Fosi Audio i5 Planar Magnetic Headphones are Coming!

[Fosi Audio]

The i5 was born from our mission to make planar magnetic headphones more accessible, without compromising on sound quality, comfort, or design. Over a year of in-house development and acoustic tuning led to a headphone that delivers exceptional clarity, low distortion, and lifelike detail.

Immersive Listening | Pure Original Sound​

Crafted with an ultra-thin diaphragm using nano-level technology, an invisible high-powered magnetic system, and precision acoustic design, the i5 delivers high resolution and low distortion for a truly lifelike listening experience.

Ultra-Large Diaphragm | 97mm Ultra-Large Diaphragm​

The ultra-thin diaphragm, crafted with nano-level precision, delivers faster response, enhanced detail, and a more natural, clear, and layered sound.

Ergonomic Design | Long-Lasting Comfort​

Designed to follow the natural contours of the head, the i5 ensures a secure yet gentle fit. Even during extended listening sessions, it remains comfortable and pressure-free, letting you enjoy your music without distraction.

Refined Craftsmanship | Where Aesthetics Meet Quality​

A refined fusion of premium materials and elegant design, delivering a look that exudes sophistication, texture, and distinctive character.

price range?

Glossy says $5XX. Only thing missing from the ad is 'stealth' magnets.

Diaphragm is 2 microns but also “nano level”?

Yes, 2000nm.

Just home from Axpona. Was told the price is $550. Unfortunately, it was impossible to demo them. I tried on two separate occasions, but they had their speakers (they sound good) blasting the entire day in a small hotel room. So couldn't really make anything of the headphones.

Hifiman, this is how a headphone is made!!

This is some good marketing. Love the hype. If there was a pre order button….

I just bought the Nano, if I knew I would have waited. This looks very interesting. Eagerly wait for first impressions. Good job Fosi, from strength to strength.

Got a chance to try it at Axpona at Zeos booth within the Eargear room. Needless to say - very loud room - open back - from sub- bass to midrange was good with a detailed upper frequency tuning, but not in a harsh sibilant way. Was being sourced from Z’s Orchard amp collab, don’t recall the preamp or DAC. Build was solid and the comfort was outstanding.
