Pros: Light and compact design, works on active and passive mode,
Cons: On ear construction doesn't provide noise isolation, heavy battery compartment,
I'm biased against on-ear headphones. For a daily commute I use in ear monitors and for listening sessions nothing beats over-the-ears counterparts. At work isolation is not such a problem (neither a good idea for my line of work to be fair) but I don't see why people still need the type of headphones that doesn't bring the best of both world, or at least a consensus.
The active noise isolation IMO is more a gimmick because the on ear design doesn't provide a decent seal, so the noise canceling is useless.
To be continued.
