Sony's Greatest Accident: the MH755​

Introduction

The Sony MH755 is probably the most obscure "popular earphone" that I've seen. I've never heard of it beyond some bare whispers in some dark corner of the internet, and yet it generates enough buzz and respectability to the point where it has its own booming market of fakes (watch out!). It is an unassuming little thing; it looks like something I'd find at the bottom of the bargain bin at a dubious electronics shop in Chinatown and feels like it'll snap in half if you just look at it in the wrong way. I probably wouldn't have paid it any attention either, until someone handed me one to try out.

The bad

The overall signature is pretty close to the Harman target, though I'd personally describe as somewhat V-shaped. The upper midrange can get intense and forward for my ears, taking focus away from bowed strings and male vocals and shifting it towards plucked instruments and female vocals. This emphasis in upper mids and suppression in lower mids results in a shouty and rather lean signature, which can be a deadly combination for many ears. Imaging is little closed in though still what I'd consider within the realm of "average"; completely expected for an IEM.

The MH755 also seems to struggle a little with extension in the highest registers, which can kill a bit of air in your listening experience. Cymbals aren't exactly the most natural sounding instrument in its arsenal and can sound a little blunted depending on the track.

The good

Taking into account all the things I've tried and owned over the years, the MH755 is... very good. The resolution is solidly in the upper echelon of things, the notes are clean, the attack is nice and sharp, the decay is naturally "DD" and the bass is focused towards the lower sub-frequencies which strays clear from midbass bloom and bleed. It won't make me throw away my kilobuck customs, but I'll be more than happy to have them as my daily drivers for months on end if I have to. I can't even say that for most IEMs I've tried.

I know I should be writing more than this but that's really all there is to it. There is very little I can nitpick on; the MH755 is a U-shaped, dynamic driver IEM that performs at a high level and doesn't do anything particularly wrong. And given my standards, that is rather surprising to write down.

Conclusion

Realise that not once have I mentioned the price. At this point it is completely irrelevant. Everything I've just said was in the complete absence of price points; it could be $3 or $300 for all I care.

Usually at this point, I'll drop a letter grade that serves as a comparison point for where I believe the IEM performs in. In this case, I shall exercise my right to not do that. Well, not publicly at least. I believe in telling the truth whenever possible, though sometimes the truth can be so outlandish to the point where it may be better not to speak of it at all.

At the very least, you can take my words at face value. The MH755 is an IEM that serves as a challenge to my preconceptions on what a budget IEM is truly capable of. It is truly an accident in the most positive sense of the word, and I yearn for the day that another rises to challenge me once again.

I don't think MH755 (and MH750 which should be the same but with a longer cable) can be qualified as accidents as they use the same microdriver tech as the once hyped to death MH1 if I am not mistaken. To me they are decent enough, even good, and I prefer them to the MH1 if only for the improvement in fit and cable microphonics.

Would be curious to know the rating but I guess if it's too high there is a risk it'd damage your credibility so I am guessing the ranking is withheld for fear of this happening.

The one that I'm currently using is a loaner with a 2pin removable cable mod (no sound mods) so it's not really representative of how the actual unit should look like. I did however buy a Sony SBH56 Bluetooth receiver so I'm at least guaranteed a genuine unit later on (the SBH24 also has a MH755 but Black Friday made the 56 cheaper so I went for that instead).

I did read up on that here, apparently the MH750 has more subbass and closer to the typical FF/DF target curves in the upper midrange. My friends also tell me that there is a small difference between the MH750 and 755 so I'll be testing that theory out once I get my hands on both.

I read somewhere that there are a lot of fakes for sale on the MH750 and 755 (especially on eBay) so buyer beware...
