beyerdynamic Headband Slider Kit

One of the original sliders that came with my dt990 pros from 2012 cracked within the first year of use and the second not long after. These new ones are going strong after 1.5 years of constant use. The new clips are thicker than the old ones and they come with a little metal ball instead of just a pastic clip to keep the headband on the size adjustment you put it at. I can happily report that after 1.5 year the cans stay nicely in their place, unlike with the original ones. Of course I can't comment on whether these are now baseline on the newer models of the dt990 pros, but if you have an older pair that wont stay in their spot or have broken clips then these are a good upgrade.

The new slider system with the ball seems pretty solid.
The clips seem a little bit different but still plastic. Time will tell if they actually hold up.
I'm not quite convinced they're thick enough to handle the twists so easily applied to these headphones.

Be aware the new clips do not have room for the old metal clamp that press on the headband.

These also do not come with instructions so I had to find a video on youtube. I did not even notice the tiny balls until I saw them in the video.

Edit:
It's been about 2 years now and these clips have held together without issue. There are no visible cracks.
