WARNING: THE COMMENTS OF DIFFERENT PRODUCT RANGE BOSE SoundTouch BLENDED, AND THEREFORE ALL DO NOT MATCH THE POSTED ON THE PRODUCT PAGE. COMMENT ON MY DOOR BOSE SoundTouch (TM) 30 Series II - Black and IT IS NOT PORTABLE. Regarding the sound, the quality is exceptional and this is what quon asked. The system easily connects to iTunes on your iPhone or iPad, which allows DInstalling and ease of use via Airplay. The application is a negative point, it would have been nice to provide control appliance from iTunes instead of using the interface is less friendly. Finally and this is very strange for this kind of mark, the finish leaves a bit to be desired especially at the rear connectors. The ports are not surrounded of a small seal so that the circuit boards are visible and therefore may end up full of dust !!! Simple design, no frills.
