I bought these as a gift for a friend's birthday. He really wanted AirPods but those thing are over $100, and these were within a gifting price. He said they sound great and are comfortable, and they pair quickly to his phone. He seems satisfied - great earbuds and great gift idea.

Easy to use mic for phone/pc/laptop. Great if you just need a small mic and don't want to spend a lot of money. Works well. Comes with velvet carrying bag. *disclaimer: I received this product for free in exchange for my honest and unbiased review*
