Going from standard TV sound to a proper soundbar is the audio equivalent of going from VHS to 4K. If you haven't stepped up your game yet, Sonos currently has a great deal on refurbished units of their flagship Playbar speaker which are normally $699 but can be purchased for $549 right here.
A seamless and easy way to upgrade your TV’s sound, it can also be integrated into an existing Sonos system for cohesive music throughout your home or link with specially placed Sonos speakers for wireless surround sound. The only downside? It doesn't support Alexa like Sonos’ newer speakers but given the many privacy issues that continue to pop up with voice assistants, we don't really see it as an issue.
