The FSL monitors come with a range of accessories, which ensures that they are likely to be adapted perfectly to every ear. So are 5 versciedene silicone ear pads, 3 pairs of different-sized ear-fins that provide the ear for maintenance, and a pair of ear-hanger, which also the cable is routed behind the ear. They can therefore not only in everyday life perfectly in the ear, but also in sports activities. I have them tested by mountain bike in the field, and even where it was really bumpy, they have kept perfectly. Another practical feature is the sleeve for holding, which is conveniently closed by a zipper, and which ensures that the cable in your pocket, for example, is hooked to the keyring.
Overall, I would not hesitate to give it 5 stars for the FSL Zinc Zn30i because in addition to good sound quality and processing the accessories really convinced.
