With the Panasonic SC-PMX84EG mini system, you can listen to your favorite music in various ways. The tweeters have a reach of 50kHz, resulting in the high tones accurately coming out of your speakers. You can connect your smartphone or tablet to the device, via Bluetooth. This allows you to stream music wirelessly. If you want to enjoy CDs like in the good old days, then just use the integrated CD player. If you've digitally stored your music collection, then you can use the USB input to play your MP3 files.
