Review on Samsung Galaxy Buds Live TWS Earbuds with Active Noise Cancellation, Bluetooth 5.0, 12mm Drivers, Compatible with iOS & Android - SM-R180 (Buds Only, Mystic Blue Limited Edition) by Chun Chun ᠌

Overall, excellent headphones. These look fantastic and have excellent battery life. Although you might not detect it, the noise reduction does exist and blocks out lower frequencies, I believe around 500 hertz and down. It can be used as earplugs, the ears rest directly from low-frequency noise, which you might not even notice without them, puts a lot of pressure on your hearing and your head in general, and from which your head starts to hurt. This is according to my personal observations)) and at the same time quiet you can hear everything that is happening around you and what they are saying to you)) It works perfectly with my iPhone when I use it. I don't regret buying these at the current price, and I believe that many more expensive headphones will generally be worse than these.
