Sennheiser HD560S Review (Headphone)

[metal1500]

EQing per song sounds a bit like the problem is not the headphone tuning, but the mix and master differences of your music

metal is like that, theres the amazing sound disk that i can listen even without EQ (dcc gold or audio fidelity disc, toshiba cp32);
theres the poorly mastered album - compressed sound (megadeth rust in peace DR 6!), iron maiden piece of mind or metallica and justice for all - there's no bass.
and the ear bleeding ones - manowar Into Glory Ride - lol

Yeah, metal and hard rock used to be pretty wild sonically It still can be, but modern technology and somewhat established recording techniques - after a couple of decades of ear piercing treble peaks - help a lot

Good morning everyone!

I am a new user of this forum and a new and happy owner of these headphones.

Headphones that I only use late in the evening to play PS5 games and watch movies. I do not have an experienced ear, but I am already very very satisfied (I am coming from Beyerdynamic 770 Pro).

Granted that I connect them to the headphone output of my Denon x3800h receiver, which has a graphic equalizer to set, can you recommend the best ones to apply for these headphones?

The settings allow me to make changes to the following values:
63 Hz / 125 Hz / 250 Hz / 500 Hz / 1 kHz / 2 kHz / 4 kHz / 8 kHz / 16 kHz

I hope you can help me, thank you!

Hi, are you sure you haven't got a 31Hz filter too, I reckon you do? Also, did you buy the headphone new recently or did you buy a used one, I ask because if you bought it new recently then you have the New Version HD560s? If you answer yes to the previous two questions then try the following EQ I just did which is basically HD560s New Version EQ'd to Harman Curve using a standard 10 band Graphic Equaliser:

The EQ can't totally sort out all the peaks and troughs because the bands aren't located in the perfect places, but it does allow you to get the range from 30-3500Hz pretty much spot on Harman Curve, whilst also bringing 6000-8000Hz a little closer. I dialed in just a tiny tad more bass than Harman (less than 1dB more) just because we can't EQ down that 5kHz peak so I figured it might help balance it a tad, but that tiny increased bass above Harman is hardly worth mentioning.

why equalizer apo gives a clipping warning (RED) if gain is only negative. should i add a preamp? with oratory settings the peak is 0dB but it's not red (with oratory preamp).

Maybe the peak gain is in the positive by less than 0.05dB and rounded down to 0.0dB. I am not an expert on EQ artefacts but that is my guess. Maybe give it like 0.1dB of negative gain (somewhere in the software).

Adding a preamp is always recommended to avoid triggering CAudioLimiter:

Ending the Windows Audio Quality Debate

A debate has been long raging in the audio community that Windows isn't fit for use in a high resolution audio system. Sceptics counterargued that bits are bits and Windows audio degradations are a figment of an over-active audiophile imagination. I decided to investigate this as I kept...

I think EQApo marking 0.0dB Peak gain as red in your case may not actually indicate clipping. Is it still red when you disable the Peaking filter?

In any case, you can check for actual clipping using REW and Audacity Wasapi Loopback.

if i disable the filter it's not red

Maybe the peak gain is in the positive by less than 0.05dB and rounded down to 0.0dB. I am not an expert on EQ artefacts but that is my guess. Maybe give it like 0.1dB of negative gain (somewhere in the software).

with -0.1dB of preamp it's not red too

Hello! As you can see from the attached photo, you can only edit 9 bands. The headphones were bought new on Amazon 4 days ago. So can you confirm that I need to use the settings you forwarded to me above? Thank you!

I’d be more concerned about the output impedance of your receiver than EQing the headphone. It’s probably very high and is likely giving you some mid-bass bloat.

Ah, you really do only have the 9 bands then. In that case try the following EQ which is just using your 9 bands, and I increased the 60Hz area a bit more above Harman bass level because now we can't boost 30Hz and we still have that peak at 5kHz that we can't do anything about, so I just eyeballed that increased bass level for better tonal balance.

From @solderdude's website he's showing that the green line in following graph is 120ohm output impedance. @Punkcouple what's your output impedance of your Denon?

@Robbo99999 Is this data okay?

 

[solderdude]

Unfortunately Amir did not measured the headphone out on it.
Usually the headphone out is an afterthought on this kind of devices.
Either it is low power and near 0 ohm or they use the speaker-out of the main channels through some resistors.
In the latter case the output resistance could be anything between 50ohm and 300ohm.
Only measurements can tell.

Worst case scenario you simply dial down the bass a couple of dB. Bass should be adjusted to taste anyway so I would not worry about this too much.
Exact EQ based on a measurement is a bit silly anyway as your HD560S will differ a bit from the one that was tested (production spread) and your head/ears will differ from the test fixture anyway.

That doesn't tell us what we need to know re the headphone jack. I would say try the latest EQ I posted to you, and see what you think to it. If the bass is too much then reduce both the 63Hz filter and 125Hz filter by the same amount, so if bass is too much then lower them both by 1dB and try again. I mention the 125Hz filter because both the 63Hz and 125Hz filter cover off the main influence of increased bass through higher impedance as seen in solderdude's graph that I posted up, so theoretically if it's too bassy because of your output impedance then lowering both the 63Hz and 125Hz filter by the same amount could offset that as well as just generally tune the bass level to your own preference. If you're finding you're needing to lower the bass a lot then you're probably not a fan of Harman Curve bass in which case you should stop focussing on the 125Hz filter and lower the 63Hz filter more than the 125Hz filter. But lowering the 63Hz filter and 125Hz filter together by the same amount would roughly counteract any issue associated with higher output impedance. A 120ohm output impedance looks like it only increases those filters by about 2dB but I don't know what a 300ohm output impedance would do in terms of higher bass levels. I guess overall to keep it simple you can just try the EQ and adjust the bass to taste if you don't like how it is with the EQ.

Only £99 at Amazon UK right now, they've not been lower on Amazon I don't think!

Ha, I know you don't mean that because you've already had 3yrs of HD560s enjoyment!
