Balanced ?

as far as I know, the major differences are that the wiring was reconfigured to support balanced vs regular 1770 can only support single ended, and the tuning was tweaked a bit to tame some of the treble compared to the original. Additionally the impedance is significantly different at 32 ohms for the 177x vs 250 ohms for the 1770 pro. Also this one doesn't come with a case while the original 1770 does if you care about the case. Note about the balanced - there's not a lot of options to get a balanced cable for this headphone because the pins are different than the regular 1770 pro. Common suggestion has been to get one made from Hart Audio Cable; not sure if other places have started selling compatible cables yet.

The difference from 32 ohms vs 250 is significant, as you said. Apart from the fact that this Drop version might not need an amp as for 1770, are there major differences from a music-listening experience? I am not sure why Drop made a drastic difference to the impedance, unlike the Senn HD650 and 6XX headphones.

Excerpt from their product launch post "The DT 1770 PRO version was originally designed for mixing desks and professional audio interfaces. The PRO version needs more power to operate the drivers and was designed to show flaws in recordings. From the Beyerdynamic website: “The DT 1770 PRO are the ideal headphones for live acts as the extremely high efficiency drivers assure a perfect listening experience in the loudest environments.” We worked with Beyerdynamic to modify their DT 1770 PRO version and make it better for our community and the kind of music listening that we do: from a sit-stand desk, at a coffee shop, or around the home." Essentially they wanted to create a portable version of the DT 1770, one capable of running off of people's phones. Personally I've found that a desktop dac/amp still does make it sound a bit better than running it off my DAP, but the difference is nowhere as big as the Sennheisers. I haven't heard the original 1770s so can't comment on the differences in the sound caused by the change in impedance, but several of the reviews compare between the two, so those might be of help.

Thanks very much for the excellent inputs. I am browsing through other answers too, in the meanwhile. Thanks again.
