The highs are very good. Loads of precision and readability with no smidge of harshness. For critical studio work, there’s nothing better than a clear top end that won’t irritate you over longer periods. And that’s precisely what the HD 400 Pro presents.

The mid-range is equally satisfying. A superb range and depth that highlights the source without bringing it too ahead. Warm and airy because of the open-back design. The sound stage and imaging are additionally better than we anticipated at this value level. This could possibly be because of the angled transducers which have gotten more and more common. It helps replicate the direction of studio monitors for an extra clear and correct delivery.

Sennheiser HD 400 Pro Frequency Response

Sennheiser HD 400 Pro Build

The headphones use comfy velour earpads with an adjustable headband for sizing. With people with a bigger head than most, there was nonetheless plenty of room for a snug fit. We did discover that it has a firm clamp, inflicting some pressure across the ears.

Whereas this helps preserve a decent seal, in our case it additionally led to taking extra breaks than normal to rest the sides of my head. The housing appears sturdy for day-to-day studio use, however, all of the important elements are made from plastic, doubtless chosen to keep the weight down and make them extra affordable.

The HD 400 PRO seems strikingly much like the very fashionable HD 560S within the Sennheiser audiophile lineup. We didn’t immediately examine the 2, however, they do have rather a lot in common on paper. The 5XX collection has been around for a very long time—the ‘S’ in HD 560S designates a model new 120-ohm transducer.

This move was a direct success, so it’s no shock that Sennheiser would subject a PRO model with the identical transducer. It makes use of a specialized polymer mix in its diaphragm that improves transient response and detail above 10 kHz. The drive magnet achieves higher bass extension via excessive power, and a damping system manages airflow.

The brand new transducer design brings the distortion score right down to a formidable < 0.05% THD. The frequency response is listed from 6 Hz to 38 kHz, and it ships with each coiled and straight cable together with a 1/8” to 1/4” adapter.

The HD 400 PRO features angled transducers, and mixed with its open ear cups, can produce a large and correct soundstage. This selection of angled transducers (which is turning more and more frequently) is alleged to supply drastically improved distortion characteristics, notably at an excessive sound pressure level, which could be very apparent on first listen.

Transients form and dissipate with a purity that actually permits you to hone in on a sound in a minute element. This mixed with its open-back design offers an unlimited soundscape that stretches throughout the peripherals and envelopes the listener with unimaginable readability that’s sure to impress. That is by no means more obvious than when assessing panning choices and where all the things sit throughout the stereo field.
