Same here, except that I am in Australia and using a US->AUS plug adaptor results in a ground loop hum. I've emailed koss to ask whether another 9V 1A adaptor would fix this, if anyone else has some tips to deal with ground loop hum I'm all ears So far I've found the hum stops when I ground myself by making physical contact with chassis of my preamp, or my keyboard.
I was prepared to be underwhelmed but the ESP 95/X is su-perb. Truly.
Yes, these are in a special league, have loved mine since end of 2016 - original Koss version, but (except for the pads) they are the same. Massdrop were selling a 220V adapter early on, might have helped you out, but the selection shows 'sold out' right now.
As barondla states, folks were buying a high amperage medical grade adapter and using it to improve performance. The grounding would be excellent, don't know about international availability. I kept the link, didn't buy - now I see it is discontinued. It was from SL, model number MENB1030A0903F01. Found through Mouser Electronics. Looks like they sell to Australia, so I suggest you check their site. ME20A0903N01 might work for you, only 2A but that should be more of a high end power supply. Others may feel free to correct me, or make better suggestions. $23.43 AUD.
