Feel The Magnificent True Fidelity Sound

1DD + 4BA Hybrid In-Ear Monitor

Designed·Developed·Manufactured by MOONDROP

1DD+4BA, Hybrid Type Triple Crossover

3D Printed physical band pass&low pass filter tubes, plus Resistor Capacitor crossover forms a "hybrid" triple crossover. Dual SWFK treble is in charge of treble, Mid is handled by our proprietory dual mid BA drivers(to achieve VDSF Target Frequency Response), and a 10mm paper diaphragm dynamic driver for bass. Crispy, sweet high, accurate mid, deep bass response, awaiting its owner.

Effective, Scientific, Ingenuous Driver Deploy

Among all these DD BA hybrids, 1BA+4DD was a kind of singular excellent architechture.Unlike other competitors who just blindly toss drivers into their housing, the structure of Blessing 2 is simply effective and reasonable: Proprietory dual mid driver take the midrange, in synergy with filters and circuits we take the frequencies from 500-8000Hz that comply with our VDSF target response. Knowles SWFK takes care of the treble by its low distortion and excellent high frequency range.(In fact more drivers on this parts usually leads to degraded performance) The low frequencies is produced by a 10mm paper diaphragm which is spectacular on bass response, measurements and subjective hearings. The efficiency of its bass response also outperformed many bass BA drivers.

3D Printed High Acuracy Physical Filter Tube Structure

Blessing 2 's physical filter features a band pass and a low pass filter, band pass is used for altering the response range of dynamic bass and BA mid driver, Low pass filter is used for limiting Q value of mid and high frequancy BA driver. This structure was simple, effective but complex to design&build. This complex structure needs exhaustive experiment and revision, and requires pinpoint accuracy in manufacturing to achieve ideal measurements.

Joint Venture With Acclaimed Manufacturer

In order to accurately manufacture the complex structure of Blessing 2 without any errors we need precise 3D printing like never before. So we  established a joint venture with HeyGears, a well known supplier in the industry to take advantage of their matured DLP-3D printing with medical grade UV resin, producing reliable, accurate complex structure housing in high accuracy, transparency, and of course, rigidity.

CNC Faceplate Done, Precisely

Blessing 2's faceplate was made with medical grade stainless stell under precise CNC milling process, then brushed into what you have seen above. It forms sort of artwork of industrial beauty after assembled with 3D printed transparent housing. One side of Blessing 2 is engraved with "Blessing 2" logo, while the other side remains bare brushed metal with some adhesion with paint, in order to leave space for your own creativity(nail polish, sketches, etc.). Not only that, we also offer custom engraving service upon request(extra fee applies)... It can even polish your nails.

BA-DD Phase Isssue?

Not In Blessing 2

On top of the previous product we designed our triple crossover structure of utilizing both acoustical filter and resistor capacitor filter, perserving the phase consistency throughout most of the audible spectrum while keep every driver working in their respective frequencies. No more hybrid panic issues.

Crispy, Sweet High, Accurate Mid, Deep Bass Response. Transparent, Yet Accurate.

The advantage of triple crossover lies in the accurate control of every driver in their respective range while retain their ideal performance, so they can achieve our VDSF target response and let Blessing 2 restores sound quality of original recording in an accurate way.
