Portable CD Player Bluetooth, Desktop CD Player with Bluetooth Music Boombox Portable CD Players for Home FM Radio & Bluetooth Speaker LED Screen Built-in Dual Speakers

I hadn't realized this little multifunction music player is battery operated but was pleasantly surprised. First of all, though the sound is decent, I do not use it. I connect it to a 15-inch powered stage speaker to play music that I can add drums to. The fully charged battery is still close to full charge since I got it. It is probable because I do not use the built-in speakers which are energy hogs and I use the radio very much more than the CD. I thought the radio had station presets but what it does is find all local stations and then allows sequential access to them. I have to scroll through many weak stations and stations of music I don't care for, to get to the station I do like. Since they are commercial stations I change often because of lengthy commercials. I do appreciate the size. It is so compact, it allows more room on my trap stand that holds stacks of CDs, drum keys, screws and drum mufflers that I use for low resonance turning.
