Intro

Much has already been written, analyzed, hyped and warned of fakes about the MH755. A little mustard from me doesn't make any difference anymore, but I'm in the mood for it.

An incredibly cheap in-ear, which not only serves as a dummy, but can easily compete with much more expensive models.

I belong to the lucky ones who have acquired a seemingly original model and now I would like to share my experiences with you.

Handling

It is difficult to find something here that could be positively emphasized. Otherwise, one must of course also ask oneself what one would like to expect for 3 €.
One thing is certain, the MH755 was not intended for retail sale, but only as a supplement to music players from SONY. Therefore, no packaging or appealing content is to be expected.
To make it short: There are 3 pairs of silicone tips in a clear plastic bag, along with the in-ears. That's it!

I have to question myself again and again, if SONY wasn't aware of the treasure they found/developed there. Because as carelessly as they dealt with the product design, it suggests that this should simply be a temporary supplement to their products, which is mostly replaced by private in-ears anyway by customers.

The cable is as useless as it is cumbersome. Starting with the Y-split, the right cable is longer than the left one, because you probably want to run it behind your head to fall down on the left side of your body. In general, the cable does not measure more than 50 cm and is therefore only usable if you carry the music player in your breast pocket or clip it to your shoulder bag. This may just about make sense for Bluetooth players, but for any other use it is simply not usable.
Of course, you will search in vain for a remote. The plastic case also doesn't make a solid impression and can be opened with finger force without any problems.

If you leave the cable out of consideration, the MH755 is very comfortable to wear, probably the only positive thing here, along with the decent isolation.

You can find many instructions on the Internet on how to replace the cable, or even convert the MH755 to a MMCX connection.

Sound

Hello Mr. HARMAN, good to hear from you!
The tonal concept is as simple as it is brilliant. A dynamic driver that almost hits the HARMAN curve. No more frills, like a chrome-plated acoustic chamber, golden sound tubes, or alien technology as a filter. You could also put the driver into a hollow stone and put it into your ear. It would make no difference.
The bass is more boosted in the subrange than in the midrange. Although it has a high weighting in the signature, it doesn't seem overpowering or overly puffed up. I like this kind of bass where not the complete focus is in the punchy midrange bass, but in the best case you can feel the bass deep.
Yes, the bass has a strong presence, but one that brings a smile to your face rather than deterring. It doesn't miss the accurate bass reproduction, but scores with details and naturalness as well as the right dose of punch and pressure.

The mids are quite conventional in their presentation. Raised upper mids and rather lowered lower mids. This shifts the focus a bit more towards female voices, or guitars, but only to a very manageable degree. In other words, the mids are just as well able to reproduce male voices or strings voluminously.
The push in the upper mids and the vivid highs combine warmth from the bass region and brightness, resulting in a very natural sound, with well placed voices that sometimes more, sometimes less push to the fore.

The trebles don't have the greatest extension, but manage to create a very homogeneous image within their capabilities. They bring some brilliance to the top end and create an open space where the individual sounds can develop freely. In rare cases they can become a bit exhausting together with the midrange push. However, it never becomes borderline, or unpleasant. They are also very relaxed when it comes to sibilants. Here I actually find in-ears like the MOONDROP STARFIELD, or TZF No.3 a bit more exhausting, especially in the upper midrange. But the STARFIELD for example is a bit finer in its tuning and resolution. In addition, the MH755 can be a bit tinny in exceptional cases and eventually get fatiguing in the end.

It's impressive what the MH755 can mix with simple ingredients. This is true not only in terms of sound, but also in terms of its 3D imaging.
What you also have to give the MH755 credit for is its stability of output level. With such cheap in-ears you usually have the phenomenon that as soon as the bass turns on, the sound completely falls apart. This is not noticeable here at all. As soon as the bass of the MH755 unpacks its muscles, this doesn't affect the joy of playing the mids or trebles in any way, but they form a homogeneous symbiosis.

Outro

With the MH755, I certainly didn't find an insider's tip anymore, because the outstanding sound characteristics of the MH755 are well known.
What is important is how to handle it, because in its original form the MH755 is hardly usable in everyday life.
At least a cable extension is appropriate, which can also be purchased for a good 3-4 €.

In terms of pure sound, the MH755 has an enormous potential, which it knows how to exploit. Here I have no problems to call it together with a TIN HIFI T4, or MOONDROP STARFIELD.
However, it is a total failure in terms of product design, which is a pity. If SONY would consider to pack the driver in a design that is suitable for everyday use, nobody would be angry if the MH755 was offered in a middle double-digit range.

Legend

Haptic:

Here the processing plays a role and the usability of the scope of supply. Additionally the appearance, wearing comfort and robustness.


Value:
Here I evaluate for me subjectively the price/performance ratio - does not flow into the evaluation!

Z: No Brainer

A: money well spent

B: all right, you can do

C: gives better for less money

D: overpriced

E: collector's price

Daily life:
Here, I focus on the long-term audibility and whether I can hear it well out of the box. This is of course very subjective and therefore only a minimal deduction or bonus.
