What People Are Saying

Rated 5 out of 5 by from Little thing rocks!! This was given to me as a present for my birthday (51) by my wife. Very easy to set up and program which was a major plus. Too many devices now have 20 plus pages of setup. It supports my phone and usb plus the cd is great. Im old school so a cassette deck would have been great but my kids are educating me in all the latest things. I listen to country, jazz,old school rock, heavy metal and others so i like diversity. This little unit shakes the house and upsets the neighbors sometimes but the clarity from low to the absolute loudest it will go doesnt vary. The range of preset settings from basic to rock to arena gives you plenty of options to choose from. Possibly a setting for a customized setting or manual would allow the listener to fine tune what they are comfortable with. With that said i will keep rocking this little beauty til it explodes. Great unit from a reliable company. Thanks.

Rated 5 out of 5 by from Wonderful stereo shelf system This stereo has it all. From Bluetooth to AUX outlets. It sounds awesome, however the base could deeper. Practically has no competition in its price range. Looks good too.

Rated 3 out of 5 by from Neighbors sigh I love this stereo however I don't like my neighbors being able to interrupt my shows and music with their music. A password needs to be required on these systems to avoid that.

Rated 2 out of 5 by from Bluetooth I’ve received this stereo as a Birthday gift in 2016, but until now someone has been accessing my stereo through their Bluetooth which is scary and unbelievable! Please make these systems with an option for you to turn off this option and make with an passcode for your own use!

Rated 5 out of 5 by from It's a really great system. I bought this almost 3years ago. It's a really good system, everything still works just fine, only thing that I'm confused about. On LG tv, the volume goe's up to a 100. I don't get it bc on CD, usb 1, usb 2, Bluetooth, portable, only go up to 40. Plz example why on LG tv. It goes up to a 100, i wish it was like that for all. I wish the subwoofer was bigger. But it's still fine bc it still shakes my room. It sounds really good. I love the design of the LG it's really cool. Only thing that i wish it had. Was a tune. So I i could tune my speaker and subwoofer. But beside that Its a really great stereo I love it!!

Rated 4 out of 5 by from What ? No AM Radio ? I received my LG CM - 4550 and I'm very happy with the quality of the sound but I'm very unhappy this model has no AM Tuner. Perhaps I'm too old at 68 years but AM Radio should ALWAYS be a part of any stereo / CD Player package

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!)
