There are also these Earasers that I'm considering trying out.
Although, I'm a bit concerned because everything people are saying about these, I can say the same about my Hearos High Fidelity plugs. I mean, $40 for a pair of Earasers and $12.99 for the Hearos High Fidelity plugs. So, I don't know. I am considering giving Guitar Center a call to see if I would be able to return the Earasers if I don't like them (such as, if I think that they're not so much better that they're worth the extra cost).
