Pros: Very well balanced sound. Crisp Highs and warm midrange. Lows are not punchy but rather smooth and powerful. Outstanding sound isolation. Comfortably tight in ear canal.

Cons: *Stick out from your ears a bit so you can't sleep with them in unless you don't move in your sleep. *At first use, the swappable foam surrounds take some toying around with to find your ideal size. After that it's all good. *The urge to upgrade you recordings to a lossless format :)

Overall Review: I was a bit surprised that this product had not had a review on it, so I wanted to share my experience with you. I picked a pair of these up just a year ago and they are amazing. Sound Isolation- This was important to me due to flying alot. I wanted a pair of headphones to drown out the noise of a jet engine, sitting in coach, with a baby crying a row over. This pair stood up to all those tests at once, and I only had the volume up halfway. I could hear nothing but the sweet synthetic sounds of Owl City, and the powerful belting of Carrie Underwood as I neared my destination. Sound Quality- As I started listening to my music, I could pick out things I've not heard before in the recordings. Low notes that filled the empty space, artists hitting flat notes, and backgrounds that escape the ear on other speakers. Now it's time to only download lossless formats when possible! In short the SE310's bring to life what your other headphones can not, and your recordings long for you to
