True enough!

Good thought, and I know what you mean. I do tend to hold the cable steady "back it up" while holding the nut with each partial turn which alleviates that problem except for the last half to full turn.  But yes, that could certainly play a role slightly, though I've mitigated most of the issue.

Yeah it does bug me how far they extend from the cup and have a habit of poking yourself in the shoulder with them if you put the headband forward on your head....it really iss a kind of sketchy design choice.

 

On the other hand I look at the friction-fit bipin plugs on HD650 and am reminded of how much I otherwise like the HFM SMC connectors wink_face.gif

Thanks !

 

The he400 really isn't in need nor does it benefit from modding. The velour pads are a sure thing. No pleathers needed at all IMO. The only favorable mod has been the grill mod done by our very own Jerg!! biggrin.gif

Have you messed with taking the grills off yet Matt? It does make a difference, those planars wish your head wasn't even there.

Other than the cables -

 

Has anyone tried modded grills using nothing but stretched fabric and perhaps thin metal in a crosshair shape to provide some structural support?

 

If no grill sounds best, it would seem that some stretched fabric could be a good route. Stiff enough, and it should take a bump.

Also, try sticking a finger under each cup and gently "unseal" the cups from your head, and observe the impact on the bass. I wonder if the effect could be created by creating a small gap in the pad somewhere.

Well, I tried to mod the grills but just ended up putting a big dent in the side of it. tongue.gif jk.

 

Seriously, I did take the grills off and it does improve the sound. I just don't have time for mod projects right now. Maybe over the thanksgiving break.

Iknow its a bit offtopic but..Does this mod also favor the he500 soundquality?
post #2423 of 17943

how does the he-400 sound compared to the he-4? ive got he-4's, and im curious. some say the 400 is an upgrade, others say its just a different sound signature

AFAIK there are two main differences, 1) they are significantly easier to drive, 2) they are more balanced-sounding and less "v"shaped. Oh they are also gonna be a bit heavier (but not as heavy as HE500 or 6).

How does the grill mod affect the bass?

It doesn't, not noticeably anyway. You and others wondering about the grill mod need to understand that all it does is it "opens up" the sound of the drivers, by reducing the backwaves caused by the restrictive stock grills, but that is the only real effect you will observe. Nothing will happen to the sound signature or particular sonic aspects. It'll just sound cleaner and more open.

Seems like there are no drawbacks then. Will definitely give it a try when I get mine. Expecting it next week.

Recently re-acquired the HE4, and I feel that they are actually more balanced than the HE400, as well as more detailed. However, the HE400 is fuller sounding with more bass.
