the measurement on the graph was done into which load? that could potentially make a big difference(although unlikely for a 300ohm headphone).
on the other hand, louder low end doesn't mean better driven or better source in any way. for example a 120ohm amp will create a bigger bass bump on the 650, but it can hardly be seen as objective improvement.

my guess is that different feedback about the mojo may simply come from people having a different reference sound. I often read about perfectly fine DACs or amps perceived as bright or sterile by some users. as the devices in question are factually not anything but very flat and good into the load discussed, I assume the person is just used to a warmer or less linear sound, and as a result finds anything else bright or boring.
it's the same as someone judging a hd600 when used to a 650 vs another guy used to a hd800. with a shift in reference, where we're standing also shifts.

Thanks a ton guys for the recommendations on amplifiers. I am researching your recommendations and will let you know how it shakes out for me.

Fellow HD650 owners could you test something for me? Horizon Zero Dawn Original Soundtrack, load up disc 3 track 17 Song to the Sun - Dawning. At 2:09 onward (warning loud) are your HD650s distorting? For me it sounds like peaking, like when a microphone red lines. Its not the track itself other headphones I own aren't doing this (while others are).

I think all three Songs to the Sun are going to enter my battery of test tracks. They really put a pair of headphones through their paces.

There's no distortion but there is some pronounced sibilance and that's probably what you're hearing.

What the hell? No comments in ages! Has everyone deserted?

The new site layout has drastically decreased the number of posts in the threads I follow, including this one. Seems allot of folks are still having issues with navigation, especially on Mobile.

I cannot use the site on my mobile phone now

What is a good case for transporting my HD650s back and forth to work everyday without unplugging the cable? I don't want to wear out the contact springs in the drivers, so I want to leave the cable plugged in. I can wear them at work but prefer not to leave them there.

Whatever you decide to connect, a connecting lead to lengthen it at home is cheap, unless you buy boutique wire!!

Something like this ....

It fits well enough but the zip broke a while ago. Still pretty useful though.

 

[HungryPanda]

I have the exact same case, works a treat

 

[Letmebefrank]

I might go with a Pelican 1400, should fit in there with room to spare without having to collapse the arms or take the cable off.

Looking for advice on a good tube desktop amp up to $500.00 for my HD650. I appreciate the input!

Get a Graham Slee Solo II. It's tube-like sound and one of the best matches with HD650!
AFAIK, Sennheiser often uses this amp to test their headphones

Anyone tried the Customcans modded HD650? Worth it?
