14 Balanced Armature Drivers: Multi-Band Precision
Each earpiece in the AFUL Cantor 14BA houses 14 high-quality balanced armature drivers, strategically grouped and tuned to deliver a fully integrated and coherent sound signature across the frequency spectrum.
These drivers are divided into frequency-specific roles:
- Low frequencies benefit from multiple BAs tuned to deliver tight, fast, and punchy bass without the bloat of dynamic drivers.
- Midrange frequencies are rendered with exceptional clarity, making vocals and acoustic instruments shine.
- Highs and ultra-highs sparkle without harshness, thanks to dedicated tweeter units that preserve air and detail.
The result is a reference-grade sound that captures the full complexity of your music—without distortion or fatigue.

Advanced Crossover System for Seamless Integration
With so many drivers on board, proper signal distribution is key. AFUL uses a proprietary multi-way crossover network that divides the frequency ranges accurately and feeds each driver type exactly what it’s designed for.
Unlike simpler crossover systems, the Cantor’s architecture is finely tuned to prevent phase issues, time delays, or overlapping frequencies. This ensures:
- Smooth transitions between bass, mids, and treble
- No artificial colorations in the vocal range
- Consistent tonality at low and high volumes
The result is a soundstage that feels wide, natural, and effortlessly cohesive—ideal for analytical listening or emotional immersion.

Audiophile Tuning for Clarity and Balance
The AFUL Cantor 14BA is tuned with precision, offering a balanced, reference-style signature that favors realism and micro-detail over bass boost or artificial warmth. While it doesn’t exaggerate any frequency range, it offers:
- Fast, tight bass that’s present but not overwhelming
- Forward mids that bring vocals and guitars to life
- Clean treble with excellent air and extension without sibilance
This makes it a great IEM for:
- Studio monitoring and mixing
- Classical, jazz, and acoustic genres
- Technical metal, prog rock, and complex instrumental arrangements
- Audiophiles who prefer neutral with a slight energy in the highs
The Cantor 14BA avoids the scooped-out “V-shaped” signature of many consumer-oriented IEMs and instead offers something mature and technically proficient.

Comfort and Ergonomic Shell Design
Despite housing 14 drivers per side, the Cantor’s shell is surprisingly compact and comfortable. AFUL has sculpted the earpiece to fit naturally in the ear canal, using lightweight materials and ergonomic shaping to ensure:
- Long-term comfort during extended listening sessions
- A snug fit that aids in passive noise isolation
- Minimal pressure points or ear fatigue
The nozzles are angled for optimal insertion depth, and the included multiple ear tip options ensure compatibility with different ear shapes and preferences.
This comfort makes them ideal for stage performers, commuters, and anyone who spends long hours with earphones in.

Detachable Cable and Upgrade Options
The AFUL Cantor 14BA features a detachable cable system, typically using a standard 0.78mm 2-pin connector, allowing you to swap out cables for:
- Balanced sources (2.5mm/4.4mm)
- Bluetooth adapters
- Silver or OCC cable upgrades
- MMCX-to-2-pin converters
This modularity not only extends the lifespan of your IEMs, but also gives you room to fine-tune your setup based on your gear or preferred sound signature.
The included cable is often a high-purity silver-plated copper model—flexible, durable, and sonically transparent.
Build Quality That Matches Its Sound
AFUL has crafted the Cantor 14BA with attention to detail:
- Acrylic or resin shells with high-end polish and artistic faceplates
- Strong, well-aligned connectors that hold securely
- Smooth internal wiring and resonance-optimized cavities
- Minimal driver flex, even under dynamic use
This is not just a functional product—it’s a beautifully constructed piece of audio engineering. Whether you choose the clear resin finish or a custom color faceplate, the aesthetic appeal matches its performance.
