Overview
Key Features
【5-Driver Hybrid Full-Spectrum Acoustic Architecture】 Equipped with dual low-frequency dynamic drivers, dedicated bone conduction subbass enhancer, Knowles balanced armature midrange driver & mini planar treble tweeter, each transducer covers an independent frequency band to eliminate muddy frequency overlap. Delivers flat 20Hz–20kHz studio-quality sound with crystal-clear instrument separation, perfectly tailored for classical scores, film soundtracks, studio mixing and live stage monitoring.
【Hand-poured Twin Starry Night Epoxy Resin Shell, All-day Comfort Fit】 Every earpiece is individually hand-cast with red & blue translucent epoxy embedded with gold foil, forming exclusive one-of-a-kind star textures. The ergonomic triangular contour comes with 9 pairs of silicone ear tips in multiple sizes and colors to fit all ear canal sizes and allow for customizable styling. The soft ear tips create a secure, fatigue-free acoustic seal for all-day listening, delivering outstanding passive noise isolation to block ambient distractions without batteries or active noise cancellation.
【Upgradable 6N OCC Single Crystal Litz Cable, Wide Device Compatibility】 Detachable braided Litz cable built with 99.9999% ultra-high purity 6N single crystal copper suppresses skin effect and signal loss to retain full treble detail. Standard 3.5mm stereo plug works with laptops, audio interfaces, DAPs and smartphones; the universal 0.78mm 2-pin connector supports aftermarket cable upgrades. A free 3.5mm to USB-C adapter is included for full compatibility with modern Type-C devices.
【Neutral Instrument-First Studio Tuning For Natural Uncolored Audio】 Professionally calibrated flat frequency response balances warm textured bass, transparent unmasked mids and airy extended highs. Bass never overwhelms vocals or string details, while airy treble extension preserves delicate instrumental texture. Tuned exclusively for mixing engineers, podcasters, classical audiophiles and music lovers seeking raw, unaltered studio reference sound.
【Complete Accessory Kit & Factory Calibration】 Includes multi-size silicone ear tips, durable storage case, user manual, and 3.5mm to USB-C adapter. Every C14 undergoes strict factory acoustic calibration testing before shipment to ensure consistent studio-quality sound. Backed by a standard manufacturer warranty against workmanship defects. Ideal for studio monitoring, daily commutes, or as a premium gift for music enthusiasts.

Frequently Asked Questions
What makes the ES-C14's five-driver hybrid setup different from single-driver earbuds?
Each of its five transducers covers an independent frequency band, so dynamic drivers, a bone conduction enhancer, a balanced armature, and a planar tweeter split the work to reduce frequency overlap and muddiness.
Is the ES-C14 tuned for heavy bass or neutral listening?
It uses a neutral, instrument-first studio tuning. Bass is present via dual dynamic drivers and a subbass enhancer, but it's calibrated to avoid overwhelming vocals and string detail rather than to boost lows.
Can I upgrade or replace the cable on the ES-C14?
Yes. The detachable 6N OCC Litz cable uses a universal 0.78mm 2-pin connector, so aftermarket cables are supported. It ships with a 3.5mm plug and a bundled 3.5mm to USB-C adapter.
Will the ES-C14 work with my USB-C phone or laptop?
Yes, through the included 3.5mm to USB-C adapter. The cable natively uses a 3.5mm stereo plug for laptops, audio interfaces, DAPs, and smartphones with a headphone jack.
Does the ES-C14 have active noise cancellation?
No. It relies on passive isolation from the soft silicone ear-tip seal to block ambient sound, working without batteries or active circuitry. Nine tip pairs help you find a secure fit.
Will every ES-C14 look the same as the product photos?
Not exactly. Each shell is hand-cast from red and blue epoxy with gold foil, creating unique star textures, so the exact pattern varies from pair to pair.
