What glue to use to glue back together ear pod

i had to open up one of my ear buds since it stopped reading inside the case. i was able to fix the issue after meddling a bit inside but the factory glue doesnt stick anymore and ill need to glue it back together since tape is only a temporary solution. if possible i would like a glue that allows me to reopen it in the future if anything disconnects again. i read about using t7000 on an airpod question on this site but upon further research the glue is more of a permanent thing.
