Closed-back vs. open-back headphones

Sometimes referred to as simply “closed” and “open,” this distinction addresses the design of the part of the headphone that covers the area behind the driver in a straight line away from the side of your head. Closed-back headphones like the ATH-M50xBT2 prevent sound from escaping and leaking into your microphone. The downside of this design is that it traps pressure inside the headphone, which creates false low frequencies. Open-back headphones, on the other hand, don’t suffer from this issue. They deliver outstanding accuracy and clarity that are suitable for critical listening.

Circumaural vs. supra-aural headphones

In layman’s terms, these words simply mean “over ear” (circumaural) and “on ear” (supra-aural). In the case of headphones, this refers to the design of the earcup, which is the cushion that sits between the headphone’s speakers (drivers) and your ear. Supra-aural headphones are rarely used for professional applications; although, they’re great for casual listening — especially if you need to be aware of what’s going on around you. On the other hand, over-ear headphones such as the ATH-M50xBT2 offer excellent attenuation of external noise.
