it IS the same one, like I said, there is no magic going on. The person who said the dongle sounded incredible with the htc 11 was either heavily biased to give a favorable impression or just easily pleased as I said, if your headphones sound good to begin with, chances are, with any decent source, the headphones will unironically sound good. There is no magically higher quality dac in the htc 11 bundled version when they are identical, in fact like I said earlier, it is likely just a passive adapter using the usb c over analog spec (the actual source would be the snapdragon dac). If you buy it thinking it is a dac, I bet you are in for a disappointment as your htc 10 doesn't support usb c over analog so that means no sound at all since the adapter has no dac
