Does the job but actual battery life is NOT the advertised 10 hours. The packaging and instructions state 5 hours of music, 6 hours of talk time and 150 hours of standby time. Actual usage time (for music) is 5 to 6 hours. The product performs well, with comfortable buttons, crisp, clear, balanced HD audio, and no noticeable audio lag when watching videos, movies, and shows, or playing games. I use this to convert my favorite wired headphones/earbuds to bluetooth wireless so I don't have to remove my headphones/earbuds every time I need to get up for something. You simply plug the headphone audio jack into this device and clip the device to your shirt or put it in your pocket (or if you have headphones with a flat cable, you can clip them to the flat cable as shown in the photo). It is small and light and can be easily charged with a micro USB cable. I chose this because I couldn't find any comfortable Bluetooth headphones/earbuds at this price point and it allows me to use any of my comfortable wired or earbuds that I currently have.
