QC35 II Microphone mixed into headphone signal (firmware issue?)
I have the following:
- QC35 II with 3.1.8 Firmware (latest)
- Win10 fully patched
- (Which is a *very common* Operating system)
- Lenovo t470s with AC 8265 bluetooth module with intel driver version 220.127.116.11 (latest)
- (Which is a *very common* BT module)
Whenever I activate the "Handsfree Telephony" I get the microphone signal mixed into what I get on my ears - that means I get the background noise etc. amplified and fed into my ears. (the exact opposite of "noise cancelling" by the way..)
When I deactivate the service like in the screenshot above, I have no microphone available and can not use the headset to make calls.
I bought this headset to use as a communication device for my laptop and so far it is completely useless.
Retried on Linux (Ubuntu bionic beaver)
I get the same behavior as soon as I switch to HSP/HFP: I can hear background noise that is picked up by the microphone in the headphones, especially my typing.
Retried on Android (Nokia 1 with Android 8.1.0)
I get the same behavior as soon as I make a call, so at the time the device switches from A2DP to HSP/HSF it starts mixing in the microphone signal into the channel that is played back to the ears.
I switched to my Shure RMCE-BT1 headset and it does *not* do that. I don't get the microphone signal mixed into my ears directly.
So it seems the people at shure understand that you don't mix the mic into the playback channel, the people at BOSE don't..
And to be 100% clear - I did not make a call, just activating the HSP/HSF profile is enough to get this behavior.
I am very disappointed in BOSE, how can anyone have the idea it would be cool to mix surrounding noise into the audio output of a *noise cancelling* headset - that's just braindead.
Thinking about the issue, this is so "off" that it can not possibly be on purpose - can this be an issue of the 3.1.8 firmware?
Call for help: Can one of you guys try who does not yet have the 3.1.8 installed?
Steps to reproduce:
- Connect QC 35 to device
- In "music mode" (A2DP) verify how typing sounds through noise reduction
- Switch to HSP/HSP
- In Windows: activate and use "Handsfree Telephony" service under headset in device manager (Devices and Printers)
- In Linux: Change profile in bluetooth device settings (easy)
- In Android: Call any number that will not pick up the phone and just let the phone ring (initiate a call)
- In "call mode" (HSP/HSF) verify how loud typing sounds and how you can suddenly hear what your mic picks up
