[EX Q]: I use my mobile phone constantly throughout the day for work and need headphones to so I can have both hands free. These headphones are amazing, comfortable, and a great buy.
[EX A]: positive

[EX Q]: Bought this after reading good reviews. But it’s not water proof at all. If my son has even a little accident in bed, it goes straight to mattress. I don’t see a point in having this. So I have to purchase another one.
[EX A]: negative

[EX Q]: I was excited to receive this wristlet / wallet & upon opening found it had some type of glue stuck to the exterior & one of the zippers gets hung up and makes it difficult to zip. I am returning & do not recommend this item for purchase.
