Campfire Audio, who design and build their products in Portland, Oregon, USA, have introduced a new innovation to their dynamic driver design; Polarity Tuned Chamber™.

Campfire told us: “Our 3D printed tuned chambers in front and behind the driver allow us to optimise the performance of our dynamic driver. This opens up the sound and gives the driver an effortless power that must be heard to be appreciated. A balanced armature transducer coupled with our revolutionary TunedAccoustic Expansion Chamber™ (T.A.E.C.) compliments the dynamic driver; seamlessly working in harmony to achieve audio excellence. A single high frequency balanced armature driver discards a traditional ‘tube & damper’ tuning system for our new Tuned Acoustic Expansion Chamber™ (TAEC)”.A 3-D printed chamber provides the acoustic tuning without compression. Camfire produce their earphones in small batches for quality control. The precision machined aluminium housing reduces vibrations that induce sonic distortion. These tough shells extend the life the earphone by offering protection from drops. The shells are machined in Medford Oregon, just a short drive south the Campfire Audio workshop.
Campfire have also introduced a new coating to the earphone market.  “Cerakote is a Polymer-Ceramic Composite coating. The unique formulation used for Cerakote ceramic coating enhances a number of physical performance properties including abrasion/wear resistance, corrosion resistance, chemical resistance, impact strength, and hardness.”

They went on to tell us: “The ergonomic shape of the design offers an easy to wear and comfortable fit.  The hard anodized finish makes for a great looking earphone. It is durable and ready to stand up to demanding daily use. The Polaris’ lightweight design is ideal for all day listening sessions”.
