    Senn HD800 Ultimate, "Maxx" Mod

    I only made one version of the hd800"M". Just this week I finished the latest version, "hd800M2", which differs only with my own version of a "center insert". It was created using an opposite ideology of NOT hampering or muting sound, but instead "enabling" the sound, creating more linear...

    Senn HD800 Ultimate, "Maxx" Mod

    While I made the HD800SM version, which uses an HD800S drivers, I had disected and scrutinized an HD800S driver. So although I don't like to use these control methods, I decided since all the variants are using the center insert, I will make my own version to actually improve the Frequency...

    Senn HD800 Ultimate, "Maxx" Mod

    I have just refined my modification process and ordered new tools to reduce my latest mod safety margins to estimated 90% instead of 50% or so. Have to wait till parts come in to try another mod. If this works, my modification process can be made public. I am also still interested in the 8XX...

    Senn HD800 Ultimate, "Maxx" Mod

    After much recent investigation and contemplation, I would not replace any broken units with 8XX drivers. It is my determination that the most refined/robust driver version Sennheiser made, was the driver inside the 820 unit, which is the 800S driver. It's just easier to work with an 800S. The...

    iBasso DX300 Qualcomm Snapdragon 660 Octa-core 6GB RAM 128GB ROM NEW Firmware 09/29/21 1.04.305 !

    I feel this unit is very polished in software at this late stage. Because of the dx300 choice of it's 4 chip topology, it can use Neutron at maximum overclock PSM to DSD settings, where as with the dx320 still has some compatibility issues with Neutron as of Aug, (although I haven’t checked last...

    Official Unofficial 8XX Discussion Thread - UPDATE SENNHEISER HAS BEEN SOLD!!! GT(heck)IH

    Have you noted any longer break in period with 8XX,? The hex pattern version was a latest/ newer version. I did notice older, early model 800S does not have proper lettering on headband, and so actually may have the older design body.

    Haha you can lend it to me as the first guinea pig for testing to see what if can be done. It guaranteed to not be the same 🫣🙃, lol

    Senn HD800 Ultimate, "Maxx" Mod

    I have decided to look into this, and attain a 8XX, in order to make a true conversion to 800S, and then update it to an HD800SM. Will post measurements & pics along the way to record this here. Edit** After much contemplation, I realize it's too much work and instead will just optimize the...

    Official Unofficial 8XX Discussion Thread - UPDATE SENNHEISER HAS BEEN SOLD!!! GT(heck)IH

    It is quite possible I can revert this into an actual 800S. It's a bit more than just removal of that grill damping, but looks very possible since I been working on these drivers so long. Looks like tha last drop price permanently devalued the headphones to below $800, even though it still...

    Senn HD800 Ultimate, "Maxx" Mod

    I happened to do a search for HD8XX unboxing, to check how package if sealed, and came across a comparison video. I was under the assumption that the HD8XX was supposed to have a bass benefit, but upon listening to this video, it turns out that the HD800S actually has a bit more subbass than...

    I was under the assumption that the HDXX had more bass than the HD800S, but after listening to this video, it seems opposite. You can hear a touch more subbass on the 800S. I will have to verify this, but you can hear for yourself:
