Are wireless headphones harmful?

Andrew Huberman has expressed concerns about the potential health effects of using wireless headphones, particularly Bluetooth types. He personally experienced health issues such as lymph swellings behind the ears, which were associated with using these devices. These swellings would drain lymph if they grew large enough, which was both troubling and uncomfortable for him. After stopping the use of Bluetooth headphones, these symptoms ceased, and they recurred when he resumed using them. Huberman also noted significant heat effects from these devices. Although some experts he interviewed, including a neurosurgeon, did not express concern about the electromagnetic fields (EMFs) emitted by wireless headphones, others did. Due to these personal experiences and the mixed expert opinions, Huberman personally opts for wired headphones to avoid any potential risks 1.
