Final - Fusion-G

The Fusion G uses Final Audio’s unique triple hybrid structure that combines ultra-density foam, soft silicone, and high-elastic silicone into a single eartip design. Each material serves a specific purpose. The foam improves passive isolation, the soft silicone adapts naturally to the ear canal, and the high-elastic silicone core maintains structural stability while preserving acoustic consistency. Together, they create a fit that feels secure without introducing the excessive pressure commonly associated with traditional foam tips.

Most foam eartips achieve isolation by expanding aggressively inside the ear canal. Effective? Yes. Comfortable over long sessions? Not always. The Fusion G takes a different approach. Its ultra-density foam layer is thinner and designed to fit naturally without needing to be compressed before insertion. That means less inward pressure, faster insertion, and a more relaxed fit during extended listening sessions. The isolation is still excellent. External noise is reduced significantly, making the Fusion G especially useful for commuting, travel, or office listening. And when paired with earphones that feature ANC, the improved seal helps active noise cancelling perform even more effectively.

One of the biggest problems with many aftermarket eartips is how dramatically they alter an earphone’s tuning. Changes in ear canal volume, insertion depth, and nozzle interaction can easily shift tonal balance and staging. Final Audio has clearly paid attention to this. Because the Fusion G retains a shape closer to traditional silicone eartips, it minimises unwanted tonal changes while still improving seal and isolation. Your IEM keeps its intended character. Bass remains controlled, vocals stay natural, and the overall presentation feels consistent with the way the earphone was originally tuned. That balance matters more than most people realise.

The internal shaft of the Fusion G uses high-elastic silicone designed to resist collapsing even while adapting comfortably to different ear canal shapes. Combined with its wide opening design, the structure allows sound to travel more directly toward the eardrum with minimal obstruction. In practice, this helps preserve clarity and openness while maintaining a stable fit. Small details remain articulate, vocals retain focus, and the overall presentation feels clean and controlled rather than softened or congested.

Thanks to its compact short-shaft design, the Fusion G works comfortably with both wired IEMs and true wireless earphones. The shorter profile helps reduce fit issues commonly found with deeper foam tips, while also making insertion feel quicker and more natural across a wider range of earphone designs. It’s the kind of flexibility that makes these easy to recommend regardless of your setup.

Final Audio keeps the Fusion G surprisingly practical despite its specialised hybrid design. Adjacent sizes alternate between dark and light grey shaft colours, making size identification much easier during daily use or tip swapping. The Fusion G is also designed to be inserted naturally without compressing the foam beforehand, allowing the ultra-density foam to adapt smoothly inside the ear canal with less pressure and a more consistent seal. They recommends experimenting with different sizes, including different sizes for each ear if needed, since ear canal shapes often vary between the left and right side. Getting the right fit can significantly improve isolation, bass response, and overall tonal balance. Sometimes, the right eartip fit changes the entire listening experience.

Because the Fusion G uses specialised foam materials, proper care is important. Final Audio recommends cleaning the tips gently using a dry cloth rather than water or wet wipes, as exposure to liquids or alcohol may accelerate material degradation. The Fusion G is considered a consumable accessory, with recommended replacement around every three months depending on usage conditions. Temperature can also affect the foam behaviour slightly. Colder environments may temporarily stiffen the material, while warmer conditions may slow restoration speed after compression. Handled properly, though, the Fusion G remains one of the more thoughtfully engineered hybrid eartip designs available today.
