BLON BL-01 Review (1) – Another BLON!? Aerosmith Says No More No More!!!
Pros
Well built metal shells.
Smooth and non fatiguing tuning.
Good timbre.
Above average isolation.
Good price to performance ratio.
Cons:
Iffy fit (slightly better than the fit of the infamous BLON BL-03).
Same crappy accessories (stock eartips/cable).
Not the best in technicalities.
Midbass bloat, might be too bassy and warm for some.
May not be getting full potential with low powered smartphones, amping is needed to scale the IEM.
EXECUTIVE SUMMARY
The BLON BL-01 is a warm and mild V shaped, bassy set, it is smooth and non fatiguing, and it prioritizes timbre and tonality over technicalities. It is not an analytical or technical set for critical listening, but is a set very suited to just kicking back and chilling to enjoy the music. The BLON BL-01 does boast a good price to performance ratio for the price, but it needs amping to scale better, and sounds meh from a lower powered source.
Aerosmith might say “No More, No More!” to another BLON release, but the BLON BL-01 is definitely worth the cost of a small restaurant meal, and after hearing this set, BLON Cultists will surely say “More, More!! Take the Oppoty opportunity to Break the Levee to release mooooooar BLONs!”

ACCESSORIES
In addition to the IEM, it comes with:
1) Silicone tips of various sizes (one comes in a wider diameter, the other is narrower).
2) Stock cable.
3) Sackcloth pouch.
Essentially, the famous (or rather infamous) stock accessories of previous BLON iterations is here to greet us. This includes the barely serviceable cable and the usual BLON tips and lame sackcloth pouch. The meme generating BLON box advising BLON cultists to “LET MUSIC BURN”, together with BELIEF and NEVER GIVING UP and OPPOTY is however, not present!!!
Budget CHIFI companies need to cut costs somewhere, so as to pass down a cheaper price to the consumers, and accessories are understandably the first area they target. Some CHIFI (cough cough TRN BA8 and TRN VX) retailing at much more expensive prices may also have a similar dearth of accessories, so I won’t beat BLON with a stick for this and can close one eye, since this is a sub $20 USD set. Anyway, what’s more important is the IEM’s internals and how it sounds, and I think those of us in this CHIFI hobby might have some aftermarket tips and cables lying about, so no biggie swapping the BLON BL-01’s stock tips and cables out.
For the purposes of this review, I stuck with the stock tips and stock cable, so as to give a fair impression of what the average layman will encounter when opening the packaging (who may not know about tiprolling). Aftermarket tips (or cables if you are a cable believer) may skew the sound signature, and aftermarket eartips may not fit every individual ear anatomy, so it might be quite different in sound if reviewed with aftermarket accessories. Hence, I felt it would be a more fair apples to apples comparison to do the review with stock accessories, even though they ain’t optimal, at least we have a common baseline accessory set to discuss. But for sure I’d swap to aftermarket tips and cables for music appreciation for the BLON BL-01 once this review is over.
BUILD/COMFORT
The BLON BL-01 really looks like a mango or banana, in fact it is nicknamed the “BLONANA” on some audio forums. Looks aside, the BLON BL-01 is just slightly better in fit for me than the infamous fit of the older brother, the BLON BL-03 (ie that’s not saying much, they are both iffy in fit due to a too short nozzle). But as usual, when it comes to fit, it’s YMMV, as we have different ear anatomies. I managed to get a proper seal with the BLON BL-01 using the stock tips, but I would have preferred a longer nozzle eartip or spacer to use with the BLON BL-01 as it felt a tinge insecure for me with stock eartips.
The BLON BL-01 is made of a nice metal build, and comfort is very good. I have used it for hours with no issues. The shells are on the heavier side due to the metal, so some who are sensitive to weight may have issues with it.
I didn’t find any driver flex. I liked that the BLON BL-01 came with a 2 pin connector, as I had tons of issues with MMCX connectors and their general longevity in my CHIFI journey.
ISOLATION
With stock tips, the iolation on the BLON BL-01 is above average, better than the BLON BL-03 older brother. But like most dynamic driver types, it is vented and hence it doesn’t have as good isolation as some unvented multi BA types.
DRIVABILITY/SOURCE
I tried the BLON BL-01 with a Khadas Tone Board -> Fiio A3 amp, Khadas Tone Board -> Topping L30 amp, Shanling Q1 DAP, lower powered smartphones, Ziku HK-X9 DAP -> Fiio A3 amp, Sabre HIFI DAC (ESS ES9280C PRO) and Tempotec Sonata HD Pro. The BLON BL-01 is rather hard to drive from low powered sources. One only gets the full potential when amping it (due to the lowish sensitivity of 102dB/mW). It is not an issue of volume only, but the BLON BL-01 scales better in soundstage, details, dynamics and bass tightness with amping. I preferred brighter or at least neutralish sources with it in general, as the midbass was a bit bloated in the BLON BL-01, so it doesn’t pair the best with overly warm or bassy sources.
One might then ask a quite relevant question, does it make sense to pair a more expensive amp with the $20ish BLON BL-01 to unleash the full potential? Fair enough, I think most folks entering into this budget price bracket, or newcomers to the hobby may not be interested in getting an amp, compared to those that are entering the midfi market. As such, I probably won’t be recommending the BLON BL-01 to new users if you don’t have a more powerful source than the average non LGV smartphone. You can perhaps consider an alternative IEM if so, there are many other gems at this price bracket that don’t need amping. But for those that have been around the CHIFI block and are long term recalcitrant addicts to CHIFI, do whip out your amp or balanced gear if you have one lying about, so as to unlock the full potential of the BLON BL-01.
SOUND & TECHNICALITIES
In a nutshell, the BLON BL-01 is a warm mild V shaped, bassy set, which is smooth and non fatiguing, it prioritizes timbre and tonality over technicalities. The BLON BL-01 is not an analytical or technical set for critical listening, but is a set very suited to just kicking back and chilling to enjoy the music. Those wanting microdetails and technicalities best look elsewhere, but I would argue that it is much easier to find a technically proficient set at the sub $50 market, rather than something with good timbre/tonality such as the BLON BL-01.
With a good fit and eartip seal, the BLON BL-01’s bass is north of neutral, and is a level shy of true basshead quantities. It is slightly more midbass focused than subbass focused, but the subbass extends very well and can give a good rumble when amped. The bass is definitely faster and tighter than the BLON BL-03 older brother, but the midbass is still quite bloated and bleeds into the lower mids. Some might like or dislike the additional warmth this gives to the music, it’s gonna be a love it or hate it thing, so those that want a very fast and clean bass best look elsewhere. The bass is rather thick and is unfortunately not the most textured (though as said still an improvement over the BLON BL-03).
The BLON BL-01’s lower mids are recessed compared to upper mids. There’s a slight upper mids boost but this is quite tamed compared to most of the budget CHIFI out there. Female vocals are still more forward than male vocals, but not shouty. Some might find the mids a tinge too recessed for vocals and guitars, so mid and vocal lovers best consider an alternatively tuned IEM.
Treble is not that extended on the BLON BL-01, it is polite and safe, without sibilance/harshness. Though the other side of the coin of such a safe treble is that some microdetails and resolution in the treble is lost. I’m treble sensitive and this treble actually is my cup of tea, but maybe trebleheads and those wanting a bit more pizzaz in their music might find the treble too tame actually.
Timbre is good for acoustic instruments as per its single DD roots. Note weight is on the thicker side.
In the area of technicalities, the BLON BL-01 loses quite a lot of points for me. For example, instrument separation and details are not the best in the BLON BL-01, compared to other budget single DD types. There’s a fair amount of microdetails lost in the music, for pieces I’m familiar with. In terms of soundstage, height is above average, but width and depth is bang average. Imaging is good for the price, but music can sound congested and be smeared in very complex movements. Honestly, against other multi BA/hybrids at the same price bracket, the BLON BL-01 gets eaten for breakfast, lunch, dinner and supper in the technicalities department. Amping does help improve the technicalities, but overall, the music sounds a bit low res even when amped. But then again, this is nitpicking for a sub $20 USD IEM, and as we discussed, this set focuses on timbre and tonality over pure technical performance.
COMPARISONS
I chose some common budget single DD sets to compare below. I left out multi BA/hybrids from the comparison as the different transducers have their own pros and cons, so it would be an apples to oranges comparison as such.
VS the BLON BL-03:
For myself at least, the BLON BL-01 fits a tinge better with stock accessories than the BLON BL-03. I actually didn’t need to swap any stock cables or tips out to secure a fit, so that’s a plus point already. Isolation is also better on the BLON BL-01.
I am not sure about QC and unit variance, but my BLON BL-03 has more recessed mids than the BLON BL-01. The BLON BL-01 is a tinge cleaner and brighter than the BLON BL-03 in terms of tonality. BLON BL-03 is warmer and more organic sounding. In terms of technicalities, the BLON BL-01 is slightly better, in the areas of instrument separation, imaging, details, bass tightness, maybe soundstage, but both BLON siblings are better in timbre and tonality than technicalities.
If you ask different audiophiles on the forums, there will be multiple impressions for the BLON BL-03 when it comes to the bass department, since most folks are using different aftermarket tips with the BLON BL-03 due to the atrocious fit (too short nozzle). The different aftermarket eartips all influence seal and isolation and hence subbass amounts, to varying extents. Different eartips also change the sound signature of the entire frequency spectrum (which changes the perceived midbass amounts), so it is gonna be tough to compare the bass amounts on the BLON BL-03 among different individuals against the BLON BL-01 (not to mention QC may cause unit variation in bass amounts). Nevertheless, I did A/B testing with the same source/eartips/cables and when volume matched, the BLON BL-01 may actually be a tinge bassier (in quantity) than the BLON BL-03. But in terms of quality of bass, the BLON BL-01 is better. The BLON BL-01 has better subbass extension than the BLON BL-03. I find the BLON BL-01 is less bloaty in the bass and faster and tighter than the BLON BL-03 in the bass frequencies, with a faster bass decay in the BLON BL-01. Some may find that the midbass of both BLON siblings does bleed and encroach a bit into the lower mids, the BLON BL-03 being a much worse offender in this area. I’m a basshead so I don’t mind, but perhaps amping and aftermarket eartips may tighten the bass for these sets.
Overall, I would say when adequately powered and fitted optimally, the BLON BL-01 is a marginal upgrade over the BLON BL-03. The BLON BL-01 is also slightly cheaper, but of course that is in stock form (assuming aftermarket cables and tips are not added to the equation to achieve a fit among the BLON siblings).
VS the BLON BL-05S
Not to be confused with the shouty BLON BL-05 (non S), this set we are describing here is the radioactive green shelled one, the BLON BL-05S. For myself, the BLON BL-05S fits much better and is lighter than the BLON BL-01. The BLON BL-05S is less V shaped, and has a thinner note weight, with less bass quantities than the BLON BL-01. In terms of bass quality, the BLON BL-05S is tighter and not as bloaty as the BLON BL-01.
Both sets have good timbre as per their single DD roots, but the BLON BL-05S trumps the BL-01 in technicalities (imaging, instrument separation, clarity, details, soundstage, transient speed), and is easier to drive.
When both are amped, I would consider the BLON BL-05S to be a true upgrade over the BLON BL-01, though the BL-05S comes in quite a hideous shell colour, and of course the BL-05S is more expensive. But if you can top up the additional outlay, the BLON BL-05S would be my recommendation, if you don’t mind the gaudy shell colours.
VS the Moondrop SSR
The Moondrop SSR is tuned somewhat diffuse-field neutral with an upper mids boost, with a colder tonality and thinner note weight and poorer isolation than the V shaped BLON BL-01. It has less bass and is much more sibilant than the BLON BL-01. Moondrop SSR is shoutier at the upper mids/lower treble than the BLON BL-01, especially when used at louder volumes (Fletcher Munson Curve). For technicalities, the Moondrop SSR is much ahead of the BLON BL-01 in the areas of better clarity, imaging, details and instrument separation.
I’ve said this before, but the Moondrop SSR actually sounds nice at low volumes, but by pumping up the volume a few dB, the 3 kHz area is shouty and is too much for me (Fletcher Munson Curve). The Moondrop SSR has very polarizing reviews, and I think this may be due to the different volumes all of us are using it at, and volume levels are typically not mentioned by reviewers or consumers. Not to mention the different sources, tips, hearing health we all have may affect our perception of upper mids/treble in the Moondrop SSR. After doing A/B testing using the same source, tips (and even cable), I’ll take the BLON BL-01 any day over the Moondrop SSR, as the 3 kHz peak and the sibilance on the SSR is a deal breaker for me.
Different strokes for different folks though, I know a lot of our friends like the Moondrop SSR, especially those that use it at lower volumes. The Moondrop SSR actually has better technical performance than the BLON BL-01, but unfortunately it isn’t my cup of tea in terms of tonality, and I’ll take tonality over technical performance as my first priority. I haven’t had a chance to try the newer Moondrop SSP, which is supposed to be bassier but I’ll update this review if I get the Oppoty opportunity to try it.
Oh ya, how could I forgot the most important point of comparison here?! The Moondrop SSR comes with a waifu anime box! This box packaging may actually be the most important criteria for some purchasers and may make some shout at the moon (no pun intended)!
VS the HZSound Heart Mirror
The HZSound Heart Mirror is tuned neutralish bright with less midbass quantity and is less “fun sounding” than the BLON BL-01, especially when bass foward music is involved. The HZSound Heart Mirror sounds more analytical and colder, with a thinner note weight. Timbre, vocals and technicalities are much better on the HZSound Heart Mirror. The HZSound Heart Mirror wins in transient response speed. Both sets do need amping to scale to their best.
I see the mildly V shaped BLON BL-01 and the neutralish bright HZSound Heart Mirror as complimentary sets with different tunings to suit different music genres/preferences. But tonality aside, even though the HZSound Heart Mirror is more expensive, I think it is a true upgrade over the BLON BL-01 in most areas (accessories, timbre, technicalities, build, fit).
CONCLUSIONS
The BLON BL-01 is a warm and mild V shaped, bassy set, it is smooth and non fatiguing, and it prioritizes timbre and tonality over technicalities. It is not an analytical or technical set for critical listening, but is a set very suited to just kicking back and chilling to enjoy the music. The BLON BL-01 does boast a good price to performance ratio for the price, but it needs amping to scale better, and sounds meh from a lower powered source. I can see a lot of folks liking this set, considering it is rather affordable and has nice timbre and is not shouty or fatiguing. It is much easier to find a technically proficient set at the sub $50 range than something that has good timbre and tonality like the BLON BL-01.
So, this latest BLON hypetrain is being hyped to the moon and back and is being heralded as the next best thing since sliced bread and a giant killer. Does it deserve the hype? Well, I do think it is a very good budget set, but my honest assessment is that in terms of overall performance, it is probably a marginal upgrade over the BLON BL-03. IMHO, what holds the BLON BL-01 back from truly legendary status is that it hasn’t the best technicalities and the bass has bloat, this is more apparent when faster or complex passages of music kick in and things get congested and muddied. The BLON BL-01 also needs amping to truly shine (which a lot of folks entering into this budget segment may not have) and one may also need to swap the usual poor stock tips/cables for aftermarket accessories to secure a better fit, which can add to costs. Overall, these are nitpicks, considering it is a sub $20 USD set, and I still think it is a very good set, for sure it punches above its weight and has excellent value proposition, and is indeed a great addition to the BLON family.
Aerosmith might say “No More, No More!” to another BLON release, but the BLON BL-01 is definitely worth the cost of a small restaurant meal, and after hearing this set, BLON Cultists will surely say “More, More!! Take the Oppoty opportunity to Break the Levee to release mooooooar BLONs!”
Thanks for reading and Let Music Burn!!!
