Negative Positive
Title: Awful
Review: I own the Bose QC2. The QC2 sounds great, but they are big and carry-on space is always at a premium. I wanted to try the smaller Sennheiser 300's. They are smaller, but they do not do a good job of cancelling out the noise. The right side was particularly bad. It seemed that the noise of the engines "leaked" through. I recommend avoiding these.
Is the review positive or negative?
