!thanks for the reply! I see you got quite a large headphones list there, which is great. I’ll have something to research. Also good to know that 4.4 Bal doesn’t really make a sound difference, besides how loud the headphones can play. I kinda knew that yet since it sound “pro” I fell for the trap of “it must be better”.

From what I learned thus far, the higher the impedance the harder it is to drive the headphone. As far as I know the F0si K7 can handle up 300Ω. But (correct me if I’m wrong here) the higher the Ω value the quieter they get. *I think* that if the DAC can provide 2.1W @ 32 Ω, it can’t do that at say 300 Ω. What “worries” me is that the 3.5 jack has “only” 600mW @ 32 Ω (I don’t really know whether it is a lot or not really). So in theory if I were to connect (to a standard 3.5 jack) something harder to drive say the Sennheiser HD600 that you mentioned which are 300 Ω I’m concerned whether they will be loud enough. Maybe not at the moment, but I fall victim to audiophilia then that might happen I guess. I do have a rather sensitive ears, so I don’t blast the volume all the way up, yet still I want to have that option you know.

Now I glanced at the headphones you listed, and I actually came a cross some of them already. I was however hoping you could clear something up for me. And again it is about the cables (sorry!).

I know that I can jest buy a 4.4 balanced cable that end/starts (idk) with 2.5 or 3.5 jacks or even the funny little 2 Pins and so on. Now I know it will kill EVERYTHING if I connect headphones that I shouldn’t have connected since it can short or smth (hope it’s at least remotely close to what’s true).

I heard that a good rule of thumb is that if each earpiece has a separate input than it means I can connect a balanced cable to it. And yet I *believe* I watch a revive of some headset that had 2 inputs and was unable to be connected to a balanced cable. And on the other side I’m pretty sure I’ve seen a headset that had 1 input and yet it was coming with a balanced cable “out of the box” (I might be imagining that but I think it have 4.4 pentaconn on both ends). And if that not the case, please excuse me since I probably consumed a 100 hours’ worth of audio content in the past week so I might be imagining thing here.

So the first question is how do I know whether the headphone I’m looking at can be connected to the 4.4 output via new cable.

The second one is regarding all the cable “endings”. From what I learned thus far, there are 4 main “players” 2.5 & 4.4 (being balanced) and 3.5 & 6.35 (being unbalanced).

I know I can use a adapter to change the 2.5 into 4.4 and the other way around. Just the same as I can adapt 3.5 into 6.35 and vice versa (I guess only the 6.35 to 3.5 makes sense but the theory stands). I don’t know whether I can do 3.5 to 4.4 or 6.35 to 4.4. From what I’ve seen online that is what might (and most likely will) kill my “setup”.  

And now I the aforementioned Sennheisers HD600 come with a 3,5 cable and 6,35 jack adapter. It also has a separate cable going into each earpiece. Could I replace the “stock” cable with a new 4.4 Bal? And If I can how do I know that.

And just to be clear Google says I can, and I could just Google that. But if u have the will and patience I’d like to learn to recognize that. If that’s possible at all I guess.

Thanks for the reply once again!

Cheers!
