MrSpeakers Ether Open Planar Magnetic Headphones

MrSpeakers

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.

  • ETHER™ is MrSpeakers’ all-new open-backed headphone. We set three goals when we started the ETHER project: sound excellent, be more comfortable than our existing headphones, and have a timeless design.

    So how does it sound? This product has been two years in the making, and many long nights have gone into creating a very detailed yet natural and organic sound. No question: ETHER’s our best work to date. We’re not going to go audiophile and poetic here; no blathering about air and soundstage, or whatever. Reviewers, enthusiasts and owners will do a fairer job than we ever could.  So we’ll just say we love the sound of ETHER and we hope that if you get a chance to hear it you’ll agree ETHER doesn’t totally suck.

    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.

  • NiTinol Headband

    ETHER also uses a NiTinol "memory metal" headband to reduce weight and improve comfort. NiTinol is Nickel-Titanium allow 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, as conceptually illustrated in Figure 1.
