Audio cuts out on far end during a call

When the headphone's battery level is at 10% or less, a voice prompt notifies you that your battery is low and to charge the headphones. If you are on a call while this happens, your voice will cut out. Firmware update 2.0.4 resolved this issue. Make sure you have version 2.0.4 or later.

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.

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.

When in multipoint, a secondary Bluetooth device could possibly receive a text/email notification and try to broadcast audio to your product. This could interrupt the primary Bluetooth connection/audio stream which effects Bluetooth bandwidth, causing intermittent audio or sporadic Bluetooth connections.

To eliminate any interruptions, we recommend turning off Bluetooth on your secondary device which is connected to your Bose product.
