Comparison and review of the new Beyerdynamic 770 Pro X and the original 770 Pro (plus FiiO JT1)

Just a note since I did not really talk about that in the review: The 770 Pro X has 48 Ohm and is pretty easy to drive, same as the other Pro X models. Did not really want to get into detail regarding that since modern closed back studio headphones with dynamic drivers tend to be easy to drive anyway (makes sense if you need one on the road or something), different Ohm-Versions is a thing Beyer does not do anymore and it is not really worth talking about in this case (different with Planars of course who usually need more power). I also have a few other reviews on my channel about the open back Beyers where I talk more about that. :) 0:00 Intro 1:02 Design and build quality 3:57 Comfort 6:03 Sound - Intro 6:12 Sound - Bass (+bit of lower midrange I guess) 9:00 Sound - Midrange 9:58 Sound - Treble 13:15 Technicalities 14:01 Professional use? 16:13 Comparison with the FiiO JT1 18:40 Outro
