TIP: USE WIRED HEADPHONES FOR THE BEST EXPERIENCE
While the app supports Bluetooth devices, using a high-quality wired headset provides the most reliable audio with the least amount of lag. This ensures that the sound you hear matches up perfectly with the lip movements of the person talking to you. It also helps preserve your phone’s battery life during long conversations or while watching TV.
