You can't tell it just from pictures in the case of MH750 and MH55. There are better fakes day by day.
I ordered EO-IG955 and they looked real, no flaws at all but crap sound with 1 DD. I ordered one on amazon.de as well and got the real thing, but with distorted sound so i sended them back. When you got the real thing you know by touch are they real or not. In EO-IG955 case, cable is rubber as well as inside shell of the driver and they feel more premium overall.
In SONY case as far as i know
ALL MH1 (MH1C) are ORIGINAL. There are no fakes around. When you hold them you can feel that the cable as well as a driver is premium. Problem with MH1 is that are so many bad units, just like EO-IG955. Oluv and few others didn't mentioned this but trust me. I got like 5-6 pairs and they all sounded like BASSY MESS. Even after a few mods they didn't sound really good. Today i got first good pair and i can tell you that they are amazing and i need to mention that i payed it just 5,90e

In the case of MH750 and MH755 you just can't. If you want my advice just go with ebay and amazon. If you'r buying from amazon try to pick amazon as a seller and if you buy from ebay you should go with the best review-s. In any case if you get a fake you can get your money back. You will spend a buck or 2 more then on aliexpress or similar, but if you get a fake it's easier to get your money back.
All MH755 i got from ebay.de ware original and sounded really good. It's not a lottery like with the others and they are louder then MH1.
If you wan't my opinion, they do not sound as good as MH1 but from 5 pairs i got i could use all 5. From 7 pair-s MH1 i got, i could lisen to 1. All others are just junk, even after mods.
