Given its thickness, I believe this case can last a long time. Sound is great, comfort is acceptable, build is good, except for the typical delicate cord. My cap rack was a little unstable as I used the dip station attachment but not too bad. It might be wise for Amazon to check the box to be sure the correct product is inside as the box says they are the black/berry color, but thats not what I received. Great headset for gaming. ), these have a little bit of more closed-off sides. This is my 2nd time ordering?? The other reason I purchased this product is it?s one of the few that will do 15W charging on the iPhone. My iPhone 12 charges but my apple watch SE stops charging after a couple of minutes. when these eventually die, i would definately buy sennheiser again.
