I bought it on Amazon and tried to use 'Replacement' option so they could send me a new pair, but every time I tried it, I got Unknown Error and was left with only return cash options. So I went with that and just made a new order. I still haven't send back broken one's so I will have time to compare them. I also had 2dB lower volume on left cup, but I measured it with my phone, so not sure how accurate it was, but it was consistent between trials. But since I haven't heard difference personally(maybe my hearing is bad) I didn't mentioned it before.
I can't find any shop in Poland or Europe that have them, and when ordering from America, they just cost way too much.Aeon RT
