Microphone picks up sound quietly or poorly

Wind noise may enter the microphone capsule and render other audio unintelligible. Moving away from this area may allow for clear audio reproduction

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.

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

Some wireless devices can cause interference with a Bluetooth signal. 
Common examples include:-

• 2.4 GHz router
• cordless phone
• wireless speaker adapters
• home security motion sensors
• fluorescent lights
• microwaves
• wireless mice and keyboards

If there are such devices, disconnect one at a time and check if the issue improves. If so, consider relocating your product or the 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.)

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.

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.

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.
