Hidizs MP145 IEM Review

[agpanoz]

Are those tips included in the box or sold as a separate kit?

Included in the box. They arrived with the rose gold attached and I’ve kept them on so far.

I confirm that they are included. I use the red ones.

@agpanoz @InfiniteJester

Thanks. I really want a pair of these but that video of the differences when cut in half scares me off a bit.

They were included in the box.

 

[Mr Swing King]

There is an opinion of Andy which I trust and talk about the sound change by the way

This reminds me of when Beyerdynamic released the T1 2. Gen in black. Suddenly folks were hearing all kinds of differences between the two ie the black version was warmer compared to the original gold one.
Measurements told the rest of us that it was the same headphone.
We hear what we see.

I think Hidizs put much thought on iem cable for the MP145. I've tried NiceHCK MixPP and NiceHCK GrKing 7N Silver Plated OCC+Graphene OCC but still the one came with the MP14 is still the best sound.

How did you evaluate the “sound” differences between these cables?

 

[sulfuriq]

Both NiceHCK cables gave me fatigue/headache on Low Frequency as Bass overwhelmed or bleed into the mid frequency. The original cable is have more clarity and details. I ran it on Bit Perfect (UAPP) on these:-
1. Hiby R4 (ESS) + ifi Hip DAC3
2. OnePlus 7T + ifi Hip DAC
3. OnePlus 11 + Lotoo PAW S1

How can you tell whether or not these ‘differences’ are down to real sound vs something that you’re imagining in your head?
A simple blindtest will narrow that down.
I have seen people who were extremely confident in themselves and their ability to distinguish between different cables, yet when the cables were wrapped in cotton balls and some duct tape in order to mask which was which…no one could tell the difference.
I am not saying that you don’t hear a difference - I believe you do. I just think it is your mind playing tricks on you. I’ve been fooled similarly in the past. The mind is a powerful thing.

Yes, it is real and no duct tape involve. Try it yourself. With the original cable I can listen to music for hours without any discomfort.

I think you misunderstand
What I am saying is that when sight is involved in the process, we really can’t be sure. You know which cable you are listening to at all times.
If you really can tell which is which, you would be able to in a blind setting as well.
Most cable afficionados believe they can…but the truth of the matter is, that when they can’t see what is playing, the differences simply disappear.
Like I said before; the mind is a powerful thing. We need to implement some form of testing in order to rule out bias, and that is where blindtests come in

No problem. Like I said before try it for yourself, borrow some cable from your friends and do the listening test on the DAC/AMP you have and the same songs that you are listening to.

 

[Mr Swing King]

I have on quite a few occasions. Cables don’t make any sort of audible difference unless there is something genuinely funky going on.
It’s alright though. I have satisfied my own curiosity with regards to these matters, which is why I often recommend listening to gear blind. I would rather people focus on things that do matter in this hobby opposed to spending money on fx cables.

 

[sulfuriq]

Spending cables for replacement as MP145's cable is quite thin and easily broke. By the way those 2 NiceHCK cables are cheaper than the one came with the MP145.

What @Mr Swing King tried to explain you—in a very nice & respectful way—is that, as long as you have both hearing and sight (you can “see” which cable is being used), the test is automatically invalid: you can’t determine whether the difference you perceive (nobody is going to question your perception) is due to hearing a difference (the sound…) or seeing a difference (you can see which cable is being used…). You can’t state the difference is real until you control all your test variables…

Like I said before try it for yourself, borrow some cable from your friends and do the listening test on the DAC/AMP you have and the same songs that you are listening to.

Ok, I’m willing to try for myself…

Your difference criteria is: “fatigue/headache on Low Frequency as Bass overwhelmed or bleed into the mid frequency.”
How do you define “fatigue/headache”? You need to explain this in objective terms so that I can try for myself…. What fatigues you may not fatigue me and I may not experience the same headaches.
You mentioned in a previous post that you can easily fall asleep wearing the MP145. Was one of the cable tested when you were falling asleep, whereas the other were tested when you were listening music and, for example, reading a book? That would be another uncontrolled variable…

How did you determine that the fatigue/headache was due to “low frequency”? I see that one of the sources you used was the HiBy R4. This DAP has a system-wide PEQ: did you try a low-shelf cut in the bass to see if the fatigue/headache was still present with the NiceHCK cables?

What does “bass overwhelmed or bleed into the mid frequency” mean? Some kind of IMD? How did you assess that? Measurements? Again, I’m willing to try for myself, but I have no idea what it means.

Spending cables for replacement as MP145's cable is quite thin and easily broke.

The cable is thin and breaks easily…. Now that’s a very good reason to look for another cable… Just so that I have some reference: how many MP145’s cables did you actually break? Over which time period? How many hours of listening approximately? How many insert/remove cycles approximately?

I apologize if you feel offended by my questions. It’s not my intention… but please, add a disclaimer that your comments are subjective when they are… And if they are not, and you state they are real, provide a little insight about your test methodology and how you conclude your observations are real.

First of all, I the one that test the cable and I who fell the fatigue/headache because of the overwhelm low frequency the bass after listening for an hour.
The cable that I used to fall asleep is the original one as stated on the July 5th post.
And I did mentioned that all 3 cables were in the Bit Perfect, nor did I use PEQ/EQ or EQ or any DSP. DAP is not the questions here as I mentioned 3 DAC, ESS (Hiby R4), Burr Brown (Hip DAC & Hip DAC3) and Lotoo PAW S1 (AKM) with my OnePlus7T and OnePlus 11. All in Bit Mode through UAPP. All my listening I never use any DSP or PEQ or EQ and those 3 are my daily rig.
So is there a problem looking for a backup cable for the MP145? Jezz..
And yes it is my observation for something that familiar to me, the songs, the rig, of how I use it as I have been using MP145 for months now and I familiar with the sound signatures it makes with my DAC and Songs.
Or did I make a disclaimer that changing cable improve the sound quality?
The questions is, have you even try to swap cables for your MP145 to make an observations?

Ok, so it’s your feeling…

No problem whatsoever in looking for a backup cable…

The only “problem” was your original statement:

I've tried NiceHCK MixPP and NiceHCK GrKing 7N Silver Plated OCC+Graphene OCC but still the one came with the MP14 is still the best sound.

You’re the one who “feels” it… it’s your observation… Fine! It’s just a subjective opinion. Valuable, sure, but subjective.

I actually use my MP145 with another cable—Moondrop FreeDSP—and in my subjective opinion, it can make a hell of a difference !!!

Not valid as it uses DSP with USB-C plug though

 

[CedarX]

And why does it invalid my opinion that this cable can make a hell of a difference? Do you think I should control the test main variable (the DSP)?

 

[sulfuriq]

You should use the same plug as with the original cable
