While I do think the AZ80s are the best Technics buds to date, I no longer have them. I do think the Jlabs are smaller and an easier fit. ANC is no slouch. I used the AZs on a cross-country flight and wasn't happy with the ANC. But again, Bose for that, all the way. I'm using the Jlab now and listening to an old Badlands album and Jake E. Lee's guitar sounds awesome. You can def hear the two drivers doing their job well. Separation is great. I agree, vocals are more up front, but it's not distracting to me. All this said, they're cheaper than the AZ80, so if price is important, and you can get the $50 off deal, the Jlab buds are a great buy. Technics are a more premium bud build, but charging cases for both are similar quality. Both excellent. Honestly, none of us here can be the be-all end-all judge. You should test a few out and return the loser.
