Product Description
Nothing compares to the sound of a true speaker system, but BLON’s BL-30 headphones come pretty close. That’s because they’re equipped with huge 70-millimeter drivers and an open-back metal mesh cavity—two key components that replicate the performance and sonic characteristics of a true loudspeaker Read More

Uncomfortable. Ugly. Poor fitting.
This is day zero impressions. Zero burn in.
My signal path at time of testing is Roon -> Ropieee on Rpi4 -> Airist R-2R -> Yaqin SD-CD2 buffer with WE403B tubes -> ZDR Jr. with Voskhod 6Ж1П-ЕВ input and Zaerix ECC89 power (probably Tesla manufactured, definitely not Russian or Brit) using the high Ω socket. I'm using the stock cable as the amp I'm testing with is single ended.
These are uncomfortae at best, painful at worst. They press in a very not cool spot on my skull. The headband padding is a joke, and I'm not sure Dekoni nuggets can fix that. The earpads are complete garbage ugly fuzzy abominations. I get just barely enough seal against the sides of my head when extending the headband to the maximum size.
Sound wise? Surprisingly not horrible for the price. Not accurate, not tuned towards any of the worthy targets, but fairly pleasant. Very fat bottom with nice sub-bass. Mids and treble feel a bit recessed. Female vocalists and classical these are not made for. EDM and classic rock though? Almost worth the cost if they weren't so bloody uncomfortable. They are playing rather nice with pure tube amp, which is good.
I'll definitely have to leave these playing Opeth Blackwater Park on repeat while I sleep. Seems to work all the tightness out of all the cans and IEMs that have gotten the treatment.
My initial feel on these is that you should buy something else unless you plan on doing heavy modifications. The HE-35x for example is cheaper, more comfortable, and sounds better out of the box.
Same day edit:
Switched to using my xDuoo TA-03s (with JJ ECC802s for voltage/gain and 6С19П-BP for drivers) for a bit of OTL amplification. Tightened up the bass, but it is still pretty excessive. Treble is still somewhat recessed, at least compared to how overpowering the bass is. I also stopped trying to serious listen and did the TV and Movie thing. These cans actually sound pretty great for action movies and the likes. If their target sound was cheap full range speaker from the 70s, they definitely nailed it.
They are still incredibly uncomfortable. They need 3-4x the padding they ship with, and the headband needs to be about an inch longer and bent with a sharper angle inwards inwards to allow the cups in yokes further freedom to conform to big heads. I absolutely hate the feel of the hair magnet earpads and have already ordered a set of Brainwavz sheepskin that should fit. My causal inspection has shown this set does NOT have the earpads glued in place.
I've also learned that they will happily eat long hair when being taken off, and painfully so. My Meze 99s eat hair via compression, these eat it via sharp upwardly bent metal star style lock washers holding the post to the yoke. I'm not sure which I hate more, but these are definitely learning towards being the winner of rage. Not cool that, but totally in line with the absolute shit level of fit and finish.
Same day edit 2:
Forgot to mention the cable and case. Out of all the crap and rage I throw at these cans, the most basic accessories they come with are surprising in the price bracket.
The cable is ultra basic 3.5mm TRS to 3.5mm TRS*2. The connectors are the standard high quality generic chinese stuff you see all over the place, not bad, not amazing, but easily repaired. The wire feels like 26gauge and just a simple pair of conductors per channel. I'll have to hit it up with my multimeter to get resistance and capacitance reading and map out the wiring some time. They used a very simple twist braid which leaves the cable supple and the nylon wrap they used is smooth feeling against the skin. Most importantly it is NOT microphonic. No noise is heard in the cans when running ones nails down the cable or smacking it against surfaces. Cheap, but surprisingly better than a lot of stock cables. My only complaint is the length, it could easily take another metre, but if you're sitting within metre of your amp, it is more than enough.
The case is a generic nylon cloth covered plastic thing with a double zipper. It fits the cans fairly well, but leaves a bunch of empty space for them to rattle around a bit. Totally not horrible, but like everything past the drivers/earcups/cable it feels like an afterthought. I'm not complaining about it at all as it'd be easily modified to provide better protection with some glue, foam, and felt cloth.
Same day edit 3:
These things make metal on metal noise when I move my jaw. Like noshing on pizza and all I hear is clink clink clink of the yoke hitting the metal cup. Am going to have to slap a small bit of kapton in there.
Last Edit; Day 2:
Reducing score from two stars to one. One of the yokes fell off the stupid post, dropping the earcup to the ground. The bloody screw came undone. Instead of using lock-tite, they used a shitty star style lock-washer of the wrong size. So, while I was trying to figure out why the cans had so much distortion when moved a bit that happened... then I saw why these things distort so much. Pull the pads off and lightly blow (and I do mean light), you'll see the bloody driver flap about like a jellyfish in a wave-pool. I checked the other side to be sure it wasn't a fluke, and it was consistent. Plus it turns out at least one of the screws holding one of the driver assembly in place to the ear-cup was just press-fit, barely holding in place. The screw hole was drilled wrong so the threads didn't bite.
These go straight into the garbage pile. The first and very much so last BLON product I'll be wasting my money on.
TL; DR:
Do yourself a favour and buy something else. These cans are shit. Their design is shit. Their construction is shit. Their components are shit. They're heavy and uncomfortable, requiring more than they cost in modification parts to be viable, and even then they'll be shit. They sound like the absolute trashiest and cheapest of the cheap full range range speakers you could buy from Rat Shack in the 70s and 80s (you know, the ones your idiot friends inadvertently purchased while thinking biggest driver bestest driver).
Bugger that noise.

We are suckers...
Completely useless garbage.
Crossing my fingers Drop makes it right.
*Edit- drop did NOT make it right, first associate said it was out of the 30 day window (had been like 5) and closed the claim. The second associate basically told me they are not actually broken just poorly designed, so they dont qualify as a warranty return.
Talk about CYA. I'm going to be taking a vacation from Drop products and from Drop peddling reviewers for awhile. Should have learned my lesson with the $30 DOA brass flashlight they wouldn't replace either. Do yourself a favor and buy elsewhere if you can, Drop does not support their products.

DrGonzo4311The blon overlords must have decided to burn the "brand" to flip some junk they've had laying around. Pandemic probably left them in a tight spot with merchandise inventory and production capacity.

Oh dear god...
These are one of the worst headphones I've ever heard. The build quality is OK, but the design is poor and then the sound tuning is pretty horrible - thick, muddy and lacking in clarity (and I like warm, bassy headphones!)

utter garbage
So i already knew these cans were trash but i decided to get them for some modding just for the fun. Well what do you know they are even bad for that. I tried to disassemble them but in blons genius they decided to glue the screw-nuts inside the cups and that glue just didnt stick so i had to drill out 4 of the total 6 screws. Guess i'll just reassemble this shiz with the power of glue, cant be worse then before

JohnAconHahahaha, I found these at the bottom of a box of my cans to be trashed and after reading this review I couldn’t agree more. There is no amount of modding, EQing or amping to fix how terrible these are lol. The fit is awful, they hurt and don’t even seal around your ears, they kinda float from the top of your ear and stay open at the bottom. Forget new pads too. Junk. Take the drivers out and use them as speaker phone speakers.

Hey at least they look cool...
Loud, low end, no detail. They look cool and start conversations but that's where the fun ends.

Their OK at best.
Decent build, comfort could be tiny bit better, Sound not stunning but also not bad. We will see when they finish a hundred hrs. burn in. Possibly worth the money but not more.!! UPDATE... I do not know how to describe these horrible abominations, dumpster fire? train wreck?.. well pain will only make you stronger.

These sound good, but dont feel great.
While the sound quality is pretty good with the right amp. The fit of the build leaves some desire for improvement. Honestly 100$ is a little much for what it delivers, but you can find better headphones for the same price. If these were not so flimsy and fit better then I would give it a bigger score.

Disappointed!
As always the bass is there. But as I feared, the top end was very sparse represented. On another note, the metal chassis is definitely a BAD idea. So max 3 stars from me. The 3 stars is listening to movies I would actually only give the music performance 2 stars. They are definitely not linear. Seems to be a very unfortunate trend. Producers of gear has to go back striving for linearity, instead of bass,bass,bass....... I FCKNG HATE IT. Make gear NATURAL again!!
