Products like the Monolith M300 in-ear earphones show how different Monoprice is from other audio brands. Other than their name and logo, Monoprice makes no pretense of brand identity in their products. Their focus is working with various overseas manufacturers to deliver products of (usually) reasonably good quality in all sorts of categories, at prices so low that few other companies can match them. However, the Monolith M300 earphones reflect what seems to be a minor sideline for Monoprice: products that look like knockoffs of well-regarded models made by other companies.
