Nulaxy Car Bluetooth Transmitter, 1.8" Color Screen Bluetooth Car Radio Adapter with Strong Microphone for Better Hands Free Calls, Supports QC3.0 Charging, Treble and Bass Sound Music Player- KM30

Had a few of these type of devices over the years and they have all been a bit of a let down. Thought I would give this one a go due to the good reviews and wow, what a difference. I have been using it now for over a month and it has worked flawlessly the entire time. No issues with bt connection but the main positive for me is that I have had no problems with interference and the sound quality for streaming music has been excellent. Then you get the bonus of the nice screen with some info on what's playing and a equaliser. Hands free wise, it always works great and I can be heard clearly by callers. I really am very pleased with this device, worth every penny and saved me having to upgrade the head unit on my car.

I have owned these FM transmitters in the past and they've been pretty useless. However this one has been great. I've used it in 3 very different cars, no fitment issues. The voltage readout warns you of a bad battery, which is genuinely useful. Once set, it doesn't forget the FM frequency even if you don't use it for ages. I never have a problem connecting it to my phone. It just works. The display is good, it doesn't look tacky in a nice car. I have volume and base at permanent 100%. Audio quality is just fine, no 'hiss'. Not used the phone / mic. Not used the SD card. As a means to listen to Spotify in any car with a radio, it just does the job. A carry pouch would be useful (I use an old sunglasses bag) as you can't leave it permanently 'on show' in the car as some idiot will put the window through for it. You can buy these for much cheaper, but I'm glad I paid a bit more for this (£23). Good product.

Excellent, I'm happy with everything so far. Only had it for a few days now. Things to improve is to have more gap between the USB and charging slot because if the USB stick is not slim you'll struggle to get them in at the same time. Most important thing for me is that you can choose which folder to play. It would help if there was a button to forward the songs on the playlist. Performance wise I'm happy.

Oh my goodness - this little thing is great. My expectations for 20 odd quid were not high, but I needed something to play my MP3 collection through my car stereo (i have an older car with a tape player, a CD changer but no AUX input or Bluetooth. This worked out of the box with my 64 GB ExFAT USB stick (and I am able to browser folders / albums through its mini file browser) . Sound quality is fine - you'll want to tweak the Treble & Bass. I tuned it to an empty frequency at the lower end of the FM band (seems perfectly fine) - I can always easily retune it if I drive in London for example and get swamped by local stations etc. I have tested its mobile hands free Bluetooth mode - no problems - not top notch fidelity on voice, but absolutely fine. Value: five 5 stars Features: 5 stars Ease of use: 5 stars For £20'ish quid! It's bloody marvellous - music problems solved in my old Shogun.

I think I made the right purchase buying the Nulaxy car transmitter KM30. I bought it, because I couldn't find my KM20 which is buried somewhere amongst stuff from the kitchen. I had to disconnect my car's Bluetooth due to it draining my car's battery. I wanted to be able to listen to music whilst driving to Essex this weekend. There are so many transmitters to choose from. The old one was a KM20 with a long stork, it damaged my car's power socket because the fitting was too tight. The KM30 is a tight fit too, but I wanted to hear my music. It was simple to fit, pair up and operate. The sound quality is great, the bass is great, the treble is good. At first, I thought there was a tuning problem, because the frequency kept changing. It turned out to be the TA/PTY was on. I turned it off, the frequency locked in. Playing music, the volume seemed low. The bass wasn't booming, and the treble didn't seem refined. Everything sounded clear so I resigned to the idea that was all I would get. Until, on my return journey I turned the volume up and pressed the Bass button. I was presently surprised with sound I was hearing! Excellent sound quality. Excellent bass and treble. I could hear the instruments clear. I'm happy, because whilst driving my mum and sister to Essex, we can all listen to Mahalia Jackson (mum's favourite gospel singer) together! Have a happy day!

Used it in my camper van but it wasn't suitable for that purpose. Seems a decent quality.

Really pleased with this device, it was easy to install (install might be too grand a word for it as it really was so easy), works really well and was superb value for money. Linked to my phone really easily via Bluetooth and works well tuned into my car radio. I have subsequently plugged in the auxiliary cable as I have a substantial "radio deadspot" on my commute to work and using the aux cable negates this issue. No noticeable loss of sound quality via either method. Also works great for calls, the mic picks up well and the sound through the speakers is loud and clear. Works with the Google assistant for hands free making/answering calls using voice commands. Hard to believe it's as good as it is for the asking price but it really is. I also love the utterly pointless but delightfully retro graphic equaliser on the little screen as it plays 😁

In a previous review featuring an image, I saw the radio displayed "ST" during the demonstration, suggesting the presence of stereo broadcasting. I purchase this product with the hope that it would be one of the few units on the market capable of true stereo broadcasting, ensuring music sounds as if it is being played from a professional radio station. I have experimented with several models from various manufacturers, each claiming "Stereo" or "Hi-Fi" quality sound. However, in reality, none have met these claims. This product, however, stands out as an exception. It has exceeded my expectations with its genuine full stereo broadcasting capabilities and enhanced audio processing. This should be a major advertising point for the product. If I was to mark the device down at all, I would like there to be a button to turn off the screen and all LED lights as it is pretty bright when driving at night.

Es ist wirklich sehr gutes Produkt. Stereo , fast perfektes Ton mit starken Bass. Empfelenswert.

works like a charm easy to connect controls are awesome call quality is great music is wonderful

Muy recomendable. Estoy encantado con el producto. Facilisimo de instalar, muy intuitivo incluso para mí (62 años) aunque trae instrucciones en español. Sonido espectacular, envías música desde tu smartphone, puedes instalar tu pendrive con música, si quitas el pendrive el sistema recuerda donde lo habías dejado y continúa con la misma canción anterior, las llamadas se contestan con gran claridad, te escuchan perfectamente y sin interferencias, puedes cargar tu móvil. Ojalá todos los aparatos fuesen como éste, me encanta y lo recomiendo a todo el mundo.

So far so good! I was surprised at how small it is, but it works really well. I found that you do have to find the right “channel” to avoid static and/or interference, but once you do, it’s good, clear audio. I also got immediate connection to my 2004 F150 via the cigarette lighter. I’m so glad I’ll be able to listen to my own downloaded music even when driving through internet dead zones, and now I can really enjoy my drives to my favourite summer campsites without having to bring CDs! I haven’t tried the phone call option yet, but I’m optimistic about it working just fine. I’m very happy with my purchase.
