Yes but certain sound characteristics works well that plays along with the sound signature of the X3. I noticed phones that are cooler in sound will mesh well with the player as well. CKN70 for example sounds really nice on the player. Detailed phones using BAs, carbon nanotubes or titanium drivers.. Phones like the HA-S500 with good detail works well even with the big bass. GR07 BE edition is another example. And the VSD1 is not too colored to the point where it will sound off and those have a solid amount of detail too which adds to how it plays.. Phones with a V signature also works well with the X3 because the full deep mids of the dap will pull some of them mids forward a touch giving some balance to a V signature phone.
I suspect the M50 to work pretty well with the X3 for example.. Both Daps will sound nice on all types of sound after all if they made the players to only sound nice for certain phones and not others that would not make for selling too many of them. The DX50 sounds fantastic using neutral phones as well and detail guys will prefer that but they truly shine with phones with fuller forward sound and a bigger bass end. It off sets the players sound characteristics and adds musicality and better synergy. The worst synergy of the X3 is when you have a forward sounding phone with big bass AKA CKS1000...Can get a bit too hot and heavy..Which in this case is not a good thing.
To get the best synergy however the X3 absolutely shines on a more neutralish type sound. S2/ GR07/ RE-400.. I got confirmation from several X3 owners on the X3 thread noticing the same effect. Monitor type earphones and headphones absolutely brings the musical qualities of the player out in full force..
