Thank you for your recent question regarding our Home Speaker 500.
This Home Speaker is auto sensing 100-240 V, at 50-60 Hz. As such, provided you're using the right power ports/cables, this can be used in countries within this voltage range.
You can connect to this system through Wi-Fi, Bluetooth or directly via AUX. If you use Bluetooth or AUX, you can pair to a computer and play any source onto the system (downloaded music, video players, online sources etc.). If you use Wi-Fi with our Bose Music App on a mobile device, you can access internet radio stations through our Tune-In service.
We hope this answers your questions!
