The Sennheiser HD 650 are full-size, open-back headphones that hit the market in the early 2000s and haven't lost their relevance ever since. The model is a studio classic with a well-balanced sound, chic detailing of mids and trebles, as well as a unique ability to convey the rich articulation of live instruments. Proprietary dynamic drivers with a 42mm transducer and a 38mm diaphragm are capable of reproducing a frequency range from 12 to 41000 Hz, while generating a minimum of harmonic distortion (factor < 0.05%).

With its meticulous analytical nature, the HD 650s have established themselves as either main or back pair in hundreds of recording studios around the world. It's also a great choice for audiophiles looking for premium headphones with an honest, uncolored sound. The ergonomics of the earphones do not lag behind their sound: velvet ear cushions lie on the ears like an elven cloth, a sliding headband with a massive cushion provides a secure fit to the head, and the open design of the earphones provides not only amazing lightness and natural sound, but also relieves pressure on the ears that cause closed and semi-closed headphones.

Like all headphones of the 600 series, the HD 650 has a high impedance (300 ohms) and is very demanding on the signal source. To swing them to the fullest, the owner will need a powerful signal source with good gain. For example, an audio receiver or a sound card with a high-quality preamplifier. For connection, a 3-meter Kevlar-reinforced OFC cable with a 3.5-6.3mm adapter is provided, which allows you to make friends with headphones both with studio and home equipment. The cable can be replaced if necessary, as it is removable.

Excellent, especially the symphonic space collages of Klaus Schulz, Worthy of weight in the sense of headphones, although Schulz too), I recommend both.
if the head is big it puts a little pressure on the brain

Basically it produces sound without embellishment... Very cool sound through high-quality equipment
The design itself says that the headphones are not for amateurs. The sound is good at all frequencies. The main thing is that the bass is not embellished, but simply natural, detailed sound is transmitted. The output music is natural, the notes are clearly audible
Many people complain about the high cost, but there is no point in criticizing the cost, since they are designed for professional use, and such equipment, if my memory serves me correctly, has always cost a decent amount

German quality studio recording

German quality always inspires admiration, and the Sennheiser HD 650 headphones boldly fit into high standards. The elegantly executed model can be used for both professional and amateur purposes, leaving only positive impressions.

Appearance

The design of the headphones can hardly be called extravagant and refined: everything is simple and tasteful. The cups are oval in shape and large enough to cover the entire ear. As in many other Sennheiser models, the familiar felt was used for the ear pads. Although it is comfortable to use, it will take time to get used to it. The design itself is well assembled and inspires confidence. Detachable cords (mini-Jack (3.5 mm), Jack (6.35 mm) on the one hand are delightful, on the other hand, experienced musicians believe that the original cord should be replaced immediately if you plan to use the device for professional purposes.

sound

The Sennheiser HD 650 headphones can be safely called full-fledged monitors that allow you to work in a recording studio. It is worth noting that when working on a summary, they will become real helpers, since the clarity and detail of reproduction are at a high level. The model is able to accurately convey exactly the sound that was originally intended for the recording.

It is not even necessary to speak separately about the quality of low, medium or high frequencies, since the entire frequency range is verified and does not fail even on second-rate musical compositions.

However, you need to understand that when listening to tracks through a mobile, you can never get the effect of "studio". In the case of this model, there is no limit to its finicky regarding the sound source. With ample opportunities to open any genre of music, if you don’t please with an amplifier, you will get a modest sound with a “Chinese” tinge.
