Context of Immerse
If you want to completely immerse yourself in your favorite tunes, a nice pair of in-ear headphones is the best way to do it. They form a tight seal that blocks out auditory distractions and delivers every sonic detail directly to your eager eardrums. Campfire Audio, out of Portland, Oregon, makes this extraordinary pair of in-ears with planar magnetic drivers inside. Unlike traditional piston-style drivers, planar drivers have a single piece of sensitive metal that’s vibrated by magnets to create ultra-smooth sound across the entire frequency spectrum.
