Microphone picks up sound intermittently | QuietControl™ 30 wireless headphones
Make sure nothing is covering the outside screens on the earbuds.
Both earbuds should be free of obstructions. There are several microphones located inside the earbuds, not the inline remote.
- Two mics in the left ear bud for noise cancellation
- Four mics in the right ear bud; Two for noise cancellation and two for phone calls
Determine if an iPhone or other Apple device is paired to the headset.
When the Bluetooth® antenna of an Apple device is obstructed the user of the headset may experience poor Bluetooth performance. In the case of the iPhone, the Bluetooth antenna is located along the top side of the device. It is recommended that the phone be stored on the right side of the body (belt clip, pocket, hand) and to assure the top of the phone is exposed while on an active call using the headset.
Bring device to the front of the body to eliminate body-block interference
The Bluetooth® antenna is located on the right side of the neckband underneath the Bose logo. Having the Bluetooth device in a back pocket, bag or a backpack could cause loss of connection.

Please Note: The human body can act as a source of interference for Bluetooth and radio signals. Bluetooth sources positioned immediately next to a person (in a pocket, for example) may result in intermittent or loss of connection. For best results have the Bluetooth source closer to the product (i.e. in a front pocket) to reduce the potential for “body-block” interference.

If using your product outdoors, check for differences when used indoors.
Since there are fewer boundaries and reflective surfaces outdoors, Bluetooth® signal might not reach as far. Check if the product functions better indoors to determine if the environment is the issue.
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
Keep your product within 33 feet (10 meters) of your personal device.
Distance and obstacles like walls, doors, or other electronics can weaken the Bluetooth signal. If you're having trouble, try moving your personal device and product closer together or relocating other devices that may cause interference.
Try disconnecting other nearby wireless devices that might interfere with Bluetooth® signal.
Some wireless devices can cause interference with a Bluetooth signal.
Common examples include:-
Common examples include:-
- 2.4 GHz router
- cordless phone
- wireless speaker adapters
- home security motion sensors
- fluorescent lights
- microwaves
- wireless mice and keyboards
If you're experiencing intermittent audio during phone calls, check your cellular reception.
This issue may be caused by a weak connection to the cellular network. Enabling Wi-Fi calling in your phone's settings while connected to your home network can help, or you can try the call again once the reception improves.
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.
Try connecting a different Bluetooth device.
If your Bose product can connect to another device, Bluetooth functionality is working. In cases like this, the issue could be with the first device or its settings.
