Yeah, I listened some more with some different cans.  It's not that the Fulla is bass light, it's that it has more treble going on than the others.  It seems like it's a bit much. 

I dunno if there was a silent revision, firmware update or some source setting/synergy is off, but that's not quite the sound Marv, OJ and I heard at our meet. Perhaps the newer drivers are having an effect?

Excellent reference.

I'll have listening impressions of the Headstage Arrow 5TX (Enhanced Bass) sometime tonight hopefully.

This thing is tiny. I have no idea how he crammed so many features in here.

It's here. It's tiny.

I don't know how the F all of this got packed into something of this size.
 
So far, it sounds surprisingly good. Perhaps not as clean as the Vorzuge, but... well, look at a graph:
 
(See below. I don't know how to put image attachments inline because this BB system is from the 1900s.)
 
WTF. Bring on the BASS.
 
I have my Fostex TH600s shaking on my head right now.
 
Treble boost is 3dB or 6dB.
 
Bass boost is all over the place based on the combos. The Teal colors are at the Low frequency, Purple colors are Medium frequency, and Red colors are High frequency (Upper Bass).

Geek Out (450)

Nobody? It was a serious question. Portable devices, Android, is all part of the sales spiel. I haven't tried this with phone/tablet yet, but certainly will do, but there is no way I would want so much heat next to my phone. Or my body.

So are these devices used for portable in the sense of pocket/commute/travel, rather than in the sense of laptop?

Get a pouch for it big enough to put the USB connector cable as well. Voila! I think for the iPhone you need the CCK but not sure about other smartphones and/or DAPs.
