Hybrid in-ear headphonesDD subwoofer + two BA drivers + two microplanar tweetersScientifically based IEF 2025 tuning: Precisely tuned by Crinacle to the IEF 2025 curve for speaker-like balance and true tonal neutrality3D-printed acoustic waveguide: Resin-filled shell with internal 3D-printed chambers ensures phase-accurate crossover and acoustic precisionErgonomic design with modular cable: Comfort-oriented shell with universal fit and interchangeable 3.5 mm/4.4 mm plugs for flexibility and upgradeabilityA new beginningDaybreak is CrinEar's first mass-produced IEM product and a bold step forward in design, tuning, and execution.Developed to push the boundaries of acoustic precision and performance, Daybreak sets new standards in the ever-evolving world of in-ear monitors.Experience reference-grade audio quality with the CrinEar Daybreak, Crinacle's first mass-produced tribrid IEM.With the Daybreak, CrinEar presents a pair of in-ear monitors that combine five drivers per side in a hybrid configuration to get the best out of each technology.Designed for neutral sound reproduction with a comfortable listening experience, they combine an advanced crossover design with rigorous tuning methodology and optimized wearing comfort.The result is earphones that are tailor-made for long listening sessions, minimizing both auditory and physical fatigue.Hybrid 5-driver designThe CrinEar Daybreak features five drivers per earphone, utilizing different technologies to ensure optimal coverage of the entire audio spectrum.A dynamic 10 mm driver provides bass with extended and controlled reproduction. Two balanced armature transducers ensure precise and detailed midrange reproduction.Finally, two latest-generation planar magnetic tweeters provide excellent high-frequency reproduction.IEF Preference 2025 curve as a guideline The acoustic development of the Daybreak was based on the renowned Brüel & Kjær Type 5128 simulator, which ensures extreme precision in reproducing the target curve.The tuning has been carefully calibrated to match the IEF Preference 2025 curve as closely as possible, which is known for providing a natural, balanced, and pleasant sound during long listening sessions.The result is a neutral sound with a slight warmth in the bass range, very neutral mids, and detailed but never shrill highs.3D printing and custom crossoverThe Daybreak's housing is made of 3D-printed acrylic resin, a process that allows for extreme precision in shaping the internal acoustic channels.Thanks to this technology, CrinEar was able to develop a complex crossover that is perfectly matched to the characteristics of each individual driver.This approach ensures optimal frequency distribution, a smooth transition between the individual bands, and a consistency of sound that is rarely achieved in this price range.Wearing comfort Special attention has been paid to the ergonomics of the Daybreak earphones: their contoured shape fits naturally in the ear and ensures a secure fit without uncomfortable pressure points.The acoustic nozzle, less than 6 mm in diameter, offers an excellent compromise between durability, isolation, and comfort, ensuring a comfortable fit even during long listening sessions.Detachable cable with replaceable connector The Daybreak comes with a detachable silver-plated copper cable that ensures optimal conductivity for lossless signal transmission. It features interchangeable connectors, allowing you to easily switch between an unbalanced 3.5 mm jack output and a balanced 4.4 mm jack output depending on your equipment and preferences.

The Reference was developed based on state-of-the-art acoustic research and is designed to be the world’s flattest IEM on the market*, with a focus on transparency, linearity, and repeatable accuracy.*Based on compliance with the population-averaged diffuse-field response (JM-1) with a slope of -1 dB/octave, measured using standard equipment in accordance with ITU-T P.57 Type 4.3Perceived linearityWhile the Reference is designed to achieve objective neutrality on paper, its tuning has been further refined to deliver true perceived linearity. Recognizing the inherent differences between in-ear listening and far-field speaker systems, a subtle boost of approximately 2 dB is applied to the low frequencies to restore the sense of physicality often associated with high-end studio monitors in acoustically treated rooms.This careful adjustment bridges the gap between measurement accuracy and the real listening experience, ensuring that the Reference not only measures flat but also sounds naturally balanced and lifelike in practice.Tuned for the studio – Built for the stageThe CrinEar Reference was developed as a true monitoring tool and delivers realistic, faithful reproduction for critical listening and mix evaluation.With reliable sound balance, precise clarity in the midrange, and controlled low-frequency response, the Reference is designed to be your portable studio monitor, ensuring mixes can be implemented confidently across any room.HODWS ArchitectureThe bass frequencies are handled by a specially developed system featuring two 10-mm dynamic drivers arranged in a horizontally opposed configuration. This Horizontally-Opposed Dual Woofer System (HODWS) allows the two woofers to share their mechanical load, resulting in the following benefits:-Reduced stress on individual diaphragms-Improved bass linearity and control-Improved energy efficiency-More powerful and precise bass reproductionUltimately, this ensures realistic bass reproduction with a flat frequency response. Because “flat bass” should not mean “no bass.”Sonion and Knowles driversMid and high frequencies are reproduced by a carefully engineered arrangement of two Sonion midrange drivers and a single Knowles super tweeter. Each driver is hand-selected to meet our strict tuning targets and then equipped with the most efficient crossover network. CNC-milled aluminum housingAll of the Reference’s drivers are housed in a solid aluminum enclosure precision-machined using a 5-axis CNC process. The contoured, virtually custom-tailored geometry offers:-High structural rigidity to suppress enclosure resonance-Durability that withstands professional use-A secure, comfortable fit, optimized for extended listening sessionsHigh-quality modular cableThe package includes a high-quality, detachable cable with a replaceable connector system:3.5 mm single-ended for universal compatibility4.4 mm balanced for reduced crosstalk and improved channel separationEnjoy flexibility with portable and stationary sources, in both consumer and professional settings, without compromising signal quality.Technical SpecificationsDriver configuration: 2 x 10 mm DD (HODWS) + 3BAImpedance: 16 Ω at 1 kHzSensitivity: 104 dB/mW at 1 kHzFrequency range: 2 Hz to 44,000 HzOpening width: 6.0 mm (lip)Cable material: silver-plated copperIncluded in deliveryS/M/L silicone ear tips (Standard bore)S/M/L silicone ear tips (Small bore)XS/S/M/L silicone ear tips (Wide bore)M foam ear tipsFaux leather case with zipperSPC cable with interchangeable 3.5 mm single-ended and 4.4 mm balanced plugs
