Ranked in these QuestionsQuestion Ranking
Pro Good portability
The traveling case is small and provides room for spare batteries and other components. This makes it pretty portable, for those that can't or don't want to leave their headphones at work.
Pro Can be worn for hours straight thanks to these headphones' ample comfort features
The QuietComfort 25 headphones are really comfortable to wear for long periods. These have very soft ear pads which go over the ear. The pads have nice cushioning, and are covered with supple and high quality synthetic leather material.
The headband also features some padding, with the inner lining featuring Alcantara which feels really nice on the skin.
Pro These headphones are quite enjoyable to listen to, thanks to the fairly balanced and lively sound that they produce
The sound signature that these headphones have can be described as quite balanced, with a little emphasis on the various frequencies. The bass is full and punchy. While the sub-bass is not pronounced, there is good and fast bass extension, and this is what gives the music punch and a sense of tightness. The mids are full and slightly forward so vocals and guitars can be clearly heard. The highs are clear and do not distort at high volumes. There is a peak on the upper treble which helps to add more detail and clarity to the music, but some may also find the high frequencies to be quite harsh at times. Overall, this is a really fun headphone to listen to, especially if you just want to enjoy listening to the music.
Pro These headphones are not tiring to wear as they are light
The QuietComfort 25 headphones will not tire your head or neck out, even if you wear them for quite some time. These headphones are pretty light at around 196 grams so they will not put a lot of weight on your head.

Pro You can really focus on the music with these headphones due to the very effective Active Noise Cancelling Feature

While some people active noise canceling, Bose QC 25 in particular has a lot of complaints about "ear drum pressure".
