I was able to do some research and it looks like the manufacturer does not use different EAN codes or manufacturer numbers for the different batches. In this case, it is unfortunately not possible for us to predict which item belongs to which production run. In any case, you have a manufacturer's guarantee if something should go wrong with the headset.
Unfortunately, we do not have any personal user experience with this product, so unfortunately we have no information as to why a large number of these headsets have been returned.
We have to change suppliers from time to time, which usually results in a price change, but it should never be that big. But a certain fluctuation is normal for this item and is related to availability.
As this question has been asked twice for both models, after researching both, I have the following answer for both headsets:

Mine has been working very well for 2 years and I'm very happy with it. It's better than anything else I've tried with gaming functionality. To do better, you'd need a hi-fi headset, but then you'd need an external sound mixer to separate 'chat/game' and an external microphone. The top strap can be adjusted by screwing and unscrewing, but at the same time, once it's properly adjusted, why would I need to change it? Admittedly it's rather heavy (500g) but I've got used to it and it suits me fine. Every time I try a logitec or razer or other, I run back to the Maxwell, it's really superior, both in terms of listening and the quality of the microphone.
The problem you mentioned could be due to the microphone settings in COD. Try these settings:
First open the game and go to the 'Settings' menu. There you will find the 'Audio and Graphics' tab. Click on it and you will see the options for your microphone. Here you can adjust the microphone level, switch it on or off and specify who should hear you - everyone, only friends or nobody.
Also check the Audeze settings:

I really like the Audeze Maxwell headphones, but it's surprising that not a single reviewer has mentioned the issue with the side tone functionality. There's this annoying crackling sound when there's no audio playing, and honestly, it's unbearable. I reached out to Audeze, and they mentioned it's due to the design of the headphones and considered normal. However, I've never experienced this with even the cheapest headsets I've tried before. I ended up returning my unit, but I'd be open to trying it again if this issue isn't present for you.
