Great sound for value

Let's start with the packaging first. In my opinion, packaging must be kept to a minimum. Less packaging means less product product cost, less shipping costs and environmental protection. The packaging must ensure that the product arrives intact. Nothing more. The packaging of the BLON BL-03 is essential but could also be reduced in size.
The cable as many have written is cheap and thin, but of course, what do you expect for $ 20? However, I like it and I just hope it lasts as long as possible. The pavilions are made of metal. I imagined them lighter but that's okay so they give a nice sense of texture. The headphones fit perfectly in my ears. Much better than the Tin T3 which I have been using for 2 years anyway and which I love.
The sound: first of all I prefer to use them with the foam tips taken from my T3. These tips have an astonishing quality and durability compared to the tips bought elsewhere. The sound of the BL-03 is very natural and using the foam tips you gain a bit more bass.
The soundstage is wide, more than expected. But, please, don't forget that the soundstage depends very much indeed above all on the recording.
The last tip I want to give is to look for great recordings. Not all recordings are the same and in fact today most things are recorded without care. Listening to a great recording is as important as having a great headphone and much more important than buying the latest DAC reviewed by the influencer on youtube.



Blon BL-03

This IEM is worth the hype.
With it's extended bass tone it will satisfy those who want a bit more punch in their music without taking too much away from the mid range vocals.
The higher frequencies are handled with care which makes for a warmer tone overall.
Sound is up close and personal with just enough space to give the instruments room to breathe.
If you're thinking of taking the plunge and trying IEM's for the first time, go no further.
The Blon BL-03 are definitely a 5 star IEM



Great all-rounder iem

These sound great for the price. I can imagine the comfort might not be for everyone but for my ears these feel like they were made for them. I have slept through many nights with these in my ears and felt nothing. I have never had any problems with the default cable. They feel very solid and I have dropped them quite hard a few times and still going strong after about a year of use. (I dont want to get into too much detail about the sound signature because im quite inexperienced with iems but for me they sound very basicly good) :D

Great Audio quality but issue with cord...

Hello there,

I only have been using these headphones for a few weeks now and the headphone cable has already gone out I'm unsure of how it has happened but I use these sparingly and was surprised when I plugged them in and found that the side of the cord that has the mic attached was not working. I have marked the review as a 5 star in good faith, and also due to the phenomenal sound quality these headphones produce. Potentially a replacement cable could be expedited to me. Please feel free to email me about this issue.



Who can imagine that such an affordable
pair of IEM can deliver such an incredible sound ?
No one before testing the BLON-BL03.
No one, really


I purchased this one to have an allrounded, well when I got them I realize the firm of sound an amount of bass was not something I was use to, I was not liking it at first but after doing the mesh mod and give it time to burn, I al now enjoying it, every single track sound great, with a lot of detail and a great amount of bass to bring the most fun out of every track, still can't believe something this cheap could sound this good


This is a great headphone, regardless of price. Really detailed and full sound, though I definitely recommend a thicker cable and I still haven't found the ear tips that are most comfortable to me, but there's nothing wrong with the ones that came with it for me.
