So why is this an issue with the 500's? Is it an issue with all Hifiman cans? I love the music they produce

but I don't know if I can live with buying more cables without assurance the problem ceases. I don't have

problems with any other cans and until I posted my problem I had not heard of it.

Why aren't the cans grounded from the amp? Anyway I am just frustrated.

Thanks

Its no issue with hifiman can..

I had almost all models and took two of them (on holiday) to probably warmest place in south europe (algarve-portugal) and even took the he300 to the beach at with 38 degrees celcius in the shadow and super dry atmosphere..and no static at all!

I still think u have to try my tips (a few post up) ..to check if u have some kind of malfunction or static discharge in ur system...

did u try out what i advised?,,, those are easy steps..and it will make u find out if its hardware or something else..

.i am almost sure its not cable issue..as u said u bought another one..and issue stayed And ur other phones dont have the problem so it must be something else...

the he500 does draw lots of current from ur amp, much more then ur other phones probably, so i think u should look into the amp or the power delivery to the amp...

Check my easy steps..and.if it wont help..then u can always try a GOOD conditioner (for instance the one i use)...one that works well and doesn't rob the music of its soul as many do, most of them clean the noise very well, but at the cost of musicality...

Good luck my friend

I have five HE500 cables two with shielding braids grounded to the plug and three with only insulated signal wire

With the "naked wire" cables the ear zap effect was a common occurrence , I believe it is a voltage potential being generated by the cable insulation rubbing on clothing/furniture . I have never heard any audible noise associated with the zap effect so I do not think the charge is transmitted via the wire or diaphragm or generated in equipment. My belief is that the voltage potential is transmitted as static over the outside of the cable into the magnet array frame where it jumps to you're ear .

With my two shielded cables any voltage potential flows to the shield and out through the amps ground .

I have NEVER experienced the ear zap with a shielded cable

None of my other headphones exhibit this effect shielded cable or not, it is peculiar to the HE500

Makes good sense. I remember reading about people getting static shocks from their HE-500s like 1/2-1 year ago or something. Never happened to me.

Sounds like a good explanation to me. Which shielded cables are you using or did you make them yourself?

 

Static is a big problem here in the Highveld which is very dry in the winter with humidity typically less than 15% and about 1500m above sea level so my ears get zapped pretty often and it would be great to fix that... I once accidentally nuked a $300 FPGA with an ill pointed finger on a prototype board. Definitely didn't win any popularity contests with that one. You'll also pick up some choice swear words when people walk into offices with aluminium door frames or handles here as they discharge the static they built up from walking on the carpeted floors. ZAP!

All my cables are home made , I was using moon audio black dragon but recently I switched to canare star quad

I think the climate here in South Australia is quite similar to South Africa , I have to keep one finger on the metal frame of the shopping trolley at the supermarket or I get a belt every few steps

Anyone know a good grill to use for the grill mod?

Office supplies shops sell document trays and rubbish bins made of mesh that's good to work with and cheap. Document trays are probably better because they're flat, but make sure you get sufficient unimpeded mesh (i.e. No reinforcement or ridges)to cut 2 circles out.

I tried my HE-500s with the Matrix Quattro amp last night. Running in balanced mode, the Quattro has excellent synergy with the HE-500s and it's only $300-400 so a bargain for quality, fully-balanced amplification. I wouldn't bother with it for single-ended operation, but it's a gem when running balanced.

Listening to my HE-500 now, using the stock (silver) braided cable.  Never had any issue with static electricity, based in Delhi where summer temps in my office (AC on) easily reach 36 centigrade, with a relative humidity of max. 20% during april-may.  Sounds strange but for the OP, a fixed ground line should do the trick (as well as perhaps extra insulation around the cables).

I am assuming you wear the velour earpads in that Delhi weather. A few years ago I was in Noida around the same time of the year and it was impossible to wear any pleather or leather pads without it getting soaked in sweat, especially outside.

Airco? Or huge fan? biggrin.gif

Indeed, am wearing the velours pads, dust-magnets though they are.  But the dry march-june heat is nothing, been here since 2008 (returning to Europe this summer though) and I've grown used to getting up before dawn and taking my first espresso (and until recently my first cigarette of the day) around daybreak when the temperature's a balmy 28 centigrade or so.  Monsoon is worse, reminds me of Houston on steroids, humidity wise.

 

Music tip of the day:  I've discovered some recordings of what is one of the finest violinists of the 20th century:  Georg Kulenkampff who along millions of others, had the misfortune of being professionally active in 1930's Germany.  His 1937 rendition of Schumann's violin concerto in D- (composed while Schumann was affected by tertiary syphilis, which influenced his sense of tempo but anyway...) with the Berliner Philarmoniker is absolutely breathtaking.  They have it on Presto classical, produced by the Japanese 'Kura' label and based on old 78 rpm recordings.  Recorded in mono, obviously.  And very much one of those recordings where you want to leave your HD-800 locked away due to all the artefacts.

Anything that is described as Houston on steroids is a level of humidity I do not want to experience, I recall walking through med center in july and I'm fairly certain fish could have lived on land that day.

I am going to attempt a diy cable, on the connector to the headphone the pos goes to the center,

where do you solder the ground? Anything else I should know or watch for? Thanks
