Summary: I received the HW-J450 model as a Christmas gift. The sound quality was just OK. So, I returned it for a refund, and upgraded to this HW-H750 model, supposedly top-of-the-line. It's defintely not.
Summary: this system is loud!! I had the subwoofer cranked and was blaring Star Wars and my wife said she could hear it down the road! The only downside is sometimes the hdmi gets a little finicky and won't pick up a signal so you have to screw with it a little.
Summary: I went from a full 5.1 Home Theater System until last Thursday, lightning took everything out including my 3 AudioQuest very expensive HDMI interconnects... So i just set up a new Samsung 4K UHD 6500 series HDTV with this Samsung HW-H750 Wireless Audio Soundbar, last night i viewed Ex Machina SCiFi...
Summary: Perfect with Samsung TV. It's like and extension of the TV. Almost nothing to do for the installation. Automatically recognize by the TV (Acc Device has to be set to ON). The Voice setting os perfect for a clear quality.
