Pros: Sound quality, construction, spare parts available
Cons: do not fold
Old timer which is still the best.
I love its dynamic sound but can brings fatigue after some hours.
Every things is there :bass, mids & highs with good details.
Every parts can be changed to make sure it will last long,
The only complaints I have : it doesn't fold
I think it is still the best on-the-go headphones
