High-quality studio headphones

The Sennheiser HD-400 Pro is a pair of open-back, circumaural studio headphones that conceal highly sophisticated technology behind an unpretentious appearance. The black headphones impress with a very wide frequency range, from an ultra-low 6 Hz at the bass end of the spectrum to as high as 38 kHz in the treble range. The HD-400 Pro is intended to allow analytical sound judgements to be made. Accordingly, manufacturer Sennheiser describes its sound as natural, transparent, and precise. These headphones also work with Dear Reality's dearVR Mix software. A technology called Spatial Headphone Compensation (SHC) is used here and ensures a reliable assessment of audio mixes in different virtual listening environments so that a mix can be optimised for as many listening situations as possible. The scope of delivery includes two different interchangeable cables with 3.5 mm mini-jack connectors as well as a 6.35 mm jack adapter.

Powerful reference model

Sennheiser presents the HD-400 Pro headphones as a reference against which the quality of other headphones from the manufacturer should be measured. Its features include angled drivers that are supposed to provide the best possible stereo image. With all of the sound refinements that these dynamic headphones offer, the maximum sound pressure level they produce measures a hefty 110 dB. If the HD-400 Pro is to deliver such a high volume despite its 120-ohm impedance, it is best powered by a headphone amp that can deliver a decent output voltage. For this reason, a separate headphone amp is recommended for laptop users and users of smaller audio interfaces in order to fully exploit the qualities of this open-back, over-ear model.

For friends of wearing comfort and signal fidelity

The Sennheiser HD-400 Pro is a good choice for mix engineers who want to judge ultra-deep bass with their headphones. Mixers who greatly value differentiated highs will also get their money's worth here. And thanks to its low harmonic distortion, audio enthusiasts who expect a very clean signal with hardly any distortion will also find what they are looking for. Fans of high wearing comfort will get a suitable tool with the HD-400 Pro as well: With its replaceable velour ear pads, it lies comfortably on the skin and, with its low weight of only 240 g without the cable, little to no feeling of fatigue can be expected, even during long listening sessions. Those who want to work with their studio headphones in a completely relaxed manner and without pulling on the cable can use the HD-400 Pro's straight cable, which has a practical length of 1.50 metres, instead of the included three-metre coiled cable.

About Sennheiser

In June 1945, Prof. Fritz Sennheiser founded the Wennebostel Laboratory, which initially produced measuring equipment. Commissioned by Siemens in 1945, the young company developed the MD-1 microphone, which was launched in 1946. After the development of further microphones, the company was renamed Sennheiser Electronic in 1958. Two years later, Sennheiser introduced the MD 421 dynamic microphone, which is still in production today and still held in high esteem by many sound engineers. Further groundbreaking developments, such as the HD 414 headphones and the MD 441 microphone classic, hugely enhanced the company’s international reputation, eventually making Sennheiser one of the leading manufacturers of microphone and headphone systems in the world.

Editing, recording, and mixing

Amateurs will treat themselves to the Sennheiser HD-400 Pro in order to implement high-quality headphone monitoring in their home studio, while owners of project studios will use this circumaural model for signal assessment in multimedia projects. But studio professionals can also turn an ear to the HD-400 Pro: With its light weight, it is ideally suited to use in the control room when it’s time for another long mixing or recording session. Due to the open design, these headphones are primarily suitable for recording situations in which no instruments are recorded via microphone. And despite its compactness, the included coiled cable provides plenty of reach at the control desk, at the mixing console, and in the recording room. In busy situations in the mixing or control room, the single-sided cable connection of the headphones also ensures freedom of movement.

Fantastic!

Murluc 20.01.2022

At first I was sceptical that these would be worth their money because I already have two other sets of studio headphones from different manufacturers, but these blew me away when I put them on. The open back design is phenomenal and the headphones work great together with Dearvr Mix to give you the actual feeling of sitting in a mixing room, unlike the other two pairs I own. These headphones aren't the fanciest, they don't fold or twist into a smaller size for easy travel, but what they do is deliver you a fantastic sound that let's you hear what you couldn't hear before. They're basically limited to a studio-like environment or for home use but I highly recommend you get yourself a pair and check them out yourself!

Ein sehr guter Kopfhörer für Mixing/Mastering und Musikhören

Underrated dude 30.01.2022

Der Sennheiser HD-400 Pro ist meiner Meinung nach ein sehr guter Kopfhörer für Mixing/Mastering und Musikhören. Folgende Kopfhörer habe ich genutzt, bevor ich Sennheiser HD-400 Pro getestet habe: Sennheiser HD-201 und AKG K-92.

So, nun zum Sound des Kopfhörers (Sennheiser HD-400 Pro) :
Dieser Kopfhörer kann meiner Meinung nach sehr gut für analytische Zwecke genutzt werden. Er hat einen Frequenzbereich von 12Hz-38kHz, zudem überzeugt er durch einen sehr neutralen Frequenzgang. Die Impedanz von 120 Ohm ist kein Problem, wenn man einen guten Verstärker nutzt.

So, nun zum Tragekomfort des Kopfhörers (Sennheiser HD-400 Pro) :

Der Tragekomfort ist in Ordnung, weder besonders gut noch besonders schlecht, bei mir (ich bin Brillenträger und habe viel Haare auf dem Kopf, evtl. vielleicht sogar einen leicht breiten Kopf) ist es so, dass ich evtl. nicht länger als 90-120 Minuten Musik am Stück mit diesem Kopfhörer hören sollte.

So, nun zur Verarbeitung des Kopfhörers (Sennheiser HD-400 Pro) :

Der Kopfhörer scheint stabil zu sein, dennoch erwarte ich eine höhere Verarbeitungsqualität bei Kopfhörern in dieser Preisklasse. Die mitgelieferten Kabel geben keinerlei Anlass zur Beschwerde.

So, nun zum Preis/Leistungsverhältnis des Kopfhörers (Sennheiser HD-400 Pro) und einer Alternative:

Der Kopfhörer kostet 249 €, was meiner Ansicht nach ein gutes Preis/Leistungsverhältnis darstellt. Alternativ, falls euch dieser Kopfhörer zu teuer sein sollte und ihr wollt einen Kopfhörer, der einen ähnlichen Frequenzgang und Frequenzbereich hat, dann haltet Ausschau nach dem Sennheiser HD-560 S. Sennheiser HD-560 S wird jedoch als Hifi-Kopfhörer eingeordnet, während der Sennheiser HD-400 Pro offiziell als Studiokopfhörer bezeichnet wird.

Fazit:

Der Studiokopfhörer Sennheiser HD-400 Pro ist sehr gut einsetzbar für Mixing/Mastering. Das Musikhören mit diesem Kopfhörer bereitet mir große Freude. Für Recording sollte man jedoch einen anderen Kopfhörer nutzen ( Kopfhörer mit niedrigerer Impedanz und einem höheren Schalldruckpegel), damit keine unerwünschten Nebengeräusche über das Mikrofon mit aufgenommen werden. Der Preis von 249 € ist zu 80-85 % gerechtfertigt.

Mon meilleur casque

vincelebleu 25.03.2022

Excellente qualité de son, aigus très précis, mediums agréables et basses très propres. Niveau de sortie honnête pour 120 Ohm.
Devenu mon casque principal, ce HD-400 pro me permet de faire du mix au casque et d'avoir un résultat cohérent sur d'autres systèmes d'écoute (voiture, casque de téléphone, enceintes de monitoring ...).
Très confortable, il tient bien et ne me fait jamais souffrir, les coussinets en velours y sont sans doute pour beaucoup.
J'ai découvert avec ce modèle le plaisir et le confort d'un casque ouvert, qui me permet de ne pas être "enfermé" dans ma musique quand je mixe et de pouvoir entendre mes collaborateurs (ou mes enfants ;-) ) quand ils me parlent.
Bien entendu et de ce fait d'être ouvert, la musique sort un peu du casque et peut générer un peu de "repisse" dans les prises de micro à condensateur (c'est pourquoi j'utilise également un autre casque sennheiser fermé pour cet usage). Néanmoins, c'est souvent avec le HD-400 que je fais mes prises de voix (en mettant mon playback à un volume raisonnable dans le casque) car la sensation acoustique d'un casque ouvert me fait chanter plus naturellement qu'avec un casque fermé avec lequel, à l'inverse, j'ai la mauvaise habitude de modifier inconsciemment ma façon de chanter.
Après quelques semaines d'utilisation, je n'ai constaté aucune fragilité (bon ok, je suis soigneux), la prise femelle du casque qui accueille l'un des deux câbles (droit ou torsadé) maintient parfaitement le câble et semble robuste.
Une boite de transport, même sommaire, aurait été la bienvenue car j'aime emmener mon HD-400 pro un peu partout pour enregistrer et mixer.
PS : je n'ai QUE des casques sennheiser, mais pourquoi changer ? je les adore.
