0 FPS Spike Powerbeats 3

Some days I get 0 FPS spikes when using my Powerbeats 3, other days I'm fine at 180+ FPS. No other programs running, I don't have a bunch of little stuff in the background either. I'm using a new iMac with OSX Mojave, and running the LoL the mac client (beta forever). As soon as I disconnect the Powerbeats from bluetooth, the FPS goes back to normal, and then if I reconnect them it drops to 0 FPS spikes.
