Razer Kraken 7.1 V2 rattling with low frequencies.

Only two months after my warranty expired, I began to notice a rattling sound in my Razer Kraken 7.1 V2 left earphone when a low-frequency sound like bass is playing or if I shake it slightly. Razer support won't help me because the warranty is no longer in play. Does anyone know how I can fix this? Thanks.
