What we think in the Inner Sanctum:

-NOTE- This is our last demo unit open-back Ether, which is in mint condition and has about 250 total hours playing time on it...barely broken in!  Call or email if you would like to come listen to them before buying (and ask if you need a different connector than 1/4", we can probably accommodate you.)


The Ether was MrSpeakers' original all-out assault on the state-of-the-art and the first all-original design they ever created (after starting out as headphone modders). It is an open-back planar magnetic headphone that rivals or bests any other headphone in its price class (in our humble opinions). While the crown has been passed to the newer Ether Flow, the original Ether is still a world-class performer.

We have been listening to the Ether with a variety of amplification and source components and are blown away.  From top to bottom, every octave is masterfully reproduced with a clarity, definition and authority that is unrivaled. Another amazing aspect of the Ether is its comfort. You will be able to wear these lightweight beauties for hours with no discomfort or fatigue.

Once again, Dan Clark has crafted a headphone that shames others in its price class and beyond.  Call us to arrange an audition and hear for yourself just how amazing your music can sound.

Take note - Ethers are so revealing that you will want to make sure you have top-flight amplification and source components to go with them.  The Ether offers a clear reflection of the electronics and cables being used to drive them, so you can find the perfect match to put you in audio bliss.

From the manufacturer:

On the comfort front, ETHER weighs in at 370 grams (13.1 oz) making it the lightest full-size planar on the market. To cut weight without sacrificing performance we invented an industry-first headband made of NiTinol “memory metal.”  NiTinol is super-light and ultra-cool because it’s very flexible for a great fit with minimal clamp.   We also designed a new flat ear pad that reduces the size of the headphone, provides a great seal, and since it’s made from our signature lamb-leather, can be worn for long sessions without fatique.

We think it looks pretty nice, too.

So 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.

We love ETHER and if you try it we hope you’ll enjoy it too. On behalf of the team, we look forward to hearing your impressions.


MrSpeakers' ETHER headphone is an all-new design that makes use of several technology and manufacturing innovations to improve performance.

ETHER is built around MrSpeakers designed single-ended planar driver. To optimize performance the planar 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.
