” at the boundaries so the driver will move more as an arced surface then a flat plane.

Over the years, different approaches have been developed to address nonlinear planar motion and the artifacts it can cause. Fostex patented their RP technology, used on all their drivers used in our headphones, to reduce panel nonlinearities. Another approach, known as knurling, was patented in 1997 by Bruce Thigpen, founder of Eminent-Technology and pioneer of numerous planar magnetic speaker technologies. We felt it would be possible to improve on the solutions available to date, so we collaborated with Bruce to develop V-Planar knurling technique (we filed for a patent with Bruce as a co-inventor). In simplified form, V-Planar technology addresses nonlinear driver motion by more deeply creasing the diaphragm to increase compliance. Much as pleats allow an accordion to expand and contract without stretching the fabric, the creases in the driver "open" slightly during larger excursions as illustrated in Figure 2. When the driver is processed, the resultant peaks and troughs are deep enough to maintain more of their physical structure even after the driver has been tensioned.

Increasing driver compliance allows it to behave as a more idealized planar surface. With more of the driver surface in linear motion, V-Planar can not only push more air at low frequencies, but with greater acceleration also delivers better dynamics, high-end frequency response, and measurably lower distortion.
