Audio-Technica ATH-E40 Professional In-Ear Monitor Headphones
The Audio-Technica ATH-E40 is a professional-grade in-ear monitor (IEM) designed for musicians, producers, and audio engineers who require precise monitoring on stage or in the studio. Featuring a unique proprietary dual phase push-pull driver design, these earphones deliver exceptional clarity and a balanced soundstage that excels at identifying nuances in a complex mix.
Key Features
- Dual Phase Push-Pull Drivers: Unlike standard single-driver IEMs, the ATH-E40 uses two drivers facing each other that move in opposite directions. This reduces harmonic distortion while providing high efficiency and improved timing across the frequency spectrum.
- Flexible Memory Cable: The 1.6m (5.2') cable features a loop-over-ear design with a memory wire that can be shaped to the contour of your ear, ensuring a secure, custom fit that stays in place during high-energy stage performances.
- Exceptional Isolation: The specially designed housings provide maximum passive noise isolation, allowing you to focus on your monitor mix even in loud environments without the need for high volume levels.
- A2DC Connectors: Equipped with Audio-Technica’s proprietary A2DC (Audio Designed Detachable Coaxial) connectors, offering superior durability and a secure connection while making the cable easily replaceable if damaged.
- Professional Accessory Kit: Includes a hard carrying case for protection, a 6.3 mm (1/4") plug adapter, and four sizes of silicone eartips (XS/S/M/L) to ensure the perfect seal for any user.

The Audio-Technica ATH-E40 is a standout choice for those who find standard IEMs too "bassy" or "muddy." Its focus on midrange accuracy and phase coherence makes it a reliable tool for vocalists and guitarists who need to hear their place in the mix with surgical precision.
