Review on SVEN E-505B wireless headphones, black by Wiktor Lipski ᠌

I used different headphones - at least two dozen, I accumulated a big bag of different earbuds. These ears are not mine. You stick it in, you hold it with your fingers (you stick it), not much, the force is 10 grams, - everything is perfect ! You let go of your hands - EVERYTHING, no headphones, nothing is heard. Replacing the earplugs didn't help. Ears are good, maybe, but not mine.
