The Tanchjim Fission is a wired in-ear headphone featuring a dual-chamber dynamic driver with inner and outer double-magnetic circuit technology, offering low distortion and a wide frequency response.
The HearWiki takeAI-condensed
The Tanchjim FISSION is a wired in-ear monitor that pairs two dynamic drivers in a dual-chamber design, using an inner and outer double-magnetic circuit to keep distortion low. It delivers a broad frequency range from 8 Hz to 48 kHz, making it a solid choice for detail-focused listening without active noise cancellation.
What works
- Dual dynamic drivers with dual-chamber design for balanced sound
- Wide frequency response extends from 8 Hz to 48 kHz
- Low distortion thanks to double-magnetic circuit technology
- Standard 2-pin 0.78 mm connector for easy cable swapping
- Lightweight and comfortable for extended sessions
What doesn't
- No active noise cancellation, so external noise may intrude
- Requires a wired source, which may not suit all users
- 16-ohm impedance may need a decent source for optimal volume
- Price point might be high for entry-level listeners
