Bests & Worsts Reviews from Amazon

So here's what you need to know about FM transmitters. Firstly, the JETech Wireless FM Transmitter sold here is a nice device - it provides CD quality sound out of your radio. The tuning digits are large and easy to read, and easy to 'tune'. The addition of the USB charging outlet to charge your phone while using it is a nice feature. And best of all, the unit connects to your phone via the headphone jack, which provides a secure and predictable connection. I have used other transmitters that use Bluetooth to connect the phone to the transmitter, but since I'm in my car, that is a feature I do not need and I much prefer the wired connection. So why are there negative reviews about "static" and other issues? The problem is that if you live in a metro area, there are likely no frequencies not in use by "someone". I tune to the 88 series in the Chicago area. But when traveling the 30 miles between my parents house and my own house, I pass through at least four different areas that have "micro stations" broadcasting on the 88 series of numbers. NONE of these stations are listed on the "official" list of FM stations -- because they are too small and low powered. So what is the result? Static when passing through these areas. But since I know what is going on, I sit tight and wait until I am beyond the range, and my music comes back crystal clear. The 107 series of stations is also available on this unit, but ALL of the 107 stations are in use in my area, and all are on the official list of FM stations, which means they will be more powerful. So what is the best way around this? Well, all FM stations use ODD numbers, so 88.1, .3, .5 etc. However, this device also allows you to select the even numberes, such as .4 and .8. If you have a tuner that has a manual tuner capable of tuning in the even numbers (mine does not) then you can tune into the even numbered stations and enjoy digital quality sound uninterrupted. Note most newer FM tuners do not have the option to tune in the even numbers, but some have a way around it. If not, you can still just wait out driving by the micro stations or make your selection carefully when choosing a frequency to tune in. But don't blame this transmitter, blame your local micro stations.
