To your ears, is mid-blass bleed related to time (transient speed) or frequency (separation of mids and bass frequencies)? Some mean the latter, and in that case, the P1 Max II is definitely a mid-bass bleeding set.

Hi @MidnightSun , I would say it is probably both factors combined.

I find planar drivers (like in the P1 Max II) are usually more speedy than DD bass for example, and we also have to factor in the rest of the frequency response (not just the bass in isolation, but how it relates to the mids and treble). One also has to factor in hearing health, volume played at (Fletcher Munson curve), ear anatomy with eartips etc.

Nothing beats putting the IEM in the ears to have a listen, rather than just looking at a graph.

Thanks for the answer!

Clearly a preference to warmer darker signatures. Maybe his gear?

But yeah the ZX507 and 707 aren't very impressive technically (dynamics, clarity, detail, soundstage, etc) for the price point.

Hi, from our test data, the noise floor of the M23 is lower than M11Plus. May I ask under what conditions did you test it?

All due respect, but this DAP is a super star. Faster than any DAP I've used. VERY nice tonality.... just a click or two on the warm side off neutral. Who cares if the chip is slow if it runs like my iphone 15 pro max??

I have access to sp3000, sp3000t, WM1ZM2, hell even the DX260. The m23 is WELLLLL worth the price and then some. In my opinion of course.

Not that it matters, but for anyone curious on the switch config. Thank you for the nice review

Kwsizer maybe you like this headphone soo much that you doesn't want anyone to say something negative about your choice even if it's true. This headphone have Pro in it's name and it's far from it. If someone knows how to read frequently chart which you probably didn't, they'll know how far it is from being neutral. I've better reference headphones in my collection and it's far from them.

It's rather silly to judge and then slam a hp only because they have the "pro" word in their name. Deal with it.

Hey, I also own these headphones and my thoughts are similar. At first I was somewhat confused, like bass was there but very quiet and not.. put together? Tone is bright, maybe too much for me, although sound stage is pretty open just like you say and detailing is alright. Well, turned out it's difficult to enjoy music on them without EQing. Here's what I've got after some experimenting (personal taste influenced): link

You mention pre-2023 version differs in sound, what I have is manufactured in Romania and production year 2021.

I can see that something about this set was off for you

Nice review, think Bonneville is either you like it or dislike it.
I can't live without Bonneville, and have sold many other sets due to it.

But can see it not being for everyone, very subjective what we like or not.

Anyways keep up the great work you do @Jaytiss
