JM Audio XTC^2.5 Euphoric Xtreme Trip Limited Edition

General Information


The XTC^2.5 Euphoric XtremeTrip is JM AUDIO's flag ship closed back. The XTC^2.5 utilizes precision cut solid blocks of various exotric hard woods which are carefully CNC machined - where by they are cut and bored with special amphitheater internal cuts, and include five tuning slots and ports which allow a user to further tune the closed back by increasing or decreasing bass or detail similar to the way fluted air instruments change pitch by covering or opening holes in the instrument. The XTC^2.5 uses our own proprietary JM Fractal Porous Graphene Carbon™, JM Fractal Fiberglass Mesh™, and JM Nautilus Fractal Spiral™ technology for a wide spread out soundstage.



The driver we use is a custom magnet forged/cast not stamped basket utilizing N52 magnets and a occ copper coil- beryllium dynamic driver- carefully machine matched and then hand matched again for accuracy and consistency where the ohms overlap over each other as if a single line (or it is rejected as a non match and becomes an orphan- sometimes we go through more than a few pairs to match with this scrurunity). Why do we match drivers so carefully? Absolute matched drivers are essential for perfect imaging and necessary to recreative a massive soundstage. Hand Matched drivers are also essential for a cohesive realistic organic sound. You can expect deep tight bass with no bloat yet at the same time the XTC is even and smooth through the mid range and treble. The XTC has precise timbre and has a knack of digging out sublime details with air as light as a feather; while remaining composed and never harsh or sibilant. Each song you play you will dive deeper into the recording.

Price Includes 3 different sets of ear pads to further enhance custom feel, comfort and tuning. Also included is a choice of wire type in a hand braided ofc litz 2m available in 3.5, 4.4 or XLR on the amp end. Get a second wire plus the ultimate in internal and external matched wiring - - we hand solder your XTC with internal 7N occ and WBT silver solder. This option also includes our own Copperhead Wire (the same wire we use to solder the drivers) in a 1.5m braided wire in your choice of trs 3.5mm or trrs 4.4mm on the amp end. The 7N OCC option gives you the ultimate matched wiring inside and out. We also include a practical reusable Waterproof Flight Case to protect these during transport and storage.

I chose the letters XTC to be many things; first off it is phonetic "X T C" - its also a double entendre (XTC like the drug ecstasy which gives users a euphoric rush and is a central nervous stimulant which causes high levels of dopamine to be released (a brain chemical associated with pleasure.).. or the word the actual word ecstasy, meaning rapture and immense pleasure. XTC can transport intense exaltation of mind and feelings- they suggest a state of trance or near immobility produced by an overpowering emotion - for music these headphones are like all of these things like a drug but none of the harmful side effects. What do I want from my XTC? Richer timbre, wider soundstage, a clean quiet power, somewhat neutral and truthful to the source, with very little coloration to the music. I want a very proper and wide soundstage, dimensionality, and specal presentation. Toe tapping, head bopping, dancing to the music good- you know... a good time like when I was a teenager. I want it to take me back to the best times in my life and make new memories of just how good a song I have heard over and over now makes me nearly weep with emotion. Is that all? Nope, I want the XTC to make me dream of it when I sleep, long to listen to when ever I have the free time. And the XTC should not waste any of that precious time with lackluster performance. The headphone should create emotion and admiration towards whatever genre of music I listen to with it. I want a party in my head. I want my third eye to nearly open as I transport mind, body and soul to a new plain of existence. I want goose bumps, I want my neck hairs to rise up and my head to tingle. I want to know with near certainty, this is probably as good as it gets - this could be my end game headphone and probably will be satisfying me for the very near and late future. I want to know this was an investment I take immense pleasure in owning. I want a headphone I can look at and admire it's construction and know the maker wasn't some assembly line worker. I have no time to wait around on junk or almost as good products. I want it all and I want it now...

JM Audio XTC 2.5 Euphoric Closed Black
Pros: Huge stage, Big bass with excellent texture, Outstanding detail, Nice air and sparkle up top, Build Quality Top of the line, aesthetically pleasing.
Cons: He continues to drain my wallet

John Massaria’s talent tuning headphones is no secret here at headfi. He continues to produce some of the best sounding headphones at any price. His latest closed back design, the XTC 2.5 has introduced to me to something I never thought I’d fall in love with…..a closed back headphone. Until I purchased the XTC 2.5 I hadn’t found a closed back that I kept for more than a week. I generally find that they sound artificial, very claustrophobic and severely lacking in the natural and gloriously huge sound of great open backs.

I have to admit that I had my doubts when John introduced me to this headphone. When it arrived I was excited but not looking forward to reporting what i thought was likely another letdown from a closed back. More on that later.

As many here know, ordering a headphone from JM Audio is quite a different experience from every other company out there. You have actual tuning options! And if the sound you want isn’t covered by JM’s extensive list of different tunings you just have a little chat with him and he’ll sculp the sound precisely as you’d like. I always choose ”Warm yet detailed” for my headphones and they’re always spot on for my preferences. I generally prefer the fuzzy pads but all the offerings are very high quality and comfortable. The golden cables are amazingly soft and supple.


When I first put my new XTC 2.5 in African Blackwood I was very pleased with the weight. These are not Titanic anchors like Audeze‘s offerings. They aren’t “light” but very comfortable and the weight is distributed very well. I can easily have a 2-3 hour session as they disappear on my head. The sound…..well they are unlike any other closed back headphone I’ve heard or owned. The stage is well outside my head with superb air and sparkle. Imaging is a blast….accurate and 3 dimensional. Vocals sound as if I’m middle stage 6 rows or so back. All instruments are where they should be. I get no feeling of confinement with XTC 2.5. They truly sound a lot like an open back headphone.

This brings me to bass. XTC 2.5 has some seriously well textured and DEEP junk in the trunk. Sub bass goes down..down…deep and LOW down on Béla Flec’s Flight of the Cosmic Hippo. This track will rattle your soul. Listening to it right now….hehehe.

Mid bass has terrific slam with no bloat and excellent texture. This headphone is a ton of fun folks. Mids are neither recessed or up front…just placed perfectly where they should be. Male and female vocals sound sweet and natural. Dave Matthews’ massive soulful high notes FEEL as if you’re there in Central Park in 2002. Adele’s ungodly alto vibrato is captured beautifully by XTC 2.5….abilities like these have always been specific to GREAT open back headphones for me. My partner is no longer forced to dig out her Beats ANC joints so she can hear her sitcom on tv. Sweet!


I find the XTC 2.5 an honest to goodness fabulous candidate for an all round everyday headphone. They’re very easy to drive and sound incredible on everything from my RME ADI 2 DAC fs to the Woo Audio WA7 gen 3 tube and heck, she even sounds darn good wit the Shanling UA5 dongle. I’d be remiss if I failed to mention what a revelation this headphone is with Woo’s new Mini Tube. Eye popping god tier stuff from those two. I’m addicted.

XTC 2.5 is by far my favorite closed back of all time and the proof is that it’s still sitting on my large noggin….with ZERO plans to move on.
