I havent saved any profiles, so this appears to be stock performance. I was surprised that Amazon sold them for $15 more than the Clark website. What I do notice is the soft HISSING when you turn them on. Super happy with this new little toy. I fits perfectly on my pantry door, and is serving the purpose I bought it for. Waste of money! These shoes are simply fabulous. The bikes do stick out into the garage, but that’s no surprise. I hate the way my hair feels and looks after using shampoo (fluffy, frizzy, dry) and always have to use more products to manage it. I’ve been using IEMs for 10 years playing live music.
