I have these boxes "twice" newly appointed and again ...... from the beginning: I have the boxes the first time connected and was absolutely thrilled -> to "creak" until after a few weeks the slave box began. So, I called Amazon, exchanges and anew. positive feeling reconnected and ??? great!!! leideer not long, the same problem again :-( read in the other reviews, no problem recognizable. So, I called again and again ordered a new pair. Back to the top again just fine, but now I had two weeks repeatedly misfires in bluetooth (have to laptop, tablet and mobile phone tries)! Now go back today; Pity, because when they are working from the price / performance ratio determined recommended. I have now for the Nupro Nubert 100 decided (although cost three times, but I hope to here but more quality) !!!
