Yes there is a drastic difference between open and closed, really just think closed back to open back headphones. Much more airy and natural sounding.
All the way open will obviously let in ALOT of ambient noises, it's not really noticeable if you're listening to music (very much depends on the volume however). I leave mine in all day at work and just hit the pause button to carry on conversations. You'll still have the boomy-in-head sound like with air plugs and such, but the noises coming in are very natural sounding and normal volume (or really close to it at least).
If I'm listening to music at a medium volume and somebody approaches from behind me, I still tend to hear them if they're talking, but wouldn't hear their foot steps on concrete. Sorta a weird thing to describe honestly, hope it paints a picture somewhat to what you were hoping to have answered.
Out of interest, do they let more sound out as well? I'm always aware of being one of those ******* on the train who shares my music with everyone... XD
Also, to everyone - bit of a random one. I'm using my U12s a lot with a Nexus 6P. This is clearly by no means a good source as I believe its just Qualcomm's on board DAC. Ive noticed at really low volumes I can hear sort of hissing amongst the audio. It's only there when something is playing, not just in general. It's almost as if all audio suddenly has a layer of bad compression on it - not obvious, but there. I'm wondering if this is to do with impedance - these iems are still pretty loud with this source at lowest possible volume when in silence. Is there a cable that would help with this at all? I was thinking of 'Linum Music' or 'Linum Vocal': http://www.linum.dk/product-overview/
I don't believe the cable makes a significant/ noticeable difference to sound signature, and this has been shown in blind testing, but impedance is a pretty direct thing. Would one of those help do you think? Or any other suggestions for this kind of thing?
EDIT I also tried on the Note 3 which apparently has very clean output (GSM arena) - less of an issue, but still slightly there. I'm a little confused about what I'm hearing?
It's actually less of a "hiss" and more like sort of static... but VERY quiet, and only perceptible at the lowest voumes.
