Bluetooth handsfree better quality

Is it somehow posibble to get better audio quality sound when Bluetooth headphones are on hands-free mode? Because when it is only audio, sound qaulity is good (16-bit 44 kHz), but when I need to talk through the microphone, audio quality is changed to poor (16-bit 8 kHz), like old radio. Or I do not hear something through headpones. I have Creative Sound Blaster Jam.



Simple, have set Bluetooth Audio Renderer (Bluetooth stereo audio), for playing, with Bluetooth Audio Input Device (Bluetooth Hands-free audio), for recording?

  • Which bluetooth chipset are you using? Broadcom? CSR? other? and what software you are using to make phone calls?

Short:



No



Long:



There are so called Profiles in Bluetooth, and only one can be active at a time.



A2DP supports one-way HQ audio.



HSP/HFP support two-way audio, but only with very poor quality (HFP 1.6 added mSBC, which is a 16kHz mono codec, before, it was even worse).



(ref http://www.tomshardware.co.uk/answers/id-3399361/bluetooth-headsets-high-quality-audio-microphone-simultaneously.html)



(I added the same answer to both Is it possible to use a bluetooth headset mic while having High quality sound and Bluetooth handsfree better quality because they are found using google.)

    The tomshardware post says there's not enough bandwidth, which is not correct. Bluetooth Classic supports bitrates up to 24 Mbps, which is more than sufficient to carry two stereo streams with a low-latency, CD-quality codec like Opus at around 192 Kbps each. The total bandwidth use would be under 400 Kbps, or 1.6% of the theoretical throughput of Bluetooth Classic. This would allow reliable transmission even with very low signal strength.

It is even more complicated: not only HDP [Hands Free Profile] 1.6 (2011), but even HFP profile 1.7 (2018) considers mSBC optional in both HF [Hands Free] and AG [Audio Gateway - computer, cellphone]. See Table 3.1, page 19.



Also:




Since it is only the AG that knows if wide band speech [mSBC - that 16 kHz sample rate codec] should be used, it should always be the AG that establishes the Synchronous Connection with the required codec.




2.3 d, page 16.



So it is not uncommon that the same HF working perfectly with mSBC under Android AG (e.g. Jabra Elite 65t) fails miserably under Windows 10 with mSBC and all you can do is buing Jabra Evolve 65t for 3x higher price to get the expected result. Or leave Windows for Android...
