It is critical to remember the Bluetooth feature when using the Bose Quiet Comfort 35 headphones to take calls. You cannot use it while the product is charging, which disables the microphone.

If you need to charge the battery in your QC35 or QC35 II, you must first turn off the product. Connect a USB cable from your headphones to your charger next.

When the battery is charging, the battery light blinks amber. You'll be able to use it again once it turns a solid green color. The battery usually charges in about three hours, though the actual time depends on the charger you're using and the remaining power levels.

You won't have to worry about overcharging your battery if you leave the Bose Quiet Comfort 35 headphones plugged in overnight. Even if the product is still connected, the power levels must fall below a certain threshold before triggering another charging cycle.

■ How to Check on the Remaining Battery Life with Your QC35s

Although the Bose QuietComfort 35 headphones have a battery life of up to 20 hours on a full charge, this is not guaranteed. Several factors influence the total amount of time you can use the product, ranging from microphone use to general audio streaming.

If you're unsure how much time you have left to use your QC35s or QC35 II headphones, you can check the charge levels by following the steps below.

  1. When you turn on the Bose QuietComfort 35 headphones, a voice prompt will announce your battery charge level. The LED indicator also illuminates for about ten seconds to show you its current status.
  1. If the headphones are already turned on, you can activate the LED indicators by pressing any button on the product. To conserve battery power, they will turn off after ten seconds.
  1. A solid green light indicates that you have at least one hour of battery life left when the QC35 and QC35 II headphones are not charging.
  1. When the headphones aren't charging, a solid amber light indicates that you have less than 60 minutes of battery life left. This indicator indicates that you should locate the charger.
  1. When you see a blinking red light on the product, it means the battery needs to be charged.
  1. When you plug the Bose QuietComfort 35 headphones into a charger via the USB port, an amber light blinks to indicate that the product is charging. When you've finished, it will turn a solid green color.

Depending on the conditions, you'll need to relocate it somewhere cooler or warmer.

If you bought the QC35 headphones to take phone calls, there may be times when you try to speak with someone and the microphone does not appear to work. The most common cause of this problem is a lost cellular or Bluetooth signal. If your phone isn't connecting to someone else, the microphone will appear to be broken.

You can see if the headphones respond to other vocal commands to see if this is affecting your user experience.

If your Bluetooth signal is disrupted or there are multiple barriers between the headphones and the phone, the microphone may not function. When listening to music or speaking with someone, you'd also notice audio interruptions.

If both issues have been resolved but the QC35 phone mic is still not working, you may need to update the firmware, software, or both for your device.

This step frequently improves the product features and overall stability of the headphones, ensuring that your investment continues to meet your needs.

The QC35s or QC35 II headphones can be updated using the Bose Connect app or by connecting the product to your computer.

Here are the steps to follow so that you can have a successful experience.

  2. You’ll get asked to view the terms and conditions of using the site. You cannot start the updating process until clicking on the “Accept and Continue” button.
  3. Click on the “Download” button to save the file to your computer or laptop.
  4. Once the file is finished transferring, open it so that you can install the updater. Although the pages should automatically advance, there’s a link that says “Click Here” if you need to manually activate it for some reason.

■ How to Update Your Bose Headphones through the Companion App

If you use the Bose companion app with your QC35 or QC35 II headphones, you may find that the updating process is a little easier.

Instead of guessing whether an update is available or not, the app displays an icon indicating that something new for your headphones is available. It appears as a downward arrow on top of the image of your product.

When a software or firmware update is available, the downward arrow image will appear in your product settings menu. If you receive this notification, you can update your Bose QuietComfort 35 headphones by following the steps below.

  1. Tap on the update icon that displays in the Bose companion app. Once you take this step, you’ll see a circular progress bar that indicates the download process’s current status.
  2. After the download is complete, you will want to tap on the “Update” button that appears on your screen. It will have the downward arrow appear next to it.
  3. As the Bose QuietComfort 35 headphones start updating, you’ll need to wait a couple of minutes for everything to install. You’ll see a circular loading bar appear around your product, but it is a visual indicator to stay rather than a progress symbol.
  4. When the checkmark appears on your mobile device, you’ll know that the update is complete. You can start using your headphones once again.

If you see an error screen while performing these steps in the Bose companion app, there may be a problem with the software or firmware that needs to be addressed.

In those circumstances, the first step would be to try a computer update. If that fails, you'll need to contact Bose to arrange for the headphones to be repaired.


When using the QC35 headphones to make phone calls, I discovered numerous advantages and disadvantages. Although the microphone is clear, my experience has not been as positive as the product's marketing descriptions suggest.

When using the QC35, noise-cancelling benefits come through the mic, but they aren't as strong as when listening to audio. Is it better than what someone would hear if you spoke directly on the phone? Probably.

As a result, when using the Bose QuietComfort 35 headphones for phone calls, it is critical to have realistic expectations. They won't be perfect, but they'll do well in most situations.

You'll just want to avoid high-noise areas, just like you would for any other call.
