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!

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

This review is totally wrong. I'm afraid you confused the headphones sound with your personal taste.

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.

why would it have ever transparency mode, it's not a true wireless bt earbud, it's just the adapter...

The FiiO has it. Maybe do some research before you spout off.

I do appreciate you taking the time to review our product, whether it is supportive or critical. We are aware of product quality issues that may develop, whether at the factory of manufacture, or during transport and storage before and during sale (e.g. extreme temperatures in transport and storage, a growing concern in this day and age, can damage products that were pristine out of the factory), and are always working to maximize reliability in every way we can.

@Joe Bloggs I am well aware of various technical scenarios, I'm an Electrical Engineer with credentialed work and projects. My review is ample enough to translate to do not purchase, I have several friends and met various users who report similar issues. I simply cannot recommend something I've had a bad experience with, would you? We live in a society where convenience is at the forefront. I refuse to buy another unit that may have inconvenience my day, by having to ship it back UPS, whether if I got a refund or not. I have better usage of time, and that is investing/researching into another product that better fits the bill.

Secondly, I have nothing against Hiby, I've heard nothing but good in relation to products offered. It seems to be a brand with good technical expertise, and various recognition with different items. Whether I am sounding critical, too harsh, blunt, upfront, may be deemed by the opinion of X user reading my review. Thanks for responding, and giving your just reasoning of the words I've listed. I just ask this product checks all the boxes before being pushed and marketed to the consumer market. I understand forces that aren't as controllable, but I wish this product success.

Nice review as usual.

Grrrrrrrrrrr, I literally just went to try an updated firrmware downgrade if that makes sense. After a completely full charge I open the case and notta, all power depleted, the left bud still have no operable use as far as I can tell. I’m about ready to throw these things out

IFI…PLEASE GET YOUR POOP STRAIGHT! I’m embarrassed for you! THIS OR advertise accordingly and stop misleading people. Who likes wires? if portable use to you means sitting in an arid part of the word on a cosier all day then I suppose you nailed it!

You may need to start a claim and have them send you a new set. I downloaded thr latest gaia from the website, disconnected the go pods, and after several tries, was able to connect both and roll back the firmware. I spent hours doing it though. Just file the claim on the broken set. If the other set isn't broken, then make sure you download the latest gaia to install, and then download the older firmware from there and your other set should be fine. It's either 1.49 or 1.42.

Thank you! I’ll do just that…..so frustrating. Enjoy your Sunday!
