I really like these for use when doing other things while listening:
Far Ends short bud. I wear it while sleeping too. Player goes in shirt pocket, cord around back of neck to other ear.
Very durable. One ear is enough to listen for me, and I can hear ambient sounds while walking the dog or driving, etc. Fewer wires to get tangled.
They make longer ones, shorter ones, and ones with a volume control and mic.
