Speaking of which, the Oppo PM3s, Bosshifi B7, Bosshifi B8, and some Philips A1pro/27s came in.
Damn they all sound good. I've been comparing them and here are my notes in comparing all 3.
First off, soundstage on pretty much all of them suck. The B7's are suppose to be semi open, but the soundstage is marginally better at most.
Now for the individual details I can share for each. First the A1's:
The A1s are on ear type, but one of the better sounding on ear types I've heard next to grados (don't own a grado but have heard them). For $20 that they were on sale, I would say they were a steal. I just hate their proprietary cable and connection. Ugh on that. Also they are on ear, so they aren't ideal for my comfort level. The band goes from real small to pretty big in adjustments. This is cool because it is the first headphones my 3 year old can actually first correctly on his head. Not that I let him wear headphones much, but he is always trying to imitate me. Still from a comfort perspective they are decent with mildly tight clamping force.
Sound: Good bass thump. Bit of rumble for bass decay but it's very slight. Sub bass is there too. Mids are forward and treble is a bit pronounced. Doesn't take much to drive them. Nothing sounds veiled or recessed. Might be a tad rough on treble for some, but I like them. Treble is the brightest of all the 4 I'm listing here. Closer to V shaped, but with the mids not really being recessed they sound like a hard U shape is what I can describe.
Bosshifi B7:
Comfort is nice, but the stock pads are not really around the ear. They certainly touch and may cause some issues with people. Mids are extremely forward. Treble there, but not harsh. Bass is tighter than the A1. Not as punchy though. Bass is deep and sub bass is there. Easy to drive. Nothing seems recessed or veiled to me. Overall very nice sounding. Otherwise these cans feel and way more expensive than the $50 I paid. Fairly light clamping force, less than the A1, but more than the others.
Bosshifi B8:
Why is the headband on these like half an inch longer than the B7? The band is frikking huge! Also, I'm not sure if mine was crosswired, but my right is left and my left is right on these. They are very comfortable though. The earpads are bigger than the B7's, not as big of an opening as the PM3s, but my ears do get inside these all the way. They do touch a bit inside though. Sound wise they have a bit more bass impact than the B7's. Same tightness on the bass though. Treble is brighter than the B7s. Making it more U shaped where the B7's sounded more mid forward. They are both U shaped sound wise, but the B7's sound flatter overall. The B8's are certainly brighter. but just slightly less bright than the A1s.
Oppo PM3:
The bossshifi headbands feel like they are trying to copy the Oppo PM3 headband and come really close. Not quite, but close. Seriously close. Earpads on the PM3s are bigger. These are very comfortable overall to me. I touch still slightly inside, due to my big ears, but not enough to bother me. They are slightly harder to drive than the other 3 so I have to turn of the volume a bit. The PM3's are certainly warmer and mostly flatter in comparison to the other 3. Everything seems where it should be. Nothing is forward. Smooth is all I can do to describe them. Neither mids nor treble is forward. Which means if listening fatigue is a thing for you then these would be least potentially fatiguing of all 4. Otherwise bass is tight, no rumble, and blends right into the mids properly. The do sound the "best" of the 4, but just barely to me. This part is very subjective here I'm going to admit. The smoother and warmer signature is just a bit more what I like. Reminds me of my broken in M560s (open config) without the soundstage. Edit: just looked at the frequency response graph on the PM3's from innerfidelity and glad what I hear is what matches up to the measurements. The PM3's are bit more rolled off on the highes, but aren't bad at all on it. Just not nearly bright or harsh on highes as many other HPs are. The other 3 I reviewed are much more pronounced on the highes than the PM3's, but not by a whole lot.
Seriously all 4 are spectacular cans. In a blind I would have believed the bosshifi were $300-$500 cans like the Oppos. Except the cross wired B8's. Seriously What is that crap China! It doesn't affect the sound, but it just peeves me a bit. Heck even the A1s sound like $100+ cans. I'll have to listen to these more. The Oppos I picked up from a fellow member so they have some burn in too. The others are literally brand spanking new though. They will probably sound even better with some burn in, but holy crap they sound damn refined now. Paid about $50 for each bosshifi and $20 on the A1s. Regret nothing on those.

Couldn't get them all hanging in that screenshot as I don't have enough hooks. So some I took on my dusty desk. Ignore the pet hair
Oh and those are dead logitech gaming headsets in the back I was intending to try to fix.
