R7 HIFI AMP AptX-HD Ear Amplifier CSR8675 Decoding Headphone Amplifier HiFi Portable Amp

Qualcomm 8675 high-performance Bluetooth receiver chip, using digital methods to solve transmission problems, CR high-sequence blue spear chip, advanced hardware chip and transmission coding, minimize transmission loss.
Qualcomm aptx HDAptX is a digital audio compression algorithm based on sub-band ADPCM (SB-ADPCM) technology. aptxhd audio ensures that Bluetooth devices provide high-definition OD audio. Save sound data through audio transmission.Compared with the previous codec technology, aptxHD can make Bluetooth audio produce sound quality comparable to CD level.
Use analog methods to solve the problem of hearing. The magic sound amp module, with a warm and bile tone, effectively dilutes the dryness of digital audio, making the sound more pleasant and durable
apHD is the advanced encoding method in the Bluetooth transmission scheme so far, and it is also a format that has been tested by the market for stability. It has many advantages such as low packet loss rate, stable transmission and good compatibility, and low system resource occupation.
Whether it is driving big ears with a diameter of up to 50mm or moving iron earplugs with a diameter of only 6mm, it can bring you a pleasant listening experience.
