Audio46's Opinion

You’ll hear some of the qualities that are present in the Momentum 4, such as the rich low-end and natural and doughy sounding presentation. But you’ll get a little less resolution, especially in the high frequencies. Still, there’s little to dislike about this crowd-pleasing sound signature. And when you combine the quality sound performance with a generous 50 hour battery life and customizable equalizer, the Accentum turns out to be a worthy purchase.
