Comment: Rabbit cute I guess. Mild V-shape tuning, with decent technical performance Sounds too generic, note weight isn't well defined
Symphonium Helios SE Reviews
Symphonium Helios SE reviewed by: Jays Audio
Best Treble around it's price. Super airy but still smooth. Bass-scoop isn't as bad as I thought, but those who want mid-bass - avoid it. Jays Audio Youtube Channel
Symphonium Helios SE reviewed by: Precogvision
See Helios but with more mid-treble and mid-bass. Precogvision Youtube Channel
Symphonium Helios SE reviewed by: Nymz
Limited to 50 units. A huge improvement fit wise versus the original. Great TOTL all-rounder. Great sub, upper mids and treble. Mid-bass is an improvement but still not boosted. Great technical chops while fixing the sense of plasticness the original had.
