    In his review Torq mentioned MySphere is second only to Raal without the need of specialised amplification. He does prefer 3.2 where I find 3.1 is the better headphone.

    This is directly from my message to Heinz a few weeks back:

    Yes, agreed that there is no such thing as fast bass, and that "fast bass" is mostly the result of transient response of frequencies higher than bass.

    In terms of correlating measurements to observed phenomena, impulse response by itself gives us some idea, but not enough. The initial slope only tells us about bandwidth, and in my opinion, we need more visualizations.

    Personally, I like to see 10 cycle burst responses (either directly recorded or IR convolved) at several frequencies, say at 50Hz, 120Hz, 500Hz, etc. I would then examine the behavior of the first few bursts before the sine waves stabilize. I would also consider how the burst stops, e.g. overshoot, time to settle, ripple. Applying a log on the amplitude (if pressure / voltage) also gives us additional visibility.

    There is some work on SBAF in this area of "fast" sound, but it is preliminary and immature.

    It's just slightly on the lean side in my book. For those who've heard the modded FD01 IEMs (or Drop FDX1), bass on the Mysphere 3.2 is roughly on the same perceptual level down to 100Hz. Below that, I use a low-shelf EQ of +2.5dB (Q=0.5) to compensate for the headphone's roll-off and match the IEM's perceptual bass response.

    That's with the earspeakers not touching my ears btw, of course one can boost the low end by wearing them closer.

    Of course, IEM's are a different story as long a it "pump" air into the ear channel... This effect even change everything

    Our loaner warchest is a bit low on funds as the result of @ChaChaRealSmooth organizing so many little loaners recently (shipping adds up like crazy). We have some stuff being sold that will top off our coffers. But given the price, SBAF won't be able to afford a loaner without any accommodations from retailers. We could ask around, maybe one of our sponsors.

    Even then, high priced loaners only go to trusted members, and I always feel bad about this.

    Maybe Heinz can set a unit aside for a few SBAF members to evaluate for a week each at a discounted rate? Doesn't have to be official although rules on Mysphere's side would apply.

    Again, a Test Set of Mysphere (including 3.1 and 3.2) to loan for one weeks comes for only 100 Euro... When ordered at Www.mysphere.at/shop.
    So what's the point?

    You can get such loaner for longer time, if needed... Just mention on the web shop your request and reason for...

    We will come to agreeable arrangements if we need to the loaner for longer or to be extended to a few people. Need to make sure it is fair for you.

    All understandable. Still, it would be interesting to see some comparisons, especially from respected ears. I think these kind of super open super transparent headphones have some appeal for those of us in thin walled apartments but with a hankering and possible budget for "end game (lol)" sound.

    I was not trying to imply that the MySpheres aren't fast, that they don't have clean bass, and/or that they don't have the proper transient and high frequency response to make bass sound fast. They very well may be excellent in this regard.

    I was only speaking from experience that when you deal with lean bass, it can fool the user into sounding fast and clean.

    I mean, the prototype Shortest Way amp sounded fast as hell in the bass. Why? Because the transformers had an appreciable bass roll off! I initially doubted that an amp could be that rolled in the bass, and assumed that the bass was just really fast. Well, I'm sure you know how the story goes. Very evident once the production models came with better extended transformers. (Not that those aren't clean and fast, but lean/rolled bass certainly sounds snappy!)

    Again, think of it as a measure of caution when we test and write up. Same way that veiled treble can fool the user into thinking bass is slow, when it's really just the high frequency element of a bass instrument being muted. Or how some might hear bass as loose and flabby when distortion, transients, low frequency bursts, etc. might be stellar, and it's just the frequency response itself that's elevated.

    It's also a common thing I hear for stats. They're either super fast or lean and rolled, depending on someone's point of view.

    Again, I'm not saying one thing or another about the MySpheres' bass, but more on making sure we're doing rigorous and commonly agreed testing, using same descriptors in same way, etc. If anything, it's more a broad commentary, brought on by this comment but not exclusive to the MySphere.

    If a SBAF (limited) loaner is going to happen, it might be interesting to wait just a little until these bass enhancement ear cushions can be shipped along as an extra pad option...

    Can you say a little bit more about this? Picture?

    [​IMG] The new cushion will slightly sit on the ear and increase the bass without reducing the frequencies above 2kHz...

    the picture below shows the difference in dB between the standard cushion and the upcoming new cushion:

    The graph freaked me out for a sec until I realized what I was looking at.

    Nice, dispersion control of some kind ?

    what do you mean with "dispersion control" ? Could you rephrase it for an Austrian please? ;-)

    Just wanted to point out that images aren't showing up for me, @Heinz Renner. Maybe you could just provide URLs, or use an external host like Imgur?
