Yes, headphones won't be a problem like i see, it looks like you just have to practice, some people here got doses to work after days, some people after months of trying so definitely don't give up. Just practice, try doses more and more, use condition, and believe it works. Some user described this really well: "It's like love, you won't have it if you don't want it". So, just don't give up!
And what A-BOMB does? Uh, it's really hard to describe that feeling (well, it's really hard to describe feelings of every dose but some people can do it anyway
). You can read my review on A-Bomb here
or read Pony's review here
(definitely better choice
It doesn't matter what kind of doses you are friendlier with, you should try A-Bomb in any way.
So that's all from me, have a nice day and enjoy dosing!
