Very high quality sound - it is a good supplement to the smart tv it is connected to for sound

I Regret Buying This Sound Bar

This device has extremely limited connection options and worse yet is not very loud. Then if you want to use the App it REQUIRES you to create an LG account which means LG simply wants to ID your device so it can snoop on you and maximize profits selling your information to their so-called 3rd party affiliates (whoever they may be). You are even forced to agree to let them sell YOUR information. LG is just another intrusive corporate hack snooping people to line their pockets.
