Equalizers
Equalizers truly are a marvel, offering a solution for those of us who can't afford expensive headphones. Given that each headphone brand has its unique sound signature, I found myself purchasing various headphones for different scenarios. This led to frequent frustration due to the disparities in sound quality and manufacturer-specific tuning. Equalizers have played a pivotal role in standardizing these differences to some extent.
