To the naked eye the Powerbeats3 may look exactly the same to the Powerbeats2, but upon closer inspection you will notice the materials used have been improved. You will also notice the earphones themselves are a tad bit bigger than the Powerbeats 2. Both in length and thickness (hight remains unchanged). We’re assuming the increased housing is being used for a larger battery and better drivers. The Powerbeats3 sound much better over all than the Powerbeats2 in both bass, and higher pitches. We also noticed the Powerbeats3 were louder than the Powerbeats2. The Powerbeats3 claims a 12 hour battery life, but after testing we were able to squeeze out 14 hours. You can also now quick charge these earphones and get one hour of playback with just five minutes on the charger. Not bad at all! The volume rocker has also been redesigned so its easy to tell which button is which by just touching it. Theres also now a much more satisfying click to the buttons. Also thanks to the over ear hooks, these headphones never fall out while youre working out.
