Pros 1. The sound out of the box is great and will only get better with age.
2. Though 12.3 oz seem heavy, they really don't feel it in fact they remained comfortable for long periods.
3. They do a great job of keeping the music inside the head phones.
Cons 1. They do sit tight on the ears and what they used for the headphone liner tends to make you ears a bit warm.
2. The cord is to long to make them mobile and they did not come with a case.
Summary Despite the faults these are a great pair of headphone that you can get for a steal. The last time I bought a pair of headphones this good was 6 years ago and I paid close to $200. Which I was still using until these came. So fast forward 6 years and here we are I just bought a pair of $56 headphone off Amazon and they sound a hundred times better than the pair I bought for $200.
