In honor of the Multiverse III music festival held in Sheffield, UK, Campfire Audio has unveiled their latest limited edition in-ear headphones, the Axion Multiverse III. This model marks a significant milestone as it features the brand's first-ever full-size dynamic silicon driver, pushing the boundaries of compact audio technology.
The Axion Multiverse III boasts a custom-designed full-range silicon dynamic driver, promising exceptional sound quality across the entire frequency spectrum.

On the technical front, these in-ear monitors cover a frequency range from an impressive 5 Hz to 20 kHz. With a sensitivity of 94 dB (1 kHz, 135.8 mV RMS) and an impedance of 16.7 Ohms, they are designed to be easily driven by a wide range of devices. The harmonic distortion is kept below 0.5%, ensuring a clean and accurate sound reproduction.
Included with the Axion Multiverse III is a new cable featuring a built-in high-resolution DAC based on the Conexant CX31993 chip. This DAC supports up to 32-bit/384 kHz and DSD64/128, ensuring high-quality digital-to-analog conversion. The cable connects via proprietary MMCX connectors and terminates with a USB Type-C connector, making it compatible with modern devices without the need for additional adapters.
Priced at $199, the Axion Multiverse III offers a glimpse into the future of in-ear headphone technology, blending innovative driver design with practical features. It's a fascinating development that showcases Campfire Audio's commitment to pushing the limits of audio engineering.
