Sorry for the delay in replying - I thought it was going to be a quiet day at work, so I could do some listening comparisons, but there ended up being too many interruptions. So these evaluations were done this evening in my quiet living room.
.
Connected to the single-ended output of my Onkyo DP-X1, and using USB Audio Player Pro (setting Android Sample Rate to 44100Hz) and played a couple of FLAC files from my "Iona" (UK progressive Celtic rock band) CDs "Iona - The Book of Kells - Kells" (1992), and "Iona - Beyond These Shores - Prayer on the Mountain / Treasure" (1993), with vocals by Joanne Hogg. All EQ was turned Off.
.
Comparing the vocals and treble of the **** PT15 and the **** 4in1 is interesting - considering that the PT15 is a single 15mm Dynamic driver, and the 4in1 is a Hybrid model, with an 8mm Dynamic, and a Knowles 30042 Balanced Armature - their sound is not all that different. Vocals do seem to have more fullness on the PT15 (I'm not familiar with the monk+ or ty32), and the details in the instrumental "Prayer on the Mountain" sounds a bit more natural on the PT15. As you would expect, the 4in1 Earphone, when inserted to get a good seal, has more impact in the Bass than the PT15, which is an Earbud.
.
In my under $100 earphones, the TingJie R4 ($90) and BossHiFi B3 ($29) both have good Bass; a smoother, more "full" Midrange; and a little bit less pronounced Treble. The Remax RM-600M has good Midrange and Treble, but less Bass.

Take Care,

Beware of ****.
Below are the frequency response of 4 **** UEs bought to NiceHCK along several months (raw measurements with source calibration, but not compensated; useful for comparisons, all were measured in a row, with exact same conditions; source: iBasso D14, calibrated; micro: Dayton Audio iMM-6; soundcard: Realtek ALC888).
First, comparison of 4 **** UEs (left and right averaged):
Now, individuals, left and right exposed.
**** UEs (camo):
Despite of the lows imbalance (sub-bass, 5dB at 30Hz, 2.5dB at 60Hz), these are my favorite. I love their sound.
**** UEs (blue 1):
No lows imbalance, but highs imbalance and roll-off, specially one driver (-10dB at 10KHz peak), and roll-off from that frequency (it is more than -20dB at 13KHz!). This is not very noticeable if you have difficulties to hear beyond 10KHz. No harshness in these ones, of course.
**** UEs (blue 2):
These are very similar to camo ones. Lows imbalance, but very good overall.
**** UEs (blue 4, clearly defective to my ears):
Note the horrible dip near 7KHz, and the excessive peak at 10KHz in one driver. 7KHz frequency is audible by everyone. I can't raise volume with these ones: although I'm not treble sensitive, highs are like knives to my ears, and sound strange.
When I ordered 1st ones, I received **** UE (only 1 dynamic driver, no BA) instead. Jim sent me the right ones later.
When the order of **** UEs (blue 1) arrived, after a month, they were missed in the package! I had to wait another month for them.
**** UEs (blue 3 and 4) took 72 days to arrive. And blue 4 is defective. If I want a replacement or a refund, I have to wait they check the defective one. I don't want to wait 2 months more.
So I'll never order to NiceHCK, and I'll never order a **** anymore (it's a lottery).
Super Audio 2DD+2BA. Love this IEM. Awesome bass. Neutral mid. Smooth high.
Makes me wish I'd bought them instead of the PM4. What's the price of the SA 2+2?
Edit: BTW, what do you compare them to?
interesting to see such a variation between the **** UEs. i hope my **** 4in1 that i bought during the 11.11 sale will be a good one...
i hope yours are ok, let's roll the dices.
however, 4in1 are usually reported to be harsher and more sibilance prone than "regular" UEs.
Oh man, i hope the pair of **** UES i have on the way do not have such issues!
