Static noise with headphones

[waterfall101]

I just got a new PX-S7000 and everything is great except when I connect headphones.

I have a nice new pair of Sennheiser HD599 headphones and they sound perfect when connected to a phone or computer, but when connected to the keyboard there is a certain static, hissing, buzzy noise that is very annoying. The noise is only triggered when certain notes on the keyboard are played. Some notes cause it and others don’t, so it must be related to the pitch frequency somehow. However, what’s even more strange is when I connect the headphones with the 6.3mm jack there are many more notes that cause the static than there are when connected with the 3.5mm jack.
 

I also tried it with a cheaper pair of headphones and although the sound quality is much worse, there are less notes that produce the static noise but it still happens on a few. 

Also, the Casio itself doesnt make any noises like this when playing from the built in speakers.

Does anyone have any ideas how I can solve this? Any advice would be much appreciated!

Is this happening only with grand piano tones?

It is happening on the grand pianos but also electric pianos and many other tones, but not ALL tones. For example it doesn’t seem to happen with a lot of brass and strings instrument tones

Very unusual.  Do you happen to have any external speakers you can patch the headphone output into?

I don’t have the proper cords for that at the moment

[Brad Saucier]

Did you purchase the piano from a local music store?  If so, I might talk to them about it, perhaps bring your headphones to try with a different floor model.

I've got some HD599s, bought a month ago, they sound lovely on my px-s6000, and that's via the 6.3mm connection, so

it doesn't seem normal at all. Make sure the headphone end of the cable is properly screwed in.

 

Maybe do a factory reset, to make sure the s/w isn't confused?

Tried the factory reset, no luck…

 

It really is so odd because if I plug the headphones into the piano and play music bluetooth through my phone, I can hear the fuzziness, but if I plug the headphones directly into my phone it sounds fine. 
 

I guess it is the fault of the Casio. So disappointing for such an expensive product.

[Brad Saucier]

Are you certain the plug is fully inserted into the keyboard?  Otherwise, it is difficult to pinpoint what is the issue from the forums.  I would contact the music dealer who sold it, or contact Casio support.  You definitely have support options to make it right.  

[Fancellu]

Well, looks like it should be returned. At the very least, reach out to whoever you got it from, see if they know of this issue and what they can do to remediate.

 

If it was a common issue many more people who be talking about it, sounds like you just got unlucky.

 

But it does point to maybe something missing from the QA process that let it sneak out

 

These things happen. Before the s6000, I had a StudioLogic Numa X Piano GT, like a tank, but had to return it, and it was a real pain to return.

 

I'm glad I did though, the px-s6000 was the right choice for me. 

 

If you have a dual TS to TRS cable you could try that on the line out at the back, for diagnostics at least

thanks everyone for the advice.
 

I went to my local Guitar Center to test out another S7000 and other headphones and learned a few things.

 

1. My Sennheiser’s came with a faulty 6.3mm cable

 

2. Even with a GOOD cable, all S7000’s have a faint hiss/crunch sound that intermittently sounds in the headphones when certain notes are played. Mostly on the grand piano tones.

 

I’m not sure if this is some frequency that only certain people can hear or if it’s just something I need to get used to. 
 

3. I tried the same headphones on other Yamaha’s and Roland’s around me and the sound was not there. It’s exclusive to this model.

 

I wonder if it is something related to the use of samples in their grand piano sounds instead of it being computer generated. It’s too bad because I much prefer the sampled tones.

[Brad Saucier]

You may be hearing some of the string resonance effects on the grand piano tones, especially if that's not there on other tones, but I wouldn't describe those sounds as hissing or crunching at all, so I'm not sure what to think. 

[Fancellu]

Well, I have a px-s6000, which is almost the same, and the same headphones, and hear no problems. Maybe it is your perception of it. 

 

Odd that you don't hear it on the speakers.

 

If you are saying that ALL s7000s do this on headphones, you'd have thought that more than one person would be reporting this.

 

What happens when you try other piano tones?

I only say that because it was the same on the one I tested in store so that’s two examples.

 

Some specific examples are
On the Privia HG, when I play the B4 loudly a few times I’ll hear a sort-of hard to describe hiss sound.

On the Privia NY, when I play C2 or C#2 loudly I can hear something like blowing wind or a crashing wave in the background.

 

Now that I know what listen for I actually do hear it on the speakers but it’s not as easy to notice as with headphones.

I also tried turning off all of the acoustic simulator options and fiddled with all of the tone modify options in the casio music editor but nothing removed these noises.

 

As soon as I get my hands on a new USB drive I’m gonna save a recording and see if I can hear it on my computer.

 

My best guess is that it’s just part of the samples but if no one else hears it, it just doesn’t make any sense!

 

Edit: Also I can hear the noises better when I turn the Brilliance Up!

Please do, and perhaps share the recording here.

I posted some here, I think you can hear the noise best in Note 1. It almost sounds like a forceful exhale or something. Is it just me hearing it?

 

 

[Brad Saucier]

I don't hear anything unusual for keys and piano strings that are struck pretty hard/aggressively.  How does it sound when you normally play a mellow piece of music?   

 

You may like to find headphones with different response characteristics.  Some headphones emphasize bass or treble more than others.  Some have a flatter response with a good balance between bass and treble.  For reference, I'm using an old pair of Sony MDR-V150 headphones to listen to your demos.

[Fancellu]

You know the saying, wherever you go, there you are. 

 

I'd say it is your perceptions of the sound.

 

See if PianoTeq is more to your liking, they have a demo mode. See if you hear the same artefacts. Remember, with PTQ, it isn't sampled, it is modelled.

I tried three different sound systems, the built-in speakers on my iMac, a set of Beats headphones, and my studio monitors. The only thing I might have heard was in the start of third one it almost sounds like a second strike. But other than that, they all sound pretty normal to me.

I think I'm having the exact same issue, it  was much worse on my Marshall headphone. I went to the store to test the Marshall headphone on the sample PX-S7000, it was the same. The staff let me tested a few other headphones, it sounded better so I thought it was just some incompatibility issue. ThenI got Sennheiser HD599 hoping the hissing sound would be gone, but it's still there just less noticeable. 

It's really troubling me because this is an expensive product.

How did you resolve it?
