You can also check our thorough list of the best soundbars you can get today, regardless of connection type.
Connectivity (HDMI & Other Connections)
HDMI is the best option for wired connection  as it is able to handle high-frequency loads and pass-throughs. Any 5.1 or higher audio settings or advanced Dolby or DTS technologies also require HDMI connection.
Digital cables are the next best thing if your soundbar doesn’t support HDMI. There are two types: digital optical or digital coaxial. Both these cables are capable of transmitting audio up to 5.1.
You should decide on the setup you want for your living room. If you are limited on space, the Sonos Beam is a great option that can be wall-mounted to keep out of your way.
Other design considerations include whether or not your soundbar has a built-in display or indicator lights to show your settings clearly, or a control panel built-in for an extra option for control.
For true surround sound quality, you need 5 or more channels on a soundbar, but we’ll cover more of that later.
Another defining factor for superior sound quality is the advanced audio technologies incorporated in the soundbar. Dolby and DTS are industry-leading standards that can bring the theater into your living room.
There are also brand-specific technologies such as Sony S-Force, LG Merdian, and Clear Voice and Voice Adjust technologies that will help enhance dialogue.
Factors such as the embedded audio technology, number of channels, components, and extra features determine the price, so you should decide which ones will matter to your experience.
An external subwoofer with a soundbar will further enhance the deep bass notes more than built-in ones. However, a soundbar can also have a subwoofer built right into the cabinet. The embedded sub is a great option for those who still want improved bass tones but lack the space.
