This 5.1.2-channel Dolby Atmos soundbar packs a surprising amount of connectivity into a mid-range package. Two HDMI ports handle video passthrough and eARC, so you can route a single cable to your TV and get lossless Dolby TrueHD and DTS-HD Master Audio back. A dedicated 3.5mm voice assistant input lets you wire an Echo or other smart speaker directly into the system. Optical and USB-A round out the inputs for legacy devices and local file playback.
