Ive been using these headphones for everything since about Jan of 2015.
Sony Walkman NWZW273S 4GB
They are very tight to the head and hold right below the goggle strap while swimming, and don't move around at all while doing lifts or sprints. No cord to worry about. Held up well to swimming (fresh water only!), sweat (used them in Guam), and wearing in the shower. I use them about everyday and recharge them so not sure how long the battery lasts without charging. I click and drag files from iTunes, haven't tried an audiobook but now that you mention it Ill look into it.
