Shoes: Keen you cant go wrong. Received damaged but didn?t want to go through the hassle to return it. Many laughs watching adults flop up on deck like a fish & having to rest from the workout. It does not use the headset, but all audio in/out was using my phone instead. While this speaker is also a Klipsch, though the 10", it is their newer design and while I could not determine if they made changes in the crossover or the woofer itself, we took a shot and bought one. Its not even a cost issue its a lack of thought and planning issue which does not fill me with confidence as to the quality and lifespan of the product. Some heels fell off but they included extras and glue to reattach them. Do not by from this company. Shipped next day! These shoes are great!
