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


Ex Input:
It's a really pretty cover and the fact that they showed what each color phone looked like under the design really helped me choose the perfect cover. It's textured on back, so it helps grip the phone and I'm very pleased with it.

Ex Output:
positive

I started listening to this series as a way to entertain me during a long daily commute. And they did entertain. Fast moving, action oriented stories. However over time the characters have also evolved. They have flaws, secrets and inconsistencies, just like ‘real’ people. This book may have been my favorite yet, I look forward to the next episode.

Ex Output:

positive
