I've talked to multiple people, seems the speakers are prone to break. Try running it for 20 hours on speaker, good chance it won't make it, considering most use headphones.  A few have stated they sent it in to get repaired, and it broke again after a few days.  Beware the speakers are weak on the Nokta legend
