The concept of using dongles while walking around seems like it wouldn't be without inconvenience. What is your setup like and does it disconnect sometimes while walking?
I ended up having to buy Bluetooth headphones just to listen to music on my iPhone which has its own problems because they have to be charged all the time.
I am currently looking around for a standalone digital player, no market, no apps, no fancy anything, with a wired headphone (currently looking at KZ EDX Pros, despite the crinacle drama). Might end up getting another sandisk and doing a mod on it to hold 1TB. Those things are damn near bullet proof but their secret weakness is my washing machine
