i bought new apple headphones (earpod).
I noticed the microphone doesn't work with androids phones , but it works correctly with samsung galaxy s2 and apple phones ( nathurally )
when it works I misured the power voltage , it is 2.2 V , when it doesn't work it is 1.5 / 1.7 V .
Is it possible to modify tension level ? Or is it fixed by hardware ?
