I always like the first series so much so when I had a chance to get this for free, I jumped for it.

1. No, depends on which generation of the 755 and 750, they can be the same or not. Early 750 is not the same as 755. 3. No, 750 came out before 755. I haven't seen any Sony Ericsson 2012 MH 755.

After sometimes checking, this one imho is my pick. The latters are good but I like a little more forward mid and it sure delivers.

Got my 2012 Ericsson MH750, genuine checked. Center vent, with a white round on the black filter and a hole in the center. Sound is different to 2014 and 2015 MH750. Sub bass is faster, rounder, imagination is better.

The 2014 is actually center vent. I am waiting for the ericsson one.

Found a white 14w34 MH750 with also a space typo, man Sony didn't fix it for like 3 years lol. I'm gonna pop them along with my 12 ericsson to see if both of them have side vent.

I was searching for another pair of MH750 since I love the sound of it, livelier than MH755 and just need to tone down a little bass and 3k band. Found some original 2012 pairs when Sony was still Sony Ericsson and funnily they also have the same space typo.

I just checked my 15w37 and it has the same 2 space before china. And mine is 100% not fake. So typing error also applies to genuine. My nozzle filter is also the same like yours.

Does the fake one has holograph tag brian? I'm curious.

I was going to say this. My MH750 is AG0500 has a small white dot in the black nozzle filter, however it is much smaller than the fake one here, hence my reply. Also the fake one this filter lies further into the nozzle tube, unlike the real one. The tag looks sloppy compares to the real one...

You must pop one of the driver out to check, but I think it is fake.

I got MH750 for free, it sat 5 years unused from someone who bought Z3. For now I like it more than my recabled MH755.

I listen to Jpop too, with a japanese mobile phone source, and I have no complain. Treble is harsh, yes it is, when you didnt burn in...

Now, everytime i listen to HTF600S, I see that it is far behind CKM500, though it is not a bad headphone... Next time please dont find one more which is crazier, Dave...
