Sound Quality

The Sennheiser HD 650 headphones have received widespread praise for their outstanding audio reproduction. The headphones have a dynamic, open-back design that lets you experience a more authentic and all-encompassing sound field. The soundstage iѕ large and immersive, faithfully recreating the performance.

The low end is punchy and rich without being muddy or overwhelming. The highs are bright and clear without harsh or sibilant, and the mids are warm and rich. So, these headphones have a greater frequency response range (from 10Hz to 41kHz) than many others in their price category, so they accurately portray the whole range of sound frequencies.

This device provides a natural sound profile that does a great job of accurately recreating acoustic music, jazz, classical, and voice performances. They are also well suited to rock, pop, and electronic music because of their wide frequency range.

The headphones have an excellent build quality and provide sound that audiophiles and industry professionals have praised. So, the headphones provide the best sound quality in their natural and immersive price range.

Connectivity and Features

The detachable cable of this model measures 3 meters in length and plugs into a standard 6.3mm connector, making the headphones compatible with a wide variety оf devices. Also, Kevlar is woven into the cable to make it stronger and less likely to become tangled.

The headphone’s open-back design is noteworthy since it facilitates a more authentic and all-encompassing listening experience. But, unfortunately, that also means that these headphones are not ideal for usage in busy environments or public spaces, as they do not isolate external sounds.

This product can only be used to its full extent with the help of a headphone amplifier due to its high impedance of 300 ohms. That could be a dealbreaker for some consumers, as they would have to buy an external amplifier to use the headphones’ full potential.

One potential downside is that they do not include supplementary capabilities like noise cancellation or wireless connectivity.

The headphones’ dedication to providing great sound quality and ergonomic design makes up for the absence of some of the current capabilities offered by other headphones in the same price range.

Competitors Comparison

This model is priced competitively, and several comparable headphones on the market provide similarly high-quality sound and convenient features. Here’s how they stack up against some of their rivals:

Another well-liked set of open-back headphones in a similar price range is the Beyerdynamic DT 990 Pro. Users may prefer it over the Sennheiser HD 650 due to its brighter and more detailed sound. Yet the DT 990 Pro doesn’t feel as natural on the head, and its construction isn’t as sturdy as Sennheiser’s model, so it’s not the best option for extended wear.

The Audio-Technica ATH-M50x iѕ a closed-back model that blocks ambient noise while producing rich, detailed sound. The M50x, on the other hand, has a narrower soundstage and doesn’t have the HD 650’s distinctive natural sound.

The Sennheiser HD 600, a model before the HD 650, shares the HD 650’s trademark sound and general layout. The HD 650 offers a wider frequency range, but the HD 600 has a little narrower one, and its neutral sound profile may not appeal to everyone.

The Philips Fidelio X2HR is an open-back headphone with a sound characteristic comparable to the Sennheiser HD 650 but with a more expansive soundstage and punchier bass. But, the X2HR’s construction is less sturdy and less pleasant to use.

Although other headphones are available for around the same price as the Sennheiser HD 650, which provides similar sound quality and functions, the HD 650 stands out due to its superb build quality, comfy design, and authentic sound character. So, it is the best option if you want headphones that won’t break the bank but will last a long time.


The Sennheiser HD 650 are open-back headphones highly recommended for serious music listeners, studio musicians, and anybody who places a premium on premium sound and comfort. These headphones provide a realistic and all-encompassing listening experience through their expansive soundstage, robust bass, warm mids, and crystal-clear highs. Also, the headphones’ lightweight construction and soft velour earpads make them pleasant to wear for long listening sessions.

These headphones aren’t the most feature-packed in their price range, but what they lack in cutting-edge technology, they make up for in superior sound quality and wearability. Unfortunately, their high impedance of 300 ohms necessitates using an amplifier to reach their full potential, but for those willing to invest, the outcome is worthwhile.

This piece is an excellent purchase for anyone searching for а premium pair of headphones that will last for years while maintaining their superior sound quality and comfortable fit. So, they are widely regarded as the best option in their price range, both by experts and regular customers.
