How long do beats solo2 wireless need to charge?

Solo2 Wireless has 12 hours of playback after only 2 hours of charging.

Here’s how to keep them charged:

Plug in the included cable to the charging port on the right earcup.

Plug in the standard USB end to a power source—this could be your Pill, Pill XL, computer, or other device with a USB port or USB adaptor.

Charge your device!

If your headphones run out of battery, just switch to your audio cable until you can recharge.

I just bought Beats Solo 2 Wireless Gold today and when I charged them for the first time (From 0 to full), they charged in 75 minutes vs. 2 hours. Just wanted to make you aware of this. Thanks!

I just got beats solo 2 and mine has a lot more than 12hrs playback time, so far I have only charged my beats once and they have lasted about 22 hours so far, and they have only just reached 20% it's crazzzzy!
