He loved these shoes. extremely comfortable and responsive. Overall, Im very satisfied and will likely order a spare set in case these wear out. Im hoping they are as durable as other reviewers have stated. I?m buying more! 5 or 10, Im not sure those would have been much better. It was in a large plastic baggie like youd use in your kitchen (thats OK, but really??). It appears the 10 hour prediction is about rightWater usage. The overall basic first listen to the CF2W (CF2W for short, because I am tired as hell writing it out), is warm, and has a bass tilt as well, very reminiscent of their house sound. Several individual benchmarks showed greater than 10% improvement.
