    Hello.
    I am just about to buy good headphones for amateur use. I am thinking of the DT 770 PRO model.
    The headphones will be used in conjunction with the ONYX Black Jack audio interface (according to the specification: 8mW into 600 Ohm) when working with a DAW (Ableton Live9) or will be directly plugged into the instrument - Kurzweil PC3x.
    And here I have a question whether with such an application and configuration (not wanting to invest additionally in a headphone amplifier) I should choose the DT770 in the 32, 80, 250 Ohm version.

    Thank you for your answer and best regards

    The 8mW is surprising :-) Until I checked my Art Headamp 6pro, for comparison what it looks like:

    Maximum Output Level
    600 Ohm Headphones @ 1 KHz ............................................ .... 150 mW
    32 Ohm Headphones @ 1 KHz ............................................ ...... 500 mW
    8 Ohm Headphones @ 1 KHz ............................................ ........ 150 mW

    8mW seems to be very little even at 32 Ohm. I don't want to count how many mW can come out there, but probably less than 30.

    From what I read about DT770 32 ohm:

    Power handling capacity. . . . . . . . . . . . 100 mW

    I can't see it. It may work, it may not be loud. I would think about an external headphone amplifier.

    here is the specs of my black jack:

    maybe I misunderstood something ???
    I sent quite a few inquiries to stores selling DT770 PRO and received completely different responses: from 32 Ohm to 80 Ohm will be perfect to only 250 Ohm for my configuration.
    So I'm even more stupid now than I was before bringing up the problem.
    Best regards and I hope for valuable advice on this forum.

    @ b00l3r @ 2ygmunt DT770PRO 250om is hard to drive before you hear anything, most headphone amplifiers will distort.
    I recommend buying the 80om version, they sound practically like 250om.

    The 250om is a relic of the past, associated with recording several people on one headphone track, connecting 10 pairs, the amplifier worked at 25 ohms, so it does not palli.

    At home, you are unlikely to connect 10 pairs at a time.
    The 80om version is sound almost indistinguishable. And you can connect two pairs in parallel without losing quality, and they are easy to drive, they sound more accurate in my opinion than the 32om version.

    Thank you very much, because basically I'm still hesitating between ver. 80 and 32Ohm. As far as the volume of Blackjack at 80Ohms is concerned, I am calm (now I have some 32Ohm headphones and they are loud with a lot of reserve). I am more concerned if it will be too quiet when plugged directly into the Kurzweil (because it has a really quiet headphone output).

    It's good that I didn't have such problems in my life :-)

    I am using this DT770 series on a daily basis, so I will say.
    The difference is comparing the 1/1/1/1 32/80/250/600 ohm versions - I have them all, although I prefer 32ohm. The higher the impedance of the cartridges, the darker the sound in my opinion. 32 is a good version in my opinion, but sometimes there is a problem in the cartridges - the manufacturer in this version does not pair them with an accuracy of 0.1 ohm, only the service - when you send the headphones to them for this purpose. Fortunately, they send you up to 48 hours so it's not that obnoxious.

    So I think I will go down to the 32 Ohm version, the more that while browsing the Internet, many people say that the low frequencies are too exposed in the 80 Ohm version (but the opinions are different).
    I am waiting for further guidance and thank you very much.

    @ 2ygmunt The versions with higher impedance sound more even. And the DT770M has more bottom.
    @ b00l3r Somehow I did not notice that the 250s sound darker than the 80s, maybe it is worth adding a better amplifier? In addition, the 600om version is a completely different handset than the DT770PRO.

    @cookie Monster what do you call a better amplifier? I have "paired" preamps in the Drawner Mc2.1 in the Rme UFX and the Art Headamp6 pro. It seems to me that everything works fine for me. Anyway, all the devices at once doubt would collapse :-)

    I just propose to go to the salon and compare. The difference is not very appreciable, but it is.

    @ b00l3r what do you mean by paired?

    Two preamplifiers with comparable parameters - to have a similar amplification environment - that's why I used quotation marks - similar. The manufacturer declares that it is the same, but I do not know people who have tested them for voltage.

    What do you call a better amplifier?

    The Drawmer has two headphone outlets and two separate opamps to it.

    Better, I call it the one with no problems with the top. They just sound even, regardless of the load impedance.

    Okay, and I still read and read and ask and ask. And somehow it turns out that more people are delighted with the 32 Ohm version than the 80, that they play more "fun" than "faithfully", which in general is an advantage.
    In turn, most sellers and stores recommend the 80 Ohm version.
    Knowing the conspiracy theory of history, I start to wonder if the 80-ohm model will not slowly go out of date, replaced by 32, and hence the desire to sell this model by stores? :) .
    The 80 is also tempted by velor on the headphones, which is certainly more pleasant when used for longer (plus glasses).
    So, I am still waiting for helpful advice and suggestions.

    @ 2ygmunt I have and can recommend it to 80 people.

    Let me reheat the topic, because the BEYERDYNAMIC CUSTOM STUDIO 80 Ohm model has appeared on the horizon.
    Does anyone know them, listen to them? How do they compare with DT770 PRO ???

    @ 2ygmunt buy yourself DT770PRO 80om and don't mix it up.

    I also hesitate between the 32 and 80 volume versions, but I prefer a bit dark, fun sound and I don't know which one to take: /

Topic summary

The discussion revolves around selecting the appropriate Beyerdynamic DT770 PRO headphones (32, 80, or 250 Ohm) for use with an ONYX Black Jack audio interface and a Kurzweil PC3x. Users express concerns about the low output power of the Black Jack (8mW into 600 Ohm) and its ability to drive higher impedance headphones effectively. Recommendations lean towards the 80 Ohm version, which is noted for its balance between sound quality and compatibility with the audio interface, while the 32 Ohm version is favored for its fun sound profile. The 250 Ohm version is generally considered difficult to drive without distortion. Users also discuss the sound characteristics of each impedance, with the 80 Ohm version being described as more accurate and the 32 Ohm version as having a more pronounced low frequency response. The conversation includes comparisons with other models, such as the Beyerdynamic Custom Studio 80 Ohm.
