Once they are broken in though, wow they last and seem to keep my feet from aching. Though the instructions had graphics too small and there were some poorly drilled holes that made it somewhat difficult to get all the bolts in. Im wondering if they are fitting more the standard for the host nation than the feet we have in the US. Our main brands are Plae, Keen, and Merrell. Good sound quality and battery life too. 5W in dress shoes so I ordered the 7. they are very nice for your sundresses and jeans. ? Una muy buena batería, dando unas 25 horas de duración con el ANC activado. They fit very well and are very comfortable. I will go ahead and give Bludio 2TS a try because I really love the sound quality.
