Sennheiser - Around Ear Headphones (HD 650)

ICON Loading...

These audiophile/studio grade headphones from Sennheiser are the first item I've seen where 100% of the reviewing customers gave it a '5'. Their only complaint is that you don't want to use them with cheap gear or substandard source material: you WILL hear the flaws. We should all have complaints that the quality is too good, shouldn't we?

Solid performers built for people who take their sound seriously, with a frequency range from 10 Hz clear out to cat and dog range (39,500 Hz, human ears tend to cut off at about 22,000 Hz)! Uses a 6.3mm phone plug, but comes with a 3.5 adapter for your smaller items as well. Designed for hours of use at a time, they are both comfortable and lightweight. The units are hand-picked in pairs for best possible match between left and right ears.

If you're serious about your sound, order them and put them on your ears now!

5 out of 5 eggsThe Hype Is Real

Pros: If you are a gamer or hobbyist who wants to start getting serious about their headphones please do yourself a favor and JUST START HERE. The hd650's are a legend of a reference class headhone and for a good reason. For years this was Sennheiser's flagship headphone and til this day it holds its ground to headphones well above its price range. It's exceptional comfort allows hours (done 12 hours plus no fatigue) of listening sessions.

Cons: Investment: This headphone as you may know by now reading this review, is that this headphone has a fairly higher impedance which requires an amp to juice them up a bit and get the absolute fullest sound from them. How much you spend is up to you, go run to the headfi forums for amp reccomendations to fit your budget.

Other Thoughts: Delightful headphone to listen to for hours on end. I was never as huge of a jazz fan til I could ear the sure delight that comes from these when I play it =). Whether its gaming or flac file listening sessions this headphone just ends up being my go to choice for an all arounder.

I will say that if you are a heavy EDM genre listener such as myself there are some more notable options for over ear higher dollar headphones that have the particular low extension when compared directly to these. HiFiman's HE-400 is an exceptional choice for EDM tracks but for rock and hip-hop the hd650's are still a delight.

5 out of 5 eggsGood headphones

Pros: Comfortable
Sturdy construction
Sounds great

Cons: Cable is much longer than I need and it gets in the way. Its not something I would dock an egg over, as others may appreciate it.

Other Thoughts: Beware, these headphones are "open back" design. Using them in an area with external noise pollution can negate the quality of sound your paying for.

5 out of 5 eggsFantastic Headphones

Pros: I'll go ahead and leave a non-audiophile review for these headphones. I'm not the type of guy that spends hours at a time on audio forums, and not the kind of guy who has an arsenal of words to describe his audio experience. I'm just someone that places a high value on very good sound quality.

I'm 17 years old and I spent my own money on these, as you can imagine I had my reservations about dropping this much money on a set of headphones. That being said I have to say that it was money well spent, and I'll tell you why.


My setup: usb --> schiit modi ---> schiit vali ---> sennheiser hd 650's ---> my ears

before this I owned a pair of audio-technica ath-m50s

When I first put these on I felt a very slight clamp against the side of my head, I was a bit worried that they were going to be uncomfortable because I'm quite particular about how my headphones feel. After waiting about 30 seconds for your head to adjust to having them on they become quite comfortable. They are surprisingly light and with the open ear design that lets air flow through etc I often almost forget that I'm wearing them. They have huge ear cups too so your ears will be completely enclosed, so you don't have to worry about how they fit on your ears.

When I first tried these on I honestly wasn't very impressed. This is due to me listening to a bass heavy song, and it being an mp3. Don't make this mistake, these headphones will make you hear the bad quality in mp3s, you're going to want to get a couple lossless audio tracks. After downloading a couple of fully lossless tracks however, I started to feel more and more that it was money well spent. I could hear things that I had never heard before. The musician moving his fingers over the strings, the thud of a keyboard, the slightest breath of a singer, vocals that used to get drowned out by other things in the background. Its actually quite impressive.

The bass is deep and controlled, the highs mids and lows all sound perfect, and the experience is truly immersive. You feel like sounds are coming from all around you.

I love the audio on these things, and I feel very lucky to have an audio setup like this. If you can find a way to afford these, I highly suggest purchasing them.

Cons: Need a good digital audio converter (dac) and headphone amp to sound good. The headphones have a high impedance so the amp is absolutely necessary to drive these headphones. Also would you really want to convert your audio with the $2.99 card build into your computer? ew

I got the schiit vali/modi and I'm happy with it. Although I do have plans to upgrade in the future as I've heard that these headphones scale very well the nicer the amp/dac setup that you have.

Also you're going to need to re-download much of your music library. These things are wasted on mp3s, you can easily hear the imperfections that they have. Fully lossless audio tracks will sound much much better, as I quickly discovered.

If you're a bass head you might want to rethink getting these. Don't get me wrong the bass is deep, but its more controlled/refined than other headphones. If you want to listen to dubstep with these I'm sure other headphones will give you a more skull shaking/satisfying bass drop. For most stuff though the bass does sound very good and doesn't overwhelm any of the other sounds.

Other Thoughts: As a side note I had my mom listen to these and she heard the difference as well. She said that "It was like all the sounds are separated out, so you can hear each of them"

5 out of 5 eggsSennheiser HD 650 Mini Review

Pros: Mid centric
Lush mids
Good bass
Non fatiguing
Very comfortable
Reference class
Can be considered end game for most

Cons: Needs heavy amping to sound right
A little too dark

Other Thoughts: Hi guys.

HD 650 made in 2013.

Brief Impressions of HD 650
It is a dark sounding, smooth, laid back yet high resolution headphone which is engaging enough to listen to hours at a time while being mid centric with a mid bass boost. The deep, tall and engaging soundstage is a good point as well.

The So Called Veil
I didn't find it on the Beta22 at all. On Ember I sometimes feel it, sometimes I don't. It is pretty good with Ember, though perhaps zero veil at all times, though. Not a deal breaker though. However, with a preamp phono with headphone out it did have a veil. So it does need heavy amping. Anything less than $200-500 on the amp and you will probably feel veil, and even then it won't disappear completely.
However, with Project Ember it is enjoyable and very often there is no veil.

Dark Sound
With RCA Black Plates 12AT7 it is darker, so the veil seems more present. With brighter tubes like Telefunken 12AU7 or brighter still RCA Clear Top 12AU7, the veil is less present and the tonal balance is more neutral. On the other hand, it sounded the warmest/darkest with the Beta22 but with no trace of the veil.
I recommend a bright amp with the HD 650 or a ultra high end neutral Amp. So if you choose a tube amp make sure that it uses a bright tube.

Low Volume Listening
Not ideal for low volume listening, especially because of the slight veil and HD 650 nature. However, moderate and loud volumes are very enjoyable. However, when I say moderate, that is probably low for most people. So this isn't a deal breaker for anybody, trust me. You will be fine! :)

Off an Asus STX
Sounds horrible. The RS 180/170 and Pioneer SE A 1000 sound okay, but not their best. However, after listening to it on the Project Ember for a few days, I decided to try the Asus STX amp, and it sounded bad. Not even comparable to the Ember. If you need to use Asus STX then it really sounds like a $50 headphone and you are better off with a HD 598 and Bravo Ocean.

Overall
It is an all rounder headphone though some people may not like it because of its dark nature. However, with the right amping, most people will get used to it. It definitely scales very well with an amp and does need a mid-fi amp as a minimum requirement if you really want it to perform as intended.

5 out of 5 eggsAudiophile Grade Goodness

Pros: Amazing sound. Pronounced, very punctual bass without muddying the highs and mids.

Cons: After listening to these when properly driven will make everything else you listen to like garbage unless it's also audiophile grade components.

Now I use the headphones even when I don't need to.

Other Thoughts: Driving this bad boy with Schiit Magnic and Schiit Modi and it's truly incredible.

5 out of 5 eggsFantastic Headphones

Pros: The Sennheiser HD 650's are incredibly comfortable to wear. When they come out of the box they are a bit tight but just give them some time and the headband forms to your head. The cushioning is very plush and breathable making these headphones great for using for extended periods of time.

The sound quality these headphones have are absolutely insane. They have a well balanced sound through out and are very flat, allowing you to customize the color of the sound to your liking. (Through custom EQ!)

Cons: Proper amplification is definitely required to get the most out of these headphones. Since they draw a nominal 300 ohm impedance, they are easily underpowered by the typical headphone jack.

These headphones will expose any defect in the source audio so make sure you have tip-top quality, MP3's will not cut it.

Other Thoughts: The headphone amplifier that I have used with these headphones is the Maverick Audio D1 Plus. Its an amazing unit at a reasonable price. Check it out!

5 out of 5 eggsThe HD650

Pros: - Detailed
- Transparent
- Responsive Bass
- Non-fatiguing, even at high volume levels
- Warm
- Comfortable (I wear these 8+ hours a day without any discomfort)
- Great for most Genre's of music
- Lightweight
- Scales well with amplification
- Modular

Cons: - Needs amplification to truly sound their best
- Plastic Material
-- Headband known to crack and break (Sennheiser's fix is about ~170$)

- Painted Headband
-- Flex on the headband overtime will chip the paint (would say this will inevidibly happen to most of the HD 600's, 650's, and 800's (not sure about 700s)

- Needs a lot of "burn-in" time to sound their best

Other Thoughts: Headphones are subjective and not everyone will like the 650's sound signature (more colored than neutral than what other's offer). These are known to have a warm and veiled sound, which either is bad or good depending on who listens to them. I for one love the way they sounds.

Since the drivers have 300 impedance (more than most), it is highly recommended to use a headphone amplifier.
-- I use a "UHA-4 Leckerton Audio DAC amplifier"

These require at least 100 hours of "burn-in" time, and around 500+ hours to hear their true capabilities, so don't be surprised if the headphones don't sound great after only a few hours of use.
-- I have used these for 500+ hours, and noticed they have greatly improved, providing better bass response and are much more detailed, and find it very difficult to listen to any other headphones (became accustomed, and attached, to the 650's signature)

**If used not amplified, and plugged into an ipod (or most mp3 players), they will sound very quiet, even at highest volume settings. They will also have poor bass response. This is why "burn-in" and amplification is highly recommended. After proper burn-in time, they do open up a lot, even if they are not amplified.

5 out of 5 eggsSuperior Unbeatable

Pros: I am chuckling as I read the other reviews. I have been an audio junkie for 40 years. I have never heard anything as good as these anywhere near the price range. You can wear these for hours in comfort, too.

Cons: Not really designed for computer junkies. These full range headphones demand more power than most computers put out.

Other Thoughts: If anyone thinks these sound bad, it is probably the device driving them. Don't buy these unless you have something with sufficient power. The headphone jack on my home stereo works great, but something like a laptop will need a headphone amplifier.

5 out of 5 eggsGreat SOUND!

Pros: this headphones sound quality is unmatched, i matched this headphones with the FiiO E17 which is also hard to get your hands on, and the sound is very clear and pleasing. Now i can see why this headphones got such a high review, it is worth every penny.

Cons: Price, Newegg has it at retail, dont know why its at this price, they need to give on the price a little!
- expensive
- tight on head, its brand new, i have to wear it in.

5 out of 5 eggsVery Very Good

Pros: Very natural headphone. Extremely comfertable. Everything positive about this headphone that is stated in previous reviews is true. I use these mostly on my computer and have a creative x-fi titanium sound card, and there is no need for an amp if you have a good sound card with you`re pc. Don't use equalizer imo. Amp is always nice but if you are going to be using these mostly on you`re computer just pair it up with a top of the line sound card. You wont regret it.

Cons: The price is too high. Try and get the best deal you can and it will be worth it.

Other Thoughts: Really comfertable. You can wear them for as long as you want (12 + hours) and you wont get a headace or have the urge to take them off. They are really that comfertable. Nice to have top of the line headphones. I use these at home and cant wait to go home to throw these on and listen to music and games. Wish I could hear all sound like I hear sound through these headphones, if that makes sense. As good as headphones get without getting insanely expensive.
