Full Description

Quantum ES2

Ultra-low latency tracking

Experience recording with near-zero delay with the Quantum ES 2's custom low-latency driver. This feature is a game-changer for musicians and producers who need to monitor audio in real-time without the distraction of lag. It allows for tighter performances and easier alignment of live instruments and vocals during multi-track recording sessions, making it a reliable tool in any professional recording environment.

Revolutionary MAX-HD mic preamps

The Quantum ES 2's MAX-HD mic preamps are a result of three decades of research and development, providing up to +75 dB of clean gain. This makes them highly effective for various types of microphones, from dynamic to condenser, ensuring every recording captures the true essence of the sound source. Their digitally-controlled analog nature allows for precise settings, which results in transparent and noise-free recordings.

Fender-enhanced instrument inputs

Quantum ES 2 boasts an instrument input designed alongside Fender engineers, offering unmatched quality for guitar and bass recordings. This input is optimized to reproduce the intricate dynamics and tonal characteristics of your instrument, ensuring every strum or pluck is detailed and true to the original sound. It’s ideal for musicians looking to achieve studio-grade recordings at home.

Comprehensive software bundle included

Jumpstart your recording journey with six months of access to Studio One+ Professional Edition. This package not only provides a robust recording platform but also includes a variety of add-ons to enhance your production capabilities. Whether you're mixing, mastering, or experimenting with new sounds, the included software suite meets all your needs, enabling you to deliver polished, release-ready tracks.

HD9 Closed-Back Studio Headphones

Professional audio clarity

Built for precision monitoring, the HD9 headphones use high-quality 45mm neodymium drivers to deliver a wide frequency response from 10Hz to 26kHz. This ensures deep, accurate bass, balanced mids, and detailed highs, making them perfect for critical listening, mixing, and mastering. The closed-back design enhances sound isolation, preventing bleed into microphones during recording sessions.

Flexible design for studio and stage

For musicians, DJs, and producers, flexibility is key. The HD9 features rotatable earcups that swivel 180 degrees, allowing for one-ear monitoring while keeping an ear open to external sounds. This makes them an excellent choice for live mixing and DJing.

The adjustable headband ensures a secure and comfortable fit, adapting to different head shapes without adding pressure. The lightweight construction allows for extended use without discomfort, making them a reliable option for long studio sessions.

Built for long sessions

Comfort is essential for extended use, and the HD9 headphones are designed with soft, cushioned ear pads that rest gently over the ears. This reduces fatigue, allowing users to stay focused on their work for longer periods.

The lightweight yet durable build ensures they can handle the demands of daily use - in the studio or on the road. With a high power-handling capacity of 1,800mW at 40 ohms, they maintain clarity even at higher volumes without distortion.

Essential accessories included

The HD9 headphones come with a high-quality 3m straight cable, giving users the freedom to move around their setup without restrictions. The included gold-plated 1/8-inch to 1/4-inch adapter ensures compatibility with various audio interfaces, mixing consoles, and professional gear.

A protective storage bag is also included, making it easy to transport the headphones safely between sessions. Whether working in the studio or taking them on the go, the HD9 provides the tools needed for professional-grade monitoring.
