Noble K10 are my mainstays yet have others here for review (forthcoming). Maybe it is 11 hours and change, yet 9 to 10 should be the norm for the R version. I don't do much with headphones, just not really my thing even though I have the OPPO and others here. Yes I do use cans, yet not in any appreciable amount.
Look, if you want long battery life and immense flexibility, nothing beats the Sony NW-ZX2. You'll lose in amp capability and incredible imaging of the Questyle QP1R. Of course a small USB power bank solves battery life issues many of the DAPs have and many here regularly stack things together. How long a battery life do you need? Do you listen to TIDAL, Deezer or other streaming? Do you desire pulling files from the cloud or NAS drive? Do you need touchscreen? Is Bluetooth important to you? What features must you have? What features can you live without? What are you willing to pay for each needed feature? Please break down your feature/cost.
I want the QP1f with the small fission reactor.....A couple hundred years of battery life.....
