No I'm not, your experience is not universal. I use them consistently between my phone and laptop without issue. I've never really needed to connect headphones to more than 2 devices.
If you're using a macbook you need to ensure you're using the AAC codec, for some reason macOS makes SBC as the default codec for lots of devices and you've to force it to
use the non-garbage codec.
How can you say "No, I'm not" when I've explicitly made the point that the Jabra headset can only have 2 active connections. Just because you've never needed to connect more than 2 devices doesn't mean that this isn't an important distinction for me or others. I literally said "you're either overselling this or only using 2 devices".
