The Verdict

These are very fine headphones, capable of producing truly wonderful listening experiences. They are bold and, at times, an emotional specialist: magical in their lane, solid elsewhere, physically demanding. They work best with electronic, rock and gritty vocals on tubes. At around €3,000 they combine a hefty price with a hefty feel, but deliver a strong experience at that point. If you don’t already own a premium planar and are shopping in this bracket, they are absolutely worth an audition. For me they make more sense as a spectacular second‑system headphone than as an only pair; if comfort isn’t a deal‑breaker and you like this tonal profile, they become very tempting – especially at roughly half the price of a Hifiman Susvara.

Context

Legend has it that in the strait between Sicily and mainland Italy there lurked two horrendous subterranean creatures: Scylla and Charybdis. Odysseus, being Odysseus - tough guy, adventurer and all round legend - sailed straight through this deadly bottleneck on his long and troublesome journey.

It appears the Blazman (Blaz Erzetich) grabs these names for headphones and their preferred amps, to hint at immense power and awe-on-tap, the tightrope walk between two sonic “beasts,” delivered in his Charybdis/Scylla set up.

The nod to Odysseus’ own success in getting through unscathed is a myth‑flavoured metaphor for Blazman’s deft navigation of massive planars; and while I don’t have the Scylla head amp, I do have a fantastic Cayin HA‑2A.

The following review is an experience‑led exploration of Erzetich’s super‑premium planar headphone; if you’re building a serious system and either haven’t tried big planars yet or are actively shopping them, this one belongs on the list

Listening Journey

Starting out with connecting the Charybdis to my Naim Uniti Atom HE directly (XLR) I then moved to an RCA connected head amp in the Cayin HA2A, keeping the Naim on DAC duties. Finally, I put in a pair of grounded XLRs, the balanced connection from Naim to Cayin worked best.

Electronic and rock quickly exposed the basic character. Magic Sword and Deadmau5 showed off “smart” bass – lively but not doof‑doof – and a knack for crunch and snap without flab. AC/DC and 80s rock landed firmly in the Charybdis swim lane for me: this thing loves distortion, guitars, and male voices, turning everything into a vivid, slightly over‑saturated close‑up. In time I started to hear a faint extra warmth or fuzz around rock guitars, as if the existing distortion had been enriched or spotlit. It worked: rock sounded terrific, but the same treble energy that made riffs exciting also brought in top‑end fatigue on “Hells Bells” and the more intense Shane Smith vocals.

The turning point was going fully balanced into the Cayin. Switching to XLR felt like the system “popped into gear.” Imaging and staging snapped into focus, the overall balance improved, and the sound gained a sense of ease and authority. AC/DC’s “Dirty Deeds Done Dirt Cheap” shifted from impressive to properly musical; instead of analysing, I just found myself enjoying it. Going back to Geronimo, I heard more space, breath and air than before, with instruments and voices articulated clearly and the depth of character in the vocals really standing out. Deadmau5’s Where’s the Drop? became a showpiece: crisp, exact bass laying the foundation for his signature ethereal elements, which floated above and around the mix to create a convincingly 3D, immersive bubble.

 

Through all of this, texture, detail, weight and brightness never really left the picture. I kept coming back to how heavy the headphone is and how forward the presentation feels. With the right material – Deadmau5, Magic Sword, AC/DC, High on Fire, Captain Beefheart – that forwardness reads as energy and excitement. With Home Free’s massed voices, some of the more delicate Fink material, or just longer sessions, it crosses the line into “too much,” with some vocals sounding forced and treble leaning into my ears rather than inviting me in. The Fink test summed it up neatly for me: Where the Focal Utopia OG sounds clean, spacious, authentic and articulate; Charybdis sounds bold, rich and textured and heavy, too forward, blunting some of the songs’ gentleness.

 

Experience Map

Tone Colour

Charybdis is rich and saturated; magical on grainy male vocals, too much for gentler fare

Charybdis is more cask‑strength single malt than table wine: dense, saturated and absolutely brilliant if you’re into grainy male vocals and guitars. Samuel T Herring, Shane Smith, Beefheart – all pick up that woody, lived‑in glow that makes you want another pour and pulls you deeper into the glass. When I move to gentler fare, though, the same richness plus a forward top end can feel like it’s drowning out the quiet parts, stepping in front of singers like Fink and “helping” a bit too much - some of the original, understated character gets smeared or stylised, so it feels a bit less authentic and more “processed” or hyped than you know it should.

Texture Detail

Outstanding at exposing grit, rasp and micro‑detail, never overdone

If you’re into vocal cords: these things hand them to you on a plate. Beefheart turns from singer into exposed larynx study; grit, rasp, squeaks, it’s all there, in hi‑def. Guitars arrive clean and chiselled, finger clicks are unnervingly on‑point, and Deadmau5 plus Magic Sword get the full immersive treatment: crisp bass, proper crunch, stacked textures you can fall into.

Dynamics Jump

Big, eager dynamics that make rock and metal thrilling, but can edge into “too much” on already hot passages

In its natural habitat – rock and metal – Charybdis doesn’t so much play as pounce. AC/DC, High on Fire, 80s rock: drums snap, riffs bite, everything comes at you with that “let’s go!” energy. Push it with already hot recordings, though, and the line between “hell yes” and “please calm down” gets thin; the same jump factor that thrills can tip over into a bit bitey.

Space & Imaging

Wide, airy stage with strong layering and a holographic feel on the right tracks

Stage and imaging are where Charybdis starts to feel a bit mythological. On “The Wreck of the Edmund Fitzgerald” you get real air, depth and a convincing sense of ocean, and over the Cayin/XLR chain Deadmau5 turns into a transformative experience: ethereal bits float above and around, bass lives down below, and it’s easy to point to who’s doing what and where. More than once you end up looking around the room to find the source of little details that suddenly seem to be out in the space with you.

Timing & Flow

Locks in solidly for rock and electronic

On rock, metal and electronic, the timing is happily in the pocket: drums are quick off the mark, riffs lock, beats get you starting to move. Swap to Utopia on Unkle or Kidjo, though, and you notice that while Charybdis brings out some movement, the Utopia brings you rapidly to a flow state; you get easy, slipping into the natural groove of the music that makes your foot tap without asking permission and you forget time, minutes hours, that sort of thing.

Comfort & Fatigue

Sonically engaging but physically demanding; weight and forwardness catch up after 30 minutes or so.

Physically, this is not so much a headphone as a lifestyle choice. It’s big enough that after a while you edge toward “headache territory.” Sonically, the forward upper registers don’t exactly help you unwind; compared with Utopia and Diana V2, Charybdis is the friend who’s great fun at the pub and a terrible idea for a quiet night in. You never forget you’re wearing it – or that it’s in charge. My memory of the equally large Abyss 1266 was awkward to handle but you could wear it for hours. I’d trade that awkwardness for comfort any day. This is the biggest criticism I have of these headphones.

Emotional Engagement

A brash emotional specialist that’s breathtaking in its lane and very good when the music steps outside it.

When you keep it in its lane, Charybdis is glorious: it slings you back into live gigs, turns Beefheart into a force of nature, and makes Deadmau5 feel like you’re standing in the middle of some gleefully over‑funded light installation. Step outside that lane, into orchestral or tender singer‑songwriter territory, and the magic fades; things go muted, unemotional, no longer ethereal. It’s a big, bold, brash emotional specialist – breathtaking when the stars align, and a bit much when they don’t.
