(Cannot connect 2 devices at the same time) Review: Very good noise canceling - I use these for work in a loud environment 20-30 hours a week. I can’t use expensive headphones bc they are constantly at risk of being heavily damaged bc of my job, but I still need something to help cancel the noise and I want to listen to music and stuff of course. These have been the absolute best ear bud type in this price range that I have ever used. The noise canceling is very good, the sound is strong, and the battery lasts a very long time. Im about a month in and so far very pleased. Review: Great for the price! - I have been using these earbuds for almost 2 weeks now. The sound quality is great for the price. I love the ear cuffs because I cannot keep the other style of earbuds in my ears. These stay put, even when I have to run for the bus! I have walked through both 90+ hot weather and 50 degrees and pouring rain. They are still going. The case charges them fairly quickly. (I usually charge them a couple of hours before I leave the office.) They last all day. The only sort of complaint I have, is that the button on the earbuds are sensitive, so when I adjust them, they turn off and on lol. ## Features - 【2023 New Bluetooth 5.3】The Bluetooth 5.3 chip and high-sensitivity FPC antenna ensure that the headphones connects quickly and stably within 15 meters, with lower latency and lower power consumption.
