I've decided to use 50 mm drivers with 24 ohm impedance (16 is fine too, "DAC" outputs 26mW@32Ohm and 52mW@16Ohm, so it should give ~39mW@24Ohm). I sometimes use headphones as low-power speakers (on max loudness with them on neck).
I found these three choices:
52mm Headphone Speaker Unit For Denon AH D9200 24Ohm Deep Bass Nanofiber Free edge Hifi Stereo Earphone Repair High quality 2pc|Portable Speakers| - AliExpress
Hifi 50mm Headphone Speaker Unit For Bluetooth Headphone Diy 24ohm High end Headset Driver Earphone Repair Parts Deep Bass 2pcs|Portable Speakers| - AliExpress
50MM 24/300 Ohm Headphone Speaker Unit Pure Copper DIY Audiophile Loudspeakers driver for denon AH D9200|Earphone Accessories| - AliExpress
Sellers gave me attached frequency response graphs, but I can't decide which one to buy. I mostly listen rock music and watch videos in headphones, so that should I choose (or maybe some other proposals)?
It's also quite strange that gold ones have exactly the same graph's shape but different frequency range on graph. Though drivers look very similar.
