Didn't work. Tried it with 3 different phones and same result. The mic worked only when held in front from ear canal, that's not how they were advertised.

Ex Input:
After reading the reviews on this product I was looking for an alternative to drinking sugary soft drinks. The problem that others have pointed out is valid. However I noticed there were many people who claimed their bottles leaked when they put ice in. That does happen. But it turned those few times into one thing after another. A couple of weeks ago my fiancee, husband and brother-in-law enjoyed a long weekend at our house enjoying our daily iced tea as well.

Ex Output:

Bad review
