Pros:- All day comfort- Great ANC Mic- Great sound for calls, music, streaming content, etc- All day battery life- Zoom/Teams integration- Hear your surroundings- Large tactile buttonsCons:- Proprietary charging cable (needed for IP rating)- Wrap around wire extends beyond neckI have own(ed) just about every high end wireless headset/earbuds out there (Bose, Jabra, Pixel, LG, Plantronics/Poly, Sony, etc. For business (MS Teams, Zoom, Etc.)I've tried them all with my laptop and have used Plantronics Savi for years even though it's not the most comfortable.I have used the original Aftershokz Opencomm headset and, although it offered great sound quality and superior mic quality, not having a dedicated mute button was a problem as a business headset. I have to press and hold vol up and vol down to mute and that was clumsy. Plus it muted the headset but not the Teams app itself.When my Plantronics headset started to lose battery life, i decided to try the Opencomm 2 UC. Reason: The Opencomm 2 UC is Zoom certified (and integrates perfectly with Teams).; the UC 2 also has a dedicated mute button on the mic stem; and the UC 2 has a USB dongle.The dongle connection is far better and more reliable than regular Bluetooth connection on a laptop. Plus it provides longer distance (up to 100 feet), which is basically 3X the distance from standard Bluetooth.The mic is as good or better than the mic on the original Opencomm headset, which Id rate as the best ANC mic in the business!The OC 2 has great battery life... It's rated at 16 hrs talk time and 8 hrs listening time. That's important to me because I don't just take Teams calls and Teams meetings, but I'm a software trainer and teach all-day classes online. So, I need a headset that truly lasts all day.The OC 2 also offers multi-point connection. So, I can connect to my laptop and my cellphone at the same time and it switches perfectly when called on. The original Opencomm was multi-point also, but when I went out of range... say, leaving my office laptop and going in my car with the cellphone, it would beep incessantly to let me know the laptop was disconnected. With the OC 2, it simply says, "PC disconnected."Because the "pads" that provide the sound sit in front of your ears and not on on or in your ears, you have great awareness of the sounds around you. However, for that reason, this headset isn't meant to block out sound like on an airplane, etc. although you can put ear plugs in and still use the OC 2 if need be.Music sounds fine (not audiophile quality, but fine). However, at high volume, bass can be more vibration than sound. But I am quite satisfied listening to music or streaming content with the OC 2.Buttons are well managed. Separate up/down volume buttons on easy to find and use; the dedicated mute button is a huge plus; and the multi-function button works fine for play/pause, answer/end/ next previous. Being tactile buttons rather than touch buttons, you don't accidentally trigger a command you didn't intend to trigger.I have only two issues with the OC 2:1. They use a proprietary charging cable. I understand this is necessary to achieve their IP (dust/water rating); but it can be an issue if you travel and forget your cable. For this reason, I bought a couple of extra charging cables (available on Amazon) and keep one in my suitcase and one in my computer bag.2. The band that goes around the back of my head extends out about a half inch from my head. This gets in the way of the back of my office chair, my recliner, and the back of my automobile seat. The work around is to tilt it up higher than it would normally be sitting until it rests against your head. Not perfect, but workable.
