(I see there was some confusion about that for some. The round metal piece hurt my foot for about the first 10 wears. Currently the PX7 retail for $399 USD which puts these firmly into the high-end wireless headphone category. Now I only wish more accessories allowed you to use your own suction cup hooks! That being said, it was really painful at first but even after the first try your legs get use to it. The bass is definitely not overkill though, it just adds a bit of oomph to my music. These would fit a 3-5 year old child just right. For me this is a great set of headphones for the cost. as of june 17, 2020, i hope that adidas will continue to make the adilettes, it is an amazing slide. In the end, I would say buy only if you want to experience ANC or want an earbud design earphone.
