## Questions & Answers

**Q: What is the difference between different model numbers:  eg. 508341,  504576 508342?**
A: All 3 models are working almost the same as sound quality. The difference is the extras accesories in the model packages and PC compatible in the UC models. 

1. Sennheiser Presence Grey Business: (508341) - Dual Connectivity, Single-Sided Bluetooth Wireless Headset for Mobile Device & Softphone/PC Connection. NO USB DONGLE - NO CAR CHARGING ADAPTOR - NO CARRYING CASE. COME WITH JUST THE USB CABLE CHARGER

I bougth  Sennheiser Presence UC model 504576 for reason it came  with all the accessories needed and working with most PC features

**Q: Bluetooth version**
A: Yes. Connects to your phone by bluetooth.

**Q: How do I keep from closing the boom while in my pocket? Effectively turning it off.**
A: I keep mine in my pocket when working in the warehouse. It connects so quickly when you slide the boom out that I've never missed a call. I just did a quick test and from the time I pulled the boom out until it was fully connected and ready to answer a call was less than 2 seconds.

**Q: When connected to 2 devices simultaneously, how do you switch between them?**
A: it is automatic, the phone takes priority during a call over say your computer. if you are talking about between two phones then it would be like a conference call. I recommend answering the 2nd call without the Bluetooth.
