Punches WAY above it's weight $$ wise
Exceptional detail, imaging and bass. Plain and simple I hear things with these that I do not hear from my ZSX10 Pro, TinT2, TinT3Pro and Tin P1 Planars. They are my daily...I keep trying the others and ALWAYS go back to the BLON 03. Want a negative? The cable it comes with is pretty much trash so I highly recommend replacing that. But to be honest, it's a small price to pay...

I am a big fan of cheap audio that sounds good. Who wouldn't be? I have a couple of sets of Tin T2s that I like, but they are a bit sterile for my tastes. Lately at work I've mostly been using some Koss KPH-30is, because once again cheap and good-sounding. I like the fact that they actually produce some bass but don't sound terrible when they do it. Got the BLONs....oh wow. These are quite possibly my favorite-sounding things. The bass is way better than I expected, and I was expecting it to be pretty good. Treble is still there, and never shrill with no sibiliance. Probably a bit more emphasis on the bass than people who want a flat response would like, but I enjoy it. Gives good depth to everything without being overwhelming (or sounding terrible). I haven't minded the cables as much as other people seem to. Sure you need two hands to put them in, but I can deal with that. I might try some foam tips a some point. Right now I'm using the largest of the silicone tips that they come with and getting a good seal and good sound, but they start to get a little bit uncomfortable after an hour or so. But every IEM does that for me, so don't judge them harshly by that measure. I can't recommend these highly enough.

THX789...sorry, typing on phone. I actually enjoy the bass more on these than T2 Pro, but it's marginal at best... I'm waiting for the T4 which I should receive any day now.

Blon 03 should have a lot of bass if you have tips with a seal.

You kidding? $30.00!
I have many iem's...Westone 80's being the most expensive. The world of iems is opening up thanks to China for that. These are very good and so worth the money. Buy them....you won't be sorry....Enjoy Try them with a portable amp and you will be living large!!

This IEM has already been reviewed and hyped up a lot.  I don’t have too much to add, but I REALLY like these IEMs.  The tuning is just so enjoyable.  They have a mild v shape, but the mids are not very recessed, and sound wonderful.  These are one of the few pairs of IEMs that I can easily enjoy w/o wanting to mess with EQ much.  My personal preference is a little boost at 500Hz and 1KHz, but it is by no means necessary.  The sound signature is actually a lot like my UE6s, which I also really enjoy.  They are not neutral, but are well balanced.  The bass is deep and very punchy. The mids are clear and really quite detailed for a budget single dynamic driver.  The highs are crisp and clear, with enough airiness.  No, these are not able to extract really fine details like good BAs or great DDs can, but they are not veiled at all either.   Fortunately for me, they fit well, with various tips, but I haven’t tried the stock tips (I don’t really like the shape and feel of them).  The stock tips from the TFZ No. 3 or S2 Pro fit perfectly, and sound good.  Foam tips also work well.  I have found that Final Audio Type E tips sound best to me, and also fit perfectly, such that they extend the nozzle a little. The stock cable also works fine for me, and is what I have ended up using, though the cable from the above TFZs also fit nearly perfectly, such that the 2 pin connection is actually partially covered.  I’ve already posted some pics showing this, in the photos section.   These are now my favorite $50 or less, single DD IEMs, surpassing the TFZ S2 Pros, IMHO.  The S2 Pros are a lot better regarding fit and quality of accessories though. The TFZ No. 3s are a little more resolving, and the bass is a bit faster and more precise, but the tuning is less enjoyable overall, to me. I’m really glad I purchased these on a whim, without having any real expectations, just curiosity. Update: After listening to the BL03s for a while now, I have a few more comments to add. There has been so much hype around these IEMs, along with controversy regarding whether they are majorly over-hyped. My analogy would be that they are like a really comfy recliner (sound wise, not necessarily fit wise). It is not ergonomic, not good for posture, and not technically a very proper chair, but you sit in it, and immediately are lost in the euphoric feeling, and just enjoy sitting in it for hours. The tuning of the BL03s are likewise that enjoyable. They are not very highly resolving, the bass is a little slow, with slight bloat, and they are not superb technically, but the sound is completely inoffensive, yet very fun and euphonic. You can just listen to your entire library of music for hours. No, they are not so-called “giant killers” per se, but one can easily enjoy these IEMs more than a ton of IEMs out there that cost 10-20 times as much, just because the tuning is THAT good. Update: My set was working great, w/o problems, then suddenly the left side stopped working correctly. Switched out cables, but alas, still not working properly. These can sound great. Current theory: I caused too much driver flex by fiddling with them a lot while wearing. Not too mad given their price, just disappointed. Latest update: I purchased another set, and the sound is just too good to pass up. They just have such a pleasing sound and tuning, intoxicating. Will sum it up with 4 stars. Highly recommended given the price, but buyer beware, and take precautions to avoid driver flex.

AxessDenydWith the Koss, get some Yaxi pads and an amp. The Mayflower Cmoy is a good one. It is essentially a more portable O2. It tightens up the bass and adds some upper end clarity to the Koss. It will help the earbuds, too.

JoeTheBassPlayerBeen thinking about some Yaxi pads. I do run an amp on my home computer (Fiio K3), though not usually with my Koss, which I tend to keep at work.

Just "OK" and Massively Over-Hyped!

They sound like Koss Porta Pro's... so if you like Porta Pro's and want an IEM... get these? They have the same level of detail, staging, and other properties... except with most tips they have less well controlled mid-bass... CP145 tips help with this, but once you hear it, it doesn't go away. These have been MASSIVELY over-hyped in my book, but still a decent set to consider compared to some others.

Still an Excellent Option in the Affordable IEM Market
There's been a lot shared about the BL-03s, and the truth of the matter is that they were and (to an extent) still are an excellent choice in the affordable IEM market. I've recommended them to at least a dozen people, and all have agreed that for the price there's little more they can ask for in well-performing, relatively comfortable, and user-upgradeable IEMs. This small but competitive corner of the market has changed in the last couple of years, and there are now a significant number of excellent products running for the throne in the go-to affordable IEM race. While you may find more accurate. more comfortable, or even more affordable options, it's hard to argue that one can go wrong with the BL-03s, especially when they're on sale. As a service to to the general populace, I've decided to share some snippets from the BL-03's manual, which is one of the most entertaining documents you'll ever own: BLON: BELIEF LETMUSICBURN OPPOTY NEVERGIVEUP USER MANUAL: Please do not use the earphone for watching videos or hearing emotional music when eating for health. In order to reduce the probability of being lost or forgotten for the earphone,please kindly fix the clip to cloth.When using the earphone outside and please kindly do not put in on those places which are easy to be neglected,such as desk and chairs. NOTICE/WARM TIPS it may affect your hearing,if the earphone is in high volumn. Please do not wear both the left and right sides of the earphone at the same time when talking to others for showing respect for others TURN The earphones are not like vases. Although the design reflects the thoughts and styles, it can't replace another indispensable element- the sound. The Chinese attach great importance to being adept with both the pen and the sword, and the Chinese works are no exception; the beautiful shape needs to coexist with excellent sound quality, which can make the headphones perform its value. "The soldier will be brave after feeling ashamed. If you want to achieve something, you must know your own shortcomings first, and then fight for it." "Although BLON has not achieved great success, it has made us see the results of years struggle and the efforts and changes required for the future, all of which derives from these years of hardship, accumulated experience, as well as the dream we have been hold on to"

I'm pissed. I'm pissed that I just now have heard these. Listen, and you'll want to, because maybe we should retire the term Chi-Fi. It's done. Over. Meaningless. Instead, let's give credit where it's due. The BLON BL-03 is stupid. You're stupider if you don't buy these for $30 or however less they cost. Buy 2 for yourself and 1 for everyone else you know. ~Rahsaan Roland Kirk's Jitterbug Waltz~ Search the keyword 'fun' and you'll see basically all 250 reviews because it really is the most curt way to describe these IEMs. Much like the HD650 (the only headphone I own; I sold the rest) I can listen to the BL-03 for hours. They rest lightly outside the ear with their stock tips that aren't half bad. But really they were designed with music in mind. They are very rich and full and rewarding if listening on a clean amp and dac. The other IEMs I own are the KZ ZS10 Pro and Ikko OH-10 but I know I'm going to reach for these often. Really often.

actsyalulzThis is pretty glorious review, are they really that good. which would lead me to ask, what other IEMs would you compare them too? In anything; soundstage, tonality, signature. Give me some kind of basis for your review, if you wouldn’t mind. I only gave these a quick look, but now I am quite intrigued. my final question would be what kind of music you typically listen too? While their can be crossovers the same earphones that are great for Rap, don’t always sound good for Rock. As I don’t doubt most here are aware of.

KramitThey don't sound like the other IEMs I own of which I mentioned previously. I can say that due to their single dynamic driver they sound a whole lot more natural for acoustic genres than if they had a hybrid configuration. I find balanced armatures often give acoustic instruments a tinny flavor. I listen to many genres and find these to be suitable for everything I have thrown at them. It really depends on the nature of the recordings themselves as you'll hear a lot of the nuances of production manipulation with these. Hope that helps.

Disappointed (in a good way)
I really had high hopes for this product. But everyone said the stem length could be a concern for some. Unfortunately, I ended up as one of them, even tried with foam and spin fit cp145 ear tips. I gave them to my mom and she was really happy about them. Especially because her ears are smaller. At the end of the day, I was disappointed I couldn't get a proper fit, but I am not going to take away a star for the stem length because that was expected, and spoiling my mom is never a bad thing.

Mainstream KILLER for the money
The stock eartips don’t fit me wel, because I have funny shaped ear canals. A benefit of the aftermarket Comply foam eartips is that the passive noise isolation is exeptional for traveling. Cable is the weakest point of this IEM. The bens causes a hit or mis type of scenario regarding the seal and fit. The Comply tips solved that for me! The sound is not that audiophile as alot of people say, but it’s not bose/beats crap either. It sits in between. I’ve got it hooked up to a Topping MX-3 with an build in DAC and headphoneamp, but that is absolutely not required. The low end is for sure it’s strong point. You can hear the quality rather than the quantity. Mids and highs are like a 7/10 while the bass is 9/10. You can really hear the quality of the recording rathar than a blob of sound. Its’s a warmish IEM, but not bass heavy. Yet again, for the price it’s an absolute steal. Easly beats everything mainstream under a $100. I got them for $ 22. If you like a more mid and top end focussed IEM, go for the Tin T2’s. But if you’re music style is more focussed on low end precense, get these gems and you’ll never look back for this price :) Cheers from the Netherlands

Poor Fit
Tried numerous tips and have yet to make them fit properly, I have to push both into my ear canals to get them to seat properly and get a good seal because the stems are too short. They need to provide more tip options or a way to extend/elongate the stem or a way to secure themselves to the concha of the ear. I have about 15 IEMs from $15 to $250 and never had a problem with proper fitting. I do have a large ear canal but between Comply's, tapered tips, Misodiko S450, or large SpinFits I can get a good fit. Not so with these. I literally have to actively push them in with my fingers to be able to evaluate the sound, and it's not bad, but since they will not stay in the ear, they are unusable.

AcousticoI cured this by purchasing some mechanical keyboard key O-rings. Sounds crazy but the little rubber O-rings that sit under the keys of mechanical keyboards fit the stem perfectly and add a tiny bit of distance between the tip and iem thus allowing the tip to go in further (albeit it 1-2mm)) but made a huge difference to me and the seal
