Not wise using that sort of material in our climate. I find these plastics last about 12 months before decaying.
I have a pair of Beyer DT-311s that are in good condition after nearly 30 years, while a Sennheiser set had the yellow foam turn to dust after a year.

I think the DT990 Pro is a 250 Ohm impedance, so it need some voltage swing to go loud.

The FIIO K5 is specified at 1.5W into 32R and 150mW into 300R. This means 6.7Vrms into 300 Ohm, which will be very loud and more than most PCs can manage

Do you have a figure for the amplifier output resistance?
Headphone treble balance is affected by this.
