The Marshall Minor FX (bought twice in black and white) does not seem to have all the previously experienced shortcomings of other products. The earphones deliver good sound and a perfect fit, do not fall out of the ear. The "speaker" is protected from sweat. The listener is clamped between the upper flap of skin in the ear and ear edge. There are different sizes Klemmer.
There is one aspect, which I would describe as "lack": The cables are fabric-coated. This may be a sign of quality workmanship. But since I primarily use the earphones for sports applications, it is more practical because the cables are wet with sweat and not be easy to clean.
The shape of the ear clip the cord tangled during storage easily with Höhrer and switch. Here one could easily remedy this by a special storage box. (You can help yourself by pushing the Krokodiklemme to plug and thus the earphone clamps).
