Quiet comfort 35 ii not connecting

I’ve been using quiet comfort 35 II for two years now. It was working perfectly fine until this evening. I was connected to my iPhone XI Pro and MacBook Air. Suddenly I started hearing background noise in my headphones even though noise cancellation was turned on. I was listening on my MacBook and when I stopped that and wanted to listen to something on my iPhone, it did not play anything even though it said connected to my iPhone. I tried turning off and turning on both my iPhone and my headphones but didn’t work even after that. I tried resetting the headphones but after I turn off, when I connect to power and then when I try turning back on, I just hear “Battery 80%” and then one small beep and then the background noise. It did not say “Connected to my iPhone or MacBook”. Now it’s not connecting to any device. And anytime I turn it on, it just says the battery percentage and beeps one time and then there’s just continuous background noise but it’s not connecting to any device or working. I even tried connecting via cable wire to check if this was only a Bluetooth issue, but even the wire didn’t work.

Hello Satish7, 


Thank you for posting and reaching out to the Community today for support. We would love to assist you further with this connection issue you are experiencing. 


I understand that you have already attempted a reset, however I want to ensure that you are performing this correctly. To perform the reset please follow these steps below: 

  • Power off your product
  • Wait 30 seconds
  • Connect your product to a wall outlet using a USB charger
  • Wait five seconds
  • Disconnect the USB cable from the headset
  • Wait one minute
  • Power on your product.

Let's also ensure that the headset is up to date by connecting the headset to a PC/Mac via the USB charging cable. Once connected please visit our online updater and follow the on-screen instructions.


We look forward to hearing back from you with the result of these steps.
