No, Bluetooth headphones do not use a sound card. Bluetooth headphones communicate wirelessly with your device (smartphone, laptop, etc.) through a Bluetooth connection. This eliminates the need for a physical sound card, which is typically used to process audio data in wired devices. Instead, Bluetooth headphones have built-in DACs (Digital-to-Analog Converters) and AMPs (Amplifiers) to decode and amplify the audio signal directly. This makes them convenient and versatile for various devices without requiring additional hardware.
