A complaint about the XM3s were that they didn’t support multiple connections to easier switch between different devices. That appears to be fixed, with support for two connections at once, useful if you want to be connected to your phone and computer throughout the day, for example.

Also added in the listing is “Precise Voice Pickup Technology”, which is a fancy way of saying that the call audio should be better. The headphones will have five built in mics to better capture your nattering. DSEE Extreme (Digital Sound Enhancement Engine) smarts will also upscale compressed digital audio to a better quality.

The ‘phones are listed at $348 on the listing, so they are pricey – but if they .improve further still on the amazing XM3s then they’re going to be the best product in the category.
