Alternatives to wireless headphones?

Andrew Huberman has expressed concerns about wireless headphones due to personal experiences with lymph swellings and heat effects near his ears. As a result, he opted to switch to wired headphones to avoid electromagnetic fields (EMFs) and potential health issues. Additionally, he mentioned another alternative: headphones with air tubes. These headphones do not have any electrical components near the head, instead using air tubes to transmit sound, which can be considered an even safer option for those concerned about EMFs and direct heat effects near the brain 1.
