I use the speaker only in conjunction with my Samsung Galaxy TabPro 10.1. Both have Bluetooth 4.0. The Tab is the speakers within seconds. The telephone function I have deactivated The connection is absolutely stable even in 5 m distance with obstacles. The handling is absolutely simple. Loudness differences between BT and. Cable I can not confirm. Absolutely. Where the supplied cable with 68 cm Length in connection with a tab on the lap is not useful. But my own 3m cable makes no difference. What makes difference is, as already described here, the choice of location. In the wall or furniture corners of the sound is more voluminous than in space on the table center. Generally, the sound is much better than the tab speaker. What is most important to me at the speaker: the volume. Just like the Tab can I between level 1 - select 15. The low levels are best, as sleep aids for children. For me, the speaker level 14. (1 plays under max to provoke any overload.) Tab stage 10 is then loud enough for listening to the radio in the background.
But even both at level 14 is not as loud as you want it to hear his rock / metal Favoritses. (Then equivalent to about stage 9 at Tab with my in ear) And if I do not write really loud, then I put the well in relation to the size. I do not expect this to be able to like my column speakers provide sound the whole street. Its strength is its smallness for the ride on the road, but at home I would double the amount of 50% more Wish volume at twice the price in the same size.
