I was with the BT3500 found looking for a portable speaker are on the go and I got him! The design is super classy (in Flask Style :-), performance and especially the price is right. The connection to the mobile phone (iPhone 4S) was made without any problems and the sound has also surprised me equally positive. The treble, mid and even the depths are clearly played. The volume can be regulated at either the phone or on the beautiful, large volume knob on the unit. Also important was my strong battery. Accept a phone button for conversations is also super convenient.
I briefly machs: as bekennder Philips fan I would express a clear Kaufempehlung!
