Well… it is time have a head to head comparison (and some recommendation) between what I consider the King of single dynamic driver based on my collection (joint spot with the Beyerdynamic Xelento depending on the listening mood I am into
…) the new Sony
MDR EX1000, and the new Sony flagship IEM the
IER-Z1R.
For those who prefer a straight to the point approach, here is a summarized conclusion; the IER-Z1R are not what I expected nor imagined as successor of the EX1000, nonetheless, they are a worthy successor although they share very little in common. This does not mean that the EX1000 are now obsolete, it just mean that Sony trial and error with Hybrid configuration through the XBA series in the last few years, has finally yielded an IEM that in my humble opinion feels at least as engaging as the EX1000 with overall better sound definition in a more laid back tonality.
For further analysis, please refer below:
Before I commence, never thought of doing the comparison this early… but since my family left me alone for a school break vacation, and due to
ProF3T1 recent request; here I am in a Café having a meal and typing this out. Note: apologies for the less than optimal lighting on upcoming pictures.
Without further a due, let’s start off with finding out the impedance and sensitivity of the IEMs for source volume matching:
· Sony MDR EX1000: 32ohms and 108 dB / mW
· Sony IER-Z1R: 40 ohms and 103 dB / mW
Since the difference is not that significant (especially in an outdoor environment), I will use the same volume on the Sony WM-NW1Z (Volume:60-70) for the 4.4mm balanced output comparison and on the Onkyo DP-CMX1 (Volume:30) for 3.5mm unbalanced output comparison on Tidal music.
Disclaimer: Below are just subjective impressions, based on my personal listening preferences and experiences.
Sony WM-NW1Z + DSD and FLAC files (Album, Track / Artist)
Note: Used the 4.4 balanced MUC-M12SB1 Sony cable and MMCX to EX1000 adapter for comparisons below.
1. 3D imaging and sound stage (Dark Side of the Moon-DSD, On The Run / Pink Floyd)
Imagine being blindfolded and watching a movie drama scene without any dialogue, this is what “On The Run” track is to me.
With the EX1000 the image is very vivid and gives you suspense throughout the track, this is due to more forward a brighter tonality coupled with wide and high stage dimensions. Feels like you are sitting in front of a good quality home TV with good speakers. On the other hand, the IER-Z1R makes you feel like you are sitting in a cinema in a darker room with increased stage depth. Hence, sound might not be as vivid but better defined.
Personally, I prefer the EX1000 rendering on this track, even though purely from X, Y & Z axis the IER-Z1R has the upper hand.
2. Pace, Rhythm and Timing “PRaT” (Dream Theater-FLAC, Enigma Machine / Dream Theater)
My interpretation of PRaT is what sounds desired to my ears in terms of Pace, Rhythm and Timing, will try to explain through “Enigma Machine” track. First, I would like to introduce you to Mike Mangini and is drum set for “Enigma Machine”:
Impressed?!?
Well… back to PRaT; in this case, I try to imagine that I am the drummer (know nothing about playing drums), nonetheless want to deliver the track to the audience based on what I recognize as ideal Pace, Rhythm and Timing.
The EX1000 does great in conveying the energy transmitted by hitting all the instruments clearly with perceived slightly quicker notes decay. Nonetheless, I prefer the PRaT on the IER-Z1R because it sounds more natural and even though it might be perceived to be slightly slower in notes decay, it is outweighed by improved notes definition and perceived slightly better instruments positioning, and thus, Pace and Rhythm is personally more desired.
3. Sub-bass & Bass (XXYYXX-FLAC, Alone / XXYYXX)
Throughout the track, the bass and sub-bass is easily recognizable. The EX1000 bass and sub-bass is tighter and punchier (magic of DD bass which is difficult for BAs to match), and to my ears goes deeper than the IER-Z1R. Note that on the WM-NW1Z balanced connection the IER-Z1R bass and sub-bass becomes tighter, than but not as punchy as the EX1000. Nonetheless, on this track the IER-Z1R has better transient between bass to sub-bass.
On bass and sub-bass, I give it a draw, as I love both presentations depending on the different genres of music I listen.
4. Mids – Vocals (21-FLAC, Someone Like You /Adele) & (Hybrid Theory-FLAC, In The End / Linkin Park)
Let’s start by saying that mids, especially vocals are not the forte on both Sony IEMs. How I wished them to have the Fitear ToGo334 mids. What I try to feel is the emotions emitted by the singers, such as Adele’s disheartened voice or Chester Bennington’s tireless singing (R.I.P.).
Having said the above mentioned, the IER-Z1R mids are more recessed compared to the EX1000 yet more than sufficient in conveying the lyrics clearly, while the EX1000 forward upper mids gives a more energetic presentation. However, neither of them really hit the marks in terms of intimacy.
If I really need to pick one of the two, I will chose the EX1000.
5. Treble (Dark Side of the Moon-DSD, Time / Pink Floyd) & (Hotel California-DSD, Hotel California / Eagles)
Here is the real fun; these two IEMs could not have been more different yet complementary (assertive vs. easy going). It is a real Love or Hate preference, yet it is my favourite feature of the IER-Z1R.
At the beginning of “Time” track when all the clocks ring one after another, in addition of getting your hearing sensors running wild, at the end there is a mechanical sound on the left channel which is difficult to clearly distinguish in, I dare to say less technically sound IEM. While in the last one and half minute from “Hotel California” track, the cymbals and hit hats on the right channel might sound harsh depending on IEMs treble tuning.
Let’s say if you were sleeping and you had the EX1000 in your ears and the “Time” track was played, you will probably be jumping out of bed in an instant. While, with the IER-Z1R, you will probably roll around your pillow a little longer and wake up in a more relaxed mode J. As for “Hotel California”, the cymbals and hit hats in the IER-Z1R sound more natural and better defined than the EX1000, which sounds brighter and slightly splashy. Both are able to convey the tiniest of details.
The thing that impresses me most with the IER-Z1R treble is the way the treble is accentuated when the track needs it, and extended when you least expect it while perfectly married with the warmer tonality of the IEM. Imagine, you are standing at the beach shore, and since it is a very calm day without much wind, the waves hitting your lower legs are expectedly mild; suddenly, you see a bigger wave coming and you expect a stronger impact, but when this wave hits you unexpectedly step backward because you did not see it coming.
Onkyo DP-CMX1 + Tidal
I am borrowing some writing previously done when comparing the Empire Ears Legend X, Spiral Ear SE5U and Spiral Ear SE6. One of my current reference track on Tidal for such analysis is Alan Walker’s “Faded” track in four versions, as follow:
1. Original:
2. Instrumental:
3. Restrung:
4. Piano: *sorry could not find the official Piano version on YouTube
1. Original version – This is the most demanding of the four versions. The electronic instruments are coming from all directions lows, mids, highs, left, right, front and back; while the female vocal is at the center. If the IEM does not possess a stage dimension allowing right balance of notes separation and resolution, the track will sound too congested. The ideal sound I am looking for on this track is an energetic sound, where my mind is immersed to the melodies while listening to the vocals.
2. Instrumental version – This version is the same as the Original version, but without the female vocals. If the IEM, does not have a more neutral frequency response, you can identify which particular area of the sound spectrum is emphasized. The ideal I am looking for on this track is the same as the Original version, but without vocals I am able to focus more on following the 3D imaging of the electronic notes.
3. Restrung version – This version is probably my favourite, as it is basically the acoustic version of the original (piano, violin, cello and etc.); while the female vocals takes center stage and becomes more intimate. Since the tempo is slower, intimate mids, resolution and detail retrieval is what I look from an IEM. The ideal sound I am looking for on this track is being immersed by the angelic voice of the singer, while the acoustic instruments perfectly blends and supports the lyrics.
4. Piano version – Well, very pleasing and laidback track nothing but the Piano from the Restrung version. The IEM, which conveys sounds to feelings with realistic tonality and notes decay, is the winner. The ideal sound I am looking for on this track is a smooth and romantic tune, which the piano notes, comes alive.
Comparison:
1. Original version ranking: EX1000 = IER-Z1R
Tried my best to find the winner, but on this track, I preferred the bass of the EX1000 which are punchier than the IER-Z1R, with sparkler treble and slightly less recessed mids compared to the IER-Z1R.
However, although the width and height of stage between the two IEMs are similar, the depth on the IER-Z1R imaging coupled with more musicality on the IER-Z1R made the vocals sound more distinct/separated, made me tip the “weight scale” back.
2. Instrumental version ranking: EX1000 > IER-Z!R
This one is an easier one for my preference. Because of the above mentioned tighter and punchier bass and sub-bass, in the EX1000 the track is presented in a diamond/rhombus shape leaving the center mid (vocals) empty. Unlike the IER-Z1R where the bass and sub-bass sounded more elevated, slightly bleeding it into the center mid.
To note though, the EX1000 more aggressive treble presentation compared to the more natural presentation of the IER-Z1R, might prompt people to prefer the latter IEM.
3. Restrung version ranking: IER-Z1R
>EX1000
This is a matter of preference between brighter tonality versus more natural tonality. The IER-Z1R mids are slightly more recessed but it is compensated by increased depth in stage, on the other hand because the EX1000 have more clarity in the upper register resolution and detail retrieval are presented differently.
My slight preference goes to the IER-Z1R as acoustic instruments sounding more natural.
4. Piano version ranking: IER-Z1R>EX1000
This track was the easiest one to pick. On the EX1000 the upper mids made the Piano notes decay sounding less natural; on the other hand the IER-Z1R were more intimate and the notes sounded more realistic.
Other non-sound related comparisons:
- Sony MDR EX series cable connector locking system still the best in class (really wished they carried on the IER future series)
- EX1000 are more comfortable to wear for longer term listening (except for nap time), but the IER-Z1R provides much better isolation
Conclusion:
Finally, after years of waiting for a worthy successor of the Sony EX1000 has come, in this context the meaning of successor is not an IEM that does everything the same way but better than the predecessor does. Rather, from sports/entertainment perspectives think about:
- Michael Jordan vs Lebron James (Basketball)
- Arnold Schwarzenegger vs Ronnie Coleman (Body Building)
- Friends vs The Big Bang Theory (TV series)
Different yet great in their own rights.
The IER-Z1R is NOT recommended to:
1. Those who prefer brighter tonality like the EX1000 (personal King of 1 DD IEM together with the Xelento)
2. Those who prefer a neutral tonality like to KSE1200/KSE1500 (personal King of neutral reference IEM)
3. Those who prefer a mid-centric signature like the Fitear ToGo334 (personal King of 4BA IEM)
4. Those who never invested for TOTL IEMs that cost more than USD1,500
5. Those who have smaller ears
6. Those who prefer less fancy/more subtle design when wearing IEMs in public
On the hand, strongly recommended to:
1. Those who do not mind a slightly U shaped signature, albeit hearing all details in a darker/more laid back tonality/signature, in an above than average stage dimensions (X,Y & Z axis)
2. Those who are collectors or Sony fans like myself…
