Headphone splitter and impedances

[ras52]

One for the brainy people who understand impedance, buffering etc. :-(

My setup uses a modest interface with a single headphone output. When I've brought in a singer I've previously used one of these



and given them my "louder" pair of headphones while used my "quieter" pair. Having mislaid the little beggar I'm now looking at replacement options. Am I right in thinking that the "loud" pair was sucking signal from the "quiet" pair, in a path-of-least-resistance way? Am I also right in thinking that I'd get the same result if I got a passive splitter like this

and that I'd need to get an active unit like this

to be able to balance both pairs?

Thanks in advance, o clever people!

I dont know the detail , but maybe one set of headphones is more efficient than the other , and I would reckon the active headphone amp would be exactly the way to go . that way each signal can be set to the required level independant of the other

ive got a powered headphone splitter similar to the one below, hey are about 20-30 quid and well worth the money imo.
you can vary the volume between the two of them to whatever level works best.

Thanks for the input. There are half a dozen or so active splitters on Amazon starting from around £15, so I guess it's down to which one's the prettiest

mine is an A.R.T one and it has served me well for a number of years now

I've gone for the CAD Audio HA4.
