Great earbuds and an solid improvement from the Bud2 Pros especially wear- ability (they fall out of my ears way less) and a further improved ANC and sound quality.
I slightly prefer the surface/material and finish of the Bud2 Pros and wouldn't mind if the Gen 4 went back to a matte/rubber texture.
I picked these up as a bundle with a Galaxy Watch 7. I'm not one to wear Buds all day. In fact, I wear them seldom. However, the sound these buds develop is impressive. I use Power Amp as my music app, so this helps. Anyhow, they seem to be well built, and I like the storage/charging cartridge.
The sound quality is amazing. They are incredibly comfortable and the fit is perfect. They have not slipped out of my ears once. The touch controls are a bit awkward but the voice controls render them unnecessary. I often wear them at work so I love the fact that the audio pauses if I remove one bud to speak to someone. The battery life has been more than enough for my needs.
