We are very excited to announce our latest achievement: the HIMALAYA DAC! This is born from our independent research and development.
HIMALAYA is a discrete R2R DAC module that is based on the FPGA algorithm. The combination of its low audio frequency range, out-of-band noise, and low energy consumption making it a perfect match for high-performance audio equipment. The HIMALAYA DAC module supports the standard PCM music signal transmitted by the most common IIS (Integrated Interface of Sound) audio interface, with a maximum resolution of 24Bit.
What can you expect from the HIMALAYA DAC?
The Bluemini R2R Bluetooth Dongle is an update of the original Bluemini that enhances detail and overall performance through the HIMALAYA DAC which features an R2R architecture. A chip composed of an array of resistors with a new algorithm reducing power usage between the chip and peripheral components. As a result, signal-to-noise ratio, total harmonic distortion, and energy consumption are at their most efficient and cost-effective.
Currently compatible with HIFIMAN’s DEVA Pro and R10D headphones – with additional models to be introduced in Q4 ‘21 -- the Bluemini R2R combines true hi-res. audio, out-of-band noise, and low energy consumption to create a high-performance match for in-ear monitors at any price point. The internal HIMALAYA DAC module supports the common PCM signal transmitted by the most common IIS (Integrated Interface of Sound) audio interface, with a maximum 24Bit resolution.
The Bluemini R2R features a battery life of up to eight hours. Its amplifier output of each channel is more than 200mw balanced.
In addition to its wireless attributes, an adaptor cable allows the Bluemini R2R to drive headphones with 3.5mm TRSS (Tip/Ring/Ring/Sleeve) or 4.4mm balanced plugs.
Specifications:
Bluetooth Ver: Bluetooth 5.0
Frequency Response: 20Hz-20KHz
THD+N (DAC Module): 0.0025%
SNR: USB 118dB, Bluetooth 97dB
Battery Life: more than 8 hours
Net Weight: 25g
Codecs: LDAC, aptX-HD, aptX, AAC, SBC
Transmission: Bluetooth/USB Type C
The Bluemini R2R will be available in October 2021. You can find them from our authorized dealers or our official online store.

(but it asks for for e.g equalizer - to be better 
), but it could be 'easly recommended to buy product' if you slighlty improve your implementation of QCC 5125 (as it is capabe of the improvement in USB connection and other related functions).
