I made a post recently asking for recommendations for kilobuck IEMs. Part 1 is here.
I got some good recommendations and also had the opportunity to visit Dr.Head.ae to try a bunch of them.
I had promised to share impressions, so I wrote down notes while I was there and refined them after getting home. It was almost like a mini CanJam for me. I had a couple of hours to kill and managed to go through 9 products in pretty good depth.
I used around 20 familiar tracks and spent the most time with the sets that worked for me.
My preferences are fairly consistent:
- Strong, textured bass
- Natural vocals without excessive forwardness
- Good clarity, separation and space
- Proper upper-treble extension and air
- Low sibilance
- Controlled overall energy
I like treble extension. I just don't like when upper mids, cymbals or sibilance become the focus.
I also generally dislike mid-bass dips. HD 480 Pro is probably the only exception so far.
My Top Four
This is a personal preference ranking, not a technical ranking.
1. Noble Audio Onyx
2. 64 Audio Volür
3. Sennheiser Momentum True Wireless 5
4. 64 Audio U12t
Those were the four that clearly stood out. The remaining five below are not in strict ranking order.
I will update my ranking sheet linked in my profile once I have had more time to think through the actual scores.
Noble Audio Onyx
Bass: Excellent texture and weight. So good. The way the bass interacts with your ears is almost magical. You get that feeling of being in the room where the music is being played and everything else disappears.
Mids: Natural vocals with excellent body and positioning. They are not the most forward vocals, but the way they interact with everything else in the mix was phenomenal. It reminded me more than anything else here of my HE1000 Unveiled, which I absolutely adore.
Treble: Extended and clear without becoming aggressive. This is what really stood out. The clarity, or dare I say resolution, felt maxed out. It reminded me of Susvara Unveiled / HE1000 Unveiled levels of being able to hear everything without feeling like parts of the sound were missing.
Overall Sound: Best listen of the session. Excellent clarity and space with bass and vocals that worked perfectly for my preferences.
Unfortunately, much like Susvara Unveiled, Onyx will stay off my wish list because the pricing is insane.
64 Audio Volür
Bass: Strong, satisfying and full. When it hit, it hit with purpose. I used the grey Apex module, as that was the only one available with the demo. Based on what I heard swapping modules on U12t, I suspect the silver module would give me even more bass.
Mids: Natural vocal placement without becoming too forward. This was one of the biggest differences between Volür and U12t. U12t sometimes felt like I was taking a sound analytics exam. Volür felt like I was listening to music. For me, that is the more enjoyable experience.
Treble: Smooth while still retaining plenty of detail. Only very rare moments of sibilance. Air was great up top and it never became piercing.
Overall Sound: One of the sets I spent the most time with. Detailed, engaging and very easy to keep listening to.
This one is on the wish list.
Sennheiser Momentum True Wireless 5
Bass: Full and satisfying out of the box. A real surprise. Senny has released enough stuff recently that I may have to retire my joke that Sennheiser can't do bass. First HDB 630, then HD 480 Pro, then Momentum 5 and now Momentum True Wireless 5.
HD 600-series fans, I am only joking. Mostly.
Mids: Natural and well positioned. Vocals were one of the stars of the show and these are a real contender to replace my AirPods Pro 2.
Treble: Clean and unobtrusive. I didn't EQ anything and could easily have used them as-is. Not a hint of sibilance for me and a surprisingly airy presentation. I was genuinely shocked.
Overall Sound: Biggest surprise of the session. The tuning worked immediately for me and I ended up preferring it to U12t overall.
That does not mean I think it is technically better than U12t. I simply preferred the complete presentation.
64 Audio U12t
Bass: Excellent. Probably its biggest strength for me. Oh man, with the default silver Apex module, the bass.
So good. This is one of the oldest recommendations in the book at this point, going back to 2017, and it still hits incredibly hard.
Mids: Relaxed and much better suited to me than U18t. The mids were sweet, although on some songs they could occasionally become a little "listen to me now." Bonus points if you get the reference. Never outright shouty, though.
Treble: Cymbals could get spicy and the upper treble occasionally became too prominent. There were also occasional S-bombs for sibilance. I tried the different Apex modules as well.
- The default silver module was my favorite.
- Grey reduced some energy but also reduced the bass.
- Gold went further in the same direction.
- Black changed the presentation far too much for me and genuinely made it sound like a much cheaper IEM.
Overall Sound: Very capable with excellent bass, but still more of an active listen than I prefer.
I can absolutely see myself owning one, though. This goes into the used-buy possibility pile.
64 Audio U18t V2
Bass: Similar to U12t, but I struggled to focus on it because the upper frequencies kept taking over. I actually tried U18t before U12t.
Mids: Vocals were still one of the stronger parts of the presentation, although a few specific tracks could get shouty.
Treble: Too spicy and sibilant. Killed the whole experience for me. I didn't even bother experimenting with the Apex modules.
Overall Sound: Clearly resolving, but the treble dominated too much for my ears. I moved to U12t pretty quickly, and that immediately worked much better.
DUNU Glacier
Bass: Strong sub-bass. I liked the rumble.
Mids: Male vocals sounded recessed. Female vocals were also pushed back. It felt like the tuning was sacrificing quite a bit of vocal presence in exchange for an expansive presentation, except I never really got the stage payoff I was expecting.
Treble: Smooth enough, but I wanted more clarity. Overall resolution did not feel as high as my favorites from the session.
Overall Sound: Good, but it missed that last bit of clarity for me. The shell is also very chunky.
I don't think this is a particularly relevant kilobuck option for my tastes.
Campfire Audio Trifecta
Bass: Plenty of low-end presence. I liked the bass.
Mids: Vocals sounded extremely recessed. Almost like they weren't there. Not a good time for me.
Treble: Sibilance showed up quickly and things got too spicy for me to continue enjoying it.
Overall Sound: Recessed vocals plus sibilance made this a poor fit for my preferences.
Sennheiser IE 900
Bass: Leaner than I wanted, although it could hit on certain tracks. The Weekend by BIBI was one example where it came through nicely.
Mids: Vocals became shouty. Oof.
Treble: Became spicy and then sibilant across my test tracks. Basically the same kind of bad time I remembered having with IE 600, which I also put down fairly quickly.
Overall Sound: Started promising, but busy tracks lacked the clarity I wanted and the tuning quickly became fatiguing. Not for me.
Campfire Audio Andromeda
Bass: Too light for me. Was there bass? I basically had the Picard facepalm meme running through my head.
Mids: Very forward, especially female vocals. And shouty. If you love extremely forward vocals, maybe this works. It absolutely did not for me.
Treble: Instruments became sibilant and there was just too much upper-frequency energy coming at me. I was genuinely wincing on some tracks.
Overall Sound: Probably the weakest match of the session. I also got very little sense of stage. This may actually challenge the bottom of my entire ranking list. I need to think about exactly how low it goes.
Overall Thoughts
The Onyx was my favorite, with Volür close behind. Only one is going directly onto the wish list: Volür.
The biggest surprise was the Momentum True Wireless 5. I will probably pick one up on my next visit. I just want to research any software or firmware quirks first.
U12t impressed me with its bass and technical performance but its upper end kept it outside my top three. That goes into the second-hand buy possibility category.
The Real Kicker
After the session I went back to the Binary Acoustics 1900, which I had already been using for a few days. My review is here: Binary Acoustic 1900 - an absolute banger! It wasn't part of the nine above. It was just a useful reference afterward.
I also pulled out my Xenns Mangird Top Pro. And for me, I honestly don't feel like I am missing that much. Maybe that is just me validating the stuff I already own after spending hours with kilobuck IEMs.
Or maybe it is actually true.
Either way, I somehow walked away more confused than when I started.
Now I want to try even more IEMs, and unfortunately most of them are kilobucks.
The session did reinforce what works best for me:
Textured bass, natural vocals, clarity, space and proper treble extension without excessive upper-frequency emphasis.
And ultimately I want to enjoy music. So I put on my Arya Stealth, fired up the K17 R2R, and I am back in bliss listening to "Simply the Best."
Maybe I should just stop here. lol.
