Hi Nothing hardware Engineer,
I have been using nothing for almost 3 years… I have been using nothing ear 2 for a year and I have disappointed with the glue which you are using to stick the stem (cos, when user press on stem, it splits)… I have replace my ear once since it was in warrenty…now again the glue is off and branded service centres are not ready to accept to glue it again… my money is getting wasted…
For atleast nothing ear 4, have round or square tube and attach those with main head which improves durability. Also recommend to use aluminium stem and have round or rectangular cut and add transparent plastic from inside which will increase durability more…
