Nice little speaker. This is super cute but it is bulky and seems to be a bit heavy. I wear Vibrams all the time, however, they are hard for driving a stick shift. these were *extremely* light. The roads were fine all except for the one police forced us to go down by baracading our only entrance to our street. This pair is a faux leather feel which the other is a patent leather. Im sure Ill use some more than others but eventually will get through them all. :)Use Update: Waiting for the skewer to come in so I can test it out. I have owned 3 pairs of these since my original purchase. On-board memory cannot be used because the software comes with it cannot write a profile to that memory.
