But they also have disadvantages:
Cable noise (far more than normal in-ears)
Fit very important (once the headphones even a millimeter seated incorrectly, the bass go west and everything sounds schepprig)
The rubber earbuds do not buy more, incidentally. Plugs from other manufacturers fall off. Only through the online support I received the message that one can order the rubber plug at all. In another request me a price of 25.00 was called, I consider to be usury. These are 70% of the current purchase price.
