Thank you very much! They need some time to break in so be patient. This flexibility leads to tearing the fabric cover loose from the base and then the whole thing starts to fall apart. The armband for the phone that came with is also very useful when running. I supporti all’interno sono in gomma, ottimo per non graffiare le lenti ad esempio. (Not like a hair piece. I really like these in a visual sense. I will never purchase anything delivered like this again. I should have not listen, because they are too small! They exchanged it for me and Im a happy camper now.
