What people are saying
Rated 1 out of 5 by from Bluetooth Stop Working w/Mobile Devices Had my NB3530A system for some time now (approx 5 yrs, maybe longer), I guess I'm fortunate after reading some of the other reviews as my system still works great aside from the bluetooth feature for mobile devices. Stop working with my smartphone & Tablet.

Rated 1 out of 5 by from Bluetooth connectivity. I’ve had this unit a couple of years with no problems and I’ve been very pleased with it, however all of a sudden the Bluetooth connectivity isn’t working anymore, every device I’ve been using on it will not connect to it at all, it seems from the posts I’ve been reading about this unit all seem to have a Bluetooth issue. Will I buy another LG sound bar? I don’t think so. I’ve a couple of LG TVs and had these some years with no issues however I’ll give the sound bars a miss in future.

Rated 1 out of 5 by from The Bluetooth between the sound bar and sufwoofer. The subwoofer loses connection everyday for the past year and I’m tired of trying to constantly on a daily basis. Sometimes more than once a day. The mute and repair button sync never works. I can’t get the repair message to come up. It’s very frustrating. I had this for a while. The only thing I can do is it reset on back of subwoofer and unplug and replay it in. Most times that does not work either. It’s the luck of the draw for it to work. But I can’t return it to the store to get my money back and can’t afford a hardwired system. No wonder this model is discontinued

What portable bluetooth speakers can I connect my sound bar. I have sound bar NB3530A.

Asked by: Bernie1953
Hi Bernie1953. The LG Sound Bar Audio System with Bluetooth Connectivity, Model # NB3530A will receive Bluetooth audio signals from other devices that it is paired to, but it does not transmit Bluetooth signals so you cannot pair it to other speakers that are also just receivers...^IFV

My Sound bar “bt ready” will not appear on the screen. Must I reset my sound bar NB3530a or is it broken?

Asked by: NOLA101
I was told that if BT Ready doesn't show, it means that it has been paired to a previous bluetooth device and it cannot be paired with another phone, and the old pairing cannot be cleared. If there is a way to clear the settings, I'd be interested to know.
