These wireless earbuds has good sound quality, not the best but definitely good enough for the price you're paying. The silicone buds do a good job of “sound isolating” although you can still hear a bit of your surroundings which is essential feature for using it during my daily commute when I still need to hear announcements in the train. The battery life is actually pretty good for how the small are the earbuds. It lasts for a few hours and the case can charge it back to full. Overall size of the case is small enough to carry around in your pocket or bag. Pairing is as easy as taking the earbuds out of the case and finding it in the list of bluetooth devices in my phone.
