Audio-Technica ATH-M40x vs Sennheiser HD 280 Pro 2016

The Audio-Technica ATH-M40x and the Sennheiser HD 280 Pro 2016 are both closed-back headphones with reasonably balanced sound profiles. The Audio-Technica are more comfortable, which makes them better suited for long listening sessions. Still, their exaggerated bass and treble ranges can sound quite boomy and even piercing at times. However, they deliver audio more consistently, with less deviation in the bass and treble ranges between listening sessions. The Sennheiser have a much more balanced bass and smoother overall sound but aren't as comfortable.
