The Logitech S315i Portable speakers let you listen to your iPod music out loud, either at home or outdoors. You can easily carry your music with you, either at home or in the town about the rate of loss (up to 20 hours in power saving mode). Dock connector lets you listen to and download at the same time the iPhone and all iPod models. Custom, high-quality speaker drivers reproduce your favorite high and low tones accurately, so you can hear every single note brightly. Don't own an iPod? Not to worry. Speaker supports auxiliary connections through other portable music players, so you can listen to any audio source with a standard 3.5 mm stereo jack.
