IMDEN Bluetooth 5.4 FM Transmitter for Car, MP3 Music Player Wireless Radio Adapter Kit with QC 3.0 Fast Charger, Hands-Free Calling, Supports USB Drive for 12V/24V Vehicles

This Bluetooth 5.3 FM transmitter turned out to be a solid little gadget for the car. Setup was quick — just plug it in, match the station, and it connected to my phone right away. The sound is clear with no static, and it handles calls and music without cutting out. I like the USB ports for fast charging and the bright display that’s easy to see, even during the day. It’s a simple way to bring Bluetooth and hands-free features to an older vehicle. I use mine on long drives, and it’s been rock steady the whole time.

TL;DR - Works great, strong FM signal, solid Bluetooth connectivity, fast charging via indicated USB type-A port. Low volume. Background: Like many folks, I still have a car with a stone-age factory radio, devoid of Bluetooth. With the local radio stations either having weak signals or playing ads and talk segments more than music (exaggerated, even only if barely), I knew I had to find a solution to pair my phone to my car's stereo so I could listen to what I wanted. Naturally, the thought to replace the factory head unit with something more modern crossed my mind. However, I'd decided against it, because it later occurred to me that I may be switching cars within a year's time. Seemed like the ideal circumstance for something simple and inexpensive to tide me over until then. Enter: this FM transmitter with Bluetooth! The Good: I purchased this device during a Lightning Deal, making its price point even more attractive. Having used devices like this before, I truly appreciated its compact design and dual charge ports (one of which delivers fast charging). Being that it was so inexpensive, I wasn't expecting a lot when I first received it. That said, I was rather impressed with how strong the built-in FM transmitter was! I tuned my radio to a frequency without reception, set that frequency on the device, and there was utter silence from the radio (i.e. no sounds of neighbor stations competing with the device). Once I paired the Bluetooth to my phone, I was able to play music with issue. Furthermore, I've had no problems whatsoever with the Bluetooth connection being unstable, songs breaking up/skipping, or disconnection. The Bad: Nothing's perfect, right? The only real gripe I have with this transmitter (which I've encountered in every FM-to-Bluetooth device I've ever used) is that the volume seems roughly 60-65% of that which is natively produced by the car stereo (AM/FM/XM, CD, etc). Even with the Bluetooth volume maxed out on my phone, I have to turn the stereo volume up to 30% before I can hear anything, 50% to hear it well, and 75-80% or more if I'm driving along at highway speeds. The only reason why I won't take a star away in my review is because this issue appears to be common to this type of device (perhaps due to some scientific limitations which I don't understand), so I can't fault it or the manufacturer for it. Conclusion: If your use case is similar to mine, where you simply want to have your phone's audio playing through your car's stereo with minimal fuss and associated cost, I can't begin to see how you could go wrong with this product.

This FM transmitter is great in all the important ways -- it works, it sounds decent... However, it's MONO. That means if a song has sounds in the left and sounds in the right, you're going to hear them both centered. This is disappointing, but MOST fm transmitters are mono, apparently. It's difficult to find one that isn't. Also, it's a little quiet... Meaning if you crank the volume on your phone it's fine -- but when you switch back to your car's radio, the car's radio will be a lot louder. So don't be startled. The Bluetooth connectivity is REALLY good. That was my biggest concern. It JUST WORKS. You come to the car, it recognizes your phone, and pairs... Even if your phone was just using your headphones before. It all just works seamlessly... And if you need to reconnect it's fine. The only concern is if you have two cars with two of these... They have the same name in the Bluetooth list so it's impossible to know which one you're connecting to! Overall this thing is really good for most people. The mono is disappointing, but the rest works well enough that I give it a solid 4 stars. For comparison, I used one from Wal-Mart before that was straight up unusable for a variety of reasons. This one is pretty great... As long as you're OK with mono!

I have had this transmitter in my car for over 6 years now and it still works just fine. The clarity is great and connecting to multiple phones is simple. I won’t be surprised if it outlives my car.

So far been using this product and it is very good. It has a very smooth sound and is easy to use, I would recommend if you have a Honda 2004 like me 👍 no regrets.
