Rich and Powerful Sound with Wireless Music Streaming: If you are obsessed with sound you can now listen to all your digital music from your Smartphone via Bluetooth. This Philips Micro system also plays MP3-CDs and CD-R/RWs. It features Bass Reflex speakers for powerful and dramatic bass. Bluetooth technology allows easy wireless connection to iPod/iPhone/iPad or other Bluetooth devices, such as smartphones, tablets, or even laptops. You can easily enjoy your favorite music and sounds from videos or games wirelessly on this speaker. Bass Reflex Speaker System: The Bass Reflex Speaker System delivers a deep bass experience from a compact loudspeaker box system. It differs from a conventional loudspeaker box system because of the addition of a bass pipe that is acoustically aligned to the woofer to optimize the low frequency roll-off of the system. The result is deeper controlled bass and lower distortion. The system works by resonating the air mass in the bass pipe to vibrate like a conventional woofer. Combined with the response of the woofer, the system extends the overall low frequency sound. Audio-in and USB Direct for Easy MP3 Music: The Audio-in connectivity allows direct playback of Audio-in content from portable media players. All you have to do is plug your portable MP3 player into the audio system and you can enjoy the superior sound quality of your music over this system. And, thanks to the complete file transferability, you can also easily enjoy the convenience of accessing more digital music via the built-in USB Direct. Digital Sound Control and Dome Tweeter: Digital Sound Control offers you a choice of preset balanced, clear, powerful, warm, and bright controls you can use to optimize the frequency ranges for different musical styles. Each mode uses graphic equalizing technology to automatically adjust the sound balance and enhance the most important sound frequencies in your chosen music style.
