For anybody saying that these sound thin or inferior to any other stock buds that any manufacturer is providing, I have to guess that you didn't yet find the "sound quality and effects" subsection at the bottom of the page under "sounds and vibrations," which I think is a stupid place to put such a premium set of features. At the top is the Dolby Atmos option, which I haven't tested yet because that is for movies, etc. You may have even heard the process in some better theaters who may have 1 screen dedicated for it. I saw the last two of the recent Planet of the Apes films in Dolby Atmos. Incredibly clean.
But as far as the buds, I just tested these in the "real world" setting of a coffee house with 22 people in it for their morning coffee and chat. As far as blocking out noise, it isn't 100%, but I don't know of any that are. But I will say that I started when the place was basically empty and it wasn't until I took them off an hour later that I was shocked by how loud the place had gotten. That increase in ambient volume in the Cafe was basically unnoticeable with the AKGs in.
As far as the music, this was a test for myself, but I sat and first played my favorite speaker test track; Oliver Nelson's Stolen Moments. I first went to the stock genre equalizer presets and the Jazz setting was noticeably more appropriate than the others. Historically, these types of presets have always felt more random or approximated by the software. But not on this. So I left the manual equalizer controls untouched, even though there were a couple of tweaks that I was feeling compelled to change. But the treatments below that are where the real satisfaction comes. For the lushness of this track, I had room to move by flipping on the UHQ upscaler without it getting tinny. And then I added Tube Amp Pro for warmth. I am sure that on a lesser device, these options would have simply canceled each other out and sounded relatively the same as having them both off. But not here. They are performing very distinct functions.
The next track was the RVG series' Lee Morgan's - The Sidewinder (you guessed it, I listen to a lot of jazz). And on this track, with Lee's trumpet being (understandably) so far up in the mix, the only Chang that I made was taking off the UHQ.
But then I saw this thread and tested a bit more. Moved to Mercury Rev's Dark is Rising, another of my favorite speaker test songs. I moved Jazz to Rock, took off Tube Amp and added UHQ again. It was probably fine, but I couldn't control myself any longer and did very modest tweaks, bringing up the mid and bringing down the low ever so slightly. Then Mudhoney - Baby, Can You Dig The Light (Tube Amp back on). Then Handsome Family - The Woman Downstairs (not that I think that they are pop, but the Pop preset was the only change that I made to make this song transplendent). Then went to the remaster of ZZ Tops Fandango to bounce around between live and studio tracks, just to test out the "concert hall" feature. The reverb in the original mastering of this album, already adds a distinct level of depth on the live and studio tracks, which was part of the ZZ Top sound through that era of their career. I wanted to see if the added effect pushed it over the edge or not. So I moved Pop back to Rock and added "concert hall" to this already live track; Thunderbird. With the caffeine of my xlarge coffee refill coursing through me, it was hard to contain myself as this was only the second time in my life that I thought that this feature ever sounded right. The first being Bob Marley's Uprising on vinyl in the early 90s through a pair of Klipschorns. I still get chills thinking abould the first song played through these already seasoned speakers; Coming In From the Cold. (note: my current regular buds are also from Klipsch, so the AKGs have had a lot to stand up to)
I then moved on to my two favorite songs on this album; Nasty Dogs & Funky Kings and Blue Jeans Blues. NDAFK sounded great with concert hall and all other settings the same, but I also played the first minute or so minus concert hall and that would be my preference. And lastly, for Blue Jean Blues, I put concert hall back on and the opening guitar sounded cool, almost haunting. But as soon as the vocals kicked in, it was too animated sounding to continue with concert hall, but the song was pristine without it.
Of course, I won't be doing this kind of switching around once I find a more universal, personal sweet spot in the settings. In fact, there is even a function at the very bottom that seems to figure that out for you, as well. Maybe I will try it at some point. But if anybody is feeling let down by these ear buds, make sure that you you have given them a fair chance with how they were intended to be used with the S9.
Peace,
