Headphone hookups for HD24-500
I currently use over-the-ear Sennheiser RF headphones with my HR24-500. I'd like to use something other than those, which work well but are bulky. What do I need to know to replace them with another brand or type; can be Bluetooth, WiFi or RF. What kind of connections are available on the HR24-500? What would I need to do to hookup Bluetooth or WiFi?
