That is a great way of explaining the differences, very aligned with how I hear them. For us at HEDD there is no doubt, that HEDDphone TWO is a better engineering tool, which was the primary goal - and the bass response is a perfect example: close to similar frequency response compared to HP1...

So sorry for the hiccup with that replacement! I am so glad you like them. Keen to hear which amp you will go for!

Agreed, the shelving EQs on the Zaehl are incredibly smooth and musical. We are lucky to have an early Zaehl HM1 in our company.

Thank you Marcus for your thoughts and the time / patience you invested into the review!! Hope to see you soon. Best, Freddy

Thanks for the shout! The HEDDphone TWO / MASS-kobo combination was mind-blowing, quite addictive.

Yes, AMT is a permanent development process at HEDD and we are taking customer feedback more serious than ever. Mastering legend Bob Katz once told me he finds HEDDphone TWO very flat in the good sense, that all the frequencies are there and it's a tabula rasa for EQ. HEDDphone TWO will happily...

Fair question! The current HEDDphone ONE / TWO driver design makes it indeed a bit trickier (compared to planar / dynamic headphones) to freely tune in the sub-bass region; we would need more space in the driver and a different geometrical line-up of the AMT/diaphragm folds. All doable, but not...

Thanks, that’s wonderful to hear!

Thanks for the mention, Sir! If there are any questions reg HP ONE or TWO, please let me know. Cheers, Freddy // HEDD

It was really fun to finally open up🙏🏻

Let me know what you find! Where are you based, if I may ask?

I really respect Joshua and think he is excellent at what he is doing, but of course I was super surprised, and so was everyone working at HEDD. I think we owe it to the situation to find out, if his unit had some sort of a driver-related (or tuning) issue. That's doing our homework. We will...

Das musst Du wirklich selbst herausfinden! Ich denke: Ja :)

Phew, let me grab a coffee first :relaxed:

Hey yes I can confirm lower distortion especially around certain areas where HP1 was a bit on the sensible side (like 900Hz for example). But also a much better control of inner body / cup resonances. Well noted on the music (I had doubts myself tbh :zipper_mouth:)

Yes thats a possibility for sure. Key learning for me is: That there is a place for us in headphone world. Building a headphone portofolio over the coming years is one of our priorities.

Appreciating your comment, capturing the sonic complexity of an orchestra is the hardest thing, also when designing speakers. Both me and my father (HEDD Co-founder Klaus Heinz) come from the world of classical / post classical music and active musicianship and tuning our products always...

The difference is huge. To this day HEDDphone TWO has fit everyone who came along to listen, event giant heads as recently encountered in both London and LA (and several places in between). :raised_hands:

Haha, yea that's a good one. A colleague of mine called V1 the "Cybertruck of headphones" the other day:)

Sadly not, it is a completely new mechanical design. Literally started from scratch. Sorry!

Thank you!

Both really good options, we use RME in our development process / RD lab everyday, very pleased with the clarity and feature set of these!

UK dealers will have them very soon, Scan Computers / SX Pro / KMR offer pre-orders already.

We once had a customer suggesting to build the OG HEDDphone into a helmet ;)

Do .... not .... :alien:
