Campfire IO
Two balanced armature drivers in Campfire’s remarkable red aluminum shells.
Designed and hand-assembled in Portland, Oregon
Refined in Red
IO (Eye-Oh) presents an all new fun and engaging listening experience. IO’s sound is fast and resolving, with soundstage width and depth. Its unique midrange complements extended high frequencies and articulate bass. The result is impressive fidelity for its class, all with Campfire Audio’s made-in-the USA build quality that rivals higher-end models.
Made by Hand
Based on our classic Campfire Audio profile, IO features a ‘Garnet’ Red Anodized Finish with 24K Gold Plated Screws. An extended length Stainless Steel Spout and Machined Aluminum Body are paired with a custom beryllium / copper insulated round MMCX connectors.
Each earphone is assembled by hand in our workshop in Portland, Oregon by our team of highly skilled craftspeople.
Insides that Count
Driver count has never been as especially important to our designs as the proper selection and implementation of particular drivers. When using more than a single driver, it is as much about the synergy between drivers as it is about any one particular driver.
Using an oversized woofer BA as a foundation and then pairing that with a small tweeter, IO came together. Our Tuned Acoustic Expansion Chamber (T.A.E.C.™) provides that natural and open top-end extension people have come to expect from Campfire Audio earphones.
Smoky Litz
Building from our Silver Plated Copper Litz wire conductors and our popular tangle-resistant twisted cable weave, we’ve added a stylish Smoky jacket to compliment the unique finish of our earphones. A new light-weight molded ear-hook design replaces the memory wire. The result is a light weight cable that is a pleasure to use every day.
Bordeaux Carrying Case
Our exciting new premium ‘Bordeaux’ leather protective zipper case is an update to our standard leather earphone case. Luxurious leather surrounds a substantial and protective rubber barrier that ensures that your earphones will remain safe while in transit. The interior is a dense faux wool lining that preserves the anodized finish of your earphones. Each case is made in Portugal by a small team of skilled crafts people that share our commitment to quality.
