I was about to use them for the first time and needed to change the little round ear buds to the larger size. It is adjustable and I can even wear it over my CPAP machine (sigh), blocks out light and bonus, is comfortable for side sleeping! ngmp677uc But the worst thing of all is the so-called “SUPRO Shock” claim. So may need dual or multicharger cable to use this for charging. ngmp677uc She measured 18cm precisely and fit Size 12. ngmp677uc I am not sure how people are rating this. Update: I seriously love this thing! Grrr ngmp677uc Item was faulty . proved helpful I guess.
