Airmotiv GR1 Headphones

The Airmotiv GR1 headphones utilize cutting-edge graphene infusion technology to deliver an exceptionally musical and engaging listening experience. Free of listening fatigue and non-linearities, our graphene reinforced, low mass, 50 mm polycarbonate drivers have crystal clear highs and remarkably lifelike midrange. Bass is powerful, controlled, and extended. The soundstage is open and extremely natural. Equally as important, they're comfortable enough to wear all day long and built so well you'll be able to enjoy the GR-1s for many years.

Sound Quality: Always First

At Emotiva, we think that sound quality always comes first. It's true for headphones, as well as all of our gear. While our Airmotiv GR1 headphones utilize cutting edge technology and superior construction, we consider their most important feature to be their fantastic sound. Clean, clear, detailed, smooth, punchy, but never muddy. Their semi-aperiodic earcup grills offer a cross between an open and closed headphone design - the best of both worlds. They partially isolate the listener from the outside world while providing an incredibly smooth, natural, and open sound field. We think our Airmotiv GR1's sound the way a pair of headphones should sound - like music.

Quality Design

Our replaceable high-quality perforated vegan leather earpads are attached with a rigid mounting ring; it latches in to hold them firmly in place but removes easily if they ever need to be replaced. Premium, ergonomically contoured memory foam inserts make extended listening a pleasure. The headband is solid metal, with just the right amount of spring, and real ball bearing metal click-detents ensure that it stays put when you adjust it not only today, but years from now. We've included a beautiful 2 meter, super-flexible, noise-free, cloth-covered headphone cable. Internal construction uses pure multi-strand OFC copper and attaches with standard 2.5mm audio connectors at the earcups, making it easy to swap the cable later for a balanced one or a third-party upgrade. Of course, all electrical contact surfaces feature heavy gold plating, and the connector bodies themselves are all machined metal.

What You Need To Know About Graphene

Graphene is a high-tech type of carbon with a unique atomic structure that can enhance the strength and improve materials' dynamic characteristics in specific applications. Our Airmotiv GR1 headphones use a newly developed high-tech diaphragm consisting of a very thin polycarbonate membrane with a specially applied and deposited graphene lattice layer fused to both sides of it. The result is the ideal combination of low mass, controlled stiffness, and improved damping. This diaphragm, along with our low moving mass motor assembly, operates in a carefully designed magnetic system, delivering exceptional clarity, linearity, and low distortion.

Great Sound and Universal Compatibility

• The clear detailed sound of the Airmotiv GR1 ensures that they will sound great with all
  of your high quality audio content.
• Because the GR1 combines low impedance and high efficiency, they’re very easy to
  drive, so they’ll work perfectly with all of your audio gear, from smart phones and
  portable music players to dedicated high-end headphone amps.
• Our earcups use a unique type of semi-aperiodic loading that behaves in a manner
  somewhere between ordinary open and closed back designs. This helps isolate you, but
  allows a more natural and open soundstage.

Cutting Edge Technology

• Ultra-low moving mass diaphragm, comprised of a polycarbonate substrate,
  reinforced on both sides with deposited graphene lattice layers.
