To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I have used Jabra USB speakers for years. The previous models (with a USB wired connection) held up petty well until 2020 when apps like Webex would glitch out intermittently. So decided to upgrade to the new 720 as I could connect via Bluetooth directly to my phone or my laptop.
Unfortunately, the new 720 does not work well for over half the calls. It struggles with computer over audio with Webex (creates an echo for all the other conference attendees), so I dial in over the phone to for audio - even then, the speaker gets "confused" when toggling Webex to mute/unmute. It also sometimes just garbles the sound. I have had to drop out of far too many calls and rejoin using just my iPhone - it makes you look unprofessional to colleagues and customers.
I'm debating whether to return or to keep the speaker. It does pretty well, as just a speaker for listening to conference calls where you don't need to speak, or toggle between mute/unmute - though even then, audio has dropped a few times after about 45mins.
Finally, from my laptop, I cannot get it to play audio for videos that I play through a browser, which is a big issue.
