Hi there! While a soundbar isn't necessary, the addition of one is recommended for a heightened audio experience. Should you choose to add a Samsung Soundbar to your TV, the HW-Q800H Soundbar would be a great addition to the QN80H TV. With 5.1.2ch audio, built-in Wireless Dolby Atmos, and SpaceFit Sound Pro, you’ll get room-filling audio that’s automatically optimized and calibrated for your space - all without the hassle of attached cables. And with Q-Symphony, our Q-Series Soundbar will synchronize with the speakers of the TV for an immersive 3D sound experience.
