šŸ”¶ Sennheiser HD650

Sold my 600’s…After a few months I bought a set of the 650’s…had to see if they were really any better or different.

The 650’s are my low end /low cost gold standard for all things headphone related.

Having the TOTL cans, amps and dac, yes these are not at that level, but for the cost and design they are absolutely superb…

The other day I put them on and connected to a Schiit Jot1 (and I have a jot 2) with the SE jack and low gain…played some random low pedal organ music and was floored at the bass (bass extension) that these 650s presented…yes maybe not the most accurate etc but the freq response was indeed very very good do these dynamic drivers…

Hey All,
My 6XX finally arrived yesterday (actually, the deliverer wouldn’t drop them off as I owed import fees and so I had to walk for to the post office— Totally worth it!) Having lived with the peakiness of my AKG K701 cans for the last few months, I was forever playing with eq to make them listenable, and found them incredibly fatiguing, especially with older material. These are far more relaxed and forgiving - just smooth like butter in comparison. Not as (artificially) wide, which I suspect is down to the weird tuning of the AKG, but that always led to far too much stereo separation and was especially disorienting on older tracks. Even my wife, who tolerates this hobby but has 0 interest, was impressed when she put them on, and similarly noted how much more pleasing they sound! Well worth the drop price, for sure. I’ve tried EQ (crinkle, etc.) as well, but actually prefer their out of the box tuning, which is just fun and brings a nice mid -forwardness and roundness to the sound.
Now to hear how I need bottlehead, lol!

Out of curiosity, how are these headphones considered neutral? To me, they are like sitting down at a nice, warm fire in a wood cabin - cozy, not overly spacious by any stretch, rolled off treble that is still accurate, but a definite mid bump and 0 harshness… I can get why some people would find them less immediately exciting, and even call them veiled, but damn. They kinda sneak up on me and, before I know it, I’m several songs in, just grooving - or at least that is my experience…
I wouldn’t want them to be my only cans, but pour me a scotch after a hard day, throw these on, and I can just melt into the couch without a care in the goddamned world. Anyone have similar experiences?
Or are you thinking, 'Oh, wait until you hear x, ā€˜cus I had that experience and then heard…’?
Or, ā€˜You are listening to them on JDS element II, but wait until…’?

If anyone’s interested I just did a big comparison post of the 6XX vs. the Sundara over at headphones.com: Sennheiser HD 6xx vs. Hifiman Sundara SHOWDOWN REVIEW - General Headphone Discussion - The HEADPHONE Community

Nice one, thanks for sharing. If u can, at some point try the HD6XX again on a good tube amp

Which one would you recommend?

Ideally I would really skip the DarkVoice/Little Dot (only the budgetary, this brand has some high end tube amps) level of stuff and aim for something like the Bottlehead Crack with Speedball or sth equivalent (to name a few: Feliks Echo, Hagerman Tuba, Tor Audio Roger, Shortest Way SW51+), but I personally believe the Crack has the best synergy with the Senns at this price range

I think most people (including myself) consider them too warm to call neutral. The HD600 is closer to neutral.

I’ve got this cable from Lunashops. I love it.

I want to make sure I understand this. The Crack is an amp that you assemble yourself? Looking at the page, it’s not clear to me what exactly this involves–is it mostly soldering wires?

I understand how some people might like this sort of thing, but I don’t really understand why they don’t sell a pre-assembled version and charge more money for it. If it’s as good as you say it is, there’s surely people who might want it who don’t feel comfortable assembling their own electronics.

You glue 4 pieces of wood together. Solder a bunch of stuff and screw a few things.

Their entire business model is DIY kits.

You can buy a built one used or professionally assembled. They range from $500 to $800.

Usually people do, I didn’t I bought mine pre owned. You can find used units pretty often.

There are a few pre built ones online too. Check out the crack thread and there would be some links to people who build them and sell them. They do a nice job too.

Great review!

Was curious to get your thoughts on how 6XXs perform with say…a JDS Labs Element 2? Figured it’s a slight step up from the atom, which I think you mentioned was okay with these headphones :slightly_smiling_face:

I’m sure it will be fine. Probably won’t be as good as a tube, but the Element II shouldn’t hold it back much.

Not sure if anyone posted this video yet, but this is fascinating:

The 6XX and the 650 don’t sound the same (according to the video)

From my experience they don’t sound the same, but this being said, I’ve only heard older 650s vs 6xx, perhaps the newer 650 would be more in line with the newer 6xx, not sure (given different location of manufacture and different tooling iirc). They are still pretty close either way where imo it’s still pretty clearly a 650 either way. When doing comparisons like this, you really want to account for things like wear on pads (pretty important), the amount of time on the drivers (smaller importance), and also the age and time of manufacture to account for both batch variation and if you go old enough almost silent revisions/slight changes in design (also important), because those can definitely skew results. I mean you might even get multiple pairs of a single headphone and have them sound different between each other a bit, depends on the level of current quality control (although this is less an issue for sennheiser and more for other brands lol). Anyways, the 6xx is still a great deal, but if given the chance between an older 650 vs a 6xx I’d go 650. But if you aren’t a diehard fan that wants to get everything out of them as possible, the 6xx is frankly a better value and I don’t think the differences are going to matter that much in the end for most, they are again more similar than not, still pretty damn close most of the time
