Never had suede Birkies before but they are super soft and comfortable. The battery will get you through about 1/2 - 3/4 day if you use for both calls and to stream audio, about 3-3. It?s not often that my expectations are met much less exceeded. Overall they have some flaws, but they are the best option if you want Bluetooth headphones that being slip out or trigger touch controls during more intense workouts. Viene un poco más pequeño de la talla, pero están muy padres The photos look like the bike is on the ground but it isn?t. Now the BASS! My all time favorite headset was a Koss Pro4AA, which I bought in about 1972. All the buttons are as responsive as a factory controller from Sony. It doesnt feel much different from walking in my flat boots to me, it just has more structure to the footbed because of the heel and curvature around the side of the arch.
