HE-5..initial musings - Page 42

post #616 of 1668
For those of you who are hearing this edginess, midrange peak thing that exist in some of the HE5, could you humour me and try placing a small round label in the very center of the driver which faces the ear.

this sort of thing..



You can vary the size, I suspect that it will help with the problem.

Labels for centrifuge tubes, oh what fun.

Could the fabric lining the inside affect sibilance?

I tried large and small, thick and thin materials (my daughters foam stickers for instance)- all had no effect.

After 3 hours of burnin I decided to take a listen. I was burning them in using Bach organ music. I'm hearing crackling in both ears during loud passages. This is definitely not in the recording. I'm using my Marantz SR6003 receiver. There is NO crackling with either my SR225 or AKG701 at much higher volumes. Is it possible that the receiver is having problems driving the HE-5?!?

I just tried it through a different source into my Sonic Frontiers Line 3SE phone out.Same crackling sound!

Any suggestions?

Sounds like your receiver is having problems driving the HE-5, yes - I had the same issue at RMAF running it through my tube amp.

Are the phones now damaged by any chance?

Have any aftermarket cables been developed for the HE-5 and are they available now? I know that Drew from Moon Audio is working on one but I don't think it's ready yet. Does anyone know if Alex makes one that is available now?

My cable is clear and the wire looks like it is probably silver coated copper or less likely pure silver. The picture on the Head Direct website shows a black wire. What color is the cover on your wire, clear or black? There were some complaints about the wire being noisy but I don't have any problems with microphonics. Are there 2 versions of wire?

Try APureSound - Where The Music Is Always Pure - APS Audio LLC. They gave me a quote.

I receivedd my HE-5s yesterday. The included clear cables are not microphonic at all.

Female vocals definitely have a sharp "sss" which to me is sibilance and hard to listen long to (sounds unnatural). I find myself turning the volume down. It gets less tolerable at higher volume. People complain about the 325is treble but I could run those at ear-splitting levels without the sharpness I get through the HE-5 (HE-5 beats the 325is in about every other way though). I have tried both the stock cable and my DIY balanced one with the same results. My D7000's have more fun bass but have a smaller sound compared to the HE-5 (less air and separation, detail). That said, they don't have the etch.
This was unexpected as some here heard zero sibilance (except sachu, who sold his).
I will give it more time (100 hours at least).
ITs a shame you are hearing this. Otherwise it is close to being a perfect headphone. For me it was save for that sibilance. Never doubted what i heard but strangely it makes me feel good to know that others do hear it too. dBel84 was right, if you hear it, then you hear it. Nothing more to it, so don't second guess yourself. And we tried the phone on at least 3 amplifiers and 3 different sources and still arrived at the same result.
So, Kabeer's bullet points seem like highly plausible causes for the unfortunate slight sibilance found in some of the HE-5s.

I would try returning it for another HE-5 and see if it goes away. But, I know what you mean about not being able to live with that slight hump.
post #626 of 1668
Well it's quite pronounced on most albums, female vocals in particular. I would not call it slight on mine- more than the HD595's I had a while back.
I really trust some of the opinions put forth here and it makes me feel like there's something wrong with these. Skylab hears no sibilance and we have the same amp (though he has a difference DAC). My Ref-1 is anything but sibilant.
I am giving them 2 more days burn-in but I doubt it will change. If no change, these go back (or someone can buy them from me if wanted, balanced cable thrown in).
Another gripe is that the nuts inside the housing have become real wobbly from changing out the cable a few times so it's been hard to get a secure connection. There seems no way to get in there to tighten them. These really should be xlr type or mini jack.

I know, I too noticed it especially on female vocals and was oen of my first immediate impressions on another forum that i have posted here a few pages back.

shame about the jacks coming loose...yeah u know the courtse of action to take..return it for a refund or get another and keep your fingers crossed
post #628 of 1668
For those of you that are hearing sibilance, you may want to try burning them in for atleast 100 hrs. Skylab stated he did not evaluate his pair until they had burned in for 100 hrs. Since you have a 30 day return policy what do you have to lose. If I had formed my opinion of the HD800 based on what I heard in the first 3-4 days of burn in, I would have returned them because of sibilance and a sharply etched treble response. The HD800 smoothed out after 300-400 hrs. Many did not properly burn in the 800 and I think that is why the opinions of the HD800 is very divided and it looks like people are jumping to conclusions of sibilance on the HE-5 now. 35 hours is not a lot of burn in time folks, give it some time. If after a couple of weeks of 24/7 burn-in it's still sibilant, then return it. That is my advice and that is what I plan to do.

orthos don't benefit from burn in as much traditional dynamics do..mine didn't change after the first 10-15 hours of playtime.

The cable itself takes more than 10-15 hours to burn-in. I'm sticking to my plan as stated previously.
