I listen to podcasts in one ear while working until the battery runs out, then switch to the other. I used the supplied Phat Tire kit for the one bike and then added my own Velcro straps cut at 36" each so they would wrap around twice and stick back on itself. I use the LDAC bluetooth codec to stream my own FLAC or WAV files or stream them from Qobuz. Good charger, heavier duty with a sturdy cable that allows fast charging. They look adorable with leggings! This is how the boots came OUT OF THE BOX. If youre looking for something sturdy to last a while I would find something else. Convenient to have something with you to hold your bike while you do a quick fix so you can get back on the trails. I can only conclude these lack proper air flow or something, I live in a semi-arid desert environment, its rarely humid, and its quite cold. My husband and resident handy-man put this up in about 5-10 minutes.
