Sennheiser HD 558 On-ear Headphone Review$179.00
Open-backed cans are called so because the back of their casings are open, allowing a huge range of driver movement for more accurate sound. Unfortunately, this also means that not only does sound leak out like crazy, but sound from the outside world comes in. Granted, even though your music will drown out some of the noise coming in, you'll probably want to limit the noise in the environment you're listening in.
Unsurprisingly, these cans leak a fair bit of sound, again due to the nature of open-backed headphones. If you're going to be listening in a highly-populated room, be sure to keep the volume at a minimum. These are not recommended for the office if you like to blast your music.
Maximum Usable Volume
Even though the Sennheiser HD 558 can blast out sound at a level of 117.17dB, we urge you to keep your volume at a minimum, as it is super-easy to fry your ears with headphones. If you'd like to know more about safe listening habits, check out our article on Noise-Induced Hearing Loss.
