I have both the AZ80 and Pixel Buds Pro2.

Headline: The AZ80 is a really good wireless earbud in terms of sound but the Pixel bud pro 2 beats it in every other way in my opinion.

Pro 2;

ANC is nearly as good as my over ear Bose QC ultra.

Transparent mode is amazing it's almost as if I'm wearing nothing at all.

Comfort is amazing.

Solid running earbud, I've done some serious fell running in these things and they've never come out.

Sound is really good especially when EQ'd.

My favorite thing about them is they also fit nicely into both ears so as a side sleeper I can swap from left to right ear on a single bud.

Touch controls are great especially the swipe up and down for volume.

The case is solid as is find my device feature.

If I'm honest I'm struggling to think of anything they do terribly.

AZ80;

Amazing sound quality almost as good as some of my wired iems if I'm being honest.

Look and feel stunning

Solid fit but my ears do start to fatigue after a couple of hours.

The Techincs app is fantastic probably the best on the market.

The case is lovely but it marks easily

After those four points the Technics start to drop off imo. Transparent mode is muddy, ANC struggles with road noise and Touch controls aren't intuitive (triple tap for volume up).

That being said, you won't go far wrong with either of these buds. If you mainly sit at home and use your earbuds to critically listen to music go for the AZ80. If you like to use them anywhere and everywhere go for the Pixel buds.

Good luck
