***Compatible with: Cisco Jabber, Teams, Zoom***I'm sure it's compatible with other softphones and software apps (and can be used with many desk phones too), but those are the 3 I use daily at work. I wanted a high quality comfortable wireless headset, since I'm wearing it around 45 hours a week, and that is what I got.1. It is "plug and play" with the above, I didn't have to go in and manually change my microphone or speaker settings at all, or download anything to make it work properly.2. The level of in-ear volume, when tested, got up to "ear splitting", lol.3. Passive noise cancellation in the earpieces means I can still hear what's going on around me with my coworkers, which is important at my job.4. The noise cancellation in the mic is acceptable but not the BEST. Some background nose is still audible to my clients. I understand that this is adjustable according to the user manual, but I haven't gotten around to testing it yet.5. The mute button on the mic and being able to tap my earpiece to answer or end a call is very handy.6. I have my headset on all day (around 9 hours) and I did test to see - the battery lasts the whole day without having to dock and charge, although it will fast-charge quite a bit if I put it on the dock during my lunch hour.7. No ear or head fatigue even after wearing all day, super comfortable and light.8. I am now free to move around the office and am no longer chained to my desk. I tested the connection and it held all the way to the break room to refill my coffee.*This headset is EXPENSIVE.* I'm not shy about investing in quality when it is necessary though. My last headset was much less costly but died after 6 months, was wired so I couldn't move around much, and wasn't nearly as comfortable as this one - with lots less features as well. So far I am very happy with my purchase. I'll update as necessary if anything changes. I did buy the offered warranty with 3 years of coverage for around $35 as well.
