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.
https://downloadcenter.intel.com/download/26421/Intel-Wireless-Bluetooth-Software-for-Windows-7-?v=t
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.

Good to know: XPS13 9350 comply with USB-PD standard!
Good to know: XPS13 9350 comply with USB-PD standard!
So you can charge your laptop with a USB-PD compativle USB-C charger.
Like Google Universal 60W USB-C charger (which is quite enough), or future 3rd charger.
But a regular 5V USB charger won't charge XPS13 9350 at all.
Becuase both voltage and amp are too low.

Alright, so I made an account finally just so I can answer this question for you and help anyone else out who has been researching about this. I just received my new Dell XPS 13 about 2 weeks ago and before that and up til today I am still doing a lot of research on charging with USB C. It looks like the charger for the Dell XPS 13 is a 45W 19.45V/2.31A charger. That means the charger you use for USB C charging has to be +/- 1V than the standard 19.45V. The amps has to be 2.31A or higher, just as long as it is the proper voltage (and polarity but that's another story and USB does bother with polarity from what I've heard). So in this case, you and me both have to look for a USB TYPE C charger that supports at least 19.45V/2.31A. There is one charger that I know does this...it is the Chromebook Pixel 2 charger. It is 60W at 20V/12V/5V/3A. I ordered one and it will be here on Monday, I wanted to have a universal charger for my laptop and phone (Nexus 6P). Since it supports both outputs for my 6P and XPS 13 I bought it. I got the same issue "plugged in, not charging" when I tried using my Nexus 6P charger on the XPS. I knew it wouldn't work because the charger is 15W at 5V/3A but I just wanted to see what it would say.
I have literally been researching this for weeks, and I think the Pixel 2 charger will work (I do not see why not since it can support 20V/3A charging). I also heard about a MacBook charger being out there but I did not bother to look into it, all I know is that it is less watts but do not know about the volts or amps. I am only worried about issues arising from using USB charging rather than the standard charger, companies usually create their chargers to be the best and most exceptional for the device. Wondering if it'll hurt battery life in the long run.
A little knowledge about Watts, Volts, and Amps: So after much research I found that watts = volts x amps. Volts are the power pushing out of the charger. It is OK to use any wattage as a charger but you have to make sure that the voltage is +/- 1V around the standard for the device requirements. In this case, 19.45V (XPS 13) will be safe with a 20.45V or 18.45V charger. Amps are the amount of power the device actually draws in. In this case we need AT LEAST 2.31A to receive a standard charge for the XPS 13, anything less will cause a slow charge. Same goes with our phones, some chargers output a standard 1A but there are some quick chargers that put out 2.1A, these double the charging speed (I do not know if this is bad for a battery though, nothing ever happened to my Nexus 5). I think the amps are regulated by the XPS so even using a 10A charger would only work at 2.31A being pulled by the XPS.
I won't be sure about this stuff until I receive my Google charger and test it out this week, if it works I may even buy another one. Hope this helps out!
UPDATE: Ok, I just received my Chromebook Pixel 2 charger that I ordered from Google and I can confirm that it does charge my Nexus 6P "rapidly" and it also charges my Dell XPS 13. I plugged in both chargers separately to compare the "time left to charge" and both read the same time so I am assuming the charger is working similar to the Dell charger.
UPDATE 2: I just ran a battery software (batteryinfoview) and I can confirm that the voltage running through the chargers is the same and the estimated full charge time is the same as well. So, the Google Chromebook Pixel 2 charger WILL work to charge the new Dell XPS 13. Hope this helps other people! If you have a new Nexus device or new TYPE C device and also have an XPS 13 get this charger. (20V/12V/5V/3A)
UPDATE 3: Ok so it's been about a week since I have been using my new charger. While it works great on the DELL XPS 13 I am starting to notice some weird stuff when plugging in the pixel charger into my Nexus 6P. The charger registers perfectly on the XPS with a 10 second delay (this is usual). But sometimes when I plug it into my phone it doesn't always display "charging rapidly" sometimes it shows just "charging." I do not want to say I have a faulty charger but I am going to see if Google will send me a replacement just to make sure it is the regulator in the charger and not my phone. I am assuming that since the charger can provide three different outputs of power, the charger gets confused when switching it into my phone sometimes (which is weird because they're both Google products). I even used an app to monitor the amps being pulled from the charger, when it just says "charging" it is pulling about 500mah-1000mah. When it is "charging rapidly" it is pulling 2000mah-2500mah. The rapid charging is ALWAYS supposed to be on because of the 5V/3A output in the Pixel 2 charger (by the way, both the Pixel 2 charger and the Nexus 6P charger provide 5V/3A). I never have this issue while using the charger that came from my phone, considering it only provides 5V/3A compared to the Pixel 2 charger that outputs 20V/12V/5V/3A. I am either going to assume the charger is faulty, or this is just how the chargers are made (not designed well for other devices other than the Chromebook Pixel 2).
So you can charge your laptop with a USB-PD compativle USB-C charger.

Q:
I just got my new XPS 13. A Dell sales rep told me I would be able to charge the laptop through the USB-C, so I got this cable http://www.amazon.com/gp/product/B010VFFSL4
When I plug it into a USB charger, I get a "plugged in, not charging" message.
I have used the cable with this http://www.amazon.com/gp/product/B00OQ19QYA , the wall charger that came with the LG G4 and an external battery pack, all with the same message.
Has anyone had any luck charging with USB-C?

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.

MacBook Retina 12" can be charged using normal USB charger!
Chinese version click here. 中文版本(点我 传送门 )。
Recently I was curious about this. Since Macbook Retina 12" use USB Typc-C interface to charge, and the rated supply voltage is 14.5V 2A (USB-PD) or 5.2V 2.4A (clearly output voltage is a little higher for cable compensation),and Apple claims "Your MacBook will charge from USB-C power adapters not manufactured by Apple if they adhere to the USB Power Delivery specification." on this page. So I wondered, whether I can use a normal USB charger plus USB Type-A to USB Type-C adapter to charge MacBook Retina 12" or not.
Since Apple won't tell you the technical detail of Mac, so there must be some brave guys to test for us. Luckily I found some tests on the Internet.
You can use Apple USB-C 29W charger to charge Google Chromebook Pixel, but you WILL suffer a lower charing speed, since charger can only output 29W of power.
Left: Google Universal USB-C 60W Charger compatile with USB-PD.
Right: Apple USB-C 29W Charger compatile with USB-PD.
An intersting fact was showed. While your Mac is in NORMAL CHARGE mode, the charge icon is different from that while charging in SLOW MODE.

Since Apple won't tell you the technical detail of Mac, so there must be some brave guys to test for us. Luckily I found some tests on the Internet.
TL;DR: You can charge Macbook using normal USB charger.
WARNING: Compatible does NOT mean reliable or safety. You should use a USB-PD compatible charger with enough rated output power to charge your Macbook Retina 12" (e.g. Google Universal USB-C 60W Charger). Charging Macbook Retina 12" using a low power-output charger may result in over-heat in the charger, even fire. Charging Macbook Retina 12" using a fake/conterfeit or low-quality charger may result in danger of electric shock or fire or permanent damage to your MAC. I TAKE NO RESPONSIBILITY OF ANY POTENTIAL DAMAGE OR ANY INCORRECT IMFORMATION IN ANY CASE. TRY IT AT YOUR OWN RISK.TEST ONE from notquitemainstream.com (English)
You can use Google Universal USB-C 60W charger to charge your Macbook, but you will NOT benefit from a larger rated power (60W), since Macbook only takes 29W.You can use Apple USB-C 29W charger to charge Google Chromebook Pixel, but you WILL suffer a lower charing speed, since charger can only output 29W of power.
Right: Apple USB-C 29W Charger compatile with USB-PD.
TEST TWO from ChongDianTou.com (Chinese)
You can use a 3rd party Standard 5V USB charger to charge your Macbook Retina 12", but you WILL suffer a lower charing speed.An intersting fact was showed. While your Mac is in NORMAL CHARGE mode, the charge icon is different from that while charging in SLOW MODE.
Charging using offical USB-PD compatible USB-C 29W charger.
Since power conversion efficiency is lower than 100%, so input power is 31.8W.
Charging using a 3rd party USB 5V 2.1A charger with USB-A & USB-C ports.
(USB-PD not compatible, JUST normal charger plus a USB-C port)
Macbook cannot determine this 3rd charger, so it take only 5Vx1A=5W.
5V 1A is kind of standard spec, in order to insure your safety.
The power efficiency is lower than 100%, so input power is 6.58W.
Here is Mac icon for NORMAL CHARGING and SLOW CHARGING.
TEST THREE from bbs.feng.com (Chinese)
This brave man try using iPhone or iPad charger to charge his/her Macbook Retina 12". It turns out that you can charge Macbook Retina 12" with a normal USB charger which is not compatible with USB-PD.
Charge Macbook 12" using iPad 5.1V 2.1A charger.
Since power conversion efficiency is lower than 100%, so input power is 13.8W.
Charge Macbook 12" using iPhone 5.1V 1A charger.
Strange enough Macbook only take 5V 500mA. Maybe the iPhone charger is too old for her to recognize.
Since power conversion efficiency is lower than 100%, so input power is 3.2W.
Anyway this power is too low, and dfinitely will not effectively charge Macbook while OS X is still running.
CONCLUSION: USB WILL ALWAYS COMPATIBLE WITH 5V FOR BACKWARD COMPATIBILITY
No matter what USB will advance in the future, for safety, for backward compatibility, USB will always compatible with 5V. Remember if USB output a voltage other than 5V or a current higher than 1A, the host and client must comply with some sort of standard, like USB Battery Charging, or USB Power Delivery, or Qualcomm Quick charge 1.0/2.0/3.0. THE INITIAL AND DEFAULT PROFILE WILL ALWAYS BE 5V. If it is not designed like that, you can easily burn your device into fire. Of course, old charger rated with lower outut power, and you should not use a low-power charger to charge a power-demanding device in the normal case. But imagine, that you didn't bring your charger along with you, and don't worry, you can charge it using a normal USB charger to help you out. That's wonderful. Also, you can buy a new full-spec high-output-power universal USB charger for any USB devices.
Of course you are recommended to use official charger.
If you want use any other charger, you should know what you are doing.
IT IS A BIG STEP, THAT ONE PORT WILL SUPPORT ANYTHING!
Not far in the future, you will need just a single full-spec USB charger to charge your notebooks, mobile phones, tablets, power banks, and more.
