Microphone picks up sound intermittently

If the microphone on your product picks up your voice inconsistently or people say you are cutting in and out when making phone calls with your product, try the following:

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

Be sure your product is within 33 feet (10 meters) of the Bluetooth® device.

Bluetooth range is about 33' (10 m). This range can be reduced by obstacles (i.e. walls, doors, pockets, nearby Bluetooth devices, etc.). Try moving the device and product closer together.

Try disconnecting other nearby wireless devices that might interfere with 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.

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.

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.

Reset your product.

Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more info, see Resetting your product.

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.

Your product may need service.

If the steps provided do not resolve your issue, your product may need service. Follow the link below for more information on how to service your product. Depending on your product and region, you will be provided a contact number or the ability to setup service online.
