[EX Q]: I have been using this exact brand and item but bought at Ulta. They are great. I got months of wear out of them. When they no longer carried it I ordered it from here. I got 2 pairs. They both did not stick to my skin at all. They couldn't be worn.....fell right off. I found them at CVS and did not have a problem with those. This was supposedly the same exact product. I'm not sure what to think but I would not recommend buying from here.
[EX A]: negative

[EX Q]: The connection with my iPhone was very smooth and easy. There is no lag and the sound quality is superb. It last days with full charge. Looks very sophisticated.
[EX A]: positive

[EX Q]: A perfect gift. I brought this coffee grinder for a Christmas present and I'm really happy to see that everything looks exactly like in the pictures. I just got it and it really looks nice - a small but solid grinder and fine, qualitative accessories. So happy with my acquisition, it's going to be a nice gift, for sure!
