7 RGB Color Backlit QC 3.0 FM Transmitter

I'm currently using this one on a E46 2001 while I switch to a touch screen radio, nevertheless this gadget works miracles. It gives the voltage of your battery/alternator which has been a life saver, great voice activate recognition, great for WA message recordings, phone calls, listening to music, cool lights, fast charging for iPhone -- I mean, what else could you ask for?

As other reviewers had stated, there IS a static sound, but I like my music loud, it drowns out the static sound completely, meaning i never hear it

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  - NX09 BCADON Bluetooth 5.3 FM Transmitter for car  - BC89 IMDEN Bluetooth 5.0 FM Transmitter for Car  - C57 Octeso Upgraded V5.0 FM Bluetooth Transmitter Car  - BH347 Upgraded Criacr V5.0 Bluetooth FM Transmitter for Car  - Carkit FM Transmitter for Car Bluetooth 5.3, RIWUSI (All-Metal)  - BC61 Octeso New Bluetooth Car Adapter - 48W PD&QC3.0 Bluetooth FM Transmitter  - BH549 FM 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.

I have had this Bluetooth transmitter in my car for 5 months now and I have never had a problem with it. It is a great and cheap way to listen to Spotify on those longer drives, or anytime you get in the car.

I have bought several of these for myself and family. They are easy to set your station and to use.

Seems to work well, but I couldn't figure out how to change the station. The "instructions" say to short press the << or >> buttons. Actually you have to long press the button until the display starts flashing, then you can change the station by short pressing the buttons. This may be nice to have in the instructions, however the print on them is so small you may need to have a Pekingese dog that you have trained to read.Otherwise, this appears to work well. All I really want is to be able to listen to files on my phone in my very very pre bluetooth truck radio- oh yeah, and I like to keep my hard earned money so the price is on point.

The AUX port on my factory head unit no longer works correctly, so I had to get creative to stream music through my car stereo. The previous device I was using converted Bluetooth to stereo mini plug, which used the AUX port; it would power down with the car as it was USB powered from the console USB port that was ignition switched. Unfortunately, this device uses a 12V cigarette lighter port as it's power supply, and those are not switched. Now, when I shut down my car, I have to remember to unplug this device or my phone stays connected and my music will continue to stream. I have not found a power switch on this device, and I'm not entirely happy with replugging it every time I drive. Also, it appears to not broadcast in stereo, which makes the music sound bland.

So my Bluetooth in my car was acting crazy! So I order this device and it’s saved my life hahaI really hate listening to the radio! The sound was great! That was one thing I was worried about! Works great! Very easy to use n set up! Buy NOW!

Sound quality was surprisingly good.

Item is excellent quality, connects to phone Bluetooth very easily. Sound quality is very good.

It’s east to use and it’s never given me issues with connectivity in places with bad reception but you can’t turn the volume up that high without having a weird cracking noise

fantastic unit so easy to use

I bought this for my first car and it's amazing. I thought I would of had to buy a whole new radio to play my own music but my Friend told me to buy one of these so I did and it's great. I put it in Connected my phone to it and it worked immediately. 10/10
