For anybody that has had problems with ear buds in the past. A little warning for you. When I first got the buds Pro I was one that had irritation to my ears they would become very itchy if I used them for too long. So what I did was only use them for short periods. And over the months they got better, and the irritation to my ears stopped. I'm not one to have ear buds in my ears for too long, max few hours a day not even everyday. Recently I recieved my Buds 2 Pro. New buds couldn't wait to try them out. Listened for a few hours Thursday before going to bed, all seemed OK. In the night my ears started itching, woke up to them very sore weeping and crusty. There still the same this morning and this is the worse they have ever been. So if you have bought the buds 2 Pro, don't wear them too long to begin with if you have had problems in the past. Never had the issue with the buds + or buds 2. Obviously you can get discomfort and itchy ears after wearing in ear buds, which is normal. So I'm not entirely sure of the cause for my ears to get this bad. Whether it's down to new silicon and sweat build up. Only ever been an issue with the pro models. I will probably try and get different tips when my ears feel better. As I really like the buds 2 pro. New lighter weight design feels better and more comfortable, and sound very good.
