IO is a special earphone. It is a remarkably expressive earphone. It delivers a refined sound that is also exciting.
Many more iterations and unique prototypes were made of Io than any other earphone in Campfire Audio’s line up to date. It was a journey to fine tune the sound and get it right. The result is an earphone that we can proudly stand next our best-known models. We feel confident you will enjoy the result of this effort.
Based on our classic Campfire Audio profile, IO features a ‘Garnet’ Red Anodized Finish with 24K Gold Plated Screws. Stainless Steel Spout and Machined Aluminum Body are paired with a custom beryllium / copper insulated round MMCX connector.
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.
Staying true to the Campfire Audio design philosophy “Less is More” and using fewer, higher quality components is ideal to achieve a more a musical presentation.
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.
New Cable + New Case
Building from our Silver Plated Copper Litz wire conductors and our popular tangle-resistant twisted cable weave, we’ve added a new stylish Smoky jacket to compliment the unique finish of our new line of 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 everyday.
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.
Designed and Assembled in Portland, Oregon USA
Each unit is assembled by hand in our workshop by our small team of highly skilled craftspeople. From driver to body each component part is carefully examined and tested. After each unit is built, it is placed into a pairing pool, where it finds its ideal sonic match.
Premium Custom Connectors
Our custom Beryllium Copper MMCX eliminates the traditional shortcomings of the connection and harnesses all of its benefits. Beryllium Copper provides a robust mating mechanism; one that is typcially made from soft brass. This selection of a harder material extends the life of the component and the earphone.
2 year Warranty
Each unit we make is backed by our 2-Year Limited Product Warranty. Rest assured when you purchased a Campfire Audio earphone, it will be a great ownership experience.
iFi - iDSD Nano Black Label Portable Headphone AMP/DAC
Outputting 10 times more power than a laptop or phone and with a built-in iEMatch, the nano iDSD Black Label can drive any set of headphones or in-ear monitors (IEMs).
Small, lightweight and battery powered, the nano iDSD Black Label can go everywhere you go and it won’t drain your phone’s battery.
It’s Master Quality Authenticated
MQA technology makes hi-res audio streaming a reality and delivers studio master quality audio to your headphones.
It’s High-Resolution Certified
The nano iDSD Black Label is one of the most high-resolution DACs on the market. It supports PCM up to 32/384 kHz and DSD up to 256 times the sample rate of a CD. It is also certified as ‘High-Res Audio’ by the Japan Electronics and Information Technology Industries Association (JEITA) and Japan Audio Society (JAS).
It’s the only portable DAC that lets you choose between the “Listen” (minimum phase Bezier Filter) and “Measure” (linear phase Transient Aligned Filter) options.
The nano iDSD Black Label includes iEMatch to let you choose how much power to apply to your headphones, so it matches sensitive IEMs as well as larger headphones.
What's new with iDSD nano Black Label?
1. The integrated iPurifier adds noise isolation for USB Input.
2. The new OTG ‘A-Type’ USB input links seamlessly with iPhone/smartphones and tablets.
3. The analogue stage features dual-mono design and a dedicated fixed level line out.
4. S-Balanced wiring system for the headphone outputs. This gives the full benefit of balanced outputs when used with headphones/IEMs fitted with balanced wiring with low noise and distortion. Even cuts crosstalk in half for unbalanced headphones.
The nano iDSD Black Label, while very affordable, is packed to the rafters with boutique components.
