I’ve had the pleasure and privilege to have an extended demo of Vision Ears Phonix and EXT along the Australian Tour for a few weeks recently, herewith my impressions.
First of all, many thanks to Vision Ears and Minidisc Australia for providing the gear for the tour, and of course Aussie Head-Fi Legend
@Damz87 for running the tour!
I had the chance to demo both of these IEMs at Minidisc’s shop shortly after they launched in Australia, and my quick take at the time was that I was wowed by Phonix technical ability and tuning, and impressed with EXT midrange texture. So it was great to spend a few weeks with both of them to get to really know them better, and try them out with different sources and music.
Packaging, build, cables etc.
As I received these as part of a tour, I didn’t get the full unboxing experience, but you can check out photos etc. of that elsewhere. The IEMs themselves are each incredibly striking in their own distinct way, I think Vision Ears’ execution of their design is outstanding. The Phonix faceplate is a gorgeous combination of red & gold that has a glassy depth to it that catches the light in all kinds of beautiful ways, and I find blingy in a most elegant way. The EXT faceplates are made of machined aluminium finished in a royal purple, with a fine mesh underneath the faceplate that is meant to provide venting. These are both definitely the kind of physical objects that immediately grab your attention and demand you to investigate further.
I really like the case that Vision Ears includes for each of these IEMs, they are the best of any I’ve seen or used so far. The Phonix one is a clamshell style zip case made of very high-quality leather that meets the premium expectation you would have for an IEM at this price, while the EXT one is a hard metal screw case in the same striking purple finish as the IEMs themselves. Each case stores the IEMs and coiled stock cable no problem, and if you choose to use a chonky upgrade cable, that should fit easily as well. The stock cables are fine, although I find it odd that they are terminated with a 2.5mm balanced plug instead of the by-now-ubiquitous 4.4mm, or generic 3.5mm single-ended. You do get a 2.5mm-4.4mm adapter with each cable which I suspect 99% of buyers will use all of the time anyway, so why not just ship a 4.4mm cable with in the first place? That adapter just adds unnecessary bulk, and is something I know I’d be likely to lose.
Fit and ergonomics
I had no issues with fitment of EXT, although I’m aware some folks have a problem with the ‘bump’ on the back of the shell; but I actually really liked the deep, semi-custom fit. EXT nozzles are extremely wide, so I started off using Azla Sedna EarFit tips, which sounded great, but my ears got sore after an hour or so. I switched to a softer silicone wide bore tip, I think the ones that came with a Unique Melody IEM, and these were just about perfect.
Phonix fit is outstanding, I found them even more comfortable than EXT, and they are one of the most comfortable universals I’ve tried except maybe those from 64 Audio. However unlike most 64 Audio IEMs, Phonix is not vented at all, and I did notice pressure building gradually inside my ear canals which made me have to take a break. Not a significant issue really, but other manufacturers have better solutions for this to enable longer, fatigue-free listening sessions.
Both IEMs isolate fairly well, and despite EXT’s venting, I still thought it blocked outside noise about on par as most other IEMs I’ve used.
Sound Impressions
Once again, I think both of these IEMs are outstanding and mostly succeed at their
respective goals as stated by Vision Ears.
I found Phonix tuning to be pretty spot-on with my preferences, it’s elevated mid bass and lower mids produce a lovely warm sort of tone that I find really intoxicating. Some may prefer IEMs that produce a little more sub-bass, but to me Phonix pretty much nails the low end perfectly. Upper midrange drops slightly, but I really like the elevation around 2-4k that I think helps to produce quite a lot of the detail Phonix is so good at. My only occasional gripe is the peak at around 8k which I found just a little over done at times depending on the source recording and/or amp. Switching from the Jotunheim2 to the Vali2+ on my desktop, or from 4.4mm balanced to 3.5mm single-ended on the HiByRS6 fixed this with a small sacrifice to dynamics.
As far as technicalities go, Phonix is among the absolute best in the game, especially for those after top-tier resolution. Staging and instrument placement is great, with good width and depth, if lacking a bit in height; all of the instruments have plenty of room to breathe. I really marvelled at all of the detail I could hear when listening to Phonix, as I find this really enhances the engagement factor; being able to hear all of that detail with such incredible clarity, allows me to get right to the heart of how a piece of music was written, performed & recorded, and ultimately makes me feel that much closer to the artist who made it.
EXT goes for a very different kind of sound, employing 2x dynamic drivers for bass and midrange, and 4x Estats for treble, versus of the 13x balanced armatures used in Phonix. The tuning here is much more about low-end weight and power, which EXT has in spades, coupled with a forward upper midrange that is probably the best I’ve ever heard. Treble, however I found somewhat recessed, and is where I have most issues with EXT, as it really diminished my perception of details. This is probably the only real deal-breaker for me with EXT; when I’m listening to tracks I know well, and have heard specific details 1000s of times with other gear, it just evaporates with this IEM. I suppose if you are after a more ‘relaxed’ sort of listen, and are not fussed about listening right into the music, EXT works quite well; I did really enjoy it in those moments with bouncier music like rap, EDM, and some indie/alternative.
Source pairings
I spent a fair bit of time going back and forth between my various desktop sources and DAPs, which included my Schiit Bifrost2 DAC paired with either the Jotunheim2 or Vali2+ amps, my HiBy RS6, Astell & Kern SR25 mk1, and the Luxury Precision P6 Pro that I also had for a time as part of another tour. I had a fairly strong preference for the BF2/Jot2 most of the time with both IEMs, especially EXT. But there were a few other interesting synergies that I found as well, and I can appreciate that other folks may prefer a different type of DAC to the Bifrost2 or RS6 depending especially for a ‘cleaner’ or ‘drier’ sort of sound.
I found Phonix to be very easy to drive well with pretty much any source, even the Apple Dongle off my phone. And because of that 2.5mm stock cable, I figured I might as well take advantage it with the SR25 mk1 that has no 4.4mm anyways. Thinking I wouldn’t tax the SR25 with anything too demanding, I queued up Florist’s 2022 self titled album…
…and I was completely blown away, and spent the next hour of a lazy Sunday afternoon on my verandah totally lost in this gorgeous music. That album was recorded live on the front porch of a house in upstate New York, and I really did feel like I was transported 1000s of KMs away to be right there with the band as they were playing it. This is what Head-Fi is all about for me, these magical listening moments, and Phonix “goes to 11” when it comes to musical engagement.
With the other DAPs, I thought both the RS6 and P6 Pro R2R DACs worked great with the all-BA Phonix, although I did have a preference for the warmer and more immersive RS6. For the absolute ultimate in clarity and detail you may prefer the P6 Pro, but that DAP made me feel like I was looking
at an image of the music, whereas the RS6 puts me
IN the music.
Moving on the the EXT, I did try it with the SR25 with low expectations, and, well they were met at that low level. It just OK, but without enough juice to drive EXT’s DDs, the stage collapsed in height and depth for a rather underwhelming listen. Both the RS6 and P6 Pro corrected this and were quite a lot of fun. It was pretty hard for me to split these two DAPs, but I’d probably choose the P6 Pro for it’s it’s ability to tighten up the bass, and it’s slight improvement to detail retrieval vs the RS6. But it was the Bifrost2/Jotunheim2 desktop rig that really got the best out of EXT for me. The 6W into 32ohms available from the Jot2 really gets EXT’s DDs moving air nicely, with a huge improvement in stage depth and dynamics.
A few Comparisons
-Phonix vs Campfire Andromeda 2020. Maybe not a fair fight on the surface, as Phonix detail retrieval is definitely better, but Andro2020 is surprisingly not so far behind. Phonix timbre is where it really sets itself apart, I heard it to be much more natural than Andromeda, which sounds a bit glassy or ‘etched’ by comparison. Stage, and instrument placement/separation of them both are great, and I found both deliver a really immersive 3D experience, especially with the RS6 & Bifrost2/Jotenheim2. Tuning-wise Phonix sub-bass digs a bit deeper, but both IEMs have that forward midbass/ lower midrange that really works well for me. There’s no question Phonix is the better IEM, but this comparison shows just how well Andro2020 can punch above it’s weight.
-Phonix vs 64 Audio A12t. The first thing I notice between these two is the significant improvement in sub-bass extension A12t has and it’s much more polite treble. On the flip side, Phonix elevated treble pushes it ahead of A12t on detail retrieval, but the A12t is not all that far behind. A12t has Phonix covered for staging, it feels like it spreads out a bit larger, especially in height, and feels like a perfect sphere around my head with instruments and vocals positioned perfectly in space. It’s really hard to say which of these 2 is ‘better’, as they are more differences than similarities between them, and it’s more what specific tuning you like. I like both fwiw, and I find both of them highly engaging in different ways. On the ergonomic side of things, Phonix has no venting to relieve ear-canal pressure, and while it is fine for 90 minutes or so, I can listen to A12t or any other 64 Audio IEM that uses APEX modules for many long hours at a time.
-Phonix vs EXT. About the only reason I think you’d choose EXT is if you just really really need to have dynamic drivers handling the bass and midrange. EXT is more thumpy in the low end to be sure, but beyond than that I think Phonix is better in every other way, especially its treble, detail retrieval, and its deeper soundstage. “In spite of” being all-BA, I believe Phonix still has outstanding timbre by comparison to EXT, and it’s this type of comparison that shows just how good timbre can from an all-BA IEM. I kind of knew this already having owned A12t for about 12 months, but Phonix is likewise outstanding here.
-EXT vs Fir Xe6. EXT is totally outmatched in this comparison, especially in detail retrieval. When I A/B’ed from Xe6 to EXT it felt like all the life got sucked out of my music, and felt a bit like a TV going form 4k to 480p. Tuning-wise, you do get a sense of more sub-bass extension with EXT, but it’s the incredible midbass and lower midrange warmth of Xe6, it’s kinetic bass system, and the aforementioned detail retrieval that makes it a far more engaging listen to my ears. Yes, Xe6 is nearly $1k more expensive, but you get your money’s worth for the engagement factor imho.
-EXT vs Sony IER-Z1R. I’m going by memory of my now departed Z1R, but this is a matter of whether you want EXT’s forward midrange presence, vs the treble extension and better detail resolution of Z1R. Z1R midrange is fine, but EXT is ahead, especially for vocals I believe. They are both a lot of fun to listen to, and while both extend deep into sub-bass, Z1R pulls comfortably ahead, and has a much grander sense of sound stage as a result giving it that huge hall-like listening experience.
In conclusion, Phonix absolutely deserves a place at or near the very top of any shortlist of the absolute best IEMs on the market (it’s definitely on mine!!), especially if technical performance and detail retrieval are important. EXT is a bit harder to recommend I feel, as I think there are better choices at our around its price point, and even for less. It’s a little while since I’ve heard the FiR Kr5 or Ne4, but I have fond memories of them both, especially for that fun/engagement factor. And of course there is the venerable IER-Z1R.
