What a great discovery this little speaker was. I've spent £££ on really poor quality speakers over the past 10 years as I travel a lot, and by poor quality I mean both sound and build. This covers both, it is REALLY loud yet sounds great, there's some seriously deep bass in there too (although it can distort a bit at full volume). It's built really well and is small enough and light enough to carry around. I've used it a lot since I got it, bedroom, kitchen, outside over the bank holiday and as a small sound bar - i'm looking forward to taking it on holiday, it'll be great at the beach and back in the hotel. The battery life is really impressive, it quotes 12 hours but I reckon i've had more. It comes in a really good package too, gets you really excited when opening it and feels like a really expensive product. If you get this you won't be disappointed. I haven't tested the call function yet so can't comment on that. Well done Damson, show's you British company's can produce great products after all!!!!
