El producto no es malo de hecho cumple su función aumenta el volumen en los audífonos y ecualiza razonablemente desafortunadamente el conector auxiliar viene con defecto y al emitir sonido lo hace de un solo auricular y tienes que mover el plug de 3.5 para que suene ambos auriculares pero tiene remedio reemplazando dicha entrada que no es cara y sin problema

I was hopeful, but this equalizer is like many other inexpensive equalizers: The 2 knobs controlling the upper frequencies introduce a lot of hissing. So people who like to hear high clear symbols and guitar will find there becomes more hissing noise than clarity. And if the yellow Volume knob is turned past about 11 AM on a clock face, then the unit is also attempting to do amplification, and you get both hissing and irregular popping sounds. I think it might work for people who want to make minor changes to the mid frequencies, and moderately strong changes to the lowest frequencies.

Le produit émet un bruit de fond très désagréable

Be nice if it came with the wall plug instead of a USB. Works good with a proper cord though.
