I'd share a bit of my opinions on budget earbuds acquired recently, so people can get more info about them.
Sen*** Kp580: Don't understand why some people call them bassy. Their bass maybe sufficient with good seal, but overall upper-mids dominant. Clean sound, and very easy to drive. Excellent built! Would've hope more layered sound by them, as I couldn't enjoyed them without Bass-elevated EQs.
It's unit variance for this set. Some owners don't have that upper-mid elevation, even calling them warm. I, personally, have one that has grainy/rough upper-mids and elevated bass so I decided to do some reversible mods (also driver flex). You're not getting any driver flex?
There's a version 2 without the MMCX screw just so you know.

When I opened mine up to fix the phase wiring, there’s a significant amount of glue inside, both around the driver and also around the mmcx. Some of that glue could invariably drip down and block some or all the front vent before it’s had a chance to cure.
That’s apparently what happened to my first set that had the terrible driver flex. The glue had covered up the front vents.
The front vents are what impacts bass, which is why my first pair sound different than my second pair.
It’s not a big deal though; this issue can theoretically affect any earphone, and was easy enough to fix.

I wouldn't be surprised these CHIFI companies do OEMs for each other. Just with a different logo on the shell.
Or they source drivers/shells and stuff from the same factories.
You don’t have to open them up to correct or address the front vent, but you do have to open them up to resolder the wires to correct phase.
As far as the front vent, you need cobalt steel precision micro drill bits (which are a specialty item, not something you buy at the local hardware store). You then make a new hole in the nozzle using a pin vice. You have to prevent metal shavings from going down into the nozzle, and you also can’t make the hole too big, or you will screw up the tuning. You also have to make sure you don’t break the drill bit, which is very easy to do as the correct size bit is literally as thick as a human hair, and will snap off in the nozzle if you breathe wrong. Then you’re screwed.
If you’ve never done it, I honestly wouldn’t recommend it because so much can go wrong. I’ve been building IEMs for years, and working on fine jewelry using the same type of drill bits for over 30 years. So it’s literally a walk in the park for me.

Honestly, if there’s something wrong with your pair I would just let the seller know and I’m sure they would send you a new pair. That’s going to be infinitely easier than trying to fix them yourself. I mean, the cost of the precision drill bits alone exceeds the cost of a new pair @$12.
I only fix that sorta stuff myself because 1.) I already have all the tools, 2.) I have the experience, and 3.) I like the challenge of fixing stuff.

I do like the white color of the EDX with the copper cable and will probably buy them eventually based on that. And, be disappointed? Except for the physical presentation.
PS: What do you like about them and how often are they used?
