"Brilliant."5.0 starson by Mediaslave
Pros: Read below! Summed it up nicely I think.
Cons: Pricey. Also...pricey. :D
Summary: Its amazing the difference a good set of headphones will make. I've always bought cheaper ones, around the $40 mark. This was my first set of expensive phones, and I'll never go back.
Sound quality is excellent. I was concerned that they'd be all low end, and miss the highs, but thats not the case. I use a creative Zen, and with its EQ I have them matched perfectly so that I get a wide range of sound.
The buds are mint. They are light enough that they aren't cumbersome, but solid enough that they don't feel like they'er going to fly out. The multiple rubber bits help you customize them to your ears nicely too.
The cord is a softer rubber, and doesn't transfer sound when it rubs on a coat zipper. Its also far less intrusive than other headphones that I've tried.
Monster's support is excellent as well. I had an issue with my frist set (one of them cut out) and Monster took care of me quickly, and politely. Excellent service.
I can't say that I'm going to buy a ton of Monster stuff as I find the cables to be silly overpriced marketing fluff, but the headphones...I'm sold. Great investment.
