The HD650 Experience
« on: July 14, 2010, 08:18:49 PM »
These were my initial impressions of the HD650 back  on: April 13, 2010, 05:03:57 PM

Well, Doc Egay "discovered" that I now have Azathoth's HD650 in my possession. I was going to keep it a secret for "Ewok" but since it's out of the bag I might as well post my thoughts.

I submitted a review to Headphone Solutions with the hope of getting an HD800 in return. :D I am pretty confident in my writing skills so next meet I will bring an HD800 for everyone to enjoy.  8)

Ok back to the topic.

The HD650s are pretty much what I was looking for. Basically a smoother, less-fatiguing version of the DT770-250. In fact, with these, I am thinking of selling my Beyers, as these take their spot quite nicely. They aren't perfect replacements; the Beyers have tighter and warmer low end which I will miss, but I guess I can go and check out other bass monster cans now like the Denon 2ks or Ultrasones (if I can find them). The HD650 fills the role of the DT770 for me.

What I really like about the HD650 is how smooth and creamy it is. I can't help but compare it to eating some really fancy chocolate and slurping a nice, frothy, creamy milk shake or frapp. As I said in the review I submitted to Headphone Solutions:

"So when I came across the HD650, I felt that I had been moving from various cheap foil-wrapped chocolates to a really luscious chocolate fondue served for dessert at a classy restaurant. Compared to a lot of other garden variety headphones I had been listening to, the HD650 was something special. Listening to it felt like swimming in a vast ocean of liquid dark chocolate. The HD650 at heart is a dark-sounding headphone, with a muted treble response and a very rich, oozing overflow of warm, enveloping bass."

In many ways, I would compare the HD650 to the Senn IE8. These are the only two Sennheisers I have heard that I really enjoyed, by the way. Wasn't a big fan of all the other models I tried and tested (and owned).

The HD650 is 300ohm but I didn't find it particularly hard to drive. It sounds *great* out of my PC's Auzentech Prelude going to my HeadAmp 4. It drives really well with LD Mk II as well, and sounds absolutely fantastic out of the Marantz 1090 (who said integrated stereo amps are no good as headphone amps!).

Perhaps surprising, it sounds surprisingly decent out of the iPod Nano -> LOD -> Petite combo. The resulting portable chain was rather unportable thanks to the HD650's big fat cables and my needing to use a converter from 1/4 to 1/8 plug, but the resulting sound was very listenable and quite fun.

It actually seems I have been enjoying hard-to-drive phones portably out of not-so-ideal sources lately. I guess this is good for now, when I get to hear what a really beefy desktop setup can do I will probably change my mind later.

But anyway I enjoyed taking these to the office (where some of my headphone friends also checked, and loved, them) and getting some weird looks at the huge "bug eyes" on my ears. :D

Overall I am very happy with these HD650s. They sound really clear, which was the first thing I noticed. These have the most clarity out of the headphones I currently have; it's on a whole different level. Tracks I have that usually sound muddy and dirty (Like Nino's "Sunny Side Hill" from the Mujin Wakusei Survive anime -- which has a dirty sounding bass and raunchy guitars) mysteriously gets cleaned up and pleasing to the ear with these headphones.

They are not revealing, I think that they fix up bad recordings somehow and make them nice to listen to. It's very strange.

They are also very relaxing and laidback. I get no fatigue *ever* listening to these. I could listen to them all day it seems. After adjusting the headband to my desired comfort level I can wear them all day as well.

Really, really good cans. Can't wait for the Mio's to arrive so I can do some ABing.

I get the feeling I'm going to be selling some of my other gear soon.

BTW, reading through that, it seems I still enjoy driving these out of not so powerful sources. I find myself really enjoying them through both Fiio E7 and NuForce uDAC. The sound they take on changes drastically though between the two.

posting my impressions on the hd 650

i wanted to do a comparison between these and the twin beyers, but i promised myself that i will give the hd 650 a week of solo listening... 'versus beyer' articles to come in the following days...

these are very comfortable cans, just a shade bit less than the beyer comfort. very easy to slip on and forget about them. theres a wee amount of clamping force around the skin next to the ears but its not bothersome. the open headphone style lets the air breathe out of the cups, perfect for hot humid environments like my dorm... excellent!

design is simply superb: these are great looking cans for me. black and gray colors are subtle and easy to the eyes. the marble like finish on the gimbal-like area and the headband is kinda sleek. i really like the look! these are cans that can be appreciated off the ears

cable is detachable, and kinda long for my taste (but better long than short). plug looks tough and solid enough to endure years of abuse. box looks as if it can double as storage bin to keep away dorm food from rodents and roaches. might try that in the future...

to the sound and meat of the matter. at first listen, i wasn't as floored with these as compared to when i first heard the 600 ohm beyer dt880. i think the 880 spoiled my ears and mind for so long, preventing me from appreciating the resolving potential of the hd 650. that was the reason why i wanted to spend time with the hd 650 alone. i just wanted to be impressed...

using the c-2c (wow this is just like Insyte's setup before!), i can hear detail and nuances slightly less than what the dt880 can resolve. its a very small difference really. c-2c can drive these cans, but the sound came out as disappointingly dull for some reason. switched genres to determine what music the hd 650 was great for, but i could not get these cans to excite me as much as the beyers do. this was when i decided to use the amp with tubes: little dot mkii. honestly i was expecting a big letdown because most of my gear had better sound coming out of the c-2c...

the tube amp. the lowly mkii tube amp. who would have thought... i did not. and the sound was alive in my ears in so sudden a moment! everything was airier, so much cleaner. the first word that came to my mind was: 'decongested'. tried rock, classical, some utada and john mayer, plus a bit of OPM true faith... it wasn't a fluke! the highs were effortlessly reached, and very beautifully too. how the heck did i even think of comparing these to the ie8? these are entirely wonderful sounding cans worthy of the label: flagship!

well, former flagship

kenny g. is stunning on the hd 650. never heard his greatest hits album portrayed as so vivid, so life-like, so alive! the thought that was running in my mind was that the senn engineers who designed this didn't aim for critical music reproduction but for sheer audio enjoyment! damn they are good!

my verdict on sound: life-like. highs extend very well without any hint of sibilance. bass is ample and better in quantity dt880-wise, but not as tight as i would have wanted, but who cares... everything else sounds so good! vocals are up there with the highs - inviting, hypnotic... soundstage is great, just a bit less than what the beyer can project, ample enough to give each instrument it's own space. acoustic guitar sound is rendered so well its creepy...

these cans are brilliant!

one gripe is that to achieve the total enjoyment effect, i have to turn up the volume...

maybe i can find a better amp for these in the future...

YMMV!

i would agree bro Erwin that these cans are a bit easier to drive. hooked to the mkII with dialed up gain (10) as per Azathoth's suggestion, the bass improved in quantity. it's kinda surprising how the sound is so good out of the entry level amp while the beyer's won't even sound half as good with the setup...

mkII as preamp to c-2c yields even better results: sweeter vocals with tight and plentiful bass as i turn up the c-2c's volume knob. the slightly loose bass is gone now :)

I've noted that the HD650 is a very forgiving headphone, both to amps and to source material. It works well with such a wide variety of amps and manages to sound good and different with each of them! Really nice. They are one of my favorite cans ever.

@Mochan, pls update with your impression vs K701 :)
@Maruzen, very insightful review...
@Mochan/Maruzen, I wonder how would it sound with the Dared MP5.

Wish I still had a MkII to compare. But sure I'll post HD650 + MP5 stock Shuanguang Tubes later when I get home. I'll also import my Mios thread here and bring to Head-philes one of Head-Fi's most enduring institutions: K701 vs. HD650!

I really liked the HD650's when I had them - just about the perfect jazz can as its signature really invoked that smoky club vibe. Don, for the lush Senn sound that you want this really has it in spades. Over time though I didn't like how some metal sounded like it was held back - of course due to my own noobness of not amping them properly, and having neither the time nor patience to upgrade the stock cables.  ;D

I think the hd250s that you got for me are even worse than the 650s when it comes to amping. It really transforms from thin to bold and dynamic when plugged into my audiolab. Galing talaga. I'm still impressed at what I got especially for the price.

Seconded. And if the source has a decent analog stage, they don't need an amp at all. With a great analog stage they sound even better than with an  amp.   :)

thanks! the hd650 was a recent acquisition. i felt the need for a comparison since it was the bass output between the dt990 and hd650 that was very catchy on first listen, and they had much more in common than the hd650 vs dt880 :)

maybe you could do a hd800 vs. hd650 comparison? :)
