I am disappointed with the product, as it takes time to load to detect and start loading. No issues with sound quality, the pop filter works just fine. that being said, weve purchased several PediPed shoes in the past; these somewhat disappoint because theyre very stiff. Great deal for replacement parts. They are hard and uncomfortable. That said I am now used to them and it is a lot better now. (I guess the contractor thought we were gonna swim instead of doing jumping jacks! Les baskets font le job, mais elles ne sont pas dune extrême qualité. This is where youll also find the elusive ANC. I was impressed with this, because a lot of cheap headphones try to do ANC and it doesnt sound good.
