Shure True Wireless Aonic 215 Announced
If you like the design or not, Shure is a brand that's synonymous with audio quality. Their first adventure into the true wireless headphone space is the Aonic 215. Shure states that you will get up to eight hours of battery life out of these not so small guys.
Due to the shape they would be pretty hard to shake off, exercise might be a good place for them. You'll probably be looking at around AUD $400 if you want a pair though.
