That is honestly impressive. I can confidently say I’ve only owned one wired headset for a decade, and it’s the one I use for gaming so it never leaves my office.
Everything else has either broken, or been lost. Though I fully admit, serviceable wireless buds would be a thing of beauty. IIRC there are people out there actively working on the problem (other than the companies explicitly aiming for them to be a consumable forever.)
Do you mean Calibre?
