Malt will answer your questions. Hello, landlord.

The biggest difference between these two headphones is that the Plantronics 975 cannot listen to music, while the Jabra Langx 3 can listen to music.

Bluetooth version: Plantronics 975 is Bluetooth version 2.1, Jabra Langx 3 is Bluetooth version 3.0;

Standby time: Plantronics 975 is 6-10 days, Jabra 975 is Bluetooth version 3.0, Plantronics 3 is 11-15 days;

Plantronics 975 is a typical business Bluetooth headset, focusing on sound quality, and the call sound quality is very good.

Jabra Langx 3 is a new product this year. It has a higher Bluetooth version and stronger compatibility. It depends on what functions you need.

Hope this clears up your confusion. If you still have any questions, you can ask me directly. I hope you will adopt them~~~
