BlueParrott S450-XT Voice-Controlled Bluetooth Headset with Industry-Leading Noise Cancellation – Long Wireless Range, 24-Hour Battery Life & Comfortable Over-Ear Design for Truck Drivers, Call Centers & Remote Work (Black)

Excellent stereo headset. I am a lawyer who telecommutes 100% of the time. Particularly during COVID, I noticed that I had better, less tiring and easier comprehension on phone/Zoom calls when I used my Apple earbuds - - because I was using both ears. As opposed to my then phone operator style single ear Blue Parrot headset. Our brains comprehend best when we hear with both ears!So I then bought these (only two ear version I could then find of Blue Parrot) and have been very pleased, in fact have bought three of them (for two locations and to replace one I broke).Bottom line is I hear extremely well with these, and adjacent noise (children) does not come through. I have recommended them highly to business acquaintances who have been similarly impressed.Comments: If you don’t flip the mike boom down towards your lips folks can’t hear you. That’s why they are called noise cancelling! They emphasize bass frequencies more than mid-range (which is where the intelligence in speech comes in). So people’s voices sound lower than they do in person - - Once dealing with a CSR with a very deep voice I had to switch back to my earbuds. Have not tried the app or tried to program them, work fine out of the box. Have not used them with music, in part due to the high bass, but that is not what I bought them for. Long battery life. Large and comfortable, size is why I bought a second one to use at our daughters (largish for travel, esp if you are traveling carry-on). Be gentle with the on-off switch, which is what I broke after three years.Highly recommend these.
