Headwize used to be the place I'd hang out to discuss and enjoy DIY headphones and headphone amplifiers. The site is now memorialized below but has a wealth of information. https://headwizememorial.wordpress.com/

It's been a few years since I went there, and now I'm sad to see it's gone.

Those reviews helped me get some excellent bang for the buck headphones years ago.

Hang on a moment. Headphones can be the best in the world but uncomfortable on my wonky head or incompatible with my glasses and they're worthless to me personally, so I'll give him a pass on that. I have some not-audiophile-but-better-than-meh headphones I rate very highly because they're nicely made and super comfortable; they sound good but that would count for zero if they didn't feel nice. Room acoustics, though…

If you're in a noisy room then open-back unisolating headphones are not "more accurate" than closed ones, because you can't hear the audio.

You don't get bass or spatial imaging if they don't fit on your head. Glasses are enough to break the seal.

Reviews of Beyerdynamic headphones shouldn't tell you they're good without also telling you they have poor audio tuning with a treble peak that makes things sound "sibilant". You might be the kind of person who puts an EQ in your headphone path, but most people should go for something more neutral instead.

I don't know what in my comment made you assume I use an EQ. As a first-time Hi-Fi headphone buyer, the reviews on Amazon and Youtube didn't surface the nuances of the different headphone models using quantitative information as DIY-Audio-Heaven does.

That was a generic "you".

The room you're in has no bearing on headphones, except perhaps for the background noise.

Having a wonky head, however, may affect the seal of the pads against your head, or the headphones may clamp too much or not enough, or the cups might be oddly angled, all of which may affect the sound somewhat.

Same with ear shape versus driver placement. If you have shallow or deep pinnae, that may make a difference depending on the relative location of the driver.

Almost all spatial audio is built around a head related transfer function, which attempts to model all sorts of things, like how much sound reflects off your shoulders and other such things, although those questions are usually considerations more for DSP than they are for the tuning of the headphones themselves -- in cases like the Airpods Pro & Max, though, those two things may be one and the same.

What I'm after and can't seem to find are good quality¹ glasses frames that have (bone-conduction) headphones built in to the stems. I want to replace my existing prescription glasses with this. ¹ E.g. Spring hinges, nose pads.

These have nose pads: Cooyee CY02 https://amzn.com/dp/B0BS5KRC5X $100

USD 40,- sounds like a steal. azn offers them for 180 eurodollar: https://www.amazon.de/dp/B00ENMK1DW/

Even 30 USD: https://www.thomannmusic.com/superlux_hd_662_bk_evo.htm It's amazing how prices of an item fluctuate across markets. (One can remember iPhones and macbooks priced the same number of USD and EUR during pre-COVID times.)

That's a different pair of headphones, isn't it?

These cost 33 EUR in Germany (VAT included). So not much of a difference compared to the USA. https://www.thomann.de/de/superlux_hd_662_bk_evo.htm
