Hi guys, I just purchased a pair of Bose QC 35 and I was wondering what you guys use to charge them. If I'm not near a PC can I use any standar USB wall charger ? Either the iphone 7 charger or the galaxy s7 charger ? The latter supports fast charging, so I'm not sure I should be using that. I also wonder if I can just plug them into my PS4 or the PS4 dock that I use to recharge my controllers. Thanks.
