Nope, this amplifier will put out a measly 0.5W! How will it power anything? I am told certain headphones require 15W amplifiers these days to be "driven". Maybe I am overconfident, but I think this amp will sound better than the sneeze glass amp.
For those headphones, I'll use my Sansui au alpha 907mr or Redgum Rgi120enr. I'm actually not keen on a combination speaker/headphone amp. I like to keep those 2 functions separate. I.e. a dedicated integrated amp or separates for stereo and headphone amps strictly for headphones and a dap for iems but I don't use iems apart for my Senns Momentum wireless earbads.
