Headphones with a Balanced sound signature presents a precise sound and an enriching listening experience, where sounds are naturally presented without extreme emphasis on any region. With a pair of headphones with this sound signature, you can hear audio with clarity and detail. The sound is vivid and revealing, a perfect mixture of instruments and vocals, lows, mids, and highs. This sound signature works for most music listeners who like switching between various music genres like Classical, Jazz, Blues, Rock, Folk and Pop.

These Wired Headphones are designed for discerning music lovers. If you are someone who cares about audio quality deeply, you'll want a pair of Wired Headphones like these. You can expect these Wired Headphones to present you with a refined listening experience. The audio quality exhibited by these Wired Headphones is a beautiful mix of musicality, technical brilliance and high precision. These Wired Headphones deliver a spacious and open soundstage that compares listening to music on actual speakers.

As the name implies, anything branded a studio headphone will have been designed especially for use in a studio setting, with a particular focus on accuracy and transparency for monitoring and mixing. These headphones present an accurate image of your music than ordinary headphones, allowing you to hear every nuance and aspect of your music. Therefore, having a good set of studio headphones is just as important as any other piece of gear in your studio. These headphones provide a fresh perspective to that mix you’ve spent hours working. Essentially, giving you another set of ears.

Headphones with an Open-Back design are rather special in that they allow air to pass through the headphone ear cups to the speaker. What this means is that since open-back headphones don’t block surrounding noises as closed-back do, you’ll be able to enjoy an immersive sound experience. The sound is more natural and high fidelity due to the lack of pressure build-up. Open-back headphones create a feeling of space, presenting a feeling as if the musicians are all sitting around you. These headphones are perfect for critical listening sessions and mixing and mastering music due to their accurate soundstage presentation.

If you plug your wired headphones directly into your phone or laptop, you are probably not hearing them at their best. This usually happens because the amplifier in your phone or laptop is not capable enough to drive your headphones to their best. A dedicated headphone amplifier is an elegant solution for this, and it can power your wired headphones to their maximum capability. When you invest in a good pair of wired headphones that are hard to drive, it's worth getting a dedicated headphone amp as it will make your headphones sound even better.

A pair of headphones with a replaceable cable has many benefits, and one of them is if the connecting cable has a problem, it doesn’t mean that you have to buy a new one. If the connecting cable gets pulled or damaged, you can replace it and keep using your good-old headphones or IEMs. This way, your headphones will be protected and will last longer. With the advancements in cable manufacturing, you now get a variety of replacement cables with various termination options, lengths and quality.

This headphone is a classic. The Sennheiser HD650 isn't a new headphone, but it's still a favourite amongst audiophiles. The sound signature can be best described as 'reference grade' because so many people over the years have used this as a benchmark for use in the studio and at home. Pair it with a decent tube amplifier to hear it sing.

The Sennheiser HD 650 headphone has been engineered to give you studio-quality audio output. HD 650 features an open back design with an industrial-grade build, which allows the ear pads to fit comfortably and deliver transparent natural-sounding audio. The HD 650 reproduces subtle details in your tracks with a fluid signature tuned for hours of fatigue-free listening. You will quickly become captivated with the expressiveness and emotion whilst also enjoying the absolute control and precision of the headphones.

The Sennheiser HD 650 is designed with high-quality components to deliver pristine audio. Coming with a driver unit which these beasts produce an aural experience like never heard before, offering a tremendous frequency range of 10 to 39500Hz. The 42mm transducer deploys a 38mm diaphragm with an aluminium voice coil specifically tuned for overall treble and low-frequency presence, while the midrange is reproduced with lifelike composure. The neodymium magnets have been highly modified, reducing the air turbulence and providing you with a sonic experience that leaves you amazed. The lightweight aluminium voice coils promise a great transient response.

Everything about the HD 650 was made with more in mind, more details discovered, more musicality, and more time for monitoring. Made in Romania at a state-of-the-art production facility, the HD 650 combines the best of modern transducer manufacturing with the attention to detail required to handle a wide variety of acoustic materials. For example, the resonators feature stainless steel mesh to guarantee uniform performance after manufacturing. Even better, most parts on the HD 650 are modular, making it a dream to keep operational as your go-to reference monitoring solution.

A headphone that has been handpicked and made with genius craftsmanship with premium quality materials is bound to provide you with the luxury you have been pining for. The titanium/steel finishes of the headphones not only gives them a great look but add to the quality sound as well. The generously velour padded earpads provide unparalleled comfort, not to forget the generously padded headband, that make these headphones appropriate for long usage, without your head feeling sore. The insides of the speaker unit have a specific damping element, created from extremely fine acoustic mesh, that successfully covers the diaphragms and keeps them so in changing climates. The HD 650 comes bundled with a high-quality tangle-free & oxygen-free copper cable, which is extremely conducive and highly durable.

Paired with a detachable and impedance-matched cable, the Sennheiser HD 650 offers ultra-low capacitance. These cables come with an audiophile-grade ¼-inch / 6.3mm stereo connector that can be used with headphone amplifiers, A/V receivers, digital audio players and more. With 9.8 feet / 3m long cables, you can move around freely while the premium 6.3mm to 3.5mm / ⅛-inch adapter allows you to connect the Sennheiser HD 650 to countless other audio devices.

The Sennheiser HD 650 comes bundled with a custom modulated detachable cable made from highly conductive OFC copper wires. The oxygen-free nature of the cable allows for audio transmission with an ultra-low level of distortion and low noise floor. This is further enhanced by a Kevlar coating to enhance the durability of the cable. The cable included is 3 meters in length, featuring a dual-sided gold plated 1/4” connector. There is also an adaptor provided to convert the 1/4” jack to a 3.5mm jack for use with various devices.

FREQUENCY GRAPH

CHEAT SHEET

Regions of the frequency spectrum

SUB BASS
(20Hz - 80 Hz)

The first section of the frequency spectrum is the sub-bass. Everything below 80Hz is sub-bass, so generally, you need a subwoofer or a good pair of headphones (open-back headphones, for example) to hear this region. This region comprises instruments like the Kick Drum and the Bass Guitar. You should be able to hear Sub-Bass if you’re listening on monitors or headphones. But if you’re listening on a laptop or a phone, there’s no way you will hear that.

MID BASS
(80 Hz - 300 kHz)

After the Sub-Bass region, we get into the region known as the Bass or Mid-Bass. This region consists of everything between 80 and 300 hertz. In this area, we’ve got instruments like bass guitar and the low end of a snare. Lots of the low-end vocals as well, because male vocals are going to have the fundamental below 200Hz in most cases.

LOWER MIDRANGE
(300 Hz - 1000 kHz)

Next, if you go from 300 Hz up to 1000 kHz, this is known as the Lower Midrange, and this is a crucial region for music because this is where you get a lot of buildup with guitars, vocals, and even the top-end of the bass guitar especially. Lower Midrange is an area guilty of adding mud to a mix and clarity in this region lifts a track exponentially.

UPPER MIDRANGE
(1 kHz - 6 kHz)

Human hearing focuses inherently on this frequency range. So it’s crucial to get this range right. This region consists of the main focus of the track (e.g. vocals) and synths. Be aware that this is also where you can start to get into harshness and aggressive tones.

TREBLE
(6 kHz - 10 kHz)

After the Upper Midrange, we’ve got the Treble region between 6kHz and 8 kHz, and this is where things start to get harsh. This region is where we have brittleness from instruments like the Hi-Hats and Cymbals. This is also a crucial range for clarity and aggression, especially for female vocals.

AIR
(10 kHz - 20 kHz)

At the end of the frequency spectrum, we get to the Air region or the Top End. This region consists of everything above 10 kHz. This is where we have air and this is where we get a sense of shine and sparkle in our music.

What is the impedance on the Sennheiser HD 650?

The Sennheiser HD 650 comes with the impedance of 300Ω.

What do "Impedance" and "Ohms" mean?

Impedance is the so-called alternating-current resistance that headphones have under specific standard conditions. On devices with low output impedance, headphones are the louder, the lower their impedance is. In principle, we recommend that you choose headphones with low impedance for use on devices that are operated by battery/rechargeable battery (i.e. most portable devices such as smartphones, tablet computers but also notebooks). You can distinguish between high and low impedance. Usually, the gradations 18 Ω, 32 Ω, and 80 Ω are used in the low range. In the high range, 250 Ω are common. If you want to get the most out of your system (and it has the power to do so), choose a model with 600 Ω.

Don't sweat it, this Sennheiser - HD 650 comes with a warranty from Sennheiser that covers manufacturing defects. All products featured on Headphone Zone are backed by an original manufacturer's warranty.

"Sennheiser's flagship headphones have high-tech styling, extraordinary bass response, and an extremely comfortable design.The formidable HD 650 headphones are fit for a king."

"The HD 650 has superbly low harmonic distortion and precision sound reproduction across the entire frequency range. The bass is well balanced and crisp, with authentic deep bass reproduction."

"Sennheiser’s promise to give the HD 650 more room, especially for mid-bass, is definitely kept. This makes the sound of these headphones warmer than that of the HD 600."

A comfortable allrounder

I have been using HD650 for two years now and this is my experience:

Sound:
This does not have a neutral sound signature - it inclines towards darker tone. The bass, even though slightly more pronounced, sounds amazing – with a solid body albeit a bit slow, and blends beautifully with the mids. The mids are clear, slightly dark. Both male and female voices sound beautiful. Highs are the weakest point of this headphone. They are laid back and not bright. Personally I prefer this, because this allows for prolonged listening sessions without getting fatigued whatsoever.

I primarily listen to western classical music. For specifically classical – string instruments sounds wonderful with intricate details, percussions are good as well – but bit slow. For Piano though – I am not very happy with a rather thin sound. However – this just maybe due to the dac and amp. Indian songs are reproduced with excellent details with a soothing quality. Jazz sounds exemplary in my experience.

Source dependency:
HD650 sound quality is highly dependent on the source. I have high quality 320kbps MP3 which sound surprisingly veiled. FLAC does better, but even a very minute noise in the file is noticeable. WAV sounds the best. I did not notice any significant quality improvement with DSDs.

Different amps and dacs sound very different with this headphone. Better to mix and match depending on music preference. Note that you need a decent set of dac+amp for this headphone – else it will not do justice to the quality of sound HD650 can produce.

I use Fiio X5 II and Fiio E12A (this has a brighter tone which complements nicely with darker tone of HD650) as my all-time-use setup with HD650.

Summary:
Paired with a good amp and dac, HD650 is an amazing headphone for relaxed and lazy listening. This headphone is pure joy to listen to even for a prolonged time. If you just want to close your eyes and enjoy the music without being analytical – HD650 is possibly the best headphon...

Best bargain audiophile headphones

This headphone is more refined version of all time classic hd600. Initially it sounded muffled and bass heavy but after about 100 hours with isotek burn in track it sounds extremly clean and detailed. Bass and mid bass are lot fuller and sound has lot more body. Treble is one of the most clean and refined you would ever hear. There are no peaks to frequency response and sound is extremely smooth. I use it with chord mojo and it does full justice to mojo's insane resolution. People coming from beyerdynamic sound may feel the combo with mojo a bit on warmer side but I bet mojo plus hd650 combo is impossible to beat even with much more expensive headphones simply because this headphone has one of the least distortion figures. Impedance of 300 ohm goes very well with mojo and mojo gives plenty of volume and I never needed to go beyond green to light green volume of mojo and still plenty of volume range of mojo left. People looking for high end sound need not to see beyond thid headphone. Only one thing is that to enjoy the music fully with this headphone you need to listen in a calm environment as it is a open back design and easily affected by ambient sound. Overall great buy for audiophile and all music lovers alike.

So pleasant that one could call them the "Bose of Audiophile Phones"

These are very early days of my usage but the Sennheiser HD 650 do sound wonderful. They not as spacious or as sharp as the AKG K712 - the soundstage is kind of narrow and the sound is on the warmer side. And to be honest, they really needed better design on these - the plastic headband seems a little on the fragile side. But heck, you forgot all that when you hear them. I would say that they are best suited for music because they sound incredibly, well, for want of a better word "pleasant." There is the slightest stress on bass - about as much as you can get on an open-back headphone set - but the overall effect is very pleasant. I love to call them the "Bose of Audiophile Phones." Yes, they do benefit from a decent DAC - I mainly used a Fiio Q1 Mark 2, but the interesting part is that they worked reasonably well even off Apple's lighting and USB Type C connectors, which is surprising. I hope to be using better DACs and let's see how that changes matters.

I first heard them in 2010, and well, I recently got them for about Rs 22,495 - close to half what they once cost. One heck of a deal.

HI there,
We are so happy you took out time & elaborately reviewed the product. We are sure this will help our customers to make an even better & informed decision.
