I had the buds3. I found the sound amazing, but only when I pushed down on them with my fingers deeper into the ears, which is just unfortunate as they do not stay in place for long. 3 weeks ago, I traded them in for buds3 pro paying £80. Have to say, I preferred the sound on the buds3, but only when I push down on them, which is something I don't want to constantly do. The buds3 pro has amazing bass and is loud but only on certain songs. Here's the horrible kicker. The crackling sounds when anc is switched on is absolutely dreadful. You get popping sounds, too. It does this on some of my favourite songs. This is an issue, apparently. I've seen reports on reddit. I've reset numerous times, but it's still the same *****, which is a shame as some songs sound amazing. I'm not sure whether to send it to Samsung for a repair/replacement or just sell them and buy the Sony xm5, which has amazing reviews. Many people complained about the buds3 not fitting and others complaining about this crackling and popping noises when you use anc on buds3 pro. Overall, I'm frustrated and disappointed with the odd levels of excitement. The crackling sounds go away when anc is switched off. The crackling sounds always do it on the same songs/music. It's not on every song, but it's there every day when I use them.
