Overview

 

When the goal is to replicate the sound quality of reference-class, multi-drivers high-end speakers in your ear, the Optoma NuForce Primo 8 earphone stands well apart from the crowd. To achieve this elusive goal of breathtaking realism, explosive dynamic, and natural sound, the Primo 8 embraces patent-pending technology to capture the best of both worlds: the coherence and seamlessness of a one driver earphone, with the detail and tran-sient speed of a balanced armature speaker array.

Balanced Armature Drivers

Four balanced-armature drivers in each earphone deliver a smooth, extended response, explosive dynamic realism and fatigue-free sound.
  • +Balanced armature drivers deliver the highest eiciency of any in-ear speaker design available.
  • +3-way design with two units operate as one for bass frequencies and one speaker each for midrange and treble bands.
  • +With two bass speakers working in tandem, the listener experiences the purest, most natural bass possible.
  • +Primo 8 is far more reined and coherent than any other balanced armature earphones. Its remarkable midrange resolution, clarity and neutrality are among its most distinctive features.

NuForce Linear-Phase Crossover Network

+ Utilizes a proprietary first-order Butterworth filter crossover network to make the earphone’s four speakers truly sing as one.
+ Primo 8’s four-driver speaker array employs a crossover network design that seamlessly distributes the music’s frequency bands.
A three-way phase-coherent crossover design achieves near perfect linear phase performance resulting in a natural, fully dimensional soundstage, lightning-fast transients and crystalline transparency.

Proprietary Cable Design

+ Utilizes a proprietary two layers of star-pattern wires (Kevlar Silk, silver and OFC copper wires) with groundbreaking technologies to achieve incredibly accurate sound reproduction.
+ Isolated left and right ground wiring reduces interchannel crosstalk while maximizing channel separation.

Reviews

Media(8)
The NuForce Primo 8 earphones are an excellent performer and an easy recommendation to make for an audiophile on the go. They have a superb balanced and neutral sound signature that is suitable for a wide variety of music. "
“Everything is harmoniously balanced, the bass is well boosted but without saturation, the medium that binds to the bass perfectly, the acute is present but without overdoing it and to finish, a surprising stereo” "
“The bass strikes a perfect balance between power and precision; the mids sound incredibly clear and natural; and the highs help these headphones reveal subtleties of ambience and space that even many of the best loudspeakers might mask.” "
"Awarded 5 stars by the UK national newspaper – The Daily Mirror: “Once snug, the Primo8’s performance was indeed revelatory, delivering a range of wide detail rarely experienced with any sort of earphones, let alone in-ears.” "
"The Primo 8 is quite simply a world-class universal-fit earphone – one that can equal or surpass the performance of models costing considerably more.“ "

“The Primo8 have a good level of performance with a neutral tonal balance, good power handling, high bandwidth and detailed and transparent listening.” "
“The result: a general equilibrium quite impressive, serious crazy, a medium that is not an acute and that is not too much, and above all, a dynamic and truly amazing stereo.“ "
