I listen to music all day at work - CD player via optical, Fiio X3 coax FLAC. Currently I love listening with Sennheiser HD650 with a Schiit Vahalla with Bifrost Uber Analog. I do not listen to the music at very high volumes - more interested in clarity and soundstage of the music.
Early in the morning the Sennheiser HD650's are great. However, later in the day the open ear causes some disturbances since I work in an open office environment.
Very interested in some recommendations for over the ear closed back headphones to use with Schiit Vahalla/Bifrost....
