Rated 3 out of 5 by from loved it until I didn't bought this unit six months ago -- sound stopped working last week -- could get it to work if I disconnected power and/or speakers and reconnect -- otherwise it would simply go to "S-protect" -- (speaker protection). kept it on for several days afraid to turn it off -- then did -- and viola -- no sound no jiggling could get it back - obvious short somewhere -- after a go around with LG on the phone -- now waiting for a label and a box to send it back to LG for "repair" -- big hassle - no idea how long this will take - so I had to buy another unit -- different brand -- smaller -- so I could have music in my studio. old fashion me -- thinking something would work longer than six months. I really liked this unit ... until ...

Rated 3 out of 5 by from EQ/wiring/tv sync I bought this as it was awesome in the store. Didn't realize wiring was direct into the speakers and sub.Would be nice to have length.EQ and sound effect are pretty much the same,but o.k.Cranks pretty loud! Would be better if you could sync to any tv, only LG. Overall it's nice for the price.

Rated 2 out of 5 by from Delivery Was Faster Then I Expected! I was impressed with the quick delivery but didn't like that the system was not able to hook up to any type of headphones or earbugs. Good style and sound though.

I have a regular headphone. I plugged it in but the sound does not come through. How or what should I do to fix this

Asked by: Fisher 60
The LG 700W 2.1ch Mini Shelf System with Built-in Subwoofer and Bluetooth®, Model # CM4550 does not have a headphone jack on it. It sounds like you plugged your headphones into the Portable In on the front of the unit which is designed for plugging in portable devices to play through the CM4550. It will not work for headphones...^IFV

I have an older model flat screen LG tv, just received this system. Aux cords aren't working. Can't find anything in audio settings on tv. How would I connect this? USB? That optical port thing?

Asked by: LotusNyx
Look on the back of your TV & see if you have an optical digital output connection. If so, you will need a converter box. My LG TV is older but apparently one of the first models with the digital output. Once you get the converter, it'll work great and you won't disappointed. (These converters will also allow you to use headphones with this system, despite it not having a headphone jack!)
