Correr es impensable, el mismo peso del mando y contrapeso de lado derecho hace que los auriculares se salgan del oido por el movimiento. Read some reviews bad and good. Battery life is ridiculously long, I went to bed with them on, in the morning they were still going. theres a sound cone, and if you talk to the side of it, obviously no ones going to hear you. There doesnt seem to be any loss of sound quality over the original. Not happy with the quality. Install drywall sinkers (if necessary) then just screw the holder in place and your done. Im happy! Now, there are definitely flip flops with more comfort and support out there, and I have owned them too, but I’m not comparing these Nikes to that category of flip flops. Pockets big enough for all my size 6 sandals although they would struggle to fit my other half’s size 10s and won’t work for my heels.
