- On your device (smartphone, laptop, tablet), go to Bluetooth settings and enable Bluetooth.
- Search for available devices and select "Altec Lansing Comfort Pro" from the list.
- Once connected, the LED indicator will stop flashing and remain solid blue.

Active Noise Cancellation (ANC) & Environmental Noise Cancellation (ENC)
The Comfort Pro headphones feature powerful ANC to block out external noise and ENC for clear calls. Press the dedicated ANC button to toggle between ANC On, Ambient Mode (allowing some environmental sounds for awareness), and ANC Off. ENC is automatically active during calls to ensure your voice is clear.
Spatial Audio
Experience immersive sound with Spatial Audio. This feature creates a 3D soundstage, making audio feel more lifelike. Spatial Audio is automatically enabled when supported by your device and content.
Low Latency Mode
For gaming or video playback where audio-visual synchronization is critical, activate Low Latency Mode by triple-pressing the MFB. This reduces audio delay for a more synchronized experience.
Voice Assistant
Access your device's voice assistant (Siri or Google Voice) by double-pressing the MFB. You can then issue commands through the headphone's microphone.
Call Management

- Reject Call: Press and hold the Power button for 2 seconds.
Maintenance
Cleaning
To maintain the performance and appearance of your headphones:
- Wipe the earcups and headband with a soft, dry, lint-free cloth.
- For stubborn dirt, lightly dampen the cloth with water. Avoid using harsh chemicals, solvents, or abrasive cleaners.
- Do not allow moisture to enter any openings.
Storage
When not in use, store your headphones in the provided carrying case to protect them from dust, scratches, and impacts. The foldable design allows for compact storage.

- Cannot pair with device:
- Ensure the headphones are in pairing mode (LED flashing rapidly).
- Turn off and on Bluetooth on your device.
- Delete "Altec Lansing Comfort Pro" from your device's Bluetooth list and attempt to pair again.
