How to Choose the Best FM Transmitter
Let’s see together what are the features to consider to choose the best Bluetooth audio transmitter! In this way, you will be sure to choose a model that is really useful for your needs and does not disappoint you.
Size of Bluetooth FM Transmitter
The first factor to assess is the size. Some models are obviously larger and more bulky than others, so we advise against those who are instead looking for greater practicality. You will definitely prefer a more compact radio transmitter. Now on the market, they find models so small they can fit in the palm of a hand, and that can therefore always be carried in a bag or even in a pocket!
Obviously the dimensions will also affect the display. It is important that it is backlit, so you can read it easily even at night avoiding too many car distractions. The size of the display, in turn, influences the number of information that you can display on it. The basic models are limited to standard information, such as the frequency and status of the battery. Someone else also adds the indication of the volume, the AUX source (USB or SD card) from which the music comes, even the details of the song being listened to and any incoming calls, if connected to a smartphone!
These more detailed models are obviously priced higher. It should also be considered that if you plan to use your FM transmitter while you are in the car, you will have little time to read all this information with each new song being played. Safety first! So make sure you buy a model that is large in amount required for your needs.
If you are a technology enthusiast, it will be really easy for you to approach these tools. After all, their operation is really intuitive and basic. Otherwise, you may also want to evaluate the ease of use of your new Bluetooth FM transmitter. However, these are not devices that are too complex to use, so just look at the instruction manual to be ready to use them immediately.
Older models need to be inserted into the cigarette lighter, which then becomes their power source. The newer and smaller models, instead, are equipped with an internal battery, and are therefore much more practical: simply connect them to your smartphone or your music player. However, even for these models it is possible to recharge using the cigarette lighter, purchasing a special 12 V connector. The latter is not always included in the case of the more recent models. Buying it later involves a very low investment, you probably already have a cable like this in the glove compartment of your car!
A good idea is always to check that the upper part, especially in the larger models, is articulated. It will certainly be easier to connect them by finding immediately a place to place them and that is suitable for your needs. It is important that the cable is not bent unnaturally, otherwise the connection may not be perfect and could be ruined in a short time.
As for the keys, they are generally few and decidedly intuitive. Surely the symbols drawn on them will make you understand their function right away. The most essential models, among other things, have only two buttons, and are therefore perfect for those who are fast on technology or are simply looking for a product that is very fast to use even while driving. By now on the market it is easy to find models that are even equipped with a very comfortable remote control, for a remote control that will surely offer you greater safety while you are at the wheel.
Performance is definitely last but not least. They depend on various external factors on which you cannot intervene, such as the quality of your car radio or the audio system of your car, but also a possible crowding of the radio antennas that makes the signal less clean. This is obviously a risk to be taken into greater consideration if you live or drive in very crowded cities. But even in the open country, there may still be problems with reception!
Beyond these factors, to get an initial idea of the quality of a Bluetooth FM Bluetooth car transmitter are three: study its packaging, read reviews from other users, and seek expert advice. These three things will certainly give you a general overview and will help you understand the quality of an FM radio transmitter beyond the prices shown, which do not always equal its performance.
What is important to understand, when evaluating the purchase, is first of all how stable are the frequency and possible Bluetooth connectivity. This association should ideally take place very quickly, without any problems whatsoever. In some models, it is even automatic, and an item will be reproduced by your audio system to alert you of the operation.
Now you know all the information to consider before proceeding with the purchase. Remember not to be immediately conquered by any very cheap prices, but always to evaluate the technical characteristics of each model and its compatibility with your needs. At the same time, a very expensive model could be such only because it contains accessories and features that you would actually end up not taking advantage of.
Now let’s see how to get the best out of your new Bluetooth car transmitter! Much of this information is very basic, but it can really make a difference!
As already mentioned, these devices allow you to freely listen to your favorite music in the car, leaning on the songs saved on another device or played by music software such as Spotify. This is really a great convenience, which makes you much less a slave to radio and now very intrusive advertisements. If you prefer, though, you can also use them to listen to radio stations or podcasts.
The operating principle of these devices is very simple, but certainly effective. They exploit the free FM frequencies to be able to reproduce, through the car radio installed in your machine, the music being played on other devices connected to them. The heart of the operation lies in Bluetooth connectivity, which allows all these devices to communicate with each other.
Unfortunately, the only problem, as well as the great limitation of these devices, is the number of free FM frequencies in the area where you are. In large cities, therefore, it might be much more complicated to find a free sequence, or in any case the connection may not always be crystal clear and stable.
If your model has more connections, it’s better to use them all. So you can play the music saved on devices connected via Bluetooth, but also USB or maybe you can also take advantage of the slots for micro SD memories! Then read the instruction manual to discover the full potential of your new FM transmitter. In some cases you could buy a model with a comfortable hands-free system, to answer and make phone calls while you are driving, always respecting safety and the highway code!
We have already mentioned the supply of these available, but it is always good to repeat it. Check that your model is compatible with USB connection to a portable device, such as your smartphone.
