How many drivers do earphones really need? I’ve heard models with as many as eight per ear. I’ve also heard excellent earphones that have just one driver per ear. With their HEM earphone models, Optoma NuForce lets you decide. You can get the single-driver HEM2s ($119 USD), the two-driver HEM4s ($299), the three-driver HEM6s ($399), or the four-driver HEM8s ($499). All share the same enclosure shape and features. When NuForce asked which I wanted to review, I opted for the top-of-the-line HEM8s.
