Its tuning angle and what the Geek team is going for is a higher end neutrally balanced sound. Or what they think is a higher end sound. This entails a whole lot of detail and technical prowess which the GK100 actually pulls off. For the most part it is closer to a neutral bright reference U tuning with a lot of aspects that are actually done well. I suppose I can say it is a unique tribrid formula with a unique detailed take on its balancing. The GK100 is tuned with a good 12dbs of pinna gain aka upper mids influence on its tuning which brings a cleaner vivid analytical sound profile.

The GK100 main tonal focus of the GK100 is all about highs, texture and details. It offer a treble centric W shape balance, which i’m not afraid to call vividly analytical. It’s bright, it’s energic, it have a thumpy bass with impressive speed and sub and mid bass layering, full yet understated mid range and speedy snappy highs with sharp note definition and x-ray like resolution.

The treble extension and energy on this unit is wild for its price. This is a semi-V-shaped IEM with a tilt towards higher frequencies.

To achieve a better balance, I feel that the treble needs to be toned down with physical EQ such as nozzle filters (Tanya filters recommended) and a warmer cable (a nice copper cable). I would not use foam tips with this IEM as you would be sacrificing too much soundstage expansion.

The 4 Piezo units are very sensitive and will not respond well when given too much power; it becomes harsh and less nuanced. At the same time, the 3DD units require some power at least. As a result of this, a medium amount of power will be the way to not agitate the Piezo drivers but also retain some grip on the dynamic drivers for a puncy bass experience. A strong Dongle from a laptop or Ipad is recommended.

To sum up, If you "put in the work" with this IEM, you will be rewarded with a very visceral experience.
