Hi Chris. Been thinking about you. Well, it might be a good thing really!! My hearing tails off at 15khz. All the other stuff just baffles me. I'm deaf. My next headphone will be a £20 Sony I think.

Now I know for sure my SR80s have a rattle in the right driver all the way between 25 and 110 Hz at moderate to high volumes. Even more of a reason to be looking for new cans.

Have a look in the driver for a stray hair. That happens a lot with Grado.

Indeed. Happened to my Grados. A blast of air managed to dislodge it for a while…
That binaural test almost made me jump out of my chair the first time I played it

Brilliant! Got it. Thanks, Ian!

Great. It's a Grado 'common' problem.

I used to get that issue with my Sennheiser HD480s... seemed very prone to hair ingress...
I downloaded most of the Audiocheck files. The bass sweep track will not play through my Laptop / Squeezebox... will look into it later. The perceptual sweep is very interesting. Played through my new Oppo PM-3s it sounds as even as one could hope for, apart from a little bass lift, which is nice. The full 20-20k sweep shows the matching between L & R drivers is good; the best I have heard on any of my h'pones.
The upper hearing limit test is an odd one. As the tone sweeps down I get absolutely nothing until c.11kHz, then it kicks in suddenly. Is that usual? Until that test I believed my upper limit to be =<14kHz. I'l use Audacity or similar to make some tests of my own and see if that agrees with Audiocheck.
The binaural sample is short but stunning. As I mentioned alsewhere, my new PM-3s are brillaint at binaural when, as a closed-back design, they shouldn't be as good as open-backs.

And what about the spoken dynamic range test? Really surprising how soon you can't hear the numbers.

I have put together a track with a sequence of 5 seconds each of 16kHz, 15Khz, 14kHz, 13kHz, 12kHz, 11kHz and 10kHz. With my 'phones, 16kHz I can't hear, I have some sensitivity at 15kHz, better at 14kHz and then it ramps up steadily. There's no sudden jump in my sensitivity at 11kHz.
Edit...
the Audiocheck track is fine, and the results corelate to my own test track. The voice over is SO loud I wasn't playing it a a level where I could hear the 14kHz tone coming through. My fault entirely.

Reading that Derek made me smile... You have worries about your hearing?
I'm hearing on the pitch test reliably to 14khz. Mind you, I wasn't using a great headphone. It would be interesting to redo the tests on a good and bad headphone, just to try and work out the exact differences.

It appears I can still hear to about 16kHz. Not too bad for a 52 year old factory worker who frequently runs a chainsaw to heat the house. Hearing protection works! The sweep test is a good tool, as I can clearly hear the bass roll-off, as well as the biggest resonant peak in the treble right around 10kHz. Really shows the inherent shortcomings of my phone, as well as the limits of my own hearing.

Is that the Grado you tried on Joe?
Big bass roll off on them and also a big treble peak, which you are actually hearing on those tests?
You might be hearing further up because the Grados do play loud up there somewhere!!

Great. It's a Grado 'common' problem. The Koss PortaPro / KSC75 / KSC35 also have this 'hair' problem. I did the 'quarter-mod' and is hasn't happend since then.
