Install Intel Bluetooth Driver for AADP (A2DP) Headphone

Many people complains about Windows 7 and its Bluetooth support on AADP (A2DP).

If your Wi-Fi & Bluetooth Dongle is from Intel, you can follow the following steps.

1) Install Intel Bluetooth Driver
Currently I cannot find this on Intel website. This will provide you the Bluetooth driver.
Windows 7: http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=K59N9
Windows 8.1: http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=75M5W
Windows 10: http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=N7VN8
You may need to consult your PC manufacturer for this driver.

2) Install Intel Bluetooth Profile
This will provide you some of the Bluetooth profile that Windows 7 fails to support natively.
(Intel calling it Intel Bluetooth Software.) Including AADP (A2DP, Advanced Audio Distribution Profile), AVRCP (Audio/Video Remote Control Profile), Hands-Free Profile.

DO choose the version that is corresponding to previous Bluetooth driver!
For example, I choose 19.0.1603.630 Bluetooth Driver, and 19.0.1603 Bluetooth Profile!

After installing above two driver, you can find two installed programs in your control pannel.
For example, there are:
1) Intel Wireless Bluetooth 18.1.1607.3129
2) Intel Wireless Bluetooth (patch version 19.11.1639.649) 19.0.1607.0648

1607 indicates the release date of the driver. AND THESE TWO DRIVERS MUST BE RELEASED THE SAME DATE TO AVOID BUGS.

Power on your Bluetooth headset, leave it on paring mode.
On your PC, open Bluetooth device panel, add device, choose your headphone.
After adding your headphone, double click the device icon, in the action bar, click listen to music.

5 things you need to do after you purchase XPS13 9350/9343

First, Using Dell Update to update Dell Utility, if you would like. Register your PC in order to have 1 year warranty.

Second, right click Start button, choose Manage, navigate to Device Manager, update the driver of Intel Iris Display Adapter, Firmware, Realtek SD Card Reader, Integrated Camera, and maybe any other component you can find updated driver using Device Manager.
Note: Updating firmware and Iris Display driver will resolve issues about screen flickering, hang-up when wake it from Sleep, noisy fan and other potential issue.

Third, Choose a short non-standard TF to SD adapter, to extend you storage. Otherwise, standard SD card cannot fully stuck into the body of XPS13. Suitable TF to SD adapter is about 9mm shorter than standard SD card.

Fourth, get a Bluetooth Mouse to easy your daily use.

Fifth, get a enclouse. A enclouse for iPad Air 2 may (or may out) swallow XPS13 inside but with a fraction out of the mouth. While a regular enclouse for other laptop may be too large. Maybe you can get a official leather suit for your XPS13.
