@nprofile1q... oh yeah I've heard that Koss' lifetime warranty is pretty good (although several people I know had to use it multiple times, so what does that say about their product durability? ๐) But I haven't had to make use of it.
after getting used to over-ear ANC, plus the lack of devices having 3.5mm jacks... I've only used the
#portapro with
#sailfishos devices from time to time.
