●The SW03 pro Bluetooth wireless audio transmitter supports two audio transmission modes: "USB Mode" and "Optical Mode." It adds Bluetooth functionality to devices without Bluetooth, such as TVs, computers, laptops, and game consoles (e.g., PS3/4 series/XBOX series), allowing them to connect to Bluetooth speakers or headphones. It supports simultaneous connection of two Bluetooth speakers or headphones. ●The SW03 uses the latest Bluetooth chip technology, so it won't show up as a Bluetooth device on your phone, computer, or TV. Simply bring your Bluetooth device close to the transmitter to automatically connect. (Note: This product is not a "USB to optical fiber" converter.) ●Utilizing the ATS Bluetooth 5.4 chip and low-latency lossless decoding technology, it ensures flawless sound quality and high-quality audio, allowing you to experience CD-quality HiFi music. ●Supporting dual-stream and multi-point connection, it can connect to two Bluetooth headphones or speakers simultaneously. (For best results, use the same Bluetooth headphones or speakers or the same audio codec.) Color: Black Material: ABS Package Contents: 1 * Audio Transmitter
