A:AnswerRange is only 40 feet, according to package. I know mine cut out when I walked into another room, which was less than 40 feet, but there were walls between me and my laptop. I hope this helps.
A:AnswerHello, no this cannot connect to a bluetooth speaker. It needs an operating system such as Windows, MacOS, or Chrome OS.

A:AnswerHi MVC9, Logitech does sell Spare Parts for the H800. They do offer a replacement receiver, but it is currently sold out. You can also contact the customer service team for additional information regarding the receiver https://support.logi.com/hc/en-us/requests/new?ticket_form_id=360000621393 Thank you for being a Logitech customer.

A:AnswerNot without some additional hardware. You could use cell phone and place a call or use messaging apps, but there is no way to communicate headset to headset directly
A:AnswerYes, but you will need to test it with your specific app. Not all apps work, I know for sure that you can NOT do this with Microsoft Teams for example. Microsoft wants to lock you in to their own hardware.
It works very well with Grandstream phones both hard and soft.
