Most are pretty good - look at them on display to check picture quality. As far as a sound system, I like Bose. I use the small Bose Wave for my TV sound - especially when a lot of music in a show. It sounds better than the TV’s sound. I’ve seen ads for the Bose under the set systems and would imagine that they sound good and might also have a jack for phones. Probaly cheaper than a lot of other specialty sound systems.
Do you have the model of the bose system you use? Or a link to it?
