No bloated bass with the Ori pads, and no joy with the Alpha pads.....

The Ori pads are very close to the Mr Speakers angled pads, Ori pads have more ear room, and don't bring the vocals as close as the Mr Speakers. I do use the Mr Speakers angled pads on my fully Lawton modded D5000, D7000 and THX00, work best on those. Ori pads on the HE6 just more comfort and...

You might give ZMF Ori pads a try, I found them to perform very well on my HE-6...........

Do I need drivers if I don't use the USB?

I reterminated mine with mini xlr for Audeze/ZMF, but HD800 termination may be very difficult because of the wire gauge, and four wires to each connector.

+to US don't forget Tariiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiif

I puchased pair a few months ago, as you describe, minus any scratch, paid $300, if that helps!

"Hello squeaky right cup!" :ksc75smile:

After this disappointment, no more Massdrop purchases for me! Poor quality from trying to make the quick buck?

You need the converter you have linked, or similar.

My pair had clicking in the left cup, no music playing, or with music playing, but the problem is a mechanical build problem. They are going back to Massdrop. Same issues were noted with some Elear and even Utopia.

I thought I sold you a pair of Tung Sol 1626, maybe someone else?

Got the adapters for the 12B4A's. Trying to get initial impressions using my Denon/Fostex w/Lawton mods and cups. Noticed so far, bass has tightened up, more pop and texture on the low end. Also, more detailed than the Tung Sol 1626, in my setup. don't think I will be going back to the 1626...

Has anyone contacted Massdrop about this? I contacted the seller from Ebay, where I purchased mine and I am having some problems getting this resolved. I requested a return back to the seller.

I am having clicking sounds on the left ear cup, appears to me to be a mechanical issue, not in the music but coming from the headphone cup itself.
