Summary: Works with Bose ultras out of the box, no driver needed. Voice also works. Only negative is the idle light that is too bright. Would reconmend.
I know my review may come unnoticed, but on the off-chance anyone also have a pair of Bose ultras I would like todo you a personal service: I can confirm that it works with the Bose Ultra without any driver install. Voice also works. I've even used this on a older pc without any default / built in bluetooth with little problems. What really peaked my particular surprise is how I am able to charge my headphones while I use these with bluetooth. Only a few of my devices allows this, glad to have my personal computer tobe included onto the list. For those that got stuck like I did, here are the steps that I've done below,
Step 1) Connect the usb dongle and mic. Wait to see UGREEN pop up in your Sound settings. Make sure it becomes your default
Step 2) The sound will be at 100 here. Do your eardrums a favour and make it a lower volume. Thank me later.
Step 3) This is where people get confused. I know, it usually takes a few seconds or a single click to connect to any bluetooth device. Even newly connected / paired ones. This time you'll need to hold onto the button until you hear “ ready to connect “, which takes about 10-15 seconds. Never knew this was a hard connection function until today. For whatever it is worthwhile to know I only had todo this once and now my Bose ultras recognize the dongle wit ha single tap since then.
Step 4) Enjoy. Simple enough, right?
I currently live in a three story house with my computer on the highest level. I'm able to listen to my pc while I'm in the basement with metal ducts between myself and the dongle while doing my workouts. This is with Silent or Immersion mode enabled. I believe that would be the APTX adaptive codec in play, as my other bluetooth devices had issues. My only real gripe is how bright the led light is on it's idle mode. So I would recommend placing the dongle on your pc where it won't blind you. But that's defiantly a first world problem and something I can tolerate, especially considering that the other dongle that I was about to purchase was double this in price post taxes.
