Intro

After the MH755 we come to the next positive accident of SONY. The MH1 is also a very cheap single-dynamic in-ear, which performs better than much more expensive headphones.
All in all, the MH1 is the braver of the two with the slightly stronger V-signature and a step forward in terms of handling.

Handling


As with the MH755, the MH1 was/is not intended for retail sale, but as a supplement to various music players from SONY. If you want to buy the MH1, you will get it exclusively in a bag with the original silicone tips. There is also a cable clip.

The isolation is very good and almost no noise penetrates inside (when the music plays). This also applies to the environmental sound system.

Critical point here is the cable. The remote is mounted a bit too high up and the cable noise is extremely annoying, which makes it not particularly suitable for sports and other activities. Again, there are plenty of instructions on how to replace the cable to deal with the problem yourself.
But what makes it even worse in everyday use than the MH755 is its sole compatibility with SONY ERICSSON products, thanks to the integrated remote, which has a different pin assignment than usual. In addition, the cable is asymmetrical, as with the MH755.

The wearing comfort is excellent due to the compact design. The metal housing also makes a robust impression. The MH1 has this clearly on the plus side compared to the MH755.

However, if you have the opportunity to purchase the MH1C, you will have compatibility with all devices. The cost is around 10 € on eBay, up to 20 € even on AliExpress and the cable is still not really usable.

Sound

Mr HARMAN also sends his regards to the MH1.
This makes him a very pleasing in-ear and an excellent all-rounder.
As with the MH755, the bass also has a boost in the sub-range and gives pleasure with a pleasant beat and pressure. Compared to the MH755 it is the slightly warmer and not quite as tight. I think it's a success all around, I just wish for a bit more speed. It leaves the mids alone as far as possible, but can't quite keep its hands off them.

The result is that the mids are pushed back more compared to the MH755 and voices sound a bit more distant (men). The peak in the upper mids is also more relaxed, which makes the mids appear smoother and somewhat warmer. Nevertheless, they are still able to reproduce details with a good resolution and transparency. In comparison to the MH755, it lacks a bit of liveliness. In return, this also has a positive effect on the audibility.

The highs are just as relaxed as the mids, with a good but manageable extension. They still manage to clean up the signature a bit and provide clarity and airiness. They neither have unpleasant peaks nor do they become tiring. Equally skilful is the avoidance of sibilants. I find the highs of the MH1 more harmonious and natural than those of the MH755, so the point here goes to the MH1. In terms of details, both are on a par, with the MH755 being brighter.

In the width of the stage, as well as the separation in the panorama picture, the MH1 and the MH755 do not really differ. Both perform here in a very good range.However, the MH755 wins in height, and slight advantages can be seen in depth.

Outro

The MH1 is twice as expensive as the MH755, but not twice as good!
Joking aside, the MH1 can be found for 6 Euros and just like the MH755, the price/performance ratio is a joke when it comes to sound.
If you are reasonably technically gifted and want to take the trouble to replace the cable, you get a very good in-ear, which is not only comfortable, but also has all-rounder qualities. This makes it the perfect buddy for everyday use.
Without the modification this is unfortunately less true due to the cable noise and the cable is also only compatible with SONY ERICSSON products.
I see the MH755 slightly in front due to the somewhat more present mids, but the MH1 has the safer tuning and better audibility. It's hard to accuse it of gross errors and the MH1 is fun to use because of the good sub-expansion.
The MH755 is a bit more lively, the MH1 more relaxed and natural.
In the CHI-FI area there are some very cheap in-ears, some of which are really good (EZAUDIO D4), but what SONY has done here with the MH755 and MH1 is remarkable, whether they are aware of it themselves or not.
If you have the opportunity to get your hands on the MH755, or MH1 in the original, you should take it.

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.
