I MADE THIS THREAD WITH THE IDEA OF TEMPERS ASKING FOR OPINIONS/RECOMMENDATIONS BEFORE BUYING ITEMS FROM THE INTERNET.
So, they've arrived today. They have no brand.
Initial test showed me that they're either:
A: Inproperly soldered 3.5 jack.
At first, the sound was kind of empty, as if you were in a huge chamber hearing echo, I got totally disappointed, but then found that moving/holding the jack distorted the sound.
I managed to get them in a position where they stopped sounding bad.
My go-to sound test, is a song by Moloko.
It has great bass, panning and high tones throughout all the entire song so it's natural for me to test any kind of reproducer (headphones, earbuds, speakers) with this song;
I then heard that same song with Apple® earbuds.
I then played the initial bass part of that song repeatedly alternating with both earbuds, and they seemed to sound exactly (or near) the same.
Here's a size comparison.
Decided to test further with this video:
And surprisingly, the newly arrived earbuds hit 15k hertz and a complete bass limit test.
Still not sure if me not hearing beyond 15K hertz is because of the earbuds or my natural hearing.
I wouldn't buy these again, and I wouldn't recommend them to anyone else, but it's a good item and you literally get what you pay for ($13.00 MXN)
Still, I'm sticking with my custom made SONY headphones.
They've been with me for about 5 years now.
Maybe, these new earbuds could be used when I walk out Théo or when exercising.
