Ok cool. I'm going to wire mine in this way and see how they sound.

Dunno man, other than black vs red wire looks looks pretty similar to me. Mine is a little messed up from my less than perfect soldering and my photo is not great. Do you have the same Havi as bhazard? Could you check if the red wire is in fact just a wire?

But the isolation looks weird, too thick and too short. Compare it to the ones on my photo. Also wires in mine are copper. Edit: Maybe they just used a higher quality wire in pros.

I know that. I'm just not sure if there isn't anything else there. Also on the left I can see three strands and they're separated so it's kinda strange. And the insulation looks too thick for a regular wire.

The red sleeve looks to thick to be just a regular sleeve of a wire, there could be some kind of component under it. But on the other hand it looks to thin for a resistor, at least the one I have.   Can you somehow see what's under the red sleeve? Maybe you could move it to the side or...

Yea it does, you can totally see a portion of the other driver in the opening next to the first driver. Can you see a black foam or something else (white plastic, paper)?   So you meant there's foam in the actual shell? I don't have any.   Resistor was in series with the drivers (connected...

Thank you, it's very interesting.   Drivers are connected in series, in my version they’re connected in parallel. Visually they look identical to mine (or very similar).   Can you see if there is something under the red sleeve, or is it just a wire?    You can also lift up the left driver...

If you don't want to mess with soldering, you can try to connect leads of the resistor using something conductive (a copper wire or something). Just a thought.

No, mine are in different condition than out of the box . But we've established that the only difference between two non pro versions is different filters/dampers on one set of drivers. More interesting would be knowing how they differ from pros.

I used double-sided tape to hold the glass and it works perfectly.   Tried Havis with resistors. Without them soundstage is bigger, there’s more space between instruments. Treble has more energy, sounds more aggressive. Vocals also sound more aggressive, with resistors might sound better, more...

That sucks, mine came right off, just lifted it with a knife.   Couldn’t really A/B them with and without resistors, so I might be full of it, but soudstage seems much wider without them. Hadn’t noticed big changes in sound quality, but it was a muddy mess regardless (before filter removal)...

Just the one closer to the nozzle, I'm going to try the other one later. You can also just put it in the nozzle, gonna try that too.

Haven’t found any filters to use. Instead I tried cotton from a cotton swab with pretty good results actually. I’m going to experiment with thickness and different material.     I’d like to get some filters/dampers with different impedance to try. Mouser sells Knowles dampers, but shipping...

Green, brown, 2x gold stripes in that order, so from what I understand should be around 5,1 ohm (pretty sure it measured 5,5 but I might be remembering it wrong). If you have a soldering iron you might want to get rid of them. I like my B3 better without them. 

Tried with just foam filters and the mud came back, they definitely got to go.   Edit: peter123 do yours have resistors inside? Green, brown, 2x gold stripes?

So yours must be this third less terrible version    I'm kinda digging them without any filters, but they're kinda bright, a little weird sounding. Gotta experiment with some filters. Maybe will rip some out of other iem (might have some broken brainwavz or something) or buy some, I dunno.

Guess we have different versions lol. Mine had white kinda papery filters. Where both of yours foam?

I'm experimenting with them right now, lost one screw already :). Removing the white filters in front of the other drivers made even bigger difference I think (dunno why I thought it didn't before).    I owned Phonaks PFE in the past and by changing similar filters you went from super...

I doubt just one resistor would change the whole thing into pros, but as I said I'm no professional. Still some investigation into pros internals wouldn't hurt, would be awesome if you could do that. Resistors are color coded so you can visually determine the resistance. But to be clear even...

I got my Havi B3 a couple of days ago and it definitely wasn't a pro version. I decided to open them up, was hoping that they had the same drivers as pros and removing some filters or something would turn them into a pro version :). I'm no audio engineer but with multiple drivers one would...

Yeah, released in 89 or 88 I think. Love technical thrash like Watchtower, Coroner, Mekong Delta buy DI is just on another level.

You can find the most obscure stuff in LOSSLESS on a certain russian tracker. Just sayin'. Listening to Deception Ignored by Deathrow in lossless, best thrash album ever.
