I've had mine for about 45 years now and I love them yes sometimes I will hear Korean talking out of one of the earbuds but once they pair with my phone everything goes back to English I don't understand why people are saying that they are having a pairing issue I have not had this problem with mine
Multiple times I have been in scenarios where I'm in my garage at night doing stuff and I'm not necessarily handily with the flashlight right next to me and then all of a sudden the auto lights turn off and I'm trying to hold a transmission up😂
