I?ve listened to music with these on for about two hours and I?m honestly amazed by how much the quality has increased. In other words, dubstep and similar might be lacking in effect, without the assistance of a wall/corner as well as being generally closer to the speaker. I have normal feet (not narrow or wide) but the top of the sandals is very tight and uncomfortable. Plenty of extra hooks for us and all the kids. I use this sandal primarily inside my house. It looks nice on my desk and it works great. I picked up the new version as it made sense to have an extra for my PC and leave the other hooked up to my xbox. the sleeping tips based on your patterns are actually insightful. I love this sandal, it fits perfectly, great for running errands, vacationing, you can dress it up or down. Functionality of the dock is great.
