Can I fix these airpods?

My dog just bit my left airpod (crying). It’s now producing low quality sound and with low volume below 180 Hz, above this range it works perfect. I think it could be something to do with the airflow for bass. Do you think could fix or improve this somehow? Besides the hardware fix I was thinking if there is any app that prevents only the left airpod from playing frequencies lower than 180Hz, this would greatly help me. The airpods are not covered by warranty anymore.
