Sennheiser HD 650 Open Back Professional Headphone Review

When we listen to music files from our PC, Mac, or from services such as Google Play, Spotify or Apple Music, the output of our computer can prove to be a bottleneck that limits the ability to provide sufficient energy and clarity that are expected in a device of good quality.

Pros

They are very comfortable and the sound is excellent, I do have a trained ear, but it is not necessary to have it to realize that it doesn't matter what type of music you listen to, electronic music, classical music, folk, they all sound good. Of course the sound will also depend on the sound source being adequate. In addition the sound is very faithful, without added tones, what you hear is what is in the recording.
Ergonomically, is surprising how comfortable they are despite their size. The material of the pads is very soft and produces no feeling of friction or heat. In a few seconds you forget that you are wearing them. Great for moderately prolonged auditions.

Cons

Steep price

Verdict

Because of their profile, these headphones are excellent for all types of music, especially modern and electronic music. In addition, the preponderant basses and their excellent isolation are features that deserve to be mentioned. Being one of the most comfortable headphones on the market for long listening they  can be used for 4 or 6 hours without getting tired.
It may not be optimal for people who like a bright profile (for which we recommend the Sennheiser HD800), but except for that, we think that they are a great option for the audiophile that have predilection for these kinds of sounds due that are specially designed for music lovers.
With a fairly high price, these headphones compete with very high performance products, and for some people seems a rather expensive whim, but in the long term we think that the product represents a very good purchasement.

Video-Unboxing The Sennheiser HD 650 

Design

It is noteworthy when analyzing this product, that the presentation in which it comes is a very minimalist and classic. The box is made from a premium type of cardboard, which protects the inside of the box of a more rigid material that stands out for its texture and the engraving of the brand. After opening the package you will see the headphones itself covered by a protective foam.
Discovering some Sennheiser of the HD 6xx series is always a special moment, and our first impression confirms that the packaging is of excellent quality, emphasizing the presentation of an item that will meet the needs of most audiophiles.
Immediately afterwards, the magnificent look of a pearly paint and bright gray color, the good velvety finish of the pads, and the great materials, which despite the plastic used in its structure, call the attention of the viewer for their good  construction, as well as the comfort that the gel mesh of the headband gives to the orient.
Speaking about construction, we did not expect less from this great firm, which doing it by hand shows great detail, and also gives the feeling that you are in possession of a very durable product.

Sound Of The Sennheiser HD 650 Open Back Headphone

The highs feel shifted and somewhat muted, perhaps the weak point of this product, they do not present that liveliness but the quality of the full sound makes overpass  its negative side.
The mediums are the protagonists, soft warm, and emotional, we love the way in which the headphones reproduce the male and female voices, as well as the guitars .
As far as the bass is concerned, they are superbly complemented with the highs making a balanced combination that highlight the fidelity of the sound. Congratulations to Sennheiser engineers, who with great creativity displayed an excellent job that resulted in a high quality product.

Lateral View

Sennheiser HD 650 Headphone Sensitivity

Referring about sensitivity, with an impedance of 300 ohms, they seem to be appropriate for using them with a mobile or PC , but it would be better if they are complemented with an amplifier,  because they ask for more voltage than mW. If we use the formula:
Power = squared voltage, divided by impedance, we will realize that having the same voltage, more mW is necessary when the impedance is lower.
Because of this, we have concluded that the great performance of the HD 650 can be improved using an amplifier, and the proof of this, is that observing its impedance graph in the bass section they have a peak of almost 500 ohms.

Value For The Money

In the media and on dedicated websites, it has always been established that the HD650 was one of the classics headphones that any music lover should try to acquire sooner or later.
I listen to all kinds of music: Rock, jazz, classical, electronic, opera, etc. , and although I can accept that it is very difficult to find a valid headset for all genres especially in the low frequencies, where personal preferences can vary diametrically.

In our humble opinion, if one can afford premium headphones with the right amplification, and we aim at headphones that shows high fidelity in all frequency ranges, combined with tonal balance (that is not always what some cheaper products offer), the truth is that with the generous bass control that these headphones  gives you, the money is very well spent.
Now, considering that the bass is controlled, now comes the issue of frequency balance, the way and amount in which bass, medium and treble are delivered, which we consider most important, because that will mark the personality of the headset.
If I had to choose a differentiating feature of this headset, I would choose the way it makes sound all kinds of recordings. In other headphones, the lack of padding of all frequencies is always particularly evident, as if the entire range were turned off and the separation of instruments resembled a mono recording. With the HD650 that is much more mitigated than in any other headset that I know.

Question 4: Can I use them on the iPhone?

Answer: The iPhone is not adequately powered for these kinds of products, and the Sennheiser HD650 ia intended to be used with a dedicated headphone amp. Amazon had a good return policy in case that you are not happy with them. The HD 650 is good for video games and several types of music, especially for vocals and jazz music. I listen to a lot of jazz and I am really satisfied with the product.

Last Thoughts Of the Sennheiser HD 650 Open Back Professional Headphone Review

Among what we liked most about this headphone is the highly optimized magnetic systems that achieve minimal harmonics and distortion of inter modulation, and the specially developed equalized sound. Made of a fine metallic and acoustic mesh that ensures precise sound on the entire surface of the headphone which make it stable in all types of climates.
The specially designed cable (detachable) made of highly conductive copper( with very low level of noise), and the sensitivity of the noise that comes from outside are characteristic that stands out in this product.
We would say that the  cherries of the cake are the extremely light aluminum vocal coils that ensure an excellent transient response.
