Good for the price
They’re tiny budget monitors, yeah they don’t sound perfect, yeah they struggle from their very limited size, but for the price they’re best you can get really. Could never mix on these, too harsh and limited by the 3.5 inch woofer, but they’re nice to just have the option of not using headphones if say you’re someone who practices with a guitar plugin or etc.
