AzraelianWe are shipping the High gain version on this drop. We include an impedance adapter/attenuator for IEMS. The amp has a linear power all the way up to 600 ohms (2V). I tried some Beyer dynamics 600 ohms, the sound was pleasing but its pushing the limit a bit. As far as ultra portable amps go, you won't find more powerful but your 600 ohms headphones will be playing decently altough a bit underpowered
Pierre111Beyer DT880 and DT990 600 ohms are what I have, I use them in door because of the semi open/open back but I never thought I would see portable amp for 600 ohm at this price range. Thank you.
AzraelianGet this for the iem's and lower powered headphones. Get the Fiio Q5 with AM5 amp for the powerful stuff if you want a bluetooth friendly device :) This will work for the 600ohm headphones, but like they said it is pushing GET to its limits to run those.
SyrahcazThe very last drop was the Hi gain, The first 2 drops where lower gain. to make it clear if you paid the current 85$ price you have the hi gain
