Campfire Audio Hybrid-Design Earphones

Blending the Best

Bringing together two prominent driver types, hybrid design IEMs combine different driver technologies to leverage and blend their contrasting strengths and allow them to elevate one another's performance.

At Campfire, our hybrid IEMs combine dynamic drivers and balanced armatures to allow for the incredible impact and texture that DDs are known for, with the amazing speed and resolution of BAs in the upper registers. Using our Phase Harmony Engineering to dedicate individual drivers to specific segments of the frequency spectrum, we are able to assign the drivers to the range that best suits their performance.

There are many challenges when it comes to marrying these various technologies; tackling driver sensitivity, frequency crossover, internal geometries, and more. Our years of experience, skilled engineering team, and 15 hybrid IEMs (and counting) give us deep insight into creating high performance, cohesive, and varied sonic profiles.

Power & Impact: Dynamic Drivers

Applied in our hybrid IEMs, our range of custom dynamic drivers are deployed to lay a low-frequency foundation to your earphone's performance. With larger diaphragms, our dynamic drivers lend themselves well to creating impact and physicality in bass frequencies.

Combining a range of driver sizes, diaphragm materials, and incorporating custom damping values, tuning chambers, and other acoustic engineering, we're able to create a variety of textures, intensities, and experiences to our hybrid IEM's bass perrformance.

Changing the Dynamic: Diaphragm Materials and Driver Size

Campfire Audio has a long history of implementing new and exciting dynamic driver technologies.

Our first hybrid IEM, Dorado, was launched in 2016 and the first to feature a Beryllium PVD diaphragm. Later, we introduced our revolutionary Amorphous Diamond-Like Carbon (ADLC) 10mm dynamic driver; which became a long-standing, high-performance driver featured in many of our flagship, hybrid IEMs.

The recent introduction of our Dual-Magnet Dynamic Driver has been integral to the success of Bonneville & Black Star within our line of hybrid IEMs.

Campfire has additionally implemented LCP (liquid crystal polymer) and biocellulose, and nano-titanium diaphragms across our range of dynamic drivers.

These drivers have all spanned a range of diameters, lending themselves to different timbres and frequency ranges; including 6mm, 8mm, 8.5mm, and 10mm)

Striking a Balance: Hybrid IEMs and Balanced Armature Technology

Where dynamic drivers are large and capable of creating rich, full sound, but face challenges with speed and overall impulse response, balanced armatures are small, and lightning fast, lending them to incredible detail reproduction, precsion, and overall resolution.

This lends balanced armatures to being a perfect companion to dynamic drivers, creating a combination of rich emotional content, and crisp, technical prowess.

There from the Beginning

Developed in the 1950s for use in hearing aids, balanced armatures have been involved in IEM design since their inception. Similarly, balanced armature technology has been integral to our line of earphones. Campfire has implemented a wide range of custom balanced armatures in a variety of sizes and combinations to span a wide spectrum of tuning profiles across our hyrbid IEM lineage.
