From Fosi Audio. Exceptional sub-bass extension and real impact with a controlled, energetic tuning. One of the most fun IEMs at this price — bass that hits hard and still stays focused. Best for bass-heavy music: EDM, pop, hip-hop. Action movies are visceral and impactful. Gaming is fun and immersive — built for enjoyment over precision.
