Hello, I want to power two headphones at the same time, an HD600 and an HD650. Currently I'm looking at the Behringer AMP800 and the PreSonus HP4. One of the problems I have with them is that they both have very big output impedances (47ohms and 51ohms, respectively).

Is it possible for the O2 to serve them both at the same time using a headphone splitter? But I think the HD650 would be louder than the HD600 for the same level. How do you guys propose I solve this?

You could also suggest different products. Budget is ~150USD. I want something that could power two headphones, has inaudible noise, has an output impedance of < 2ohm, and adds no coloration to the sound and has separate volume control for each headphone output.

Thank you and good day.

I use a Behringer HA4700 headphone amplifier sandwiched between Beyerdynamic DT 770 Pro 250 Ohm headphones and an ASUS Xonar DX soundcard.
These hardware components receive 16bit - 44100KHz .wav files which i created using ExactAudioCopy via Foobar2000 and the ASUS Xonar DXs ASIO driver.
This hardware / software / input signal configuration has kept me very satisfied for over a year now and i do not believe it is possible to improve apon it without
totally annihilating the law of diminishing returns.


Unfortunately, it is too big for me. I can't find it locally and shipping would be too expensive.

The amp800 really does spec a 47 ohm output impedance and they provide power specs at 100 ohm load so I assume its just not very good. Would handle high impedance phones well enough though.


Will the 47ohm output impedance make an audible change when used with the HD600/HD650? I would prefer if everything is in one box.
