I only give full stars. My ranking/scoring system does not necessarily follow the norm and is about as follows:
5 stars: The product is very good and received the "highly recommended" award from me.
4 stars: The product is very good and received the "recommended" award from me.
3 stars: The product is good/very good, but not outstanding/special enough to get any of my two awards. ["Thumbs Up"]
2 stars: The product is only about average or even somewhat below that and somewhat flawed/flawed in some areas. [neither "Thumbs Up" nor "Thumbs Down"]
1 star: The product is bad/severely flawed to outright bad. ["Thumbs Down"]
1More E1001

Review sample.
Miscellaneous:
Also commonly known just as “1More Triple-Driver”.
Luxurious unboxing experience.
I especially like the “1More” tie pin that comes included.
Nice selection of ear tips.
Shells fully made of aluminium. Unusual but nice colour scheme with rose gold and the darker of the two colours reminding me on Mercedes-Benz’ “Bornite Metallic 481”.
Build quality seems to be good.
While the included carrying case looks and feels nice, what I don’t like about it is that it isn’t designed to be fully sealed and will therefore let dust and dirt in.
Cable non-removable. Coated with woven fabric below the cable divider. Looks and feels nice and has even got some subtle blue accents incorporated, but is highly likely to fray over time and more prone to soaking fluids than regular cables.
No chin-slider.
The remote control (three buttons, located on the right hand side) feels of high quality.
Designed to be worn with the cable down. Due to this and the lack of a chin-slider, microphonics are unfortunately strong.
Three drivers per side; hybrid construction (1x dynamic driver, 2x BA).

Sound:
Largest included silicone ear tips.
Tonality:
Clearly consumer-oriented (sub-) bass-focused L- to w-shape.
As it is the case with pretty much all in-ears that house a dynamic driver and are vented, the amount by how much the E1001s’ inner vents are blocked also affects their (especially sub-) bass output. In my ears, the vents are closer to being blocked than free, and as a result the sound is even somewhat more sub-bass-oriented than if the vents remained completely free.
The bass starts to climb around 900 Hz and reaches its climax around 40 Hz to my ears, with a quantity of around 16 dB compared to diffuse-field flatness, but is already very present around 90 Hz wherefore the sound, while ultimately still focused on the true sub-bass and lower midbass, does carry some strong and noticeably punch and is also heading undeniably into the warmer direction in the lower fundamental range and lower midrange but without overshadowing the mids.
The mids seem to be neither intimate nor distant in the mix; there is small climb towards 4 kHz in the middle treble wherefore bright voices’ overtones carry a bit of added brightness to compensate for the lower midrange warmth. While this also affects instruments’ timbre (such as trumpets and pianos) negatively and colours them to a brighter pitch, I personally think that this elevation is necessary as a counterweight to the warmth in order to make voices not appear too muffled.
Around 6 kHz, I can hear a rather narrow dip that adds headroom for the former as well as the next elevation that starts around 8 kHz and peaks in the super treble around 12 kHz.
Ultimately, while neither sharp nor annoying (but sometimes just somewhat too “sizzling”) thanks to being placed quite high, the latter of the two elevations, combined with the 6 kHz drop, results in the treble to not sound natural but artificial while it sounds overall inoffensive yet bright at the same time.
Frequency Response:

ER-4S-Compensation (blocked inner Vents)
My ears block the inner vents slightly less than completely, so the actually perceived sub-bass elevation is just a little bit less strong to me but comes very close. Otherwise, that’s also the tonal tendency that I actually hear when performing sine sweeps, although I perceive the lower/mid-treble elevation as just a bit milder, with a slightly less steep 6 kHz dip.
I haven’t saved the FR measurement with un-blocked vents.

Resolution:
When it comes to resolution, the E1001 are merely “okay” at best in their price range and outperformed by a good number of other competing single-driver and some multi-driver in-ears.
That said, apart from some metallicness and perceived short decay in the upper highs, the two BA drivers don’t really shine through when it comes to details and separation; the treble just lacks some details.
Overall, the midrange and treble details and separation are just acceptable for the price, and as mentioned, more or less clearly outperformed by other single- and multi-driver in-ears in all areas or certain ones of the frequency spectrum (iBasso IT01, AAW Nebula One, Moondrop Starfield, FiiO FH1, Shure SE215m+SPE, Fidue A65 – just to name a few). Generally, it just sounds as if the dynamic driver were handling most (if not even all) of the frequency spectrum and the BA drivers were just integrated to incorporate some upper treble sparkle.
The lows are neither the tightest nor fastest and come close to the point of being spongy and undefined; solely their more or less controlled decay saves them from notes and bass lines not being perceptible anymore. As for quality, the dynamic driver implementation in the E1001 is clearly on the lower side, with only my Sennheiser IE 80, Trinity Audio Engineering Delta V-II, the NuForce NE800M and Chord & Major’s in-ears managing to deliver even less quality in the bass.
Apart from the lack of tightness and speed, I also perceive the lows’ details as less than average.
Soundstage:
The perceived soundstage is overall fairly average to me as well – neither narrow nor especially wide expanding, however with rather decent although less-than-wide front projection.
Imaging precision is okay as well – not especially blurry or diffuse, but not precise and well-separated either.

Comparisons:
Fidue A73:
The Fidue are less bassy than the 1More but still clearly elevated and warm, although a bit less warm in the mids.
In the upper mids and lower treble, the A73 are brighter.
Both are comparably bright in the upper highs, with the Fidue peaking somewhat lower.
The A73 decay a bit slower in the lows compared to the 1More but have the better defined, tighter attack as well as more detailed bass.
Both are comparably detailed in the mids and treble, with a slight advantage for the Fidue which separate single notes better and more precisely.
The A73s’ soundstage is larger and also somewhat more precise to my ears.
AAW Nebula 2:
The Nebula 2 are comparable in the sub- and midbass as for quantity, but with even more upper bass punch. The E1001 are warmer in the root, though.
The AAWs’ mids are flatter.
The E1001s’ highs appear darker due to their 6 kHz recession even though their upper treble carries more brightness.
The AAW are superior when it comes to bass speed and tightness, and also feature a more detailed midrange and treble.
Soundstage size and imaging precision are about comparable.

Conclusion:
While it lacks realism in the treble reproduction when it comes to real instruments, the E1001s’ consumer-oriented fun tuning is overall okay and does not offend. When it comes to technicalities, though, these in-ears fall rather short and deliver a performance that can be described as merely “acceptable” in this price range where several better performing single-driver models exist.
