Query: Much worse than expected based on other reviews

I carefully selected these after reading many of the reviews and seeing the average review score was excellent,with cost fairly inexpensive. I was quickly dissapointed as I found the headphones to be uncorfortable and the sound was not very impressive. I then read some of the negative reviews and they are right on the mark. The headphones are too tight (and I have a small head), the cups don't fit over the ears; they give me a headache within 5 minutes. Not to mention, the sound is no better than my 5 year old, inexpensive Sony earphones. On top of all of this, the pair I received seemed to be defective as the right speaker hisses a lot. Plus they are a little bulkier than I expected.
