Sennheiser CX300-S Earbuds

After doing a hefty amount of research on the topic of in-canal headphones, I have landed on the Sennheiser CX300-S model. I purchased them off of Amazon. com (Cost: $50) and will recieve them within the week. These headphones will replace the white Apple ones which, although a status-symbol, have very poor sound quality. These Sennheisers are form fitting to your ear canal, and thus, block out ambient noises. They are also extremely light and since they are bass-driven, they deliver crystal clear sound across genres. I am looking forward to personally evaluating these headphones when they get here. I'll be in for a day of music to my ears... literally(I hope).
