The Pioneer X-CM56D is a compact stereo system that receives the digital DAB+ signal. This means you'll listen to noise-free audio, but also that you'll receive additional channels. If you prefer to listen to your own music, you can connect the system to a mobile device or computer via Bluetooth. This allows you to wirelessly transfer songs to the speakers. Briefly hold up an NFC device to the system to start a quick connection. No matter what you're listening to, the 2-way design means the high and low tones are always perfectly balanced. The power of 15 watts per speaker is powerful enough for medium-sized rooms. The speakers can be positioned both horizontally and vertically.
