I just purchased this as a packaged deal with my Samsung smart tv. I really thought that it was going to improve the sound(and it may be my ears) but the quality of the sound doesn’t seem as crisp or clear. I I have to turn it up to 70-80 to get a clear sound. I have it hooked up as Bluetooth . Maybe if I reconnect as optical it would sound better. I’ll wait till my husband hooks his up and see. But it is very well made. Maybe I’ll switch from Bluetooth to optical hookup and see if the sound improves
