Design of Sennheiser HD400 Pro

The most accurate and neutral reproduction is achieved with an open-backed design, which is common among Sennheiser HD400 Pro headphones. It also implies that there is some sound leakage, particularly at greater volumes, because sound can escape rather than be held inside. It’s important to be mindful of this while monitoring vocals or acoustic guitars recorded with a microphone.

On the other hand, they are incredibly accurate when it comes to replication. They have excellent stereo separation and low distortion, even at high SPLs, thanks to a wide frequency response of 6Hz to 38kHz and a wide frequency response of 6Hz to 38kHz. Panned sounds that aren’t as noticeable on other systems suddenly become pin-sharp on this one. Sennheiser HD400 Pro is quite exposing, making the layers of a mix more visible and distinguishable. The diverse mixing and mastering processes are more visible than ever when listening to recorded tracks from different eras.

Sennheiser HD400 Pro headphones box includes two detachable cables and a 3.5mm to 6.3mm adaptor. One is a 3m coil cable, and another one is a 1.8m straight cable. So that, makes it ideal for connecting to your mixer or interface from a distance. The connection is on the left ear cup, and it’s a shame there isn’t one on the right, since this would provide you the most flexibility in terms of keeping cords out of the way. There are no other bells and whistles on the cables, such as wireless or microphones; these are solely for wired listening.

Internally, Sennheiser HD400 Pro employs specially designed 120-ohm transducers that sit at a little angle inside the cups to create a triangular listening position similar to that of monitor speakers. This does not imply that the fit is abnormal, as the angling is done within the cups themselves. The phones have an open back helps to minimize overheating during long sessions. It also avoids the boxiness that closed-back devices sometimes have.

Even if you have a good set of speakers, you’ll need headphones for mic recording, mixing, working at night, and working in different locations or on the go. Wireless headphones that rely on Bluetooth have too much latency to be practical for live recording, as good as they have gotten.
