Presenting
The new, 2nd generation flagship universal fitting in-ear monitor for audiophiles and musicians. Revamped inside and out, ALLEGRO II delivers a far more refined flagship sound quality utilizing the latest premium shell design and driver technologies.
Allegro II has an all-new quadruple hybrid (Quad-brid) design comprised of two 10mm dynamic drivers, two bone-conductor drivers, eight balanced armature drivers, and single 6mm planar magnetic driver.
Each frequency was carefully shaped for an unparalleled musical experience. The push-pull isobaric configuration from dual dynamic drivers with horizontal vent provides lower noise floor and air resistance allowing unbelievable impact and control. The bone conductor drivers enhances sub-bass resonance and spacial awareness. The mids and highs from eight balanced armatures provide the crisp vocals and instrument separation. The single 6mm planar magnetic serves as tweeters to deliver pristine treble with smooth, natural sound extension.
Characterized as balanced with standout qualities including powerful yet controlled low end, crisp vocals, and smooth highs. Serves as an all-rounded for any music genre.
The all-new shell design not only improves the fit and comfort over previous design, but pushes the envelope in design and manufacturing by incorporating additional 7-axis CNC and engraving machineries to produce one of the most complex designs made for earphones. Each part is finely polished then anodized followed by being cryogenically treated to strengthen surface scratching and preventing component damage from drops. With a dark bronze wave pattern faceplate and black modern pattern body, its color and design language provides an elegant yet understated feel.
ALLEGRO II comes with an in-house designed 0.78mm 2-pin connectors made out of tellurium copper with rhodium plating. The combination of these metals provide the most conductivity known in audio application that far exceeds standard brass connectors used on the market.
For the first time, two internal wires are used on ALLEGRO II: Copper XS and new Silver XS. Each wire is strategically dedicated to a specific driver intended to optimize signal flow and ensure every frequency is handled with extraordinary detail and clarity.
ALLEGRO II comes with a curated Copper+ cable for superior performance. This in-house designed cable consists of special 2-in-1 coaxial litz design encapsulated by a propriatary dual-shield + semi-conductive layer that will completely isolate outside electrical interference to maximize conductivity and performance. Features an all-new, exclusive y-splitter inspired by the earphone's intricate body design, matching rhodium plated 2-pin connectors, and your choice of our in-house designed termination.

"Allegro II tuning clearly follows its original predecessor, delivering a well-balanced sound signature with a detailed tonality and natural presentation of the sound. But while it still features a balanced W-shaped sound signature, unlike the original Allegro, the tuning here is more natural and coherent, as all 13 drivers blend In unison of a perfect harmony, extending from the deep, impactful lows to the more natural, detailed minds, and up to the clear, thorough, non-fatiguing highs."

"Overall, the PLUSSOUND Allegro II is an impressive upgrade on the original flagship and one that I would consider to be a musically enjoyable high-end performer. You could say the dopamine release is strong in this one."

"The textured sound, the intimacy and intensity are very special traits with this IEM, and when you listen to it for a couple of days, you get what the intention is. It brings the vocals and instruments closer to you, removing any obstacle between you and the music. You're connected to every detail, every bass note, and every cymbal hit. If you seek that kind of character, together with a fantastic build and design in excellent packaging, the Allegro II is one of those items that you can experience. The Allegro II joins our list of Best IEMs!"
