The AC45 redefines the acoustic potential of clip-on open-back headphones. Its large W-shaped biofiber composite diaphragm, independent linear surround system, and high-dynamic symmetric driver work in perfect synergy, overcoming the typical limitations of clip-on headphones in the mid and low frequencies. Despite its compact, open design, the AC45 delivers a balanced sound signature with impressive dynamics.

Independent Linear Surround System

Specifically tuned for open-back clip-on headphones, it strengthens mid-bass presence and ensures the low end remains solid and never hollow, even in an open soundstage.

High-Dynamic Symmetric Driver

Delivers ample power and maintains stable, detailed reproduction even in complex passages. Every impact is precise, every nuance clear.

Open-Back Clip-On Design

Allows natural sound diffusion, creating a spacious, immersive soundstage with realistic imaging. Compared to in-ear or closed-back headphones, the AC45 offers superior transparency, airiness, and live-like authenticity.

Semi-Memory Aluminum Ear Hook

Comfortable and secure, even during extended listening sessions. Optimized curvature and pressure distribution ensure a precise fit for different ear shapes.

High-Quality Cable with Interchangeable Plug

Oxygen-free copper Litz cable guarantees clean signal transmission. Modular plug allows easy switching between 3.5 mm single-ended and 4.4 mm balanced connections, ensuring durability and broad device compatibility.

Sound Tuning

Authentic, natural, and musical – warm, vibrant sound that preserves the texture and essence of music across vocals, pop, light music, and acoustic performances.
