Solid-body Custom-fit reference earphones from Campfire Audio.

Featuring a patent pending solid body design custom engineered and optimized for you.

Centered around our 10mm Full Range A.D.L.C. Diaphragm Dynamic Driver, Equinox is a reference tool for artists and audiophiles alike.

Each pair is made by hand for an unsurpassed fit and finish. And as always, designed and assembled in Portland, Oregon USA.

Complete Custom Comfort

Flying Coast to Coast or Performing On-Stage; This is a great fit!

Hours of listening pleasure without fatigue. We offer two custom-fit style options; Audiophile Fit and Artist Fit.

Our Audiophile Fit offers a shallow seal depth without the unnecessary added length of traditional in-ear monitors for the stage. This fit is comfortable and is easy to enjoy wearing in a wide variety of conditions and locations. From a daily work commute to a studio mix-down, this is a great fit style for everyday use.

Our Artist Fit offers a more traditional seal depth to ensure the necessary sonic isolation and added security you need for demanding on-stage performances. Extending into the ear canal, this fit style is excellent for the professional musician.

Solid-Body Design

Simple. Solid. Sonically Superb.

Unique to Campfire Audio Custom-fit earphones is our patent-pending Solid Body earphone design.

Each earphone begins with an impression of your ear. This impression is scanned into our system. Though our signature process, we manipulate the interior acoustic chambers of the Equinox design; arranging them in optimal position inside the shape of the impression. This also allows us the opportunity to optimize the performance of the earphone for your ear. This results in a better sounding earphone. Fewer moving parts also means a more reliable earphone over the life of ownership. Equinox is designed to be an audio tool and it will do so for years even in the most demanding conditions.

Powerful Performance

Deep Bass. Soaring Highs. Natural Presentation.

Using our 10mm full range A.D.L.C. diaphragm dynamic driver as our foundation, we created a custom fit earphone that is something sonically unique and a powerful performer.

With a custom fit and our ‘Polarity Tuned’ acoustic chamber design, Equinox successfully captures the natural musical presentation that only a single full-range high-quality driver can.
Without the complications of cross-overs or competing drivers, our 10mm DD is able to shine across genre. On-Stage performers love the punchy, realistic bass response many have never heard before from an In-Ear Monitor. Audiophiles love the unrivaled coherence of a single driver for Opera, Symphony, and Jazz. This is an easy listening earphone at it’s finest.

Exceptional Earphones

Exquisite Fit and Finish

Equinox features a meticulously buffed and hand-polished finish. The wonderfully smooth earphone body conforms comfortably to your individual ear shape; engineered to your anatomy.

Equinox is completed with a polished stainless steel cap. This cap serves the dual purposes of both protecting the sensitive internal components of the earphone and securely fastening the MMCX connector to the earphone’s body. This ensures a reliable and lasting connection to the earphone. It also regulates the airflow both in front of and behind the driver.

Polarity Tuned Chamber

3D printed acoustically optimized chambers

Campfire's new solid body design provides optimized acoustic performance by incorporating the tuning chambers of the earphone directly into the final earphone print. Our Polarity Tuned Chamber allows us to optimize the sonic performance of our dynamic drivers. Deploying particular volume cavities, both in front of and behind our dynamic driver, we can pull bigger sounds from smaller drivers. This also gives us the ability, in the case of hybrid designs, to specifically target the driver performance. Close attention to detail is critical to delivering you the superior musical experience. Solstice features an acoustically optimized interior model that allows each driver to deliver the very best sound quality. When heard together, the drivers offer a seamless musical experience as a result of this process.
