I think we all agree with the statement. I think for sure the q30 and q35 need to have a metal strip to take more of the force from the plastic part.
Either that or they need to redesign the shape of the headset or make the strip fully metal. It is why I tend to stay with earbuds more than headsets but do like a good headset to use ever so often.
The Strike 1 that I think is a failure for gaming headsets for Soundcore had a worse issue than the q30 n 35. The sliding band was a lot thinner and wider. So from my experience, they broke due to the stress from wearing them at the same area consistently. (and now you do not hear anything about them anymore). Overall they were a decent gaming headset but several other gaming headset had the same issues. ( will say my favorite gaming headset was the p11 from turtle beach. It last like 5 years or so and I only tossed them after the electronics had issues)
