I went through 2 pairs or Samsung Galaxy buds plus, and both of them became unusable due to some very weird issue when they get clogged up and became too quiet. After that I told myself I will not get any more bluetooth audio devices again. The only IEM I use are the Samsung earbuds for calls or use in school for years, and I cleaned the grill once and they work fine. I still think the $30 Type C Samsung earbuds are the best headphones or IEM for that price, they also have a really good mic.
