2. Sound Quality Matters to Me

For me, clear audio is one of the most important features. I look for a transmitter that reduces static, background noise, and signal interference. If I can hear music and phone calls clearly, I know the transmitter is worth considering.

3. FM Frequency Range

I always make sure the transmitter offers a wide FM frequency range. This helps me find an open station with less interference. The more stations it supports, the easier it is for me to get a clean and stable connection.
