1MORE Triple Driver Over-Ear Headphones @ TechPowerUp
 

1MORE's newest full-size headphone offering is called the Triple Driver Over-Ear. As the name suggests, these headphones feature three drivers, although one is passive. 1MORE combined a relatively large dynamic driver with a graphene dome, ceramic tweeter, and a passive driver; all of this inside a closed-back over-ear design.
