Just what i was looking for. At first i had my doubts about these headphones before buying them, but after receiving them, i'm really satisfied! The speaker quality is amazing, and so is the sound quality in the earbuds. It's comfortable, it sounds great on calls. It's great overall and really makes my life at work easier. No tangles or anything, i'm able to move and go throughout my day listening to music or chatting.

Ex Output:
positive

This wig started out beautifully. Then it started shedding three days later. After shampooing and conditioning according to the instructions it became a stiff mess .The curls were no longer bouncy. It is dull, stiff and lifeless. I have lace front wigs I paid less money for that are still beautiful after 6 months and several shampoos. I am so disappointed with this purchase! I will never purchase another wig from Amazon!

negative

POOR Quality! Cover ripped, 1/3 of the book is water damaged. It was represented as "very good quality", but there is no way this could be considered anything above poor or unacceptable condition
