These were the third and probably last Samsung in-ears that I got myself. When the first that came with my phone, suffering from a loose connection IN minijack connector, I still thought: This can occur even once. As the second a few months later the same thing happened, I was taken aback. The last was a bargain because they were offered to me very günstg on Amazon when I ordered anyway just a few things. After a few weeks of the knob was broken with microphone, unpredictable sent commands to the phone, broke off pieces of music, simply put on ... not to use.
Add to this that I used earbuds other manufacturers to bridge and although the noise insulation is much worse outside, the sound was there much clearer. The Samsung in-ears are still pretty dull and swallow a lot of bass.
Conclusion: With expensive in-ears of more experienced party you're better off.
