I have gone through many, many call headsets and this is the absolute nicest sounding USB headset I have ever owned. ) Ordered the next size up and did great! I know it has Smartcast by language on the box, but my point is that manual speaks absolutely nothing about it. These earbuds purchased in 2020 for 50$ USDBiggest Pro: Comfort, battery life, price?Biggest Con: Bluetooth connection, BASS heavy?To long didnt read: If the price is right, these will be absolutely good enough. The light brown fit best. Would I recommend these to someone who wants a headset and needs the mic absolutely not. Noise canceling seems to be good as I cant hear anything besides my music. However they could make the sizing easier to figure out on the website so customers dont have to guess. The words "quick" and "easy" on the cover of this cookbook say it all! Surprising? Yes!
