Anyone who posted that this was difficult to put together should probably not be paddling a kayak unsupervised. Thank you so much and I would definitely buy these again. (EDIT: Der Fehler lag darin, dass mein Gerät sich im Bluetooth Modus mit den anderen gekoppelt hat und nicht im Intercom. JBL should provide some fix immediately. Even when I place them high on my skull, the audio comes through very well in a quiet environment. These shoes are extremely comfortable and light! Sized up after I received the first order and they were too narrow. The ?door? is a little flimsier than I was expecting but still good quality. All in all a good fairly protective well made case. I bought these for my CNC machine but the t-bolts are too big to fit in the tracks of the table,
