Buying Guide

Bluetooth FM Transmitter

While the market is flooded with all kinds of FM transmitters, not all transmitters are created equal. Some are basic in features, others advanced, some are lookers while others plain and bland, some are low-cost while others are expensive. So how do you choose?

We recommend considering your requirements above everything else. And then there are certain other factors that you must consider:

What Are The Basic Features Of An FM Transmitter?

Access to channels: Your FM transmitter should be able to scan through any empty frequency that can be utilized for playing music. It should be able to do it on its own without your input.

Preset Stations: It should have adequate memory to store the stations. When you have stations stored, there is no need to search for them over and over again.

Charging: The transmitter should offer the ability to charge a device besides playing music through the radio.

Wireless: To the extent possible, the device should plug directly into the adapter or cigarette lighter port of your car. There should not be any wires for the purpose.

Power On/Off buttons: Most transmitters do not come with these buttons. However, availability of these buttons leads to a very significant convenience; you don’t need to take out the device from the socket when you are not listening to the radio.

If the buttons are not there, then you must take them out else they will keep consuming the power and battery without any use. In worst cases, they can even damage your cigarette lighter or the transmitter itself. Hence, we always recommend buying a device that has these buttons.

Do I Need To Be An Expert To Install The Transmitter?

FM Transmitter For Car

No. Most FM transmitters are extremely easy easy to set-up and use. They only need a power source or a cigarette lighter connection in a car. On the other hand, you only need an auxiliary cable to connect them to the audio source. The only things that remains to be done is to simply tune in to the frequency and enjoy the music.

Does The Range Of The Transmitter Determine The Transmission Quality?

Yes, it does. This is why you must carefully evaluate the range capability of an FM transmitter. Generally if the transmitter supports a range of 10 to 30 feet, it is adequate for the reception of good quality signals.

But there are two devices that make for an excellent value-for-money proposition and they are the Nulaxy Wireless In-Car Bluetooth FM Transmitter and the VicTsing Bluetooth FM Transmitter.

However, Nulaxy narrowly surpasses VicTsing with its wireless capability as well as the best LCD display across the segment. There are very few devices in the market that provide good value for your money and the Nulaxy Wireless In-Car Bluetooth FM Transmitter is certainly one among them.
