HiFiman HE-500 (HE as in High End) Proving to be an enjoyable experience in listening. . - Page 895

I think if you've got a good speaker amp that works well with a particular can like the HE500 then it could take spending many factors more to get an improvement so a speaker amp could be more than sufficient.

I'm looking for an upgrade to my mini-x and Topping TP60 but I don't think I will be able to upgrade without spending more than $1k based on what I've read. I could be wrong

IMO/E, you are not wrong all the way up to $800.  :p

Also found this to be the case with many many amplifiers, which is why I've sold many amplifiers and kept the A-100 for ortho headphones.

I recently purchase a used pair of He500's and really like them. They came with the original

cable which I didn't like. I experienced a kind of a shock when I put them on and I thought it

was the cable, purchased another cable, same thing. So I redid my ground , actually installed a

dedicated ground with a 10' brass clad post put in the ground and installed a hospital grade

plug with a dedicated ground. Same problem, used them with my other amp same problem

although not a bad with either once the ground was addressed. I have other cans no problem,

help, what could be the problem??? Thanks

Do u have same thing when connected to a portable rig on batteries? Like ur mobile/tablet/mp3 player?

First try that out..buy a cheap adapter for it...sound will probably be shiity..but at least u will know for sure if its ur headphones or not...and if its not..then it could be ur amp being the bottleneck..maybe he is somehow clipping or switching into protection mode? So try another amp also...and if ur sure its nothing of that all..then:

i would advice to buy a Blue Circle Audio PLC thingee FX or the sillycone filter to clean up ur powergrid.....it did wonders with my rig! Check youtube out to see what it does wink.gif and they are very affordable as they dont come in a flashy case wink.gif but i put that stuff behind my rack anyway..i dont care biggrin.gif

I also had this problem

I believe it is static pick up from the cable , it is not coming from you're source

I built a shielded cable with Moon Audio Black Dragon cable and the problem disappeared

Any shielded cable like Mogami or Canare would also work

thanks, I'll give it a try.

Or humidify the air. Static gone, if that is what it is, which I would guess it is. Never had this problem with mine but I have tended to live in environments with some humidity.

Never mind static with the cable. Here with winter approaching the air is drying out again and if I move on my seat, which generates static, my ears get electrocuted from static jumping to the headphone diaphragm. Not fun zapping your ears! :basshead:

Ouch!! Sounds like you need a dedicated earth lead for your HE-500s

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!
