Razer Nommo Chromas Keep Shutting Off Without Warning

Hey all! I'm having a problem with my brand new (I've had them for less than 2 weeks) Nommo Chroma speakers. After about 1 hour of gameplay on my PC, they'll randomly make a static sound that lasts about 1/2 second, and then shut off. No more sound, but the RGB accent lighting continues working. What might this be? Should I send these back while I still can and order a new pair of speakers? Thanks in advance for any helpful advice!
