Gonna be using it on my phone without any special powering- iPhone 6 Plus.
Yes, I know that it demands more power - such power my phone cannot supply - but from my tiny research online I've figured that the only downside to this is that the earphones will be a bit quieter - which...I don't mind , eitherway am sensitive to loud stuff so I should be fine.
So...yes? no? maybe? perhaps? ;D
