IMDEN Bluetooth 6.0 FM Transmitter for Car Adapter with MP3 Player

3 time i’ve bought this for a different vehicle over the years. it has been the best transmitter i’ve ever owned, zero issues in connecting easy to use. gives out a very clean signal and loud. will always buy if i need to get another for a different car.

This little contraption works like a dang charm! Plugged it into my truck and it picked up Bluetooth quicker than this rancher spots an open pasture. Sound comes through nice and clear, and it’s simple as heck to use. For the price, this here gadget is worth every penny. Five stars from this ol’ rancher!

Like many others shopping for a Bluetooth adapter for their car, there appear to be too many choices. After trying a bunch of them out, here are some thoughts. Listed in no particular order, only how they appear in photos from left to right, top to bottom.Nulaxy Bluetooth FM Transmitter - NX09BCADON Bluetooth 5.3 FM Transmitter for car - BC89IMDEN Bluetooth 5.0 FM Transmitter for Car - C57Octeso Upgraded V5.0 FM Bluetooth Transmitter Car - BH347Upgraded Criacr V5.0 Bluetooth FM Transmitter for Car - CarkitFM Transmitter for Car Bluetooth 5.3, RIWUSI (All-Metal) - BC61Octeso New Bluetooth Car Adapter - 48W PD&QC3.0 Bluetooth FM Transmitter - BH549FM JOYROOM Bluetooth 5.3 FM Transmitter Car Adapter, - JJ-CCB01Bluetooth pairing name: “NX09”FM Range: 88.1-107.9LED selection: RGB, yellow/green, purple, teal, white, noneWhen this starts up, you see voltage for a brief window the voice notification is “at normal voltage, Bluetooth mode.” The female voice is really robotic, more so than any of the other adapters. At a passing glance, you could have sworn it said “abnormal voltage,” but looking at the manual that’s not even a possible option. Once connected it says “Bluetooth connection success.” There’s faint line noise at lvl 45 on my OEM Toyota stereo and the adapter set at level 30 (max). You need to long press the >> button until the station flashes and then you can use the << and >> buttons to change station value. If you have an overhanging/underhanging console, you can rotate the adapter so that all the buttons are accessible (microSD/LED selection on left, USB on top, controls on bottom) but since it’s only the right side wall is blank, everything is going to be 90 degrees offset.Bluetooth pairing name: “BC89”FM Range: 87.5-108.0LED selection: red, green, blue, yellow/brown, yellow/green, teal, purple, noneThis is one of two adapters that actually uses real metal (aluminum in the body, though in this case, it’s only the walls of the fat bulb sticking out of the socket. The body of the socket itself is transparent dark blue ABS plastic. Starting up, you see “HI” (no idea why they did this) then voltage for a brief moment, afterwards the female voice notification is “normal voltage, Bluetooth mode, wait for connection.” Then you get “Bluetooth connection success” after pairing. The voice for “normal voltage” enunciates “normal” more clearly than Nulaxy, and oddly “normal voltage” part of the voice is different than “Bluetooth mode, wait for connect.”There’s a small noticeable whine in the line noise at lvl 45 on my OEM Toyota stereo and the adapter set at level 31 (max). The controls are nice. The 4-way joystick like button make it easy to control. You need to long press down to change channel then toggle up and down on joystick to change value. The LED selection button sits on the top of the side wall, but since it’s the only control, it’s easy to rotate to be accessible if your console is in the way.Bluetooth pairing name: “C57”FM Range: 88.1-107.9LED selection: N/AIf you like no frills, this is probably the right adapter. No LED illumination ring at all. There is no notification on voltage. It is just displayed briefly and is only forefront if it’s under 12V, which is when it will blink as an alert. Otherwise, the male voice simply states “waiting for pairing” and then “paired.” The front display is not shiny. It’s just matte black and the LED is illuminated through it. There’s faint line noise at lvl 45 on my OEM Toyota stereo and the adapter set at level 30 (max). You need to long press on center button until the station value is flashing to change the station.Bluetooth pairing name: “BH347”FM Range: 87.5-108.0LED selection: N/AThe female voice on this sounds ok, nothing quirk, but still quite stiff. It goes “Bluetooth mode” then “Bluetooth connected.” There’s faint line noise at lvl 45 on my OEM Toyota stereo and the adapter set at level 30 (max). More so than the C57 and NX09, but less than the BC89. To change the channel, you need to short press the center button then you can use the << and >> to change value. With our overhanging console, we often find ourselves rotating the plug 90 degrees to keep all the buttons accessible.Bluetooth pairing name: “Carkit”FM Range: 88.1-107.9LED selection: red, green, blue, orange, lime, teal, purple, noneThis has a similar voice to the NX09 adapter, but more natural sounding – “normal voltage, wait for connection” and “bluetooth connection success.” It does the same “HI” thing as the BC89 and has the same voice sequence; along with the box design (and model name – BC41) makes me think they are out of the same factory. The “normal voltage” sequence of the voice sounds different here too, similar to BC89; there are two different voices. There’s some slight line noise at lvl 45 on my OEM Toyota stereo and the adapter set at level 30 (max). To change the channel, you need to short press the center button then you can use the << and >> to change value.Bluetooth pairing name: “BC61”FM Range: 87.5-108.0LED selection: N/A (just blue)The voice on this sounds similar to the Carkit and the BC89 (fairly natural) – “power on, Bluetooth waiting for connection” then “Bluetooth connected.” The enunciation in the voice sounds correct, but it’s like they spliced two different parts of a conversation together. The “power” part sounds like it was recorded/generated separately from “on” and there’s a slight “bluue toooth” sound that makes you think that you are listing to two separate words rather than one.It also does the same “HI” start message with battery voltage briefly displayed like the Carkit and BC89. There’s some slight line noise at lvl 45 on my OEM Toyota stereo and the adapter set at level 30 (max). The thing about this that is unique is the all aluminum body construction. You can feel it’s sturdiness. All the controls and ports are in the face, which makes it less cumbersome to fiddle with. Long press down on call button to change station. While it’s nice to have a PD port, it would have been even better to have two full sized USB ports, probably the only gripe.Bluetooth pairing name: “BH549”FM Range: 87.5-108.0LED selection: LED light, low, noneThe battery voltage is displayed briefly on startup, then the voice goes “power on, Bluetooth, waiting for connection” then “Bluetooth is connected.” It sounds awefully similar to the RIWUSI adapter. The “power” and “on” sound ok but there is a distinct “Bluuue tooooth” that follows. It’s much more pronounced and noticeable than the BC61 adapter. Oddly, the second “Bluetooth” in “Bluetooth is connected” sounds fine. There’s some slight line noise at lvl 45 on my OEM Toyota stereo and the adapter set at level 30 (max) that seems a bit more noticeable than other adapters save the whine on the BC89. The buttons on this are a bit frustrating since there’s no tactile feedback. To change the channel, you long press down on the center than use << and >> to tweak station value. However, think of a touchscreen without any vibrate or audio cue. The touch sensor exists but there are no physical buttons in that nothing depresses or moves. That makes you sometimes second guess if you actually touched the button successfully to register a hit. This adapter has a larger face, but even if your console overhangs a bit (like mind), it still small enough that nothing butts up against anything.Bluetooth pairing name: “JJ-CCB01”FM Range: 88.1-107.9LED selection: LED light, noneThe adapter has no voice notification. You see battery voltage briefly and hear a chime when starting up and when Bluetooth is connected. There’s little line noise at lvl 45 on my OEM Toyota stereo and the adapter set at level 30 (max). The controls on this are nice. It’s like a toggle knob. You long press down until channel flashes, then turn the knob left and right to change channel. The knobs only turn maximum about 30 degrees each way similar to car radios, so you kind of flick your way to channel you want to set. The problem for many will be that the dual mics are situated at the top, so if you have an overhanging console, not only does it make it a tight squeeze, but it also blocks a clear path to pickup audio.

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.

Before buying this, I compared to probably 10-15 other FM transmitters, googled reviews on external websites, etc. This one showed up most consistently in reviews as having the best sound and call quality, somehow.I received it in new condition, install was a no-brainer like every other FM transmitter: plug it into your power outlet and then pair with a device. It does pair immediately when you turn on your car and seems to have strong connectivity since over a few weeks of using it I've never had any issues with my phone staying connected.The sound quality when playing music is okay to decent. It largely depends on how clear of a radio station you can find, and if you don't have access to any unused channels then your mileage might vary in terms of clarity. In my area, I was only able to find a station that wasn't entirely clear but the transmitter overwrote the broadcast with a little fuzziness. It won't sound like a CD, auxiliary input, or USB input playing, so don't expect to get crystal clear sound quality with this (despite how exaggerated some of the other reviews are). It's still just an FM transmitter.The call quality is pretty abysmal to the point of being unusable. I actually made the choice to buy this on the pretense that it had very good call quality, being one of the stand-out points many reviewers made. In reality, the quality is not good. Hearing people is fine, which is expected, since the transmitter is literally just a stand-in for your phone's own sound. If you can hear people on your phone well, then you will hear people through your speakers well, too. The issue is that even when very close to the microphone on this unit, outgoing voice sound is very muffled and quiet for anyone calling you. I have used this unit's microphone for multiple types of calls, including calls through Discord and Skype and through normal cellphone service with full signal. Always the same results: incoming sound is fine as would be expecting since that depends on your phone, and outgoing sound is borderline inaudible through this unit's microphone. This happened with both my car in park idling and in motion, so the issue is not with having a loud engine or car noise. Whatever the noise-canceling function that's built into this does doesn't actually work.The unit also does not power off on its own. So, if you have a car with auxiliary power that stays hot for a while after you turn it off, it could be a liability for your battery. You'll have to unplug it and plug it back in every time if your car doesn't power off the outlet.Other things: the unit looks fine, it's very unobtrusive and small. It shouldn't clash with much in the exterior of any car, besides the old-school orange display on the top (you can't turn it off). Depending on where your power outlet in your car is, it may be difficult to use the buttons on the sides unless you rotate it. The "quick-charging" feature is just marketing buzzwords, like everything else that advertises it, this will charge your phone at the same speed as any other USB 3.0 outlet and will be compatible only if the device itself (not the FM transmitter) supports Quick Charging.Ultimately, this FM transmitter is only better than the competition if you prefer how it looks. They all do virtually the same things and do them in more or less the same way, with the same pros and cons. Some have extra features, others are more straightforward. This one is firmly average. It won't blow your mind with amazingly clear calls or sound, like some people have reviewed.

Wasn't sure what to expect but I liked the unobtrusiveness of this device and other reviews were good so I took a chance. I have a 1998 sports car with no native bluetooth or usb functions and this fit the bill perfectly. It was very simple to synch to a non-used FM frequency on my radio and began streaming audio from my iphone thru the car speakers immediately. Haven't had a chance to test the phone function yet but it streams and charges from the USB port quite well. Recommended purchase. This has all I need. If you desire more bells and whistles, it will be at the cost of compactness.

OMG this just saved me from replacing a really expensive stereo in my old Mercedes! It was easy and works perfect for playing my music off my phone.
