I wanted to share a cheap sound upgrade for the Blon BL-03.
The stock nozzle mesh is a hybrid ‘sandwich’ of stainless steel mesh stacked on top of a black nylon fabric mesh. If you remove the stock piece and replace it with a normal 4.0mm stainless nozzle mesh, the sound improves.
The first thing you notice after replacing the mesh is how smooth the stock sound was, and was slightly veiled. Replacing the mesh increases the clarity and makes the sound less smeared. Bass becomes clearer and more crisp. Lower treble becomes much less recessed and more balanced in the overall mix. Vocals are improved, and are brought more forward.
I’m not saying the stock Blon sounds bad; quite the contrary. I quite enjoy the stock Blon. But this turns up the clarity a few notches and everything is cleaner sounding, like the difference between cassette vs CD/flac.
You can save the stock mesh on a piece of waxed baking paper or even an unused and clean wax candle. In this way, the mod is totally reversible.
The 4.0mm mesh can be found on Aliexpress by searching for the term “earphone dust network”, and runs about $1 for 20pcs (ie 10 pairs). That’s $0.10 to upgrade a set of Blons.
This upgrade is nothing new, and many modders use this same cheap upgrade on other earphones that come stock with nylon mesh or stainless/nylon sandwich nozzle screens. I just didn’t realize that the Blons use a hybrid stainless/nylon sandwich nozzle screen. Otherwise, I would have tried the mod a long time ago. In fact, if I had tried this mod earlier, I probably would not have bought the Urbanfun ISS014. I actually think that the modded Blon sounds slightly better than the ISS014.
Anyways, enjoy and let me know how you like it if you choose to do this cheap and simple mod.
