Hifiman HE400SE DAP or Smatphone

[Xaviedie]

Hello, what walkman for the Hifiman HE400SE audio headset from 25omhs?

Smartphone: ? LG G7Think => output impedance raise = cross out

DAP Hi-Res: ?

Headphone amplifier (without dac):?

My goal: Mobile use at home = Smathphone or DAP Hi Res with low output impedance => Hifiman HE400SE at 25ohms, it is for this reason

The LG G7 with Quad DAC has has an output impedance of 0.8Ω across the entire spectrum:

That's more than low enough for 25Ω headphones.
