T12

Tozo NC20 Pro - 12.5 hours with ANC on / 16.5 hours with ANC off - single charge. $59 on Amazon, and these have all the bells and whistles. If you wanted to go bare bones, the Tozo T12 earbuds have a single charge battery life of 11 hours with virtually no options like ANC/transparency modes. Last time I saw these, they were like $20 at Walmart.

It sounds like you need something with a longer nozzle. Although they're dated at this point, if you can find a set of Jabra 75T earbuds, they should be exactly what you're looking for. They have a nice long nozzle that allows for deep penetration into the ear canal. Another is the Tozo T12. again, they're dated and have no options, but they do go deep into the ear.

I switched to putting iPhone on the floor where it’s cold, or using $30 TOZO throw away ip68 ear buds. Don’t want to ruin my new AirPods seals and mics

Ended up grabbing the aeroclips for black friday and they’ve been great! I’m really happy with how immersive the sound is and how comfortable they are. The color options are a huge plus. If I wasn’t particular about having a choice in color, I think the c50i would be just as great for half the price as they seem to be incredibly similar, design and specs wise. I’m considering getting those as a gift for a family member. But yeah, overall I’m glad I finally got to try soundcore and am very pleased with the sound quality. l’ve had Tozo in-ear buds before and didn’t mind them, but the sound quality was definitely on the muddy side. So thanks for your suggestion! Really helped me narrow down what I was looking for.

Tozo in ear. Cuts out noise, doesn't fall out, cheap enough that if they get damaged they're easy to replace. 

I got them for 21$. They are rebranded Tozos. Sound great but not at 169$.

I haven't tried any of those, but I'm really content with my Tozos. The O2 Open Ear, EarRings, and the new OpenWear are my go to's. Surprising bass and clarity for being open style and the price is unbeatable.

Just picked up some Tozos from Amazon and they are great. I'm also a regular user of Shoks when cycling or running, I've had my pair for 4 years and they are still going strong

Tozos and Earfun have great anc and you'll spend under $75.

I don't typically use one bud at a time so I'm unaware of your issue with that. But I've had Sony and Bose earbuds and I can say that their noise cancelling is not any better and might be worse in some situations versus Earfun and tozo. I've literally had zero issues with the tozo app. Do you have an iPhone?
