Liberty 4 NC

I have not experienced this, but the sound did go kinda flat...I replaced the ear tips and now have a better seal. Foams help a lot, for comfort and SQ.

I can recommend liberty 4nc. Compared to airpods 2 the sound is a bit more bassy, and the quality is just a tiny bit less. And the nc is not on par but still, the 4nc is great!

Don't know about other buds you mention. But definitely avoid 4nc. It's pretty decent sounding, but forget comfort. After 1-2 hours, your ear will sore badly. The chassis is bulky and protruding inside your ears. I'm using liberty 5 currently and am pretty satisfied with it. Still comfortable to use after a few hours. But it's quite more expensive.

eartips arent the issue. Its the shell. Its bigger than average people ears. If you have big ears, i supposed you find it ok. But so many people report the same thing with 4nc. Its just not for long usage.

Earfun!!! Liberty 4nc has weird fit

Using liberty 4 NC for a while now. ANC is solid and battery timing is amazing. I would recommend these over others.

i have enco x3i. anc is amazing. i ride train every weekend. no complain from my wife. we usually on call for 6 hours while i was on train. my voices are clear but huawei freebuds pro 4 is better. trains noise factor is higher than busy street noise. oppo enco x3i = oneplus buds 3 (same product just different name) i bought huawei for 127usd and oppo for 67usd. i have also use others such as buds fe, liberty 4 nc. not good, voices are not clear. buds fe received very high rating for phone calls in rtings.com, but imho avoid, its bad. i bought 2, believing online review are dependable. on my search for clear call, now i owns, 2x buds fe, enco x3i, liberty 4 nc, buds pro, fiio utws5, 2x huawei freebuds pro 4. (so far huawei 0 complain) 🤣
