Sennheiser HD 650

Sennheiser HD 650 best priceSpecifications


  • best price: check amazon! | check eBay!
  • type: open back. Closed back vs. Open back headphones.
  • fit: circumaural
  • impedance: 300 Ohm
  • frequency response: 10 – 39.5 kHz
  • replaceable cable: yes
  • cable length: 9.8′
  • plug size: 1/4″ (1/8″ Adapter Included)
  • weight: .57 lbs.
  • material: OFC copper (kevlar reinforced), velour ear pads
  • color: grey and black metal flake finish


These are some of the most accurate and well respected headphones on the planet. They are a little warmer, lusher, and thicker than their younger brother, the HD 600. They are also a bit more refined.

They are also a little less neutral and more enjoyable to listen with. As an open back model, these will leak sound so be weary of that and know that they perform best in an isolated studio environment, absent any extraneous noise and distraction.

Another thing to note is the impedance level. At 300 Ohms, these will need an adequate amplifier to reach their full potential.

More on amps a bit later!!

They take a bit of burn in time to really get acclimated, so prepare to really be impressed after around the 50 hour mark. Things start to open up considerably and everything kind of settles in. The sound becomes focused and tightly in place, which results in a very clean overall signature.


  • Extremely accurate and transparent
  • Great body, warmth, and smoothness
  • Nice sound-stage and imaging. You are able to place where the musicians are on stage, and being an open backed can, the sound won’t get trapped in your head and leave you fatigued.
  • A forward and engaging mid-range. helps with the presentation of the male voice.
  • Tight and authoritative bass response. less neutral than the HD 600. The bass, rather than being bloated and loud, is accurate and precise. You will be able to hear the tone of a kick drum as well as different textures in frequency. An important thing to remember is to make sure your sound source is of good quality. These will reveal flaws in haphazard mix downs and masters.
  • Not too picky about which amp you choose to pair with it. Sounds pretty fantastic with most amps.
  • Very versatile in terms of genre, handling a wide range of musical styles. Rock music is it’s strongest suit.
  • Comfort. those velour ear pads make it so you can wear these for hours and not get fatigued.
  • Replaceable parts, which ensures longevity out of your purchase.


  • Too smooth. Like Fonzie except not, these headphones are so chill that they may make you fall asleep!
  • Treble is lacking a bit. This is the “veiled” sound that people talk about in regards to Sennheiser headphones. Somewhat lacking in air and harmonic content. What is the Sennheiser veil?
  • HD 600. Many people prefer the more neutral HD 600 over the laid back sound signature of the HD 650. Others like the fact that the 650’s bass has a little more impact and weight behind it.

AMP/DAC Requirements

The great thing about the HD 650 is that it isn’t too picky about which amp you choose. At 300 Ohms, it does need one to reach it’s full potential, and a few good options would be:

Schiit Magni + Modi

  1. The JDS labs 02
  2. Magni/Modi combo (very common and a great option)
  3. E09k paired with the E17
  4. Bottle-head crack

Pricier options include:

Who this headphone benefits?

As alluded to in the open, this is a very versatile headphone that handles a wide variety of genres including:

  • Rock
  • Jazz
  • Classical
  • Hip-Hop
  • Soul
  • Acoustic

It’s bread and butter is most definitely for Rock music. This is in part due to the mid-range as well as the bass not drowning out other frequencies. The treble also has a lot to do with it.


Since 2003, It’s been one of the most beautiful sounding headphones around. It’s extremely accurate, has a really great mid-range, accurate bass, and is very comfortable over a long period of time. It’s treble is lacking a bit in the upper registers, and it has been criticized for being a bit too smooth, almost lulling you to sleep. Regardless, what you are getting with these is a brand new music collection. Why? Because they revolutionize everything you own, plus the music you haven’t heard. It’s like hearing all of your old favorites for the first time again. You will start to notice things in music that you never knew were there. This is one of the best things about higher end headphones. They make you realize what you were missing!

  • driver size: 40mm

Ah, the HD 700’s. Many people refer to these so lovingly as the HD 800’s evil twin brother. Or sister. Lol.

They are an exceptionally warm set of cans, but at the same time neutral and honest. They have a really good sound-stage as well, with a more relaxed treble reproduction. Where as the 800’s have been accused of an overly bright representation in the high end, the 700’s are much darker.


  • Warm character. These are very transparent, and elegant, with a musical warmth.
  • Spatial imaging good.
  • More relaxed in treble reproduction. Not harsh or Sibilant. What does sibilant mean?
  • Excellent accuracy. Same spatial accuracy and imaging capability
    as the HD 800.
  • True to life acoustic presence.
  • Bass reproduction is crisp and punchy.
  • Mid-range vibrant and clear.
  • Treble is crystalline and sharp without fatigue.
  • Superbly musical.
  • Non aggressive clarity.
  • Natural approach.
  • Broad dynamic range.
  • Light clamping force; extremely comfortable. Like you’re not wearing them. They are very comfortable over long sessions. The ear cups are also very large and deep.
  • Angled transducers, good Soundstage. What is Soundstage?
  • Not amp picky like the HD 800.
  • Good case.
  • They don’t over emphasize any particular frequency range. Neutral but warm. They allow for nuances in sound to be heard in each instrument and voice.
  • Clean and transparent sound.


  • Chord is somewhat iffy. It’s a solid chord overall, but may break near the 1/4″ phone plug. Alternatively, you could purchase the cable that sells with the HD 477 and 497, each of which fit the HD 700.
  • The Silver mesh material on the cups is very easily damaged.
  • While they are pretty solidly built, I saw quite a few complaints regarding some of the materials used. Specifically, people were saying they were disappointed over how much plastic was used in such a high end model.
  • Headband cushioning could have been better.

Amp/DAC requirements

I’ve read a lot about these headphones, and many say that they do need an amp to reach their full potential. However, The jack from the iPad and iPhone were both said to work phenomenally well.

What are people using?

  • Grace Design M903
  • FiiO E9
  • Beyerdynamic A1
  • JDS Labs 02
  • Schiit Valhalla
  • Schiit Magni/Modi (Amp & DAC)
  • FiiO E12
  • Schiit Asgard
  • Schiit Vali
  • Audioquest Dragonfly v1.2 DAC/Amp.

Steer clear of:

FiiO E7. This cannot drive them correctly.

My recommendation?

Go with the Schiit Magni/Modi combo. It’s an Amp/DAC that will work for a lot of different headphones, and is a great entry level option that won’t break the bank. Learn more in:

Who these headphones benefit?

I’ve heard them endorsed for the following:


Metallica, Genesis, Tears for Fears, Metallica, NWA, Sting, The Scorpions, Post Malone.


Jazz, Classical


Gaming, Watching movies.

Not as good for:

Pop, Rock, R&B. Some did say they were good for Rock, while others disagreed.

Thoughts from Stu’s notepad

  • Your listening volume should be on the conservative side. The music can get very loud very quick.
  • Music that had been previously obscured by layers of sound is suddenly audible and distinct. The HD 700’s are really a crystal clear sounding set of cans!
  • Chord should be stretched and left out for a day before use to loosen it up (removing knots and kinks), or wrapping the chord around a foam
    ball, and letting the outward pressure of the ball
    smooth out the odd bends in the fabric. You should be aware that quite a few people complained about the chord, but it was never a deal breaker.
  • These are darker sounding headphones with not as much treble presence as say the HD 800’s. With the 700’s it’s like being in the front row. With the 800’s it’s like your on stage.
  • These are not portable. They are designed for the home audio enthusiast. They also have zero noise isolation. Don’t expect them to block out any sound. You will be able to hear things going on outside of them as well.
  • You may not feel “connected” to the music or be emotionally involved. Even though you can hear every instrument in a complex orchestral work, and every subtlety, there is just this sense of artificiality.
  • May need to EQ these for EDM, as the sound can sometimes get a bit harsh/sharp/piercing.
  • They really need good source files. Expect the sound to be crappy from poor audio sources.
  • I’ve heard these are like a cross between the HD 600 and HD 800.
  • These have a more analog quality as opposed to digital.


The HD 700’s are an extremely comfortable, grand listening experience, complete with a really good sound-stage and a crisp overall sound. Be aware of the lackluster cable (which can be replaced if need be), and the plastic like feel.

Similarities & Differences


  • There are really no glaring similarities to speak of here. In actuality, these are vastly different headphones. Generally speaking, both have good sound-stage, comfort, and do well with classical and jazz.


  • The HD 650’s cable terminates in 3.5mm jack, and comes with a 1/4″ adapter. The HD 700 terminates in a 1/4″ jack and does not come with a 3.5mm adapter. You would have to purchase that separately.
  • The HD 700’s are easier to drive than the 650’s.
  • The cups are a bit roomier than the 650’s.
  • They are more comfortable than the 650’s.

The HD 700’s sound-stage is a bit better overall.


  • The HD 700’s vocals are more articulate and realistic. They have better resolution and are more detailed, upfront, and crisp.
  • The HD 650 is more musical, rounded and smoother.


  • The HD 700’s bass is a lot tighter.
  • The HD 650 is far more hollow and rounded, more natural. It’s smoother, with more punch (like Hi-C :P).


  • The HD 650’s treble is better, while the HD 700’s is a bit peaky and takes time to adjust to. HD 650’s is more natural and balanced.

Transients, speed, articulation

  • HD 700 wins out.

Timbre and Tonality

HD 650 is better. What is Timbre?


  • HD 650 good, but not exemplary.
  • HD 700 is more comfortable.


  • The 650 sounds distorted and messy in comparison
    to the 700. That’s not to say the 650 is a messy headphone. It’s just a bit outclassed here.

Final Word

It’s hard not to recommend the HD 700’s. They outshine the 650’s by a considerable amount, but aren’t that much more dough. In fact, the HD 700’s were originally a $1000 set of cans, that have now come down in price considerably.
