Great all-round headphones can sound a little deep but music wise you can adjust with tone controls on device.
A nice trick we found was connecting 2 of these with a cable & splitter to TV, power on your headphone and you can adjust
the volume independently (great for fast action movies if you don't want to annoy your neighbors)
These are quite large headphones but are very comfortable, Connect to pones & tablets with no problems.
I have not tried the memory card slot yet so Cant comment on this feature, I always use my phone for music.
