Guided by the positive reviews I had the DS3150 / 12 ordered me. And I can also confirm the positive features: First-class workmanship, good sound quality, ... The key points, however, the disqualified this equipment for me ... It is not sufficient to cell phone radiation shielded! Although the manufacturers description of the DS3150 / 12 on this point other promises! Once an iPhone (tested with iPhone 4S) is connected, the speaker emits a loud noise by itself. This silent until either the mobile data disabled in iPhone - or the unit completely offset in airplane mode!
The DS3150 / 12 is therefore definitely advisable not to bedroom when used with an iPhone!
