Recently bought this one and upgraded to v1 at once but when using kz zs10 with full volume on both phone and btr3 is like 10%. Already using HWA on Huawei honor 8x. BT connection is not good as well. It's only good when using fiio music app with HWA but connection always drop even at close range.
Quick fix, remove fiio music app then BT unpair, reboot phone, after that, BT pair again. Never installed music app. HWA(LHDC) is kinda far from LDAC in terms of software maturity, IMHO. Setting for optimized audio quality results to stuttering from time to time even at side by side. Suggest to keep at adaptive bit rate. See attached screenshot.
Fiio BTR3 is turning my GMP 8.35D Mobile to a pair very capable BT headphones. Sound quality (using aptx HD) is similar to my LG V20's built-in Sabre DAC.
The V20's built in Sabre DAC is a touch more dynamic than the BTR3 aptx HD when playing 320K MP3 from Google Play Music. The V20 has more advantage on seperation and resolution if playing 16bit FLAC. The comparison was done in quiet indoor environment. I bet one would not be able to tell difference in less quiet outdoor environment
Mr. FiiO, there is something that you should know about designing an equalizer: A good equalizer must include sliders at 100 Hz, 1000 Hz and 10,000 Hz. 100 Hz is the frequency of punchy bass. For example, to increase the slam of electronic music or any bass notes without affecting the middle frequencies at the same time, that is the best frequency to raise with an equalizer. That is the tightest and punchiest bass frequency. 1000 Hz (1 kHz) is the frequency of voices. If you want to bring vocals forward while keeping the bass and treble sweet (without much middle frequency glare), that is the best frequency to raise with an equalizer. 10,000 Hz (10 kHz) is the frequency of sweet treble. If you want to increase the sweetest treble without increasing treble harshness and high frequency glare, that is the right frequency to raise with an equalizer. It took me several years doing live sound to get this knowledge about equalization. Many people that design equalization software, don't know this. And when the number of bands is limited, they don't include all 3 of these frequencies.
I dont know about huawei phones, but google included LDAC in Android ever since 8, so you should have LDAC support, and if so, use it. I read about HWA, and its really inferior to LDAC in all ways. Technically, its has a narrower bandwidth than LDAc (ldac is wider by 90khz) and the software and coding that Sony has developed into LDAc over the years, being an expert company in anything Audio, makes it far superior to whatever Huawei rushed (and most probably copied from LDAC coding) to the market. I've read a lot of people complaining about HWA constant cutouts, while LDAC is very stable even though it gives you a wider bandwidth.
I think you meant to direct this to @lordaine. Fwiw, I use LDAC on the BT receiver that I have (not the BTR3).
