No point buying another until you are happy with how your system works. Microphone faults are VERY rare, and usually are dead - as a description. Your phone is a good example - it really is like somebody complaining their phone makes them look really small and far away, when the problem was they were small and far away, and getting closer or discovering how to zoom was not tried? Buying another phone would not solve it.
