Thanks to ModHouse Audio for sending out this loaner that I’ve kept for just a bit too long. Sorry about that, but I really enjoy these.

The Argon is a T50rp Mk3 mod, and thus is built like one. Construction is nothing exceptional, but it won’t fall apart anytime soon. Externally, what has changed is that the backs of the cups are all blacked out with an “M” logo on the bottom of the cup face, a wonderful comfort strap in either deerskin or alcantara is added, and the pads are swapped out. This pair I have is using ZMF Lambskin pads. As pads do impact sound significantly, if you order a pair with any other pads, you will get different sound than I describe in this review.

Being a T50 mod, these are relatively hard to power, combining that with a fun sound that demands you turn the volume up a bit, you will need a relatively beefy amplifier to pair with these.

Comfort is just spectacular. They are not heavy, and what weight they do have is distributed very nicely by the comfort strap, and the ZMF lambskin pads are simply the nicest leather pads I have ever used. The only issue is that they can get a little hot after a while, but that is just a fact of leather pads.

Overall, the sound of the Argon is warm, wide, natural, and just plain fun, but without losing out on detail. Bass is very present, but far from overwhelming, and has good definition. Nothing down low ever sounds bloated or overdone, instead sitting happily in the spotlight while still leaving room for the mids and treble. Individual bass notes are very well defined and controlled, while still managing to have an indescribable energy to them that just pulls you in. The midrange, while out the spotlight, is still very good. Vocals sound very natural, if they do have a slight low-tilt to them. Again, there is some strange quality about them that pulls you into the music: just while writing this paragraph up to this point, I have already paused to experience the music for a while a few times. Overall midrange tonality is good, though there is a bit of a low-tilt, as previously stated, which I personally really enjoy. The treble is slightly recessed, which is something I typically dislike, but it lends itself so well to the bass-focused sound, and really did not take away from my enjoyment of these. Treble is well-defined and clear, and everything manages to sound tonally natural. Detail overall is a bit behind what their price point would suggest, but their fun and natural sound more than makes up for that.

Here we get to one of the Argon’s greatest strengths: soundstage and imaging. These are fantastically wide, and have fantastic imaging. They both are just staggering, and from a closed headphone no less. You really just have to hear it for yourself, these can present themselves as grandiosely enormous, and perfectly define a point within their enormous soundstage. These would be phenomenal for gaming.

Plenty of warmth plus natural sound throughout the spectrum plus enormous soundstage plus fantastic imaging plus excellent comfort equals a very pleasant headphone. I honestly can find little negative to say about these. If I had to really complain about something, they can get a little bit lost when there is a lot going on in a song.

Do I recommend these? If what I’ve described has you interested, then you will likely love these, and you can always tweak them with pad changes. At about 300USD these are definitely a good buy, though you can spend more on having them wired up for balanced, a balanced cable, and a decent case, though I don’t see the point of a case, as it would take a serious device to power these portably.
