Hi everyone, I am in need of a recommendation for closed-back headphones. I use my HD6XX daily and love them, but recently my housemates have been making a lot of noise due to work. Being open back, I can hear everything and I am looking for more isolation. I purchased the BD DT 770 Pro (250 ohms), and I absolutely hate the sound. I decided to give them a break in chance and now I can't return them. I do not like the Dt770 because they sound way too sharp and most modern music sounds so piercing; Even songs that I think sound great on my 6xx... Are there any recommendations for better closed-back headphones that sound more neutral or have an emphasis on mids? Headphones must be under $299.
