90 hours — that's how long a single charge lasts on Beyerdynamic's new Aventho Y with active noise cancellation turned off. Switch on ANC, and that number drops to 60 hours. It might sound like a trade-off, but by over-ear headphone standards, that's still a solid figure. Fast charging is another handy detail: just five minutes plugged in gets you six hours of listening time.
What really sets these headphones apart is that the battery itself can be swapped out by users. The ear pads are also replaceable, and the sliding rail and hinge structure are designed so that wear-prone parts can be replaced individually instead of forcing you to buy a whole new pair when something wears out. Beyerdynamic's official stance is that they want users to "replace high-wear components, not the entire headset." This design philosophy mirrors the brand's flagship MMX 230, which also features a user-replaceable battery.
