FIXED
Found a solution which has worked for me, 

Sounds > Playback > Headset > Properties > Unticked “Allow applications to take exclusive control of this device”

This has worked for me, I havent had any issues as of yet, I will update over the next few days as to any change! Hope this helps at least 1 of you and saves you guys buying a new headset!
(This was only in my situation it may differ)

Seems we are all having this issue rather recently? Ive noticed mine pop and cuts out all sound coming through for a few seconds and on occasion comes back, Ive noticed in my sound settings under the playback tab, it is switching itself between being a default device and just purely non existent? Anyone else getting the same results? Totally considering buying a new headset but love this one! Only recently has this started to happen! Roughly around the same time as OP’s post!

Also having this problem and it is really annoying and also freezes my game when it happens

I’m having this exact same issue and it’s really getting on my nerves 

I’m trying to go through their support and get it solved. But frumSy I know exactly what you mean when you say it switches between being a default device then just vanishing. Hopefully the issue can be solved or it’s a new brand headset for me.

Hi Everyone,

The issue is power delivery. For some reason the headphones aren’t getting enough power. If you connect the headphones to a power dock or a usb hub with power, the issue stops. I have verified this 5 times. Please let me know if this fixes your issue. @Razer Admin you guys need to fix this……. it’s crazy I figured out the issue in an hr what you guys have not in a year…..

Been dealing with this same problem for a few months now every single day. I can keep my head as still as I want and it cuts out. Ive tried using another computer, still cuts out. I think its the wire as when moving it enough it cuts out, Im a couple months passed my 3 year warranty and if I dont find a fix will never buy a product from razer again. 

Having same problem since a few months ago, it’s annoying!! 

    Hey everyone I was having the same issue but was able to fix it. I uninstalled it from the device manager and reinstalled it and it fixed the issue hope that helps. 

Hi, Im having the issue where my Razer Krakan Ultimate Headset keeps disconnecting and reconnecting. I have tried to unistall the headset in device manager just like this last reply says to but it has kept disconnecting and reconnecting it is getting a bit annoying now is there any other way to fix this issue.

I’ve been having issues with my headphone while in meetings! and mostly exclusively with Google Meet, and it keeps disconnecting and connecting like, every 5 seconds, which is awful because I don’t hear shit properly. Which is funny because even seconds before, listening to spotify or watching a video, I don’t have that problem. And it’s driving me insane, I thought maybe the USB port of my computer was the issue, but after realizing this I’m just annoyed and baffled.

Gonna try the solutions offered here and let you know what worked for me I guess.

@greatRoseDustshare895  This is what I used to resolve the disconnecting.

Amazon.com: JoyReken 4-Port USB 3.0 Hub, FlyingVHUB Vertical Data USB Hub with 2 ft Extended Cable, for Mac, PC, Xbox One, PS4, PS5, iMac, Surface Pro, XPS, Laptop, Desktop, Flash Drive, Mobile HDD : Electronics

You will also need a USB-C cable along with a 20w power brick to make sure you get more juice to the hub. This was the cheapest setup I could put together. I tried a dongle but it didn’t work.

If you want something a bit more useful but more expensive you can get a display link hub.

Amazon.com: Dell USB 3.0 Ultra HD/4K Triple Display Docking Station (D3100), Black : Cell Phones & Accessories

This will also allow you to have more than one display if you’re using a laptop.

Nope its happening again, i tried everything but looks like support dosent really care about this problem.
I was a huge fan of Razer, but from now im not gona buy any Razer Products anymore…

Its a joke that they cant figure out and solve this problem.

This headset cost almost 300$ in my country… GG and Bye

There is no firmware for Kraken Ultimate Mr. Support…

You dont even care about us just posting standards bull…..

Hey Guys!

I had the same problem and finaly found solution:

Right click on Razer Central icon in system tray > Click on settings > General menu:

ENABLE GPU HARDWARE ACCELERATION

It worked for me 100% (no disconnecting issue for 2 days now), hope it does work for you aswel.

I have the same problem and you won’t believe it …

ITS THE WIRE !!!  the wire part which is attached to the headset itself, try to touch or move it a bit hard with your hand and you see it disconnects at that moment !!!

as you all can understand, its not software problem, because I uninstalled and reinstalled everything, and after I saw @FlamingxFireball comment, I touched the wire and at least, I know where the problem is.

I have razer huntsman keyboard, kraken ultimate headset, deathadder elite mouse, firefly mouse pad and even razer hammer head, I am even more heart broken when I see no chat of razer supports in here, such big company that says “for gamers by gamers” . now I see that’s a joke, shame is all I can say.

I’ve had this same issue at increasing intervals over the last 2-3 months. If I turn my head a certain way it will pop and disconnect, turning back will pop and reconnect. This was manageable for awhile when it only happened once or twice an hour. But it is now so bad that immediately upon plugging in my headset it pops in and out literally every second - they are unusable. Given various testing of different devices, USB ports, and head-turning angles over the last couple months, it is obvious this is a wiring issue. I’m past warranty and may crack mine open to see if they are fixable. Not concerned about breaking them because they are useless in their current state.

Yeah I’ve had this issue since I bought the headphones. I thought originally it may have been my pc but after upgrading a few months ago this has been continuing to cause issues. I would love a fix for this, but reading the thread it doesn’t seem like it’s going to happen. I seem to be having the issues more when the audio peaks or during specific games. I can play some without issues and others seem to render the headphones basically unusable to the point where I just try a different pair as I lose the sound for such a long amount of time before they reconnect in the Windows sound output settings! 

It’s me again, as long as I live in Iran, repairing fee for any kind of things in the world, is so cheap.

I know if that can be unbelievable, but some dudes, repaired it for me just for 2.7$ (1.800.000 RIALS)

hahahaah, wish you luck lads.

Hello everyone! I also have an issue with my Razer Kraken Ultimate headphones. I have a full Razer setup, and the headphones are the most expensive part, which is why I’m very disappointed in the company. I haven’t used any warranty or similar options because I prefer not to deal with that kind of process. I want you to know that the problem isn’t software-related or anything like that; it’s specifically with the cable that connects under the left ear cup. If you grab the cable and move it slightly, you’ll see that this is where the issue originates. I’m disappointed with the company because they offer high-priced headphones, but these have issues that feel like something from cheap €10 headphones.

This is a very annoying problem considering the amount of money we have paid. I’ve tried every suggestion I can find and still no resolution. 

same issue started happening to me a week or 2 ago. Im just about 3-4 months after the 3 year warranty is up and they seem to disconnect and hurt the living hell out of my eardrums and i only have my desktop audio at 18 (loud for these headphones unlike my old ones that needed 100). Issue tends to happen when hitting the wire near the part that is connected with the headset. Really sad but if its software razer synapse is ass so I dont expect a fix for 5months if it is the software, doesnt even launch 50% of the time when booting.

Same issue here.
It happens regardless of what device it is connected to, so I’m definitely sure it’s the headset’s end that’s causing the problem.
Wire and the conncector tip is in good condition, so I think it’s just a faulty design of the model.

Unfortunate and disappointing because I’ve gotten this headset for my birthday present before and kept good care of it.

During the ‘working’ times, it’s fine; good sound on both input and output.
It’s only the popping issue that freezes my system… very annoying.

my Razer kraken ultimate had some issues lateley. It just keeps disconnecting and reconnecting after a second. Im not shure but it might be because of a faulty cable. it just has a random kink and when i fiddle around with it a little it seems to cause a dissconnect. I cant recreate this to 100% but there seems to be a corelation. Is this a common problem and is there a way to fix it?
