Summary: I purchased a used-like new model from Amazon. Everything was great at first I used mostly my HTPC into the soundbar and then soundbar to the TV via HDMI. However, the day I decided to add my XBOX to the soundbar via HDMI, I started to experience the popping sound. They are extremely annoying and if you let it go long enough eventually all the sound will become muffled.
Summary: This unit produces good sound, but is actually a piece of junk. It pops and bangs randomly and very loudly. The on-screen display contains only the volume bar, not the other 2 features it is supposed to include. I have found that trying to programme the TV remote to handle the volume up, volume down and mute functions is impossible. The first unit I had had to be replaced because of the failure of the remote control function.
Excerpt: Hooked this up this afternoon with a HDMI cable that I had. Sounds great until it starts popping every 10 minutes. Looked online and found some comments about using the analog cables included, so I did that, moved the subwoofer to a different outlet and now it only pops every 20 minutes. Anyone else have a fix, or is this getting shipped back?
Excerpt: I bought it as a christmas present for my son. He hooked it up, sounded great, but had an intermittent "pop". The sync of video and audio was not reliable. He returned it. Hooked up the replacement unit, same problem. Sent it back for a refund. We are both very disappointed. I still have my Decade 36 speakers from the 70's, very low tech, but still sound great.

Summary: I was depressed from the reply. This is the official reply on open security in Bluetooth which I got twice. If you live in apartment or a place where you identify your neighbor, do NOT buy it. This is serious trouble than you expected. ============= This is our official answer. In order to provide it to you i have send your comments internal to our higher technical department. Again i must inform you that Harman is aware of this fact and it is working as intended.
