This BluetoothR portable CD radio boom box is small but capable. An MP3-compatible CD player lets you play MP3 mixes that you’ve burned. An AM FM radio gives you a backup plan if you leave that stack of CDs at home. A 3.5mm aux input lets you hook up another audio device manually, while BluetoothR streaming lets you play audio from any BluetoothR-compatible device. This boom box lets you bring your music with you.
