ALLEGRO II

The new flagship 2nd-generation in-ear monitor system for audiophiles and musicians with a universal fit. Completely redesigned from the ground up, the ALLEGRO II delivers even more masterful sound quality using the latest housing designs and driver technologies.

PERFECTED (NEW) TUNING

The Allegro II features a completely new quad-hybrid design (quad-brid), consisting of two 10-mm dynamic drivers, two bone-conduction drivers, eight balanced-armature drivers, and a single 6-mm planar magnetic driver.

Each frequency band has been carefully tuned for an unparalleled musical experience:

• Bass: The push-pull isobaric configuration of the two dynamic drivers with horizontal ventilation ensures lower background noise and reduced air resistance, enabling incredible punch and precise control.

• Bone Conduction: The bone-conduction drivers enhance sub-bass resonance and spatial perception.

• Mids & Highs: Eight balanced-armature drivers provide crystal-clear vocals and excellent instrument separation.

• Ultra-High-Frequency Range: A single 6-mm planar driver acts as a tweeter and delivers flawless highs with a smooth, natural frequency extension.

The sound profile is characterized by balance with outstanding qualities: powerful yet controlled bass, clear vocals, and smooth highs - a perfect all-rounder for every music genre.

PREMIUM CRAFTSMANSHIP

The newly designed housing not only improves fit and comfort compared with its predecessor, but also sets new standards in design and manufacturing: The use of additional 7-axis CNC and engraving machines enables one of the most complex in-ear housing designs ever created. Each component is finely polished, anodized, and then cryogenically treated to make the surface more resistant to scratches and help prevent damage from drops. With a dark bronze wave-pattern faceplate and a black housing, the design embodies elegance and understated restraint.

ADDITIONAL FEATURES

• Connectors: The ALLEGRO II is equipped with proprietary 0.78 mm 2-pin connectors made of rhodium-plated tellurium copper. This material combination offers the highest conductivity in the audio industry and far exceeds standard brass connectors.

• Internal wiring: For the first time, the ALLEGRO II uses two different internal cables: Copper XS and the new Silver XS. Each conductor is strategically assigned to a specific driver to optimize signal flow and transmit every frequency with exceptional detail.

• Cable: The ALLEGRO II comes with a specially tuned Copper+ cable. This in-house coaxial stranded cable (2-in-1) is surrounded by a proprietary double shielding with a semiconductor layer that completely isolates external electrical interference. It features an exclusive Y-splitter inspired by the housing design, matching rhodium-plated 2-pin connectors, and selectable connectors.

TEST REPORTS / REVIEWS

“The tuning of the Allegro II clearly builds on its predecessor and delivers a balanced sound signature with detailed tonality and natural presentation. While it continues to offer a balanced W-shaped sound profile, the tuning here - unlike the original Allegro - is more natural and coherent: All 13 drivers blend together in perfect harmony, from the deep, impactful bass through the natural mids to the clear, fatigue-free highs.”

After listening to it for a few days, you understand the intention behind it: It brings vocals and instruments closer to you and removes every obstacle between the listener and the music. You are connected to every detail, every bass note, and every cymbal strike. Anyone seeking this character, paired with fantastic craftsmanship and excellent presentation, will find a genuine experience in the Allegro II. The Allegro II goes straight onto our list of the best in-ear monitors!”
