Apple AirPods pair and connect but no sound
If you did a hard reset and they don't work with either your iPhone or your laptop (multiple devices) it's safe to say that they died.
They're under a month old so I would return them for refund/replacement immediately.  Products fail - it happens.  You're just lucky enough that it happened during the &quot;return to retailer&quot; period (usually 30 days) and not when the warranty runs out 48 weeks from now.
