Soundcore by Anker - Life P3i

I use Anker soundcore life p3s, ive had them for over a year and I use them all day in a noisy shop. They have good sound quality, decent noise cancellation, very comfy, and the battery is still going strong. Lasts like 2-3 days on a single charge. They have newer models now too which might be even better.

Not a top contender in ANC. Even my cheapo Anker Life P3 have way better ANC than my new AZ100. For audio and comfort, AZ100 is killer though.

I thought so at first so I also tried Dunu S+S and Spinfit W1 tips in my size. The Spinfit work best for a proper seal on these for me, but the ANC still pales in comparison to the Life P3 and both are worse than the WH XM4.

Earlier today I was in a train and walking in the city center - lots of noise was coming through. Now in my condo it's definitely neutralizing street noise 20 floors down (which is not loud to begin with) so it's working. I've noticed the AZ100 seem to work in a smaller freq band than the Life P3 and WH XM4, but in that band it works well. Outside of that band like when I was on the train and it let a bunch of that clatter through. I'll keep your recommendation of repair/replace in mind.

Soundcore P3i and P20i. Good buy, good battery life, effective noise cancellation, app works well on iPhone. Inexpensive enough that there are no tears or rending of clothes if you lose one
