I have both and I find the Buds 4 to be inferior.
Battery life seems worse on the Buds 4 but more importantly the audio quality on the 4 is not as good as the Buds Pro3. Buds 4 sound a bit tinny and not as immersive as the Pro3.
Lows, mids, and highs all seem a bit congested on the 4 compared to the Pro3.
When I put on the Buds Pro 3, it sounds damn good. When I put on the 4, it sounds just ok.
If you wanna go on a budget, the oneplus buds 4 seem to be well rounded under $100.
If you want to spend more, Technics AZ 100, Noble Fokus Rex 5, B&W Pi8, Soundpeats H3 are more focused for their sound but other features are weaker.
If you're using an iphone, might want to consider the Airpods Pro 3.
Huawei Freebuds pro 4 are well rounded.
Edit.
Other well known buds are Sony XM5, Sennheiser Momentum 4, JBL tour pro 3,
I see. I have the OnePlus buds 4, Earfun Air pro 4, Soundpeats H3, Bose Quietcomfort 2024.
The ANC on OnePlus Buds 4 is quite good. Not sure about the tube though. My usage is more towards office noise. The ANC works great with office noise.
But the best ANC among the 4 earbuds is Bose Quietcomfort 2024.
I bought these on trial to possibly replace my Pixel Buds Pro 2, and my PBP2s have been sitting in a drawer ever since. These fit better, sound better, and ANC works better for me (probably has to do with the better fit as well) - SERIOUSLY impressive. The only software feature I miss from the Pixel Buds is the low volume EQ thing, and the only hardware nitpick I have with the Oneplus buds is that the case feels a tiny bit flimsy. But they are 100% my go to recommendation when people ask me what earbuds to buy at this point.
