Allow Synth for Sale to introduce you to this ACS Eclipse 500 Hybrid Universal In Ear Monitors
The ACS Eclipse 500 is a premium in ear monitor system engineered for musicians, audio professionals and discerning listeners who demand exceptional sound and long wearing comfort. Built in the UK, it combines an 8mm dynamic driver for deep, controlled bass with dual balanced armature drivers for articulate mids and a super tweeter for detailed highs. These drivers are precisely aligned via a passive three way crossover, resulting in an expansive and well defined soundstage across all frequencies.
Designed for comfort as much as clarity, the Eclipse 500 incorporates ACS’s unique 17dB passive ambient filter. This allows natural airflow through the ear canal, reducing the sensation of pressure often experienced with traditional in ear monitors. This innovation enhances both the listening experience and long term wearability, whether on stage or in the studio.
Robust yet refined, the Eclipse 500 features lightweight die cast aluminium housings with interchangeable faceplates and stainless steel nozzles in various lengths for a tailored fit. With a silver plated oxygen free copper cable and replaceable two pin connectors, this monitor is built for both sonic performance and durability.
Key Features
- Hybrid driver system for full spectrum clarity:
The combination of dynamic and balanced armature drivers with a super tweeter delivers detail, warmth and sparkle across a wide frequency range. - ACS ambient filter technology:
Integrated 17dB passive isolation allows airflow for improved comfort, reducing ear fatigue during long sessions while maintaining external noise attenuation. - Custom fit and modular design:
Stainless steel interchangeable nozzles, foam tips in three sizes, and optional custom sleeves allow for a tailored fit and acoustic preference.
Immersive sound with accurate separation:
The Eclipse 500’s hybrid driver configuration offers a finely tuned listening experience. An 8mm dynamic driver handles low frequencies, providing punch and warmth without overwhelming the sound. Mid and high frequencies are managed by dual Knowles balanced armatures, preserving detail and clarity in vocals and instruments. A dedicated super tweeter ensures shimmering highs with a Hi Res Audio certified frequency response up to 24kHz. All drivers are aligned via a passive three way crossover to eliminate distortion or overlap, giving every element space to breathe within the soundstage.
Natural comfort with passive isolation:
Where most in ear monitors create a full seal and can feel pressurised over time, the Eclipse 500 uses ACS’s proprietary ambient filter to allow airflow. This 17dB passive isolation reduces the feeling of blockage in the ears while maintaining effective external noise attenuation. This makes long listening or performing sessions more comfortable and less fatiguing. The result is a more natural, open sound that preserves clarity without causing discomfort or distraction during use.
Built to perform, styled to suit:
Each pair of Eclipse 500 monitors is manufactured in the UK using a die cast aluminium shell finished in black anodising. These housings are durable and lightweight, with replaceable stainless steel faceplates for customisation. The interchangeable sound nozzles are precision CNC machined and come in multiple lengths to suit different ear shapes and sonic preferences. The cable is made from high purity silver plated oxygen free copper for low capacitance and strong signal integrity, terminating in a reliable two pin 0.78mm connector system that is easy to replace or upgrade if needed.
