Review edit a few days later:After a couple uses, the charging base for the earbuds stopped holding a charge. They are angled back so the weight will roll back/down to the frame which is awkward for bench press. Not an everyday shoe but we use them a lot in California. Allerdings sind sie leider nicht so haltbar. Im also comparing them because the Er2xr is what I will still use for sleeping, besides these, as these foam earplugs cant quite completely replace them. I think if you take a 7 or higher shoe size, these might be too small for you. The quality for the little speaker is great. These are super cute and lightweight but still provide the support of a Chaco footbed! Soddisfatta! the only issue i have, is with the packaging.
