I bought them a little more expensive because I got them from a random local store (around $8-10). They have very good and powerful sound for these prices and for this type of headphones, BUT they get tangled quite a bit (it doesn't bother me that much, but if they go in your pocket, you have to take them out and untangle them by force). My main issue is their button, not so much during calls but with music. Normally, with one press you pause, with two skips, and with three replays, but in these headphones it doesn't work well and you have to press pause again to start, you find it but for the other commands, you need luck to catch them. They are cheap headphones, but there are other similar ones that are cheap and the button is more accurate

For their price, they are fine.... They have a weaker sound compared to others I had, and I have to almost max out the volume, but they don't cause me any issues

Decent headphones especially for their price. The only downside is that when the volume is low, you can hear a bit of static noise, so I usually increase it a bit

While I can hear the speaker very well, the microphone never worked. I don't know if it was an issue with the specific piece I bought. In terms of appearance and material quality (except for the plastic of the microphone), it's fine. If it wasn't for this flaw, it would be value for money.
