Hi all! I have the interface of the title, and I want to buy the dt990 headphones, I am afraid that due to their impedance they do not work well, on many internet sites people say that they work well without an amplifier but I would like to know their opinions. I have seen videos of people who use headphones with laptops and cell phones without without and external amp/dac and they say they work well, I find it hard to believe that a Motorola cellphone has a more powerful amp than an audio interface, that's why I am positive that they work well, but at end i have no idea.
Just for reference, I usually use a sony mdr-zx110 with the volume at 50% and when mixing I use them with the knob at 3 clock.
If an amplifier is absolutely necessary, would it be nice to buy the behringer ha400?
