Amazing and very good quality for the price

I purchased these earbuds after hearing such good things and considering how many cheap pairs I've gone through, I thought it would be good to invest in something a little more durable. Quality is amazing, love the metal finish, and the design is funky but really helps noise cancel and keep the earbuds from falling out l. Also love that they included a little bag for storage. Only con are the wires. A little too long and thing for my tastes, but you can switch them out so, not really a con. All in all a good purchase and I'll definitely purchase another once these run their lifespan.

Right ear died, wanted me to pay for repair.

Right ear died shortly after buying, they wanted me to pay for shipping To and from China, and to cover repair costs... Audio quality was good while it lasted(a couple weeks). Wouldn't recommend.

BLON BL-03 Budget Heaven

It's very rare to find a no-brainer in the audio-world. Congratulations, you've found it. This piece of magic punches way above its price point.
I've been using it for the past two months with the stock cable and the stock tips. While they're not the most comfortable, and I am looking to replace them, they are fine for the time being.
Buy this for yourself. And for a friend. Buy 4 or 6 and distribute happiness. For kids, adults, and everyone. This is where it's at.
Thank you, chi-fi. I'll be coming back soon.

Not bad

Amazing value

They are some of the most enjoyable headphones/IEMs that I own. I constantly reach for them versus other more expensive offerings and also feel horrible about it at the same time. Buy them if you want to feel guilty about listening to them over anything 4-5 times the price because they are that good. Listening with final-e tips, stock cable, and a Qudelix 5k with a oratory’s parametric EQ settings.

Sounds Great With Some Fit Issues

The BLON BL-03 sounds very good but I had some challenges with fit. The supplied ear tips would not provide a good seal (so no Bass) and the supplied cable had a tendency to pull them out of my ears all the time. A number of reviewers of this set have mentioned this issue so I was aware that it might be an issue. If you aren't prepared for the hassle to spend a bit more on eartips and cables, this IEM might not be for you.

With some better foam eartips I fixed the seal issue and a Triptowin C8 cable (cost more than the IEM's but worth it IMO) fixed the issue of them puling out (also the foam tips help with this too).

I now have a good sounding set that I really like. Even with the upgrades to the cable and eartips, it's an excellent value. My old Shure 215's came with a nice cable and multiple eartips and cost a lot more. They sound like crap in comparison. Can't believe that I thought they were pretty good. LOL!

Cheap plastic earphones. Do not buy these

The earphones feel very cheap and plastic. The sound quality is not that good as people say. I would not recommend buying these
