Hello folks! I've been an IEManiac for the past 6 months or so, but I need the low isolation provided by earbuds for the office. I received my KB Ear Knights a few days ago and I am pleasantly surprised with the sound, build quality and the price. However, I am afraid my ears are too big and while they do not fall out of my ears, they never have a tight fit. I have the black foam donuts that came with them on the earbuds, but I cannot, for the life of me see how to double them up. The bass is much better when they are physically pressed against the ear canal. Please advise if there is any workarounds I should look into, or another, thicker-shelled earbud I should consider.
You could try putting silicone rings around the earbud and add foams over it.

If that does not work for you, the only earbud in my collection which I find to be a bit larger than most is the NiceHCK ME80.
