QC35 Keeps Clearing Bluetooth List

[Romsey]

Hello!

My headset keeps clearing its bluetooth list after a few moments. At first I thought I had paired too many devices so went through all of them and removed any connections. I have updated it to the latest firmware

(Version 2.5.5) but I had to do so manual via micro-usb as the headset would cut off while updating via the iPhone app. From my understanding, you would have to hold the power button to the right for 30 seconds for the headset to clear your bluetooth list but I have made sure that the switch is at the neutral position (and feels normal in the sense that I would have to apply pressure to the right in order to switch to pairing/clearing mode). Has my faithful QC35 become obsolete? 

Please spare me from the sounds of construction across the street,

Hello @Romsey!

I'm sorry to hear of the issues that you've had with our headphones, and would like to welcome you to the Community.

Whilst I can't do anything about the construction work in your area, i'd be glad to help get your headphones up and running!

First of all, I would ask that you try out the following and let me know what happens:

1) If you are only using 1 product at a time, does using a different product have any kind of impact on your product cutting out, or is this universal across all products?

2) As you have already removed many of the connections from the headphones, can I also ask that if you choose to forget the device from the Bluetooth menu and pair again, does this stay connected, or disconnect again after the rough 30 second period?

3) If you connect this headset via the AUX cable, does this continue to play correctly, or does this skip at the same interval as when paired through Bluetooth?

As an extra question, can I ask if these are the QC35 I or QC35 II?

Please get back to me when you can to let me know how these go!

Liam,

I am also having the same problem with my QC 35 I’s.

It just randomly will drop my Bluetooth devices, especially when I’m to pair.

Once cleared, my device has a hard time re-pairing to the same machine, and i have to manually every time forget the device then retry pairing.

1.  If i use just 1 product, sill does the same thing.

2.after forgetting, still clears the list every once in a while.  I am not sure exactly how long it takes.

3.  The aux cable works fine, not sure what you mean by skipping.

Hello Eddieskim,

Thanks for posting and welcome to the community! I am sorry to hear that you are experiencing difficulty with your QuietComfot35 headphones, I would be more than happy to assist you further with this today. Thank you for providing the information it is very helpful, have you tried a product reset? Have you tried rebooting the device you are trying to connect with the headphones? Have you tried connecting a new device? 

To reset your product:

1. Power off your product, then wait 30 seconds
2. Connect your product to a wall outlet using a USB charger, then wait five seconds
3. Disconnect the USB cable from the headset, then wait one minute
4. Power on your product.

It might also be helpful to reboot your network router, can I also confirm that when you are clearing the paired list it is via the steps below:

1. Power on your headset
2. Slide the Power switch to the Bluetooth icon and hold it for 10 seconds until you hear Bluetooth device list cleared.

I hope this helps, I look forward to hearing from you!

Kindest regards,

Zoe C

same problem, for no reason clears the list just like the previous guys describe also fails to pair unless I just connect it like any old bluetooth device (which is why I suspect it is a software problem)

My QC35s also have the same problems as set out above.   I have tried the troubleshooting suggested above but it doesn't solve the problem.  When I turn my headphones on, it automatically clears the bluetooth list again.

Hey,

I am also having the same issue and have tried the above troubleshooting to no avail.

Is there anything else I can try? 

Thanks,

Steph

Hi Romsey

I have the same issue, which persists after updating the firmware and doing a factory reset.  It is as if the 'Power/Bluetooth' switch is being slid over to Bluetooth.  In other words, for a few minutes the headphones work fine, then I hear voice prompts to the effect of "Pairing to another device" and then "Bluetooth Device List Cleared".  Of course, the real frustration is that once the bluetooth device list is cleared, I am disconnected from my device and then need to complete the arduous process of reconnecting.  This involves forgetting the earlier connected device, etc.

It seems as if the headphones have become faulty whereby the 'Power/Bluetooth' switch is no longer able to remain in the neutral position?  Does this comport with others' experience?

Thanks, Paul
