How to Make my voice audio better with Fifine Plug & Play K668

Hey there i been recording with Audacity for awhile but i wanted to know how can i make my voice sound better in it, i am using a Fifine Plug & Play K668 Microphone to record, but my voice or audio sound abit… low or rusted in the recording? i put the Mic volume about 50-70% to record, but some anyone have any idea on how to fix this with noise reduction, or noise gate? if so please help me.

Please post a short audio-sample …

A short sample in WAV format will be most useful.
