SPEC:
MOONDROP Blessing 2 In-Ear Headphones
Impedance: 22 Ω @ 1kHz (± 15%)
Unit configuration:  1DD & 4 BA each side
Frequency response range: 9-37KHz
(1 / 4-inch free-field microphone, -3dB)
Treble unit: Knowles SWFK
Midrange; Softears D-MID-A
Bass: 10mm paper cone diaphragm coil
Effective frequency response: 20-20KHZ
(EC60318-4)
Quality control range: ± 1dB @ 1kHz

Shell technology: 3D printing of imported medical resin


Description:


1 DD + 4BA configuration •Hybrid three frequency division
The physical band-pass and low-pass filtering of the sound duct structure relying on 3D printing to form a hybrid three-frequency structure, which is divided by the RC power frequency division.
Dual Knowles’ SWFK high-frequency balanced armature unit is responsible for high-frequency.
A pair of exclusive custom IF units are for mid-frequency (to achieve VDSF Target Frequency.
Response)
A 10mm dynamic coil unit of a paper cone composite diaphragm is for low-frequency.
All for the transparent sounds with deep bass, middle pitch, and sweet treble.


Scientifically effective and unpretentious configuration
The configuration of 1 DD and 4BA efficiently utilizes the acoustic characteristics of dynamic and armature hybrid. Unlike the blind stacking together, Blessing2's configuration is simple, reasonable, and efficient. A custom full-frequency composite balanced armature is responsible for the mid-frequency, and it is used in the 500Hz-80004 frequency band that meets the VDSF Target Response in conjunction with the circuit and filtering conditions, which guarantees the quality and dynamic density. For the high-frequency, this earphone adopts the American Knowles SWFK with low distortion and excellent high-frequency bandwidth to match the mid-frequency sensitivity. With excellent low frequency response, quality index and hearing sense, 10mm diameter paper cone diaphragm dynamic coil unit is used for low-frequency, and its use efficiency at low frequency is much higher than any of them.


3D printed high-precision physical filtering sound duct structure
The frequency division method for Blessing 2 includes physical band-pass filtering and low-pass filtering. Band-pass filtering is used to adjust the response range of the low frequency and mid-frequency, and low-pass filtering is used to limit the Q value of the mid-frequency and high -frequency.

With complex structure, its design architecture is effective. To achieve the ideal index, the complex sound conduit structure requires thousands of experiments and modifications, and considerable accuracy



Working with Master 3D Printing Supplier
In order to accurately achieve the complex physical filtering internal structure of Blessing2 and avoid the acoustic structure error, an ultra-high-precision 3D printing process is needed.
So we cooperate with the well-known 3D printing supplier "Heygears Technology" to apply its mature high-precision DLP-3D printing technology and use imported medical-grade UV resin to produce high precision, high transparency, high hardness, and accurate complex cavity.

Precision CNC stainless steel cover

Blessing2's cover is made of medical grade stainless steel, which is sliced by precision CNC, engraved with brushing process, and 3D printed transparent shells. All of this procedure constitute a work of art with rich industrial beauty.

One side of Blessing 2 is laser engraved with the "Blessing2" logo, while the other retains the unpainted stainless steel brushed texture.

The high adhesion of brushed stainless steel provides a chance for customer to DIY on it to show their unique personality

Not only that, you can also be creative and do various things on it, such as laser carving

You can even use it to sharpen your nails.



Sweet treble, middle pitch, deep bass• Transparent and revive
The advantage of the "physical filtering + RC filtering" hybrid three-frequency architecture lies in precisely controlling the response of each unit, so that each unit can play an ideal level in its operating frequency band, and then achieve the frequency response index in accordance with the VDSF Target Response For Blessing2, it presents the sound quality that can accurately restore the information contained in the recording.
