Best Buy

I'm new to the world of IEMs so i didn't wanna spend to much money but this BL03 is easily a Best Buy. I had some trouble with the fit in my ear since they kept falling out but after a short play with the included tips they are perfect. The sound is great, on the base side, mids are really nice and treble not harsh. Separation is also good, not the best but best for 25$
Overall very satisficed with the BL03 and the delivery was also really great.

Really great sound for the price

You just can’t complain about the sound with the price they’re being sold for. Side Note: 1)You can actually replace the wire and I’d recommend buying a better quality one than the one you’re given; it’s really flimsy and gets tangled too easily. 2)If you’re not used to having to jam the earbud nib into your ear to get amazing audio then it might get some getting used to. I used the Apple Earbuds for the longest time (the BLONs sound way better btw) and they sat in my ears pretty “lightly” at least compared to these. The BLONs aren’t necessarily uncomfortable, they just felt different.

The don't stay in my ear!!!!

They ended up in the bin as they do not stay in my ear!
When I hold them pushed in the ear that they sound really good.
The cable us garbage, the connector is garbage.

Still one of the best budget IEMs ever

I love the Blon BL-03's warm signature. It's a comfy yet still detailed and fun listen with good bass and outstanding tonality. It just feels really natural to listen to. The build quality is excellent, really love the purple color and the benefit of this particular model is that it comes with better eartips. This is my only concern: the nozzle is very short meaning it doesn't hurt and feel really comfy to wear but can be hard to fit as they might slip out of your ear. With the included eartip in the purple version it's fine but i highly recommend pairing this one with Spinfits like the CP100 or CP145. The cable is also a weak link in this package but it's decent enough and you can replace it or just stick with it. Very easy to drive but i also recommend a simple DAC dongle for your phone for a more open sound and a bit nicer bass.
Highly recommend anyone to get a pair of these.

Would give 0 stars now if I could. Just bought and already garbage.

Not only do they need to be pushed back into your hear constantly, but the earbuds disconnect from the wires during normal computer use almost every 3 minutes, needing to be pressed back into socket (they fall right out when dangling from the wires). Loud buzzing when tilting my head so they are unusable unless upright. Uncomfortable for long periods.



Great cheap IEMs for a first time user.

when it works its great but as some issues

i would rate this a 4 if it wasnt for the issue that the left earphone is noticably quieter than the right one for me, its pretty annoying.
