I have the Philips BT2200 / 00 Bluetooth Box now for 2 weeks. Supplied to the box is just a USB charging cable. More is not required. The box is about 10.5 cm wide and 7 cm high. The boxes themselves are protected by a perforated metal layer, aussenrum is still a Kunstofframen. On the left is a panel made of rubber, with an on / off button (same battery indicator), + volume button - volume control and a Bluetooth display. At right is a protective rubber cover that you can deduct. Among them is charge the battery and an audio-in jack to connect any external devices (which I have not used up to now, but since I am risen Bluetooth) of the USB port. Before first use, you have to charge the battery once fully, unfortunately I can not say how long that takes, because I just overnight have the box can store, this is done on a PC or on a USB power via the included USB cable adapter I have at home anyway for such devices. First I tried to connect my phone with the box and went to the guidance. Box turn, looking at the Bluetooth mobile switching, Box in mobile, connecting ... Done. Child's play and work time and time again so quickly, I was pleasantly surprised. I use the box at the moment only in the shower, I have the box standing in the shower, so they certainly would collect water splashes, so far without problems (about 20 times Used). From the sound I was frankly surprised. The box can be done quite noisy, the minimum for the size of the box. And the sound quality I find perfectly acceptable. As I said, I use the box for showering and I can also quite easily imagine the box to take crickets etc. outside, but the sound is more than adequate, we must of course expect a rich bass or subtle sound from such a small box, that's what I did not, so I was pleasantly surprised. Conclusion: Who (especially splashproof) looking for Bluetooth box is BT2200 / 00 well-served with the Philips. I think the showers and barbecues by the lake etc. The box is perfect. One does not have to be especially careful to ensure that the box abkriegt no splash, the sound is more than adequate for such occasions and the service super easy.
