Anker Soundcore P30i Review
Background
I bought these earbuds as I got fed up with getting through Apple Earpods (the wired ones), and Lightning -> 3.5mm adapters at a rapid pace. Maybe I am just clumsy/careless but they rarely last more than a couple of months for me. I chose the P30i as they were cheap, from a brand I knew and had noise cancellation.

Review
Comfort
At first I found them uncomfortable but after about a week
that has worn off. I can now wear them for hours without
discomfort.
Note that the initial discomfort was likely due to having
never used IEMs before, rather than these specific
headphones. For someone used to IEMs, they likely wouldn't
experience even the initial discomfort, although everyone's
ears will be slightly different.
Sound
The sound quality seems very good, it's no worse than the
Apple earphones I was using before, which I considered to
have pretty good sound.
A problem with the sound is wind noise. If there is any wind
at all, or even inside when you are walking quickly, you will
hear the air rushing. Maybe this is just a feature of IEMs,
but it's pretty annoying, and I end up wearing a buff around
my head when out (which I did sometimes anyway so it's not a
huge deal)
Battery Life
Initially the battery life was very good, I never measured
it precisely but it was in the range of 5-7 hours per earbud.
Over time this has degraded a bit, with the earbuds now
giving about 4-5 hours of battery life each. Considering they
have had 300+ charge cycles this is pretty decent.
Regarding the case, I normally use only one earbud at a time,
and swapping them into the case, with about 10 hours of use a
day, I can go for 3+ days without charging the case. A USB C
connector is present on the case for charging.
Noise Cancelling
The noise cancelling is pretty good. As they are IEMs there is a default level of sound isolation/cancelling, due to the seal they form in your ears, and the ANC on top of that makes them a lot more usable on a loud bus for example, than my previous Apple wired Earpods. As mentioned earlier, the wind noise reduction doesn't seem to work at all however.
Other
The case itself is decent quality, the bottom of it is
very scratched but that's inevitable with plastic,
and I haven't been delicate with it. I did experience some
charging problems a few months back, but I cleaned the
contacts and it has been fine since. Regarding connectivity,
the Bluetooth works well, I can walk across my house, or out
of my Uni room and into the kitchen, and they will stay
connected (to my iPhone 8 at least, other devices aren't
quite as good).
I wear them in the shower but I always take them off
before washing my hair/head, so they aren't in direct water.
Been doing this for about a month and a half and they are
still fine.
