Mods, Could we move this to the iem thread?
I’m getting one for review and am pretty excited about it. I love the idea of budget iems that use nice drivers, and rumour is this uses the Origin driver (260 dollars) so I find this an excellent value, or at least potientially to be.

The Story Behind “FISSION”
FISSION — Sound That Adapts to You
FISSION isn’t about you adjusting to your gear — it’s about your gear flexing for you.
Swap out three different nozzles — brass, titanium, stainless steel — like changing loadouts, each giving you a whole new sound flavor.
Then dial in one of four analog filter settings, like building your own audio skill tree.
12 sound combos in one pair of IEMs? That’s peak customization.
And we’re not stopping there.
Three swappable connectors mean you can go from gaming to commuting to content creation without switching devices. One setup, all your worlds.
Plus, our ASANO TANCH just dropped a whole new cutie mood pack series— 20+ adorable new expressions, because your sound deserves a personality, too.
When the sound starts to split, your different sides come alive.
So, who do you feel like listening to today?

Product Highlights
Self-Developed DMT 5thGen Driver
Inherited from our flagship ORIGIN IEM, the all-new fifth-generation DMT driver features a self-developed dual-magnet, dual-chamber architecture. Engineered for excellence, it delivers the highest magnetic flux, lowest distortion, most powerful dynamics, and peak efficiency ever achieved in a TANCHJIM driver. Compared to the previous DMT 4, it brings a significant leap in overall performance—offering more lifelike sound and a dramatically expanded soundstage.
4 Tuning Profiles
Featuring a patented 4-step adjustable analog filter system, users can switch between different filter modes using a rotary knob to enjoy a variety of listening experiences.
3 Material Nozzles, 3 Sound Modes
Featuring a swappable nozzle design, the S-Standard, D-Dynamic, and L-Light modes use brass, stainless steel, and titanium materials respectively—each offering distinct resonance characteristics. Paired with the 4-step adjustable filter switch, you can easily explore up to 12 unique sound profiles from a single IEM, delivering exceptional versatility and fun.
