They have their issues, but quality ear plugs can be a decent substitute for a quiet working (or sleeping) environment. The key is to find a variety that is comfortable and works well for your ears. I started by ordering a variety pack of 35 different types: http://www.earplugstore.com/unfoamtrialp1.html
From these I ordered a large box of the two that I liked best:
The (green) MaxLite are the most comfortable I found and quite effective, and the (yellow) SoftFX are quite comfortable and extremely good at blocking noise. I mostly use the MaxLite for sleeping, and the SoftFX when I want something in the daytime. Since each pair can be reused at least a half-dozen times before they become too soft and start losing their effectiveness, I should be set for another 5 years or so.
If you've tried ear plugs before and felt that they weren't effective enough, it's possible that you weren't wearing them correctly. They need to be inserted quite deeply into the ear canal, and need to be rolled tightly before insertion to make this possible. And then there is the slightly-embarrassing-but-essential "pinna pull": http://www.e-a-r.com/pdf/hearingcons/tipstools.pdf
