For one of the best listening experiences, you should really think about diving into the world of high-quality hi-fi in-ear headphones. Professional musicians and audio engineers have been using these kinds of in-ear monitors (IEMs) for decades, because of their superior noise isolation and sound quality.
Audiophiles have also gotten into the mix now that IEM manufacturers have perfected the art of miniaturizing high-end drivers; consumers can now purchase custom IEMs with as many as 12 drivers at a significant price. The vast majority of universal or custom IEMs feature separate drivers for the treble, midrange and bass frequencies, too – and they’re still small enough to fit in your ears. For those with deeper pockets, planar magnetic and electrostatic driver technology are now a reality in the IEM category.
If you’re ready to dive into premium aural luxury, we’ve rounded up our favorite hi-fi in-ear headphones. Don’t want to spend several hundred dollars or even a grand? Now you don’t have to.
