Well, if the price is in consideration, then something like a used Element II(250$~) would be a great choice, as I know, Element III has options for you to switch between speakers and headphones by pressing the knob or button at the back of the device, the main killer feature is a BIG knob, it's so good, that after using this knob, you will not want to get back to other devices, I can recommend it definitely for build quality and user experience
