Does the Joey 3 have built in Bluetooth for headphones like the Joey 4K or do you need to add the USB Bluetooth adapter like the Joey 2?
You need the adapter
The two tuners in the SuperJoey are for use in the Hopper only, there is no connection to the Joey portion of the receiver.Even the SJ that has 2 built in doesn’t. Probably could but doesn’t. If they were more popular before the H3 came out dish might have added it but they seem to be pretty uncommon.
No, they are completely different. 4K Joey is the only Joey model capable of 4K, and even it does not do it very well. (No HDR support)Joey 3/ Joey 3.0 is the same as 4K Joey
Sadly. Hopper 2000's and Hopper/Slings still come with Joey 1's on new connects and upgrades, making Joey 2's basically useless now..... smhAlso, Joey 3.0 is the standard Joey that you will get included now with any new Dish installation or receiver upgrade. Dish charges you an extra one-time fee for an upgrade to a 4K Joey.
