Grado Sr125x

Consumer Reports rates the SR125x as delivering excellent sound, with open-back design benefits like strong awareness of outside sounds and good volume from home or portable sources. It also notes that bass has good impact but can be somewhat prominent and boomy, and that the headphones create moderate pressure on the ears.

This user review says the SR125x delivers noticeably better detail and a slightly more balanced sound than the SR80x, with a bit more bass. It also says the headphone can become fatiguing and is uncomfortable for long sessions because of the stock earpads and overall fit.
