Bass Stereo In-Ear Earphone Wired Headphone Earbud Metal Headset for Phone PC

This is not a real jack with 3 levels, this one has 2 which means that I cannot use it with all phones or computers, it does not work like with the other headphones that you sent me and which are compliant, I have always been a customer of yours for a long time and satisfied with the products but this time no, what do you offer me because I cannot use the product

The sound is very bad, it is a very metallic sound without bass or treble that has a minimum of quality, or is it that, or is it that they are damaged because of something else that is not understood. It is worth that they are cheap, but at least a minimum of quality.

product below expectations. audio not at all clean and we can say "fuzzy", lacks clarity of the sound transmitted by the earphones. I was disappointed, it promised well

Joom is a total embarrassment, my son won 2 products for 10 money and did not receive them, later the 10 money was returned to him. Site by kko I DO NOT RECOMMEND JOOM!!!
