Pros: The sound is pretty balanced, everything is detailed.The sound quality is almost like the things you hear when not wearing headphones.
Cons: feels weak because of the little sideways swivel feature they added to it.
sound quality=great with more detail than the m50 and q40 i owned by a noticeable margin.(they still sound pretty good though considering the EQ settings they have by default.
the srh840 pads give it a whole different sound.ill stick to the 440 pads because the pads seem to give all headphones their sound, some better some worse.
the srh440 is like a dt770 if you equalize the bass up 5db or so.
build=everything feels strong except the swivel function that is somewhat necessary.they should have extended the amount yo could turn the headphone horizontally, probably would have made it just a dollar more.
no batteries are needed, blocks out sounds at 25% volume, not recommended if you are needed by someone at the time of usage, unless you wear these at night.I advise using studio/computer speakers during hours when you are needed so you can hear whoever trying to get your attention at the moment, despite still being able to hear music at the same time.
comes with 1/4 adapter for better systems, case that's soft and protects from minor conditions such as walking, running etc anything not involving vehicles or aircraft unless you are stationary and not operating anything.
good for sound design.
good for gaming and meda.
good for blocking out noise at reasonably low volumes as to prevent damage.
