Massdrop Blue Box: NuForce HEM IEMs
Massdrop Blue Box: NuForce HEM IEMs

NuForce HEM Blue Box

Announced at the Consumer Electronics Show in 2016, Optoma NuForce’s HEM line features the latest balanced armature driver technology, custom-designed linear-phase crossovers, and the excellent sound quality we’ve come to expect from the company. Inside the acoustically calculated, vibration-free Lexan earpiece, each in-ear monitor has a different number of drivers that increases with the model number: the HEM Dynamic uses one balanced dynamic micro driver per side, the HEM1 uses one Knowles balanced armature driver per side, the HEM4 has two Knowles BA drivers per side, and the HEM6 has three.
