- Reviewed in the United States on January 14, 2023Currently I've got an old truck with no aux and the cd player is busted, I resort to fm transmitters out of necessity. I have tried several FM transmitters over the years on this vehicle and previous ones. Recently I lost my old transmitter and tried a few new ones and tried several Roav models that stunk either on clarity or volume. I got this one because I figured at the very least the unit being on a cord I could place it on my dash marginally closer to the antenna. Well it turned out to not matter. The sound quality on the fm transmitter of this one is impressively good.
Compared to the other ones I have tried this one sounds really good for what it is. It blocks out static/interference, comes through clear, can turn it up quite loud, and it actual has (relatively) good preservation of the audio quality. I can definitely hear parts of the songs that were lost with my previous fm tuner.
The bass boost works with mixed results depending on the song. If it had a few levels of adjustment maybe that would be even better, but that's jsut being picky at this point.
I am super happy with this unit so far. I don't use it for any of the hands-free calling stuff so far, but for listening to music with the FM transmitter part I am very, very pleased. I knew good ones existed because I've had them drive by me on the road and dominate my radio for a few seconds, but I've tried so many and have had to settle for mediocre at best. The fm transmitter on this one is downright decent, If you have tried others and settled for something half good maybe consider trying this one.
- Reviewed in the United States on June 15, 2022I didn't have very high expectations as I have tried several of these contraptions. :) This one blew me away the second I turned a song on, then I hit the Bass button....and Holy crap batman!!! Nice job....totally worth it, I am so glad I got this one.
Edited - The clip is a bitch, it won't stay attached to the vent clips. But still the sound is great, I'll figure something out.
02/23 EDITED AGAIN - After owing this product for a while now, I finally tried the sd card slot to see if it would be easier than connecting my phone when I want to use it. The slot did nothing. I contacted Nulaxy a few times to ask if I am doing something wrong and I have not heard back from Nulaxy as of yet. Email is only way to contact them. No phone number on site. Supposedly offer chat but have never seen it available. SO.......putting it down to 3 stars though the bass is still amazing the customer service has been crap.
After screwing around with the sd card I got it to work, but I have to eject and reinsert every time I start my truck.
- Reviewed in the United States on August 29, 2022Great plan B for the LX470 that doesn't have blue tooth. Pretty easy setup. Select a clear FM station on the cars stereo, program the device to that station, connect the phone via BT and wa-la, instant hands free BT.!
The sound is clear over the speakers and the mic apparently provides good pickup of voices. The clamps are holding the device securely to the air fins. I bought it with the cord from the charge plug to bring the device higher up in the car. That way I wouldn't have to look down to view the screen. Great product.
- Reviewed in the United States on June 30, 2024Trouble free and works well, over 6months now. Had others, this works
- Reviewed in the United States on August 18, 2023The receiver has been perfect except the know turns up the sound and it doesn’t let me tune the station. When I travel longer distances I have to deal with other radio stations and I can’t choose a different frequency to use. Looking for someone how who still has there manual who can give me the answer to this issue.
- Reviewed in the United States on May 3, 2022I have an old truck, and I wanted a way to play my itouch through the radio. I read the reviews about the Nulaxy BT transmitter, thought I'd try it and it worked great. My only small complaint is the Manuel does not go into a lot of detail, but though using the device I figured it out. Sound is great, and using an sd card that I put some music on, was great. I wish the designers would have put indents on the sd card slot as I had to remove the transmitter from my truck so I could remove the sd card from the sd slot. Over all I am well pleased.
- Reviewed in the United States on January 22, 2023Could be louder. Bass boost is overwhelming. What I like is it seems to learn usage
- Reviewed in the United States on June 18, 2023This was recommend to my to use Bluetooth from my iPhone and be able to make hands free phone calls while traveling. So glad to have this. I use it everyday. I listen to audio books and YouTube videos. The bass sound feature is a very nice addition to listen to good music.

5.0 out of 5 stars The best FM transmitter I've bought
I bought this for my son to use in our 2005 SUV. This thing is crystal clear when I'm talking to him. The noise cancellation is incredible. Absolutely no background noise. I've used it myself in the vehicle and it transmits perfectly and clearly to the radio. Extremely simple to use.
Remember folks, it's an FM transmitter! If you have interference, change the frequency it is transmitting on to a different frequency.
The vent clip has a dial nut on it to tighten the clip to the vent louvers. Placement of these transmitters is crucial. This one is designed to be at the dash vent level so that it can pick up your voice clearly, hence why it has a corded cigarette lighter adapter.
I like it so much I've bought a second one!

5.0 out of 5 stars Amazing works as said
I have a 2006 Pontiac vibe that doesn’t have Bluetooth or aux so this was a must have if I wanted to listen to music. I had to upgrade from an old one from a couple years ago and this one works way better. I like that it has a separate volume setting, skip setting and pause/answer calls button right by the steering wheel for easy access. Also another thing, THE BASE !!! Love it it’s the best, you can rlly feel the music that way
Overall def recommend!! Thank u seller!

4.0 out of 5 stars Clamp problem.
This has got to be the worst clamp assembly possible. It’s not designed to squeeze down other than in a V position.
So in brief it would not hold onto the grill for the ventilation I had to make a clamp to slip in to my dashboard for to hold onto.
Instructions are not idiot proof but I finally figured it out.
When’s connected it sounds fine it was just a question of funny the rates radio station to avoid static.

5.0 out of 5 stars Crystal clear audio from streaming via Bluetooth for music and phone calls
Works great, got this to replace another Nulaxy transmitter I've had for years. Very easy to setup, not sure why many people complain about the instructions. Just plug it in and hold the "call" button on the device for 3 seconds to tune the signal and you're done.

3.0 out of 5 stars Annoying to use
Can't disable Bluetooth (I use aux) and it keeps flashing until you connect. Button functions aren't very obvious. It does the job, but not user friendly.
