I'm not overly sensitive to EMFs, however with apple airpods I noticed I would have earaches after prolonged use (30 min +). Got rid of those with the quickness. No such issues have ever occurred to me with wired headphones. Ive even used a pair of Bluetooth Bose ear buds, as well as a set of V-MODA Bluetooth headphones for extended periods, but havent felt any earaches with them. Even still, I always go wired if possible... Healthier in the long-run, and better sound quality
