Over time, I have five different spare Samsung In-Ear (for the whole family) obtained from low-cost sources. Optically identical, the quality falls but from very different. 2x excellent, 2x lower midfield, 1x straight so useful sound. Well, they were all usable, and the noname for this low price sounded really an underground operation. I will probably order again when needed and hope then again to get lucky, because for the price I do not know any alternative.
