Frequently Asked Questions

Q: What cable connectors does the TANCHJIM Fission come with?

A: The Fission uses a 0.78 mm detachable cable system and supports three interchangeable termination plugs: 3.5 mm single-ended, 4.4 mm balanced, and USB-C (Type-C). This makes it compatible with a wide range of source devices including smartphones, DAPs, and balanced amplifiers.

Q: What are the 4 sound modes and 12 sound profiles?

A: TANCHJIM engineered the Fission with a physical tuning system that lets you switch between 4 distinct sonic characters — each with multiple sub-profiles — covering a broad range of sound signatures from warmer, bass-forward tunings to brighter, more analytical ones. This allows you to fine-tune the sound to perfectly match your music genre or personal preference without any software.

Q: Is the TANCHJIM Fission easy to drive from a smartphone?

A: Yes. With an impedance of only 16Ω and a high sensitivity rating of 126 dB/RMS, the Fission can be driven efficiently by smartphones, laptops, and portable players. For the best performance — especially on the 4.4 mm balanced connection — pairing with a dedicated DAC/amp is recommended.

Q: What is DMT5 technology?

A: DMT5 (5th-Generation Dynamic Magnetic Technology) is TANCHJIM's proprietary driver design featuring an internal and external dual magnetic circuit combined with a dual-cavity dynamic coil. This architecture produces superior magnetic flux, tighter control over the composite diaphragm, and extremely low total harmonic distortion (0.056% @ 1 kHz).
