A:Answer Hello, this item is a Bluetooth transmitter that allows you to use Bluetooth headphones with your TV. Generally, you do not need a soundbar in this setup. If you have a soundbar already connected to your TV an occupying your optical port (for example), there are ways to make that setup work using an optical splitter. Our support team is able to answer questions pertaining to your specific setup, but would need to better understand how your TV is set up now and what you are looking to accomplish. Please give us a call at 626-965-1008, M-F 9am-5pm PST and we'll be happy to understand your specific setup and how a soundbar factors in, and make appropriate recommendations. Thank you.
