Jabra Engage Convertible Wireless Headset

I have bought and have been impressed by a lot of Jabra's products (several models of their wireless Bluetooth headphones). Having said that, I am hugely disappointed by the audio quality of this headset. It's so bad I initially thought I must have received a bad unit or a cheap counterfeit, but I have tested both the USB-A and USB-C dual speaker (stereo) headsets on two different computers and had the same experience with both models on both computers. Both headsets were updated to the latest firmware version, and all settings were set to the highest audio quality available. However, no audio setting or firmware update was able to overcome some of the worst audio quality I've experienced from a headset - let alone from a headset at this high price. I have tested more than a dozen different headsets over the last couple of weeks while trying to find a solution that will meet my needs at both my home office (my primary work location) and for those days when I have to travel to one of our office buildings. Unfortunately, the Jabra Engage 55 offers some of the worst audio quality of any of the headsets I've tested. I would put it just above the very worst headset I tested, and that other headset was a generic $35 "computer headset for calls." Audio quality from the microphone and headset speakers is, in a word, ABYSMAL. I tested three other headsets priced at less than $50 whose audio quality was head and shoulders above the Jabra Engage 55. I'm honestly shocked by just how bad the audio quality is. I'll be returning these and will, for the sake of my pleasant experiences with other Jabra products, try to forget I ever even tried these.
