Does connecting the QC 35 II to a PC via this cable https://www.bose.com/en_us/products/headphones/headphone_accessories/quietcomfort-25-headphones-inli..., + audio/mic splitter let you use the QC 35 II headphone mic without bluetooth and sidetone?
Thanks for your question.
The QuietComfort 25 inline connection cable is compatible with your QuietComfort 35 II headphones. Once inserting the cable this will disable all Bluetooth functionality of the headset, but will allow you to use the microphone on the inserted cable. Regrettably I cannot guarantee that this will remove any sidetone.

@Tegan_M , thanks for your response. Just curious, why are you saying that you cannot guarantee that the side tone would go away? Shouldn't the sidetone should go away since side-tone is only activated when a mic is used over bluetooth (plugging in the cable automatically disables bluetooth, as you said)? It would be helpful to have the option to switch off the sidetone as it creates white noise in the speakers that is tiring after an entire day on the phone.
