Got my FB 2 today (not pro), updated the pods to 129 (thanks to
@MirageBlader) and yes HWA is working! pods fits well and dosn't fall that easily unless you bang your head on a wall
Audio quality is excellent, no drops in audio. downloaded a Hi-Res audio sample 24 bit/ 96 KHz to check if HWA supports it, noticed that HWA supports max 24 bit/ 48 KHz audio. This means the digital processing is "GOLD" standard ("PLATINUM" standard is the one that supports 24 bit/ 96 KHz) , may be in future we can expect "PLATINUM" standard buds which means quite close to studio quality audio..
in developer mode I see following options:
a) Bluetooth Audio codec: SBC, AAC and HWA
b) BT audio sample rate: 44.1 kHz and 48 kHz
c) BT audio bits per second: 16 and 24 bits per sec
d) BT audio channel mode: stere (mono is greyed out)
e) BT audio HWA playback quality:
optimized for connection quality: 400KB/s
Balanced audio and conn. quality: 500/560 KB/s
Optimized for audio quality: 900 KB/s --> I have this on
f) BT audio HWA latency: low (50-100 ms), mid (150-200 ms) and high(300-400 ms) --> I have low latency on
Bass, mid and highs are excellently tuned. The lowest effective bass frequency is 15 Hz (depends on your ear but for me 15 Hz thump can be felt). No delay between pods
I wished Huawei app could have in-app audio/mic settings like in case of Jabra Elite 65t. To get the best of Audio we can bet on Viper4Android but I have decided not to root my phone for that.
I installed an app called Easy voice recorder pro in which I can set audio source as bluetooth, recording is Mono and format is PCM (0.9 KB/s) and record quality is decent, not crystal clear or crisp, but decent enough. The noise cancellation is pretty much intrusive and noticeable, am yet to check actual call quality, will update later.
I had plans of buying Jabra Evolve 65t but I bought this mainly for HWA High-res audio listening experience. All-to-all I am not disappointed, the case is compact and is light in weight, can be carried in pocket.
I also tried Freebuds 2 on my Ticwatch Pro watch and I was happy with music quality and also no audio drops.
Any other questions feel free to ask..
