Flare Audio, has launched what they believe to be the world’s first ‘fully’ open headphones. The Reference R1, aimed at the pro audio and audiophile market, uses Flare’s new approach to produce distortion free sound, even at full volume, enabling true transfer and transmission of source material.

“Traditional headphone designs are based around two main formats, closed and open backed. Both of these traditional approaches suffer from sound distortions in some way caused by enclosed residual pressure interference (ERPI)” explains Flare Managing Director and R1 creator, Davies Roberts.

“Open back designs distort sound information on the compression stroke of the driver and add asymmetry to the waveform. Closed designs distort sound information on both sides of the waveform. This distortion moves the time domain of frequencies, compressing them into the wrong area of generation by the driver. ERPI inside a closed space creates a spring effect on the driver, which limits and distorts driver movement.”

Roberts says all drivers create sound by placing higher frequencies inside the movement of lower frequencies, i.e. 21Hz is created within the movement of 20Hz, 22Hz within 21Hz and so on. If a driver’s movement is restricted by ERPI the time domain of frequency information is also distorted. Flare describes this driver movement distortion as TDD (Time Domain Distortion).

In a typical headphone with one or more closed areas, the time domain of information will become disrupted. For example, if there is ERPI behind the driver then there will be reduced backward movement.

With the Reference R1, both of Flare’s patent-pending technologies (Space^TM and Vortex^TM) have been applied to both sides of the driver to create the first ‘fully open’ true infinite baffle headphone that produces distortion free sound.

Flare’s vortex silencing technology spirals around both sides of the 40mm dynamic headphone drivers to remove all enclosed residual pressure interference (ERPI). ERPI is removed without it travelling across the driver or reflecting inside the headphone enclosure, leading to no audible enclosure based standing wave interference.

Balancing pressures between the front and rear sections enables linear driver movement (LDM), which creates total timbre accuracy says the company’s press release.

Space^TM technology reduces enclosure wall vibration through 4 bolts that pull the rear plate and ear pad plates together with a constant compressive force on the DSV (dual sided vortex) disc. Space technology allows the use of lightweight materials to be used in the DSV disc whilst maintaining the structural strength of more rigid materials.

Vortex^TM technology removes residual air pressure that interferes with the movement of a driver and silences the sound pressure as it escapes into the air. DSV enables linear driver movement providing the listener with a completely natural sound experience. Linear driver movement mimics sound in nature creating highly accurate timbre, phase response, stereo imaging and 3D sound.

“Flare Reference R1 is a completely new listening experience and a vital tool for those wanting to hear everything in sound, without any listening product distortion,” explains Roberts. “Stereo imaging perfectly mimics nature, allowing full 360-degree image placement. Reverb tails and instrument distortion become highly detailed, allowing producers and engineers to have a tool to rely on to perfect their art. We believe the Reference R1 sets a new standard in personal sound listening for both professionals and audiophiles.”

The Reference R1’s are now available for pre-order direct from Flare at a special introductory price of £499 inc VAT.
