Okay all, looking for some help here...something got messed up with this latest Win 10 update. Everything was PERFEFCT yesterday (before the update) and today, not the same.

After HOURS of working on various solutions, I got my Bose QC35ii to reconnect to my PC and have semi-proper sounds. The Bass, Mids, and Treble overall sound fine and as they should. However, now I hear mild static and poor syncing along the way. When I connect to my phone and listen to the SAME YouTube Video (for troubleshooting and to stay consistent) they sound GREAT! So the issue has to be with the PC. Any ideas?

【Bluetooth 4. 0】 – applies the latest Bluetooth 4. 0 and it is backward compatible
BT 5 is latest, its showing its age.

chipset is Windigo BTM01C2AC but i struggle to find who actually makes it. Drivers should give me a clue.

https://en.wikipedia.org/wiki/CSR_(company) makes chip

CSR 4 USB Bluetooth adapter does not require any driver other than what is included with the Windows 10 operating system.

so that shouldn't be reason. Although it makes me wonder as an update stopped it working, that sounds like a driver update to me.
curious what driver version it shows in device manager.

The QuietComfort 35 II headphones are inbuilt with the Bluetooth version 4.1.

Bluetooth 4.0
When Bluetooth 4.0 was developed, the upgrade boasted a number of additional features like improved connectivity and range. However, what is most advantageous for audiophiles and really anyone especially interested in the internet of things is the Low Energy protocol.

Bluetooth 4.1
Bluetooth Low Energy protocol means you can rock your wireless Bluetooth headphones a lot longer. Bluetooth LE allows smart devices to remain connected for longer periods of time without draining the battery. Bluetooth 4.1 took LE to another level. The 4.1 technology, which is currently featured in headphones like the MEE x7 Plus earbuds and others, can better manage their power and that of the device they are paired to by automatically powering up and down based on a power plan. Older versions of Bluetooth technology often interfered with other wireless technology, like 4G LTE communication, but the latest development was also made to fix that problem.

What motherboard do you have? funny your sig includes everything else.

does it have BT onboard or are you using a WIFI/BT adapter card?

Thank You! I will look into these links and see if any work.

As a quick update, I tried to connect with my older Soundlink Headset and it works, PERFECT...just lower quality headphones, but still from BOSE.

Also, as sound is hard to describe without recording and posting here...I was thinking while out in the Deer Stand this morning, it almost sounds as if it is using a slower/incorrect bitrate, if that makes sense. BUT only started AFTER the latest Win 10 update AND only with the QC 35's

Okay, this all got me thinking, especially the part about the update and driver issues....I have been messing about with this for DAYS now and with your help and direction, IT WORKS! I went into the Device Manager and removed the Bluetooth Device, along with any Drivers/Software it used. Naturally, that put me back a little bit as I had to find new drivers and that got confusing. However, after getting the Bluetooth Driver Package from Microsoft and installing, rebooting, replugged the Dongle...BOOM it worked, and better than ever!

THANK YOU!
