BTD 700 connection to iPhone

Setting up USB audio on iPhone

• Make sure the headphones are not actively connected via Bluetooth. iOS defaults to Bluetooth when available – if in doubt, turn off Bluetooth while setting up the dongle.
• Connect the BTD 700 while the phone is unlocked. iPhones require permission to use USB accessories and may not recognise the dongle if locked.
• When the iPhone asks what type of device is connected, select "Headphones."
• If the connection type prompt does not appear, go to Settings > Sounds & Haptics > Headphone Safety > USB Audio Accessories to ensure proper recognition.

If audio stops working when the iPhone locks

1. Go to Settings > Face ID & Passcode and enter your passcode.
2. Scroll down to Allow Access When Locked.
3. Turn on the toggle for Accessories.
