Sennheiser HD 400 PRO (700047)

Simple in terms of functionality, but at the same time very advanced in terms of sound, headphones that many reviewers called the heirs of the legendary Sennheiser HD 600 and HD 650 studio models. The model is located exactly between the middle and upper price segments, and its potential customers are musicians, sound engineers, engineers and music lovers who are looking for headphones with natural sound and high-quality articulation.

In form it is a full-size model of the Over-Ear type of open type, which is devoid of any passive noise isolation. Headphones are distinguished by good sounding with good bass articulation, well-developed mids and airy highs. The sound is generally similar to the legendary HD 600 and HD 650, which entered the market in the early 2000s. The manufacturer claims the reproduction of an extended frequency range - from 6 Hz to 38 kHz, which is almost twice the capabilities of human hearing.

In addition, the manufacturer promises a minimum harmonic distortion coefficient (0.05%), which is fully consistent with the level of HD 650. Sennheiser HD 400 PRO weighs only 240 g, so they are not particularly felt on the head and do not press if you carry them from morning to afternoon . For studio work, this is an important factor. The headband with a massive cushion is adjustable in a wide arc, and large and soft velor ear cushions fit neatly over the ears without completely covering them as in closed-type models.

Headphones have a resistance of 120 ohms, that is, they are quite loyal to the amplifier, without making any incredible demands on it. However, paired with a smartphone, tablet or other mobile device without a built-in amplifier, they will not play quite as colorful as they could. The headphones come with an additional 1.8m straight cable and a 3.5mm to 6.3mm adapter. The main three-meter cable is detachable.
