[Pre-order] Campfire Audio Chimera Quad-Brid In-Ear Monitors

2 Years Local Warranty. Pre-order. Stocks will arrive in June 2026. Any mention of "us," "we," "our," etc is by Campfire Audio, not AV One. Chimera marks the next evolution in premium, portable audio performance. Driven by a quad-brid, nine-driver internal architecture blending the best in bone conduction, dynamic driver, balanced armature, and electrostatic driver technologies with Campfire's precision acoustic engineering, Chimera delivers a new level of technical acoustic performance. A NEW LEVEL OF AUDIO PERFORMANCE CHIMERA CHANNELING THE MYTH OF CHIMERA POWER, SPEED, & BALANCE The mythological Chimera is represented by the lion, snake, and goat - it is the spirit and character of this mythological beast that is conveyed in Chimera's astounding sonic reproduction. Bone conduction and our True Glass dynamic drivers deliver tactile, extended, and textured lows, that remain fast and accurate due to the resonant properties of Chimera's magnesium shell and the unique structural character of the glass dynamic driver. Three premium balanced armatures and four electrostatic supertweeters create soaring detail, extension, and air with extraordinary speed and sonic richness. The natural balance of these four technologies is further emphasised through the experienced and careful acoustic treatment to effortlessly juxtapose and blend their strengths. DRIVER SELECTION QUAD-BRID DRIVER ARCHITECTURE 10MM BONE CONDUCTION DRIVER Chimera's 10mm bone conductor is adds powerful resonance and low-frequency impact. Embedded in a custom engineered housing pocket and paired with a magnesium shell to improve conductance and create visceral physicality. 10MM TRUE GLASS DYNAMIC DRIVER Powering low and low/mid frequencies, Chimera features an all-new True Glass DD. Created in partnership with Glass Acoustic Innovations this new dynamic driver uses specialise alkali glass processed for strength and acoustic performance. DUAL DIAPHRAGM BALANCED ARMATURE One of the newest advancements in balanced armature technology; the dual diaphragm BA features two diaphragms connected to a single armature. Working in unison, the diaphragms impart extra sonic richness and weight while still conveying the highly regarded detail and accuracy customary to balanced armatures. TWO HIGH-FREQUENCY BALANCED ARMATURES Two premium balanced armatures work in unison to deliver crisp, accurate, lightning fast high-frequency response; revealing nuance and micro-detail with astounding realism. QUAD ELECTROSTATIC SUPERTWEETERS Extending Chimera’s high frequencies to add shimmer, air, and clarity, these four drivers move with incredible precision to reproduce cymbals, reverb, delay trails, and micro detail. "Chimera's development marks a new horizon for Campfire Audio." - Ken Ball, Founder & Lead Engineer COMPONENTS & TUNING SHELL-EMBEDDED CONDUCTION Engineered to increase surface contact and sonic transmission of Chimera's bone conductor. Chimera's shell features a customised internal 'pocket' that helps maximise surface contact and physical transmission of the bone conduction driver. TARGETED PRESSURE VALVE Backing Chimera's True Glass dynamic driver is rear pressure valve ensuring even air pressure on each side of the diaphragm and allowing greater accuracy and even movement. ACOUSTIC ROUTING AND SPATIAL TUNING Chimera's acoustic routing and spatial engineering underwent over fifty revisions to hone and perfect its powerful sonic signature. Every nuance and detail carefully shapes driver performance to highlight and elevate driver response. HYBRID VINTAGE/CERAMIC CAPACITORS Aiding with Chimera’s driver cohesion is a vintage ceramic-film capacitor chosen specifically for its compatibility and synergy with Chimera's internal architecture. This special component helps to seamlessly blend frequency compartmented driver assemblies and to elevate and unify its sonic presentation. 'MASTER TRACK' TUNING FILTER Layered into Chimera’s nozzle is a final stage tuning damper that adds a cohesive overall tuning adjustment at the last stage of Chimera’s output. EXPERIENCE IN CRAFTSMANSHIP Campfire Audio has designed, engineered, and hand-assembled premium IEMs from our sole location in Portland, Oregon for over a decade. Chimera is meticulously crafted, individually fine tuned, with care and precsion at every step. MATERIALS & BUILD CNC ELECTRO-PLATED PVD MAGNESIUM Chimera's magnesium housing is selected for its unique resonant quality, heightening the physicality and impact of the bone conduction low driver. Engineered with an internal 'pocket' to embedd the BC driver and increase surface contact. CARBON FIBER-BRASS DAMASCUS LID Beautiful, organic, durable, and unique. Layers of brass are folded into carbon fiber and CNC machined to reveal unique shapes and gradients. Each Chimera features its own special fingerprint with no two sets being the same. CUSTOM LID VENTILATION Chimera features a vented housing design that allows for comfortable balance to internal ear pressure. MACHINED BRASS NOZZLE High quality brass is long-lasting and resilient, ensuring you can change ear tips worry free. STANDARD 2-PIN CONNECTORS Chimera uses standard .78mm 2-Pin connectors, using high-quality connector pins and receivers and a recessed installment for added stability and durability. ALO AUDIO VALENCE-6 CABLE ALO Audio returns with a new premium cable SIX HIGH-PURITY CONDUCTORS The Valence-6 cable features six conductors, four high purity copper conductors paired with two 50/50 pure copper/SPC conductors.
