I received it yesterday and have been using it for two days. If this price and performance are the same, I would like to buy two more to buy one and give one as a gift. I hope this is a product I will use for a long time and I will use it well.

They say that the microphone on the other end is weak, so the other person can hear you far away and small, but other than that, you can use it comfortably without hurting your ears.

At first, I wondered why it was so big, but it doubles as an auxiliary battery. It's convenient when you're in a hurry.
