As we all know there's a global problem with G750 models regarding hissing static noise while headphones are connected to laptop. I browsed the forum and found no reference that ASUS even knows about the problem and is doing something about it.
Just look at the amount of complaint threads on the ROG forum regarding this issue:

How much more are people going to complain until ASUS addresses this issue? It's unacceptable that headphones are practically unusable with these EXPENSIVE laptops when even a 10$ MP3 player can handle headphones without making hissing background noises.
Can a Mod/Admin please confirm ASUS knows about the problem and is working on it?

YesNoYes-

I don't care if you don't have that problem. Did you see the amount of people that are complaining about it?
I don't have a gold Ferrari like people in Dubai is it worth mentioning? No.. so likewise your reply is irrelevant.
Reply if you have something useful to add not with useless comments.

With G750JX Sennheiser 570 headphones are fine (high impedance), but I hear static hiss with Beyerdynamic DT-660 (low impedance).. Beyerdynamic DT-660 is fine on my desktop computer with ASUS Xonar Essence STX (built in amp up to 600 Ohm).

So the issue is definitely not with my Beyerdynamic headphones.. It's kinda expensive if you have to buy several headphones to find ones that work with G750. Safest bet is to get bluetooth headphones or external audio card... or RMA your laptop.

My experience is as follows (clean win 8 install, latest drivers from Asus site). I have 2 sets of headphones:

1. SoundMagic PL30 in-ear headphones, 12 ohm impedance.
2. Beyerdynamic DT770 Pro, 80 ohm impedance.

Both exhibit no hiss/static on my Fiio E07K dac.

Using the G750JX's headphone jack, there is very pronounced hiss for the 12 ohm in-ear headphones. The Beyers are dead silent, much like using the dac. Note that there's no crackle/popping static, this is just a constant hiss reminiscent of cassette players from the 70s (yes, I used to have one :-) ).

I can only assume that the built-in amp is high-impedance friendly, but doesn't like low impedance headphones. Of course, this is just one person, you'd need a lot more samples to generalise.

This.

Ive got hiss on 16 ohm phones (ie 80) and no hiss on 40 ohm phones (hifiman he 400).

Its a high output impendance problem, it cant be solved with software afaik its a hardware problem.

Well "buy expensive headphones" is not a solution. I see the Admins/mods here reply to useless threads all the time, yet surprise surprise they are completely ignoring this issue. Either they were instructed to ignore on purpose because ASUS won't admit hardware ****-ups to save costs on repairing them and the criticism they'll receive or they are just ignorant and don't actually want to deal with real problems.
Believe me Realtek doesn't put out crappy soundcards. And it would take a hell of a lot of negligence from ASUS to install the sound card incorrectly. We don't know if it's a software or hardware issue- what we do know is that if ASUS gave it's customers actual support, the problem would be solved.
Last time I am buying anything Chinese/Taiwanese. I'll stick to Japanese/Korean/European/American.

ASUS, YOU ARE A SHAM.

Maybe i'll start sending out emails to laptop review sites explaining the lines on the screen, the flickering, the bad audio, the non existent support who don't even speak English (they use google translate) and all-round feel that this laptop won't last a year before it needs mending because of poor quality build. They should warn the public.

I have Bose headphones and get a slight hiss, I think it's because it's amplified.

Actually the amplifier is sort of good, not to my taste exactly but it does its job beyond any other laptops built in solution to date. I mean lightyear beyond anything anyone else is offering. I also said "use high impendance phones" not necessarily expensive ones. Why arent you complaining about not being able to be good at bf3 playing with the touchpad instead of a mouse? Same thing really.

The lines on atleast my screen are easily fixed, sure i could set everything exactly wrong to make it a problem but I prefer not having them...

Poor quality build? I dont even know what to say to that. Compared to what laptop? MSI? Clevo? I dont know any other brands offering the new geforces. I would choose the g750 if I found myself in a bet "wich laptop survives me throwing it out the window" between those.
Please explain this remark about build quality because I really dont understand.

Youre way out of line threatening to try to smear asus reputation when the g750s are better than anything else on the market, sure there are problems and they are not perfect but ITS BETTER THAN ANYTHING ELSE AND CHEAPER!

Wake up dude.

That amount of ppl should consider this link http://www.asus.com/support/.
I know Asus rep's are answering some of the questions in this forum, but nevertheless it's not a true supportforum, more a "user to user" forum.
So aksing for support here is just as irrelevant as any other reply here..

IMHO Asus Support sucks sorry but it's true. That is why I come here! At least you have people with real problems that can get alot better support here than going to Asus Support. I can't tell you how many times I have called them and they had no Idea what I was talking about. IMHO there are you can get better support than you can from Asus Support.

We are not deliberately ignoring this thread. Sorry I didn't get involved earlier. At the time you posted, I was really busy with life (outside the forums). Otherwise, I would have answered earlier.

As to the issue with the hissing, I am not able to solve that problem, but if it is an impedance issue, then it is a hardware issue.

I got a G750JX this Christmas and I'm not having any issues when I plug my ATH-M50 headphones in.

When I get a sec i'll forward this thread to our ASUS support reps and see if its a known issue or not.

You could not have it more wrong. This forum is the 'first line'. Most issues
are quickly resolved right here avoiding undue traffic @ 'official' support.
That is why 'here' is 'here'.

That is how it works so well. Real users of the same products, many of them experts and pros.
Saving the time of 'Support' for actual RMA's or repairs, meaning faster turn arounds. .c.

Hello,
We are several customers encoutering the same issue in France with the jack and headphone, we are trying to build a list of person, hoping that Asus will recognize they have made a mistake somewhere. I believe that the customer should not have to buy anything else to enjoy a normal sound. Asus should be really gracefull for all the customers who can afford an high impedance headphone, or those who decide to buy an external sounds card to solve this... It's quite sad in my point of view...
I apologize for my english,
All the best

You need to contact ASUS support for your location. ASUS employees here are N. American support only.

Same issue, depends on headphones.
new drivers cut off the noise / circuitry when vol is 0, muted or no audio being played which is better. As soon as a game is opened you can hear it again.

I have a bad earphone / headphone habbit, so can test a few different sets if it helps. As the issue is widespread, it sounds like its either bad drivers or hardware.

If it is hardware, I don't see how it was missed during all the QC / design testing. Anyone know what chipset is used or is it all a part of the customised GPU?

I just came here trying to find some answer as your forum is way more active than in France. I would be curious if YesNoYes find a solution to the problem, that would be great.

I'm not much of an audiophile, but couldn't hear any problems with my G750JW when I tried it.

Not really sure where this will go and how quickly it will move, but if possible, please let me know which headphones you have tried and what you did to hear the problem.

In case the problem does not occur on all the G750 units and only occurs on some or with certain configurations, it can be good to work with your local ASUS support or service center too, but we can try to work on it more here if you're interested. Thanks.

Edit 2/12/14: Sorry, should have probably mentioned I only tried 1 headset, so will need to get and try others. Post #32 by zalbard has a summary of some headphones I'd like to get and try (I'll probably only get one of the cheaper headphones though) at this thread http://rog.asus.com/forum/showthread.php?35545-What-headphones-do-you-use-with-your-g750/page4

Hi,
Thanks a lot cl-Albert for your help. I was waiting for a replacement laptop.
Unfortunately, I have plugged my headphone, and the pSSHHHHHH sounds is still there... :(
My config is a G750JX CV030H, with 3D screen. I think this reference is not available in US, but the amplificator of the audio jack is certainly the same...
I have the B&W P3 headphone, they have an impedance of 32ohm. I really like their sounds, well usually... For now, I cannot see any solution, without buying an extra component or asking money back... :(

Hi Loneone,

Thanks for your update.

fyi.
Tried some very old Sony 'in-ear' headphones and was able to catch the problem on my G750JW-BBI7N05 too as you may have expected, but with a different headphone, there was no problem.
Appears you already know that using different headphones may make a difference too, but this may not be an option for you.

Anyway, reported the problem on my end, but not sure what will happen or how quickly, so we may need to check for updates later.

I am also using G750JX-CV069P in the beginning when it was windows 8 and all old drivers i get high hissing noise in SteelSeries headphone (came with the laptop) then i upgraded to windows 8.1 and update the NVIDIA beta driver too, from that day the hissing noise dissappear, i am using SteelSeries, Shure, Sennheiser. and no hissing noise at all. Didnt updated any sound card driver yet

That is definitely a lot of folks with that problem. Hell I kinda wish I had that problem as opposed to the ones I have (you know, the kind that render my laptop almost unusable).

Yup my G750JX is speaker-only for now. Earbud from both samsung and apple phones are making this irritating white noise even when just plugged playing nothing.

Same here, Just bought the thing, (Asus G750JH) It came out of the box with this hiss, I upgraded to Win 8.1, then tried two updated Realtek drivers, no luck, even tried uninstalling the Realtek drivers and using the Windows drivers, still didn't solve the problem, I then tried the most recent Realtek driver (V6.0.1.7183) still didn't fix it.
I talked to Asus support, and they offered me a replacement system, before I sent mine away for replacement I went to a local store with a demo on a G750JX and plugged in a set of headphones sure enough theirs had the same problem.

This problem exists on

From my limited knowledge on the subject, it seems the built in amp either has improper shielding, or the amp has too high of an output impedance for most everyday headphones (or lacks the circuitry to modify the output impedance to suit the headphones its driving)

Eitherway, this seems to be a serious design problem, and is very annoying for people with low impedance headphones, has anyone solved it through software fixes?
