Sennheiser HD650 & Massdrop HD6XX Impressions Thread

Well, when HD650 launched back in like 2005 it was 800$. Guess the accessories have not kept up with the price reduction. Before the HD6xx it was common for HD650's to sell for ~350-400$ used.

You must be living in some very expensive part of the world.

According to CNET, the US MRSP for the the HD650 back in early 2006 was US$650/-.

I always thought that the highest retail price when the HD650 was released was $500, but looking at the old Headphones.com page, they displayed two prices. One was a price they referred to as 'list price' of $550 and the other was 'our price' or the website's price of $500.

That should be the current price points for MSRP as far as I have seen.

Note the CNET article from April 2006 and their stated MSRP here:

Addendum:

I believe you are correct. :thumbsup:

There's a 2004 article and specifically states that the HD650 were US$499/- headphones.

I got some 660S recently and I like them, it made me think "hmm" maybe I should try a 6xx / 650 with a powerful amp, I read a lot about headphones and I have probably read at least 10000000 times that the 650 scales very well with amps, so I am a bit interested if the 650 with a good amp would be closer to the 660S, or possibly better, rather than what I remember of the 650, which is that it was bit slow.. at the time I was using a Xonar STX, possibly with a better amp like a lot of people say it would be comparable or possibly better than the 660S.

With 650 I couldnt get the bass as tight and fast as 660 no matter how much i spent on an amplifier. 650 is much better suited for acoustic and jazz sounds amazing, 660 sounds exceptional with rock, metal, pop, electronic.

Is the 660 a nice dark headphone too? That’s what I love about the 650s. That honey drippin filter.

No it isn’t. It has a sound signature very close to HD600 but with a tad larger soundstage.

The HD660S is not as dark as the HD650’s. The HD660S’s has the new 150 Ohm driver and it’s not as smooth sounding as HD650’s. As matter of fact I find the new HD660S’s driver to be grainy sounding especially in the treble. When I had them I tried everything to make them sound better and remove some of that grain in the treble to no avail. I sold the HD660S’s and repurchased the HD650’s and they are better sounding to my ears. I also have the Loki to were I can add some subbass to the HD650’s and some excitement to midrange as well. They take EQ very well. I’m enjoying the HD650’s a lot more this time around

I found the 660S to be boring even tho it’s not veiled like stock 650. Frankly I prefer an EQ’ed 650 over 660S.

Added half a notch on the low end and highs. Wanted to retain some of the thick sound of the 650 :)

Problem I have is the upper-mids cut. It's not natural, it's blunts the sound and that 5k peak creates further unnatural-ness. I don't like distant sounding upper-mids

If 600/650/6XX didn't exist, I'd may like the 660S, but that isn't the case is it?

Listening to the HD650's out of the Burson Bang amp with Hifiman's HE-Adapter and the Burson Fun as a pre-amp. I'm also using the Shiit Loki to add some subbass and a little treble with the Burson Conductor Air as the DAC. I've never heard the HD650's sound so dynamic, alive and musical.

I liked the sound of Sonarwork's EQ but their software isn't a good long-term solution because basically once their servers go down you won't be able to activate the plugin license (even if you hack it, the generic 3dB presets aren't actually embedded in the dll, it downloads them from a server encrypted with your license key, so you can't share them with others). Also, I run Linux and while it's possible to use VSTs there with the magic of dssi-vst, it'd be nice to have some FLOSS alternative.

I've found EQ10Q which is a nice parametric EQ and applied this harman curve skipping filters 5 and 10:

I connected it to my music players with Jack and I find the sound very nice.

Here are my config files: https://www.mediafire.com/file/8e71aacl6f8e767/eq.7z
EQ10Q_Stereo_hd650_harman.preset.lv2 folder should go under ~/.lv2/ - it's the EQ's file.
eq10q.xml patchbay file can be placed anywhere and it's to be loaded via qjackctl
I've assigned this script to a key combo that starts everything for me:
Code:
#!/bin/bash

Xvfb :1 -screen 0 1280x720x24 &
DISPLAY=:1.0 jalv.gtk --load '/home/eimis/.lv2/EQ10Q_Stereo_hd650_harman.preset.lv2' http://eq10q.sourceforge.net/eq/eq10qs &

qjackctl -s

killall jalv.gtk Xvfb jackd
Remove the Xvfb call and DISPLAY=:1.0 to unhide the EQ window.
