As mentioned in other reviews, the shape of the headphones is useless to get used to and for me. Even with normal movements such as simple walking the bud immediately slide back out of the ear. One does not have different rubber-coated as with other headphones, but the fat, slippery plastic construct one pushes directly into the ear. Sound is okay, compared to ordinary headphones or in-ears in the same price class but rather weak. The headphones also isolate background noise only very meager. MicroSound is fine.
No purchase recommendation, and in the price range there are much better alternatives, the "Premium" are not, but to use it better.
