Edited to expound my comment
From your options the Salnotes Zeros are the only ones I've used, but from my experience they've been incredible.
They're consistent and the cable is easily replacable. I've been using them as in-ears for my local church music team and they're great. No brainer at that price to be honest.
I also use them whenever I have to mix something while in a noisy environment.
To my ears they're neutral with a biiiit of high mid emphasis. The bass isn't prominent (which I like). I use mine with foam tips because silicone tips don't work well with me for any IEM.
They come with several tips out of the box too.
Highly recommended
The truthear zero is great, but the salnotes zero does almost 90% of that for a lot less.
what do you think about these? i heard they are new and highly rated
I personally have not tried them but they're an overall improvement, and pretty good value. Watch some reviews of them on YouTube, should give you some context
I dont know the ones you linked, but I bought these a couple of months back and am very satisfied:
Linsoul KZ ZSN Pro Dual Driver
I do own sennheiser hd25 and beyerdynamic 770 for reference and have had many 30-70 euro in ears over the years.
At 21 euro they are absolutely amazing.
The premium recommendation is: get yourself custom made ear protection, where you can different filters and buds in. Nothing fits better than something special made for you.
I cannot speak to these options. I have Shure earbuds, but also don't want to just recommend them as there are so many options out there today. What are your primary needs for earbuds, are you looking for sound quality, sound isolation? Are you limited to Amazon purchases? You may want to go down a rabbit hole on the Perrivan audio review site, https://perrivanaudio.com/oreo-list/. Good Hunting!
mostly i am concerned about sound quality
