This Sony alarm clock was used mainly as a speaker with which it has great sound quality. It has a standard 3.5 mm jack for aux in but it also has the old Apple 10 pin connector for an older iPhone or iPod to play music through while charging.
It is also a AM/FM radio with presets and the alarm clock has a battery back up, this is powered through a cord however. It makes for an excellent bedroom alarm clock and to play music through.
