I have it for a month and the battery doesn't last more than 4-5 days, even without excessive use. Of course, it is a Bluetooth device.

It's worth its money. It has good sound and it's lightweight. Only the range should be a little bigger than 15 m. Otherwise, it has been helpful to me in customer service

I use them daily on a computer for several hours on calls. They have very good sound quality and a great microphone that isolates external noises. They connect instantly when using the dongle, I haven't tried them with the computer's Bluetooth. The few times I've used them for music, they have satisfactory sound but nothing impressive. They are compatible with teams, SfB, and Skype, and have been playing without any issues for several months. Their signal is good, but if there are several walls and a distance greater than 7-8 meters, they start to lose connection.

The battery lasts approximately 7 hours of continuous use with talk time and can catch the signal up to a distance of 10 meters. Lightweight.. Suitable for professional use. Not for listening to music

Very nice business headphones, with average battery autonomy.
Be careful to buy them together with the USB adapter provided by Jabra in the package (ask before purchasing at the store).
They can be simultaneously connected wirelessly to both the PC and the mobile phone via Bluetooth, so you can answer calls and listen to music from any source you want without changing headphones.
