Perfect fitting case that is made of neoprene and a good protection against scratches, eg when transporting the speakers in a backpack provides. It is not particularly thick, so it can protect from the outside only on light to medium pressure. A zippered compartment on the outside half-height can accommodate cable. The relatively large battery charger can be here however not accommodate - on the other hand also little reason to deny the charger loose to stow in your backpack.
Too bad that the bag can be only selectively with respect, Denon should offer the speaker better in the set with this bag. Alternatively, you can also a good 10 to 11 inch notebook case neoprene manage that then certainly far less precisely, but have typically for 1/3 of the price (Addendum: I paid 29.90 euros and was glad to refer the original pocket at all).
