Summary: The SB400 was packaged well and was easy to set up. The bar easily connected to the subwoofer, and then via bluetooth to all mobile devices in the house. Hanging the bar didn't seem very stable though, as it has a very loose connection to the cleat you attach to the wall first. Also, I mounted my bar to the wall below the TV, so I had multiple wires going between the two, which the SB400 just doesn't accommodate well.
Summary: I have already had to send this thing back once (advised to do so by JBL); although it was within the amazon return period. I will have to actually return the one i currently have to JBL. The system intermittently chirps/pops (nowhere near as bad or as loud as the first one I had). JBL opened a ticket for me to request future support against, and it looks like I'm going to need it. I am disappointed in this purchase and in the product that JBL provided in this case.
Summary: I thought it would be nice to have HDMI switching, but this unit makes INCREDIBLY LOUD popping sounds at random times. It does sound good, but the noises and popping was unbearable. I got a Harman Kardon SB15 that sounds just as good for way less money. Skip the HDMI sound bars.
Summary: The SB400 would be awesome if it wasn't for the snaps and pops that happen when using the HDMI inputs. The Bluetooth works great, the optical input works great, the subwoofer is great, the speakers are better than my Samsung TV's but I think that is mostly because they are pointing at the listener vs. out the back like the TV. You don't notice how bad all the soundbar speakers are until you compare them to something like my old Toshiba 57" rear projection tv.
Summary: JBL dropped the ball on what could have been a fantastic sound bar. Every aspect of this bar is great except for 2 details. THE GOOD:The sound quality, the connectivity, ease of use and styling are all 5 stars. THE BAD: If you are mounting system consists of tabs on the wall brackets and slots on the bar which is fine for wall mounting.
