My current portable headphone I use is an Audio Technica ATHESW9A which I'm very happy with. Unfortunately, the left channel stopped working and I just sent it in for repairs. I'm sure it will make its way back to me working fine, but I figured this is a good time to look at what else is out there. I'm looking for something similar in size as they fit my ears well (I have small ears) and they are easy to travel with in a backpack. I'll mostly be using them during my morning commute and at work for hours at a time, so comfort and noise isolation is a must. Since I'll be out with them, good looking headphones would be great. Music that I normally listen to are rock, electronic, and metal. These will also be unamped. tldr: Portable over the ear headphones ~$300 or less Comfort and noise isolation a must Indoor and outdoor use Unamped. Driven from phone and PC. Music: rock, electronic, metal Bands: Tool, Nine inch nails, Daft punk, Muse, Radio head, Metric Thanks!
