I have used Plantronics brand earpieces for about ten years now and I have been happy with them.What I liked most about the Plantronics was the battery life. I could listen to music for the entire day. The sound was acceptable for someone "at work" rather than and audiophile sitting in the dark listening to whatever genre of music floated my boat.Well after using one, day in and day out, for three years the battery began to last less than the eleven hours that it used to.So I bought one of these strange name brands and had equal success until after about a year people began to complain I couldn't be heard that well on calls.So I tried to shift to earpads. I tried several. Some for around thirty bucks, some for around ninety bucks, but while they were great at playing music and cancelling ambient sound, when making calls I still was told my voice was too low, or distorted or tinny.After trying around eight different styles and brands, I decided to stop wasting money and just go for a single ear piece like I used to have.The first "Indian one had done OK and so I thought I would push the boat out and spend forty Buckaroos on this one.I received it and the battery life is AMAZING.The sound when listening to voice, music or calls is great!And even better the people on the other end of the calls say they can hear me loud and clear.I tell you I tried so many others and tested the voice pick up during calls by recording my voicemail message using the headset. This little gem beat the pants off everything else. Even the exotic brand like Blue Parrot sounded awful in comparison.I like this because it doesn't sit inside the ear canal and so you are aware of what's going on around you.If I want to have full noise cancelling on a plane for instance, I pop in a pair of the earbuds and relax.There are even Bluetooth transmitters you can plug into the aircraft headphones port so you can be wireless and listen to your entertainment.Speaking of which there seems to be just a fraction of latency when I connect to my smart TV or the ROKU with this headset. I cant believe the quality and battery life you get with this wee fella.USB-C charging port, multiple ear grommets and a nice case!
