I am waiting to receive mine, it looks like a great solution for the Ember+low impedance headphones with most tubes 😀

Will this work fine with a HD 650?

There's no point attenuating the signal to the hd650. It's 300 ohms so doesn't need it.
It's designed to be used with low impedance headphones in order to give a wider travel for the volume pot and to eliminate amp noise that low impedance headphones are prone to.
If you used one with an hd650, you'd probably need the amp on full volume to get anything useful!

So high impedance bad, low impedance good? In that case I think I will order one for the HE-560 as that should be a better match (45 Ohms). Or perhaps if volume is still too high I could daisy chain two for even better attenuation. I think Frans said a single attenuator makes the volume 4 x quieter, so would two mean 8x quiter (or do you multiply; 4x4= 16x)? A simple yes or no answer please rather than beating around the bush like you did above

Just use 1!!! Frans will know the answer to the numbers!! A proper adapter keeps the output impedance low at the amp as well, so the sound (particularly the treble) is retained. Some of the cheap nasty ones raise the impedance so the sound of the headphone can change slightly, depending on the headphone used. Some are more susceptible than others so a proper adapter is best. It'll allow you to raise the vol pot to an area where it 'tracks' better and be less touchy between loud and soft on a powerful amp. Makes sense really. You might even be able to use the Vyrus with it!!! Do you pick up hiss with the he560 Mark? TBH as a general rule, I find most tube amps work better with higher impedances. For low impedance, I use as straight away so Polaris is better for me. I find tubes can be noisy with low impedance and just sound better with high. I thought I was being very polite........

You were being very polite Ian and in response to my very silly post! I was expecting you to tell me to p*** off!!
The HE-560 doesn't need attenuating. Although relatively low impedance like many planars it's also quite insensitive so needs some amping. Hiss is non-existent.
I have an ifi attenuator that I used with my old Ember when I wanted to try some IEMs and the Pandora. That would allow me to use the Vyrus with the Polaris I'm sure although I found the ifi one made things sound a bit 'sterile'. It's also not as well considered as the G1217 cable as it's very short and terminates in a 3.5mm jack (yet the ifi amps are all 1/4" I think!).

You're a bugger!!! I thought you might have a problem with the he560 but didn't want to suggest it!!!!! Sometimes, you're a bit subtle .........

Too subtle or possibly my sense of humour just sucks? That one can't be ruled out Perhaps we should agree upon a code word or phrase I can use to let you know when I'm on the wind up? Could be fun thinking of an appropriate one!

Got mine last week, but I could not test it until today. It is GREAT, especially with the Ember + D2000. The latter has quite low impedance and most tubes are just too noisy to use them with the Ember. With the attenuation cable and one of my noisiest tubes I barely get a very low background hiss. With normal tubes (not so noisy ones) I get a pitch dark background :-)
Totally recommended!

I am going to have to check these out if I can ever pay off my vet bills. I bought a pair over a year ago online. Can't remember where. Looked great on the outside, nice gold like case. Must have been junk on the inside. Attenuated the signal. And really killed the sound. Frequencies all out of balance, audible noise. Unlistenable. Returned them. The amp gets no use with my lower impedance phones. Needless to say.

I presume there is no degradation is sound quality? I typically listen at fairly low volumes. So I often have very little "play" in the volume of my amp. So this might work out well for home use.

Proper attunation leads don't alter the actual sound. The cheap nasty ones do though, by raising the output impedance.
What you're suggesting is a good use for one. It gives you very fine control of the volume at lower levels.

It will be added to the site today! Shoot me an email for quick ordering - I can send you an invoice anytime! Hi, I'm a newbie aspiring audiophile. Would you recommend this for a akg k7xx (red) into a raccoon sg-300 setup both from mass drop?

When:
You want more travel on your volume control (now is playing loud with the volume control slightly open already)
or:
When you want to lower the output resistance of the SG300 (from stated 10 Ohm ? to 3 Ohm) (I reckon output R is closer to 0.1 Ohm instead of 10 Ohm)
or:
When you hear background noise when no music is playing
or:
When the amplifier can play WAAAAY to loud
then it may be a good idea to use this attenuator.
