I really need to warn for this speaker, it did not fit AT ALL my needs! It has great sound and all the buttons etc. are clearly recognized, but the problem with it is that it turns itself off when it receives no signal!
Which is understandable for it to save power, but it also turns off when the power cord is connected. And then what it perceives as the signal can be questioned, I listened to examples of Pulp's The Day After the Revolution, and the end understood it as quiet as most are not.
I googled the problem and people seem to have problems with, for example, classical and ambient music, that it turns even there. Nor is it possible to turn off this feature. If you like to listen to hitpop or type machine works safely good ..!
Returned it and added a couple hundred pieces and bought the Philips DS7550 and how satisfied anything with it!
