The LG XBOOM Mini Shelf System Model # CM4590 The first noticeable missing items are: 1. There are NO speakers 2. This LG unit does not have a headphone (3.5mm) jack for wired headphones and; 3. This system does not transmit Bluetooth audio signals. It only receives them like your Bluetooth Headphones do - so a transmitter will not work with it to send audio to your Bluetooth headphones. Because of that bit of information, I could not perform a thorough test of this LG system. Stereo System What I was able to confirm as working through my brief tests that I have been able to perform are: * That the Bluetooth paired easily to my television and iPhones * That the CD tray plays my CDs without any errors as would have been told by the display * That the FM (no) AM radio seems to function well * The volume and power can be controlled by my LG television remote control * That the USB charges my iPhone No other tests were performed due lack of speakers. Your system is rated like an 8.5 out of 10 due to store sticker residue and dusting required from being displayed for so long. Any speakers with an RCA attachment will work with the LG CM-4590 Audio FM/CD system! Guaranteed to arrive as functional!
