What do you consider to be a decent battery life figure for a pair of wireless headphones? 20 hours? 40 hours? 50?
Whatever your expectations, you'd struggle not to be impressed by the prospect of a massive 90 hours of playtime from your wireless cans. That's just what's being promised with the ATH-S300B, though, Audio-Technica's new ANC wireless over-ears that deliver nearly four days of playback from a single charge with noise cancelling switched off (and 60 with ANC on). For context, the Award-winning Sony WH-1000XM5 will give you 30 hours without ANC, while the more affordable WH-C720N cans will give you around 35 hours under the same conditions.
