BOSE QuietComfort 45 Noise Cancelling Headphones Instructions

BOSE QuietComfort 45 Noise Cancelling Headphones

Product Information

The product is equipped with a microphone that may pick up sound quietly or poorly. This can result in difficulties for others to understand you during phone calls. The following troubleshooting steps can help resolve this issue:

1. Move to a less windy environment:
   Wind noise can interfere with the microphone, making the audio unintelligible. Moving to an area with less wind can improve the audio quality.

2. Place another phone call:
   Make a call to another number to determine if the issue occurs consistently or only with certain people. Poor reception with the phone service or device being called may be the cause.

3. Check the cellular reception:
   Poor audio quality during calls can be caused by a weak connection to the cell service. Try making the call again when the reception improves.

4. Check for wireless interference:
   Some wireless devices can interfere with the Bluetooth signal of the product. Disconnect any nearby wireless devices (e.g., 2.4 GHz router, cordless phone, wireless speaker adapters, home security motion sensors, fluorescent lights, microwaves, etc.) one at a time to identify if they are causing the issue. Consider relocating either the product or the interfering device if the improvement is observed.

5. Remove and reseat the audio cable:
   If using a connected device, disconnect and then reconnect the cable that connects your headset. Ensure it is fully connected and secure. If crackling or intermittent sound is heard when rotating the plug in the jack, there may be debris or a contact issue inside the jack.

6. Reboot the connected device:
   Power off the connected device and then power it back on. This can help resolve minor issues that may affect audio quality.

7. Check the condition of the headphone cable:
   If the plug or any part of the cable is damaged, it can affect the audio quality. Consider replacing the cable if necessary.

8. Reset your product:
   If experiencing minor issues, resetting the product can help resolve them. Refer to the user manual for instructions on resetting your specific product.

9. Bluetooth range:
   The Bluetooth range of the product is approximately 33 feet (10 meters). Obstacles such as walls, doors, pockets, and nearby Bluetooth devices can reduce this range. Try moving the device and product closer together to improve connectivity.

10. 10. Check for wireless interference (Bluetooth):
    Similar to the previous step, disconnect any nearby wireless devices that may be causing interference with the Bluetooth signal. Test the product after disconnecting each device to identify the source of interference.

Troubleshooting

The microphone picks up sound quietly or poorly:
If the microphone on your product picks up your voice quietly or with added noise that makes it difficult for others to understand you during phone calls with your product, try the following:

Move to a less windy environment
Wind noise may enter the microphone capsule and render other audio unintelligible. Moving away from this area may allow for clear audio reproduction

Place another phone call.
Try placing another call—preferably to another number—to determine if the issue occurs all the time or only with certain people, which could result from poor reception with the phone service or device you call.

Check the cellular reception of your phone.
A weak connection to the cell service could cause poor audio quality while on a call. Try the call again when the reception improves.

Try disconnecting other nearby wireless devices that might interfere with the Bluetooth® signal.
Some wireless devices can cause interference with a Bluetooth signal. If there are other wireless devices nearby (i.e., 2.4 GHz router or cordless phone, wireless speaker adapters, home security motion sensors, fluorescent lights, microwaves, etc.), disconnect one at a time and check if the issue improves. If so, consider relocating your product or the device.

Remove and reseat the audio cable in the connected device.
On the connected device, disconnect the cable that connects your headset. Then, reconnect it to be sure it is fully connected and secure. (Tip: While connected, if you rotate the plug in the jack and hear crackling or intermittent sound, there might be debris or an issue with a contact inside the jack.)

Reboot the connected device.
Electronics might need to be reset from time to time—much like rebooting a computer. Power off the device, then power it back on and try again.

Try connecting a different Bluetooth® device.

Clear your Bose product memory of previously-connected Bluetooth® devices.
Your Bose product remembers the last several devices it connected to so it can quickly reconnect to them. In case there is an issue with the device’s memory, clear it and then try to reconnect the device. For more info, see Clearing the product memory of paired Bluetooth® devices and Connecting a Bluetooth® device.

Remove your product from the memory of the Bluetooth® device, then try again.
In the Bluetooth settings of the Bluetooth device, find the list of previously connected products. Remove your product from the list, then reconnect it to the device. For more info, see Connecting a Bluetooth® device.
