The First-generation Blessing IEM achieved global recognition thanks to its reasonable price, innovative acoustic design and excellent performance. Its successor, Blessing 2, built success with refence sound quality, impeccable details and all-round improved hardware performance, overturning the hybrid headphone rankings and attaining the status of a benchmark products. 

Blessing 3 continues the physical frequency division framework of previous version through the use of state-of-the-art 3D printing. it utilizes a new horizontally-opposed double-dynamic bass driver module that delivers higher dynamic range and lower dynamic nonlinear distortion than previous versions. 

Improved implementation of hybrid frequency division has further optimized the continuity and smoothness of the mid-highs, ensuring ultra-high detail. combined with brand-ew bass module, the result is a full-bodied and authentically natural sound quality. 

The new scientifically-designed horizontally-opposed double dynamic driver module further demonstrates the advantages of the hybrid earphone in bass dynamics. H.O.D.D.D.U.S (Horizontally Opposed Dual Dynamic Drivers Unit System) uses dual 10mm dynamic drivers closely and symmetrically using 3D-printed modular components. The components form a physical band-pass filter comprising two independent filtering structures and damping device, thereby facilitating acoustic adjustment. Thanks to use of dual 10mm dynamic drivers, the maximum sound pressure of Blessing 3 is double that of the previous model, and the diaphragm stroke under the same sound pressure is less than half, giving the bass of Blessing 3 a larger dynamic range and lower nonlinear distortion, and significantly improving the sound quality of lower frequencies. 

The symmetrical H.O.D.D.D.U.S arrangement focuses the magnetic field at the magnetic gap of the two dynamic drivers, leveraging the same principle found in planar magnetic earphones. This not only improves energy conversion efficiency, but also further reduces nonlinear distortion. 

Each of the dual dynamic drivers consists of flexible suspension diaphragm with a paper dome, and the high damping characteristics of the paper dome ensure that the dynamic driver does not generate additional resonance due to split vibration in the mids and high, thus offering a smooth and natural timbre.
