Rated 5 out of 5 by from Unmatched Features I did intensive research on stereos before chosing the CM4550. The sound is excellant and it is a sharp looking design as well.

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 1 out of 5 by from Total junk! This is a horrible stereo! Sounds horrible! Shuts off it's own a lot! Do NOT buy this junk!!!!

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!

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
