    I'd be interested to get a list of output impedance values for DAPs and mobile phones. Can anyone give me a hint where to look?

    for phones, some Chinese or Korean websites will often measure impedance, but often you get lucky just by typing the model name + impedance in google.
    a place with clear list of impedance by DAP and cellphone, I don't know who still does that. Goldenears used to do it, but I don't think they have reviewed any portable source in the last years. :frowning2:
    https://www.seeko.co.kr/zboard4/zboard.php?id=m_device here they usually measure the impedance but it's not offered as a list like you want.
    a few other places try to measure impedance but I don't know of anybody doing measurements and having a big up to date list of devices. hope somebody will have that for you.

    Is there a wide enough range to make documentation really necessary?

    thanks all for the hints and links.

    Maybe I should rephrase the question and ask for a range of impedance rather than specific values?
