Summary: As with many products made by Samsung, it's either hit or miss. This is a big miss. We kept it because we are too lazy to return it and it is better then the WORST build-in speaker our Samsung TV has... So, long story short - sound quality is comparable to by grandmothers radio from 1940's and "settings" are just there to make it good "options" - they are worthless. Don't buy it. Spend extra $100 or so and get something better.
Summary: I bought a Toshiba 40" LCD HDTV several years ago when it was on sale with a very good price (at that time). Then I realize the sound quality of it is really bad as a result of cutting cost. I found this sound bar and the Vizio one on sale at around the same price 2 years ago. After comparing the style and reviews, I decided to keep this Samsung one. I am using the optical output from the TV to connect to the sound bar. It has 2 optical digital and 1 analog input.
Summary: Bought this Samsung soundbar in early Dec. 2012 as refurb. Looks brand new & works well as TV speaker but when I play a music CD at medium volume the speakers crackle. Not so with high TV volume. Just not adequate for music.
