The apparaige is easy. No problem in Bluetooth or NFC. My MP3 player works perfectly. So I've read that some criticized the lack button to switch from one song to another. But I do not listen to the music stuck in my ear while pregnant .. by cons, I have my phone or my player next to me and I still with my driver with music and never from the enclosure.
Let us come to the point. What is this speaker in sound? She's perfect in my eyes and my ears for the price. It makes the music all its depth, okay, not as much as the speakers that are worth several hundred dollars but for the average person, it's perfect. I could listen without problems on my playlist deezer. And also the variety, from classical. No worries. The sound is clear and nice.
I also paired my laptop to test the reception of a function call. So, no problem, the music cuts well and the enclosure becomes a hands-free kit. Very convenient for a conference call or just for everyone to hear the conversation and participate. And later, the music resumes.
The enclosure is easily recharged via a USB cable micro usb supplied by the manufacturer.
The instructions are in English but certainly it is so intuitive that it's not serious.
