Bought these headphone for a trip to Europe. Very vague instructions. And the charging wire it comes with is worthless unless you’ve already bought an iPhone 11Apple charges a ridiculous premium for their products. When the package arrived, I had the suspicion the item had been repackaged. The shoe fits like a birkenstock should but the ""Birkibuc™ synthetic nubuck upper made from acrylic and polyamide felt fibers" is total garbage. However, I suggest you use your own big screw drive if you have it so you will not have a hurting hand next day like me. However, if you lay your head on a pillow instead of the bear mattress, everything will be fine! My family is old school and I have been wearing some kind of cincher or girdle since puberty so my definition of comfort might not be the same as another’s. I love these headphones they have everything you need for the price compared to other way more expensive headphones because of just the brand name. Great, sturdy protector.
