"The HFI-15G’s are by far, the most comfortable phones that have ever graced my head." "With the Ultrasone’s, I didn’t have to give up quality for comfort. Literally, after many, many, many hours of gaming, I don’t feel the need to ‘rest’ my ears or head. The over-the-head band has just the right tension as to hold in place, but not feel tight after time. The foam padding around the drivers is thick and of medium density, and comfortable as all get-out. The lightweight design of the headphones is no doubt a large part of the comfort factor. Red-ear be gone!" 
Overall, they conclude that these are a great set of headphones for the price and if you are looking for comfort, you can't go wrong with these.
