VicTsing Bluetooth FM Transmitter

VicTsing Bluetooth FM Transmitter

The VicTsing Bluetooth FM Transmitter is one of the most versatile transmitters out there. Without any efforts in designing it different from a few others, it still comes very great and easy to navigate.

To enhance the design is a broad LCD that displays the FM frequency you are tuned to, the name of song you are listening to, name of the person calling you, and the voltage of your car battery among other things.

Better than the design is the functionality of the transmitter. It has a voice prompt that lets you know when you are connected, and a microphone that allows you pick calls. With receiving and making calls, the microphone is very good even though it sometimes sounds somewhat muffled.

Looking at the music and FM sound quality, the VicTsing Bluetooth device gives a clear and warm reproduction, but it is not the loudest.

It has an auxiliary port and a port for TF card so that you get to play music from your TF card.

At the end of the day, with all that it offers, the device is still very easy to use and one with wide compatibility to include devices such as iPhone, Tablets, Samsung, Blackberry, Sony, and many other Bluetooth enabled devices.

Pros

  • Good LCD screen
  • Easy to use.
  • Good voice prompt.
  • Wide compatibility.

  • Not the best microphone
  • Not very loud.

Verdict

It doesn’t matter whether you are new to FM transmitters or not, this is a highly needed piece in your car. This is because of the many functions it comes with as well as the convenience of use and simplicity.

Nulaxy Wireless In-Car Bluetooth FM Transmitter

Nulaxy Wireless In-Car Bluetooth FM Transmitter

The Nulaxy Wireless In-Car Bluetooth transmitter is a futuristic looking piece that comes as big as it performs. The transmitter has a large LCD display that delivers different information including the number of anyone calling you if you connect it to your phone.

The design of the piece is easily great and the controls are placed conveniently.

Through the microphone it comes with, you will get to receive calls when you have your phone connected, and be able to stream live to the caller, even though it will not give you the clearest of calls possible. That is due to the distance and the fact that it picks background noise also.

To its connectivity, it is very easy to connect to your phone, and you can use either the Bluetooth, its two USB ports, or a 3.5mm audio jack. In essence, what this does is to ensure that you are able to have music played from almost any device.

I find myself loving this transmitter because of the range of features it comes with. These include a micoSD port that can read up to 32 GB card. Whether your songs are in MP3 or WMA formats, the Nulaxy Wireless In-Car Bluetooth transmitter will be able to play it without any problem.

Another great thing is with the sound quality you get with the transmitter. It is crystal clean and generously loud.

Pros

  • It has a very wide compatibility
  • Two USB ports
  • Generous features.
  • Hands-free talking support
  • Good audio performance.

Cons

  • It’s on the bigger side of transmitters.

Verdict

If you can bear the size, there are a lot of other things to beat with this transmitter. Most importantly, it comes with a broad compatibility and excellent functionality.

GOgroove FlexSMART X2 FM Transmitter

GOgroove FlexSMART X2

The GOgroove FlexSMART X2 is an easy to use transmitter that is great but not necessarily for someone looking to get bigger than life features.

A hands-free calling and FM transmitter, the piece comes with a USB and Bluetooth connection which allows for music to be played from your phone or allows you to get FM, just as it allows you pick your calls.

Because of how easy it is designed, the transmitter has straight to the point controls. The LCD is not as wide as you get with the VicTsing or Nulaxy, so it doesn’t give as much information as the two do. You also get powered USB if you need to have your phone charged.

The transmitter supports MP3 music formats and even though the audio sound is very crisp and clear, it is also loud. Just try not to get it too loud as you may get some distortion on the music when it’s all too loud.

At the end of the day, while most things seem to be great with the transmitter, it can sometimes get picky with the cars it works on.

Pros

  • The sound quality and strength of the Audio is very good.
  • It is flexible.
  • Setting and use is very easy.

Cons

  • It is not the cheapest.
  • It neither gives caller ID nor voice commands.

Verdict

The transmitter has both beauty and simplicity. It doesn’t offer as much as many others on the list but if you are looking for one that is easy to control, flexibility, and durability, this may just be your pick.

Aphaca Wireless Bluetooth FM Transmitter

Best FM transmitter

Aphaca Wireless Bluetooth FM Transmitter

One thing that is quite surprising is how the Aphaca Wireless Bluetooth FM Transmitter still manages to be a rather less known FM transmitter with the bulk of things it has to offer, and with its unique design.

The transmitter has a solid 4.2 Bluetooth which easily connects to your iPhone, Android, or any other Bluetooth enabled device.

A warm and crystal sound reproduction is what the transmitter has to offer, and it comes also as a hands-free device which means that you get to pick calls coming through your Bluetooth connected phone.

There is one problem with most other hands-free transmitters when you are answering calls and that is the noise the pick. To take care of this problem, it comes with the CVC technology which gives you noise cancellation and better general sound quality.

Car locator is another technology that is fashioned on the transmitter. This is possible thanks to the Fast Find Car App of the transmitter that works by saving the location of the car on the app immediately it is parked. It also adds the distance and directions to the place of parking on the app.

Finally, it has two USB ports for phone charging and to read U disk and USB flash drive. It also has a port for Micro SD cards of up to 32GB and it plays MP3 files.

Pros

  • Unique design
  • Powerful and great sound.
  • Amazing car locator.
  • It has good compatibility.

Cons

  • It is not the easiest to use, so you may need some time to firmly understand it.

Verdict

If you are looking for the one that acts great, but doesn’t have the looks of the regular, this is a good bargain. To top everything, you get good sound and microphone, as well as the safety of your car with the car locator.

Motorola Roadster 2 FM Transmitter

Motorola Roadster 2

Different from all others and definitely in a class of its own is the Motorola Roadster 2. It is not one of those that you can easily call a regular transmitter, as I will recommend it better for someone more interested in answering clean calls when driving than anything else.

Not to get it wrong, it still serves very much in FM transmission and giving you the option of music listening through its Bluetooth when you connect to your phone. With the FM performance, there is hardly a thing that separates what it gives from most others on the list.

You can use it to transmit songs from your smartphone to via the transmitter to your car radio and it will use the car speakers to play. Playing directly from the speaker of the transmitter is also great as it is both clear and loud, even though you will get some very little distortion when at the loudest.

One more thing that is exceptional about it is the GPS feature, which helps you find your car when you can’t remember where you parked it. That is through the Motorola Car Finder app that is available for Android.

Lastly, the design is simple and yet amazing. It doesn’t come with an LCD, just the speaker, and the buttons. Yes, the design is very solid also.

Pros

  • Comes with good features.
  • Clear phone calls
  • The audio quality is very great
  • It is a solid device.

Cons

  • It has no LCD.
  • The controls are not the best placed.

Verdict

The Motorola Roadster 2 is very different from many others. Although it comes with good overall functionality, it is for someone looking for better calls when driving. If you have a huge appetite, I will recommend something else on the list.
