Reference – Grade Headphones For Project And Professional Mixing Sessions

The frequency range of HD 400 PRO was developed, to be honest, across the board, especially when it comes to the lower end of the spectrum. The angled transducer design allows for unique stereo imaging, reproducing the spatial sound of your mix.
In other words, what goes in is what comes out. Reproducing analytical audio, the HD 400 PRO reference headphones are your everyday tool to get the job done.

Open Back, Open Mix

Open ear cups allow for a wide and transparent soundstage, recreating the optimal listening position found in high-end recording studios. Artifacts of a confined space are a thing of the past. These studio headphones do not construe but rather ensure neutral transparency – the groundwork for the best mixes.

The Perfect Synergy Of Comfort And Precision

Let’s face it: mixing sessions are never quick. The HD 400 PRO’s lightweight design allows you to focus on your project for hours on end. Articulating earcups, velour earpads, and an adjustable headband allow for adaptability and comfort to perfectly match the shape of your head.
Our self-developed 120-ohm transducers are tuned for accuracy to deliver every detail of your mix. The highly efficient driver magnet provides clarity while its damping system manages ventilation. This results in deeper bass while extenuating distortion that otherwise impacts sound quality — a difference professional users will appreciate.

More Tools For More Options

The HD 400 PRO features a detachable coiled cable. For convenience, a straight cable is also included in the delivery. With a screw-on adapter, you can connect to your mixing desk, audio interface or any audio device that has a 1/4-inch (6.3mm) or 1/8-inch (3.5mm) output.

Delivery Exclusions

PLEASE NOTE:

Some products are exceptionally large, heavy or bulky and require specialist freight services. This typically includes items such as large PA speakers, dual 15″ speaker cabinets, dual 18″ subwoofers, flight cases and other oversized or very heavy equipment.

We work hard to keep our prices as competitive as possible and, in most cases, delivery is completely covered by our standard shipping rates. However, for certain oversized items being delivered to regional or outlying areas, the actual courier cost can be significantly higher than standard deliveries. This is also owing to factors completely outside of our control (petrol costs and rising costs of delivery by courier partners)

If this applies to your order, we will always contact you before dispatch to discuss the available options. These may include:

Proceeding with a small additional freight contribution.
Collecting the order from one of our suppliers or a nearby courier depot where available.
Cancelling the order for a full refund if a suitable solution cannot be reached.

Please be assured that we only request an additional freight contribution in exceptional circumstances where the courier cost is substantially higher than normal. Our goal is always to deliver your order at the advertised price whenever possible.

If you’re unsure whether an item may be affected, you’re welcome to contact us before placing your order and we’ll gladly provide a delivery estimate.

Thank you for your understanding and ongoing support!
