Nulaxy KM30 Bluetooth Car Adapter, FM Transmitter with 1.8" Color Screen, Hands-Free Calling Strong Mic, QC3.0 Fast Charging, Treble & Bass Sound Music Player, Wireless Radio Receiver, AUX TF USB

I recently gifted my husband the NULAXY Bluetooth FM Transmitter, and it has been a fantastic addition to his car! The setup was incredibly easy; he just plugged it into the car's cigarette lighter, and it connected effortlessly to his smartphone via Bluetooth. One of the standout features is the crystal-clear sound quality. Whether he’s listening to his favorite music or taking calls, the audio comes through without any distortion. The built-in microphone picks up his voice clearly, making hands-free calling a breeze. The LCD display is a nice touch, showing the frequency and battery status, and the USB ports provide convenient charging options for his devices. He loves being able to stream his playlists and podcasts directly through the car's stereo system. Overall, the NULAXY Bluetooth FM Transmitter has made his driving experience more enjoyable and connected. It’s user-friendly, reliable, and an excellent value for the price. Highly recommended for anyone looking to upgrade their car audio setup!

Great little Bluetooth thingy! I'm an old broad, so I was a bit hesitant to install it on my own, but I went ahead. It took about one minute to get it up and running. It sounds good, phone calls sound good on both ends. I wish I had known about this little tech thingy sooner!

I've been using the KM30 in my 2003 Nissan pickup for the past three years, and it has exceeded my expectations. I don't listen to AM/FM radio. Instead, I stream music from YouTube over Bluetooth, and the KM30 has worked flawlessly. Bluetooth connectivity has been reliable, and the audio quality has been excellent. The hands-free calling feature also works great. Whenever I answer a call, the people on the other end can hear me clearly without any issues. I've seen some reviews mentioning alternator whine or electrical interference, but I've never experienced those problems. Very occasionally, if I'm driving through an area with a strong radio station, I might hear a little station bleed-through. However, by choosing one of the more obscure FM frequencies, it's rarely an issue. After nearly three years of daily use, this unit is still performing just as well as it did when I first installed it. Because of its reliability, sound quality, and call performance, I'm upgrading my original 4-star rating to a well-deserved 5 stars.

This transmitter not only sounds great, but it also looks and feels great. The sound quality is as good as your speakers allow it to be. In my case, everything sounds great. I rarely adjust the bass or treble unless I want to mess around with the audio, but it's not necessary. Make sure to use radio-locator or any other website for locating unused radio channels in order to get the best possible performance out of this product's main transmitter feature. The design allows it to be so low profile that it's not an eyesore. Make sure to remove it once you're done though because it does stay on and can slowly drain your car's battery. Another great thing about this product is its durability. I live in California so the sun is not shy to come out. I've left the product in our SUV's front compartment ever since I bought it, which was months ago, and it's still running perfectly. It remembers that it was connected to my phone so I simply plug it in, press play, and head on out. On that note, I would also like to mention that the media controls on this product work for all of the apps I use, such as Spotify, YouTube Music, and Youtube, even when the phone is off. I know that's a common feature, but many products get media controls wrong, not this one. Other things to mention are that the USB ports allow for exceptional charging performance, but I rarely use them so it's not so big a deal to me, but maybe for others. Also, the mic quality as described by people I've called through this product is not the best, but it's good enough to make out what you're saying. It's not a big issue to me because I do not call often when I'm driving, but many others do. The display is great at what it's supposed to do, such as displaying the song name, the song length, the song frequencies, radio station, etc. It's enough information that can be absorbed with a quick glance, do not look at it too long while driving. I cannot comment on the sd card and aux out functionality as I have not used them nor am I planning to because I have no need for them as of now. Overall, this transmitter has great sound quality, great build quality, great features, and a great value. I highly recommend this to anyone looking to add Bluetooth functionality to their car.

I bought the KM18 two years ago. This unit followed me wherever I went as a motorcoach operator. It always synced. It always greeted me with my most respected actor's voice or someone who sounded like him, James Earl Jones. I used it in my 2014 Jetta. I used it in the buses and vans I operated. Then I bought a 2008 Acura MDX. I had no problem with the fact that the Bluetooth system in the 2008 model was limited to making and receiving calls. I had my KM18. Unfortunately, the flexible neck design was a problem. It was just tall enough to almost always get jarred when I would move the gear selector or would try to operate any of the car controls nearby. The combination of the long and durable neck and the weight of the KM18 control unit would at least momentarily disconnect it. It would normally reconnect, but not always. I ordered the KM30, because it had more bells and whistles than other Nulaxy and other brands' models. I was of course pretty much set on Nulaxy because of the KM18, which my Bride and my son use in the 2014 Jetta (our back-up car). I love the display. I love that it displays whatever information is on my phone as to the programming. I love the ability to fine-tune the sound with the tone controls and the bass-boost function. It stays put in the power socket. It does not get in the way of the gear selector. It fits perfectly in the way that part of the center console is designed. It does sync better and faster with my phone. While I liked hearing the James Earl Jones or very good facsimile voice, I like the two beeps that tell me my phone is connected and ready. It seems to handle calls better than the KM18. I don't have to do anything but press the icon on my phone to answer. My voice is apparently clear to the other party. I have received no complaints about the clarity and quality of my sound. For fellow ham licensees I have a 357 hst. I can better control what is playing with the controls on the KM30. None of this is to denigrate the KM18. Clearly the KM30 is an upgrade. I highly recommend Nulaxy products, the KM18 and the KM30. I am most satisfied with the KM30.

This is really a no frills FM-Bluetooth Transmitter. But there are some faults to this. Let me share the bad then move on to the good. But let me share this major tip. Set the transmitter volume to maximum. While this is a FM-Bluetooth transmitter, it is really is not meant for phone to phone conversation & this product isn't it's strongest feature. Why? Let me explain. When making or receiving a call. You have to press your preset radio station if it's not already chosen to make or receive calls. Especially if you are listening to another preset radio station. It can be annoying to hit that FM Transmitter station. This has happened to me on several occasions. But it'll be repetitive soon. Now several users has mentioned about the feedback noise. While this is true and it stems from the alternator. It's only when you are on a bluetooth call and the radio volume is on a very high setting. However, this does not affect during bluetooth music streaming or using the USB Drive. What I mean is that, when you need to hear someone from the other end of a phone call. The transmitter isn't as strong to produce the sound to all speakers. Even when you have your phone bluetooth volume on maximum. YOu need to turn up the volume from your radio head unit. But again this also depends on your own car speakers as well. So that is one feature that could be improved if the manufacture decides to do so. My other annoyance, is the USB connection. Depending on the cable or USB drive you use. It can be somewhat a tight fit as you can see in my pic. Sure I can buy a right angle cord to charge my phone. But why add more cables to my collection? Now for the USB drive. This can be somewhat a good thing and a bad thing. Upon start up. It can either be recognized or not. Sometimes while playing it'll just go to "unrecognized" for several seconds. Then it comes back again. This product only plays MP3's. No wav, mp4. I cannot comment on AAC or ALAC as I don't have songs in those format. So if you going to bring your music onto a USB Drive. Be sure it's in a format that the KM 30 can play. I haven't tried the SD card feature as of yet. So I will make an update at a later time. The good. The Bluetooth streaming is great. Providing you set your equalizer on your phone correctly or neutral. Most modern Smartphones has an EQ feature. So I suggest you play your favorite song or a song that has a balance of bass, treble and mids. This will ensure that whatever streaming music you use. You will get that sound great. Even with the OEM speakers. Once that is complete. You will want to adjust your stock your radio sound settings. Most stock radio has bass, mids and treble. Set those at neutral and adjust accordingly. Then move onto the KM30 bass and treble and adjust accordingly. This will take some to get the sound you are after from your . Using a USB Drive? Well this all depends on your music library. If you have a library of music on a hard drive, not all music are set a particular bit rate (kbps). I know I don't. I have bit rates ranging from 92kbps to 320kbps. So the best method from my 2 week experience. Again find a music that is really balanced with bass, mids and treble and have a 128kbps. I actually used Metallica- Hollier than Thou and Delinquent Habits - California. Yes I have a wide range of music taste when I cruise. When you play you will have to make adjustments to the bass, mids and treble from your stock radio and from the KM30. So music lovers between normal radio stations, music streaming to music on a USB drive. You will need to find that balance of sound. While this might be a pain. It's so much better than making a phone call. Again this is a no frills FM-Bluetooth Transmitter. This works perfect for older cars once the sound is dialed in correctly. My only suggestion that this product would have an edge over the others. If this could pivot left and right. But that is a small pet peeve on my part. Enjoy! Car 2004 Mazda3 Hatchback. Stock Radio with 2 year old JBL Club 6x8 Speakers in 4 doors. No amps.

I gave 3 stars because it did work quite well at first, it just didn't keep working long enough to warrant a better review. Signal quality was good, but I only used it through the Aux plug in my car. The functionality is alright. Not much to complain about there. However, I got less than 2 months of use out of this before it just stopped working completely. So, I would say that it doesn't have the value for the money I spent that I was expecting. It was easy to use and set-up initially. Music playback was also good, so no complaints there. The issue is that this is obviously not built to last. Tbh, after the first month, I stopped using it for calls because it wasn't picking up my voice well and I couldn't really hear the other person very well, but it was fine with music, maps or podcasts. Until it just straight up stopped transmitting any sound at all yesterday. I tried everything and it just won't work now, so I'm having to find something else. I wouldn't recommend this to anyone who needs something reliable.

It was very simple to set up the quality of sound is great my old one had static and this one has zero static you can see the screen clear tells you what song is playing you can charge your phone it's a really great device

Há muitos anos que utilizo transmissores FM no carro para ouvir música, mas este equipamento superou todas as minhas expetativas! Excelente qualidade de som, com possibilidade de regular graves e agudos o que é pouco habitual, e contrariamente a outros equipamentos que já usei, não tem ruídos de fundo e a separação stereo é ótima! Felizmente temos em Portugal duas frequências que não são utilizadas por estações de rádio (87.5 e 108.0) e por isso, sintonizando numa destas frequências, podemos viajar todo o país sem necessidade de mudar de canal devido a interferências. As chamadas telefónicas são perfeitas e não tenho tido reclamações! Equipamento muito fácil de utilizar e o manual tira as dúvidas que possamos ter. Impossível ter melhor relação qualidade/preço. Recomendo!

Funktioniert sehr gut, einfache Installation, guter Klang,

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.

Le rendu est bon, l'installation facile et le prix très correct. Juste, pour moi, un très léger bémol, il n'y a pas de commande marche-arrêt. On le branche et il fonctionne. N'en ayant pas forcément besoin tout le temps, je suis obligé de le retirer et le remettre selon le cas. Est-ce qu'à force cela ne dégradera pas la prise allume cigare ? Je ne sais pas. Peut être oui peut être non

Arrivato ieri. Costato nulla. Inserito nella presa accendisigari, senza fare nulla, dopo 20 secondi si connette a frequenza radio libera, attivi il bluetooth sul telefono e due secondi il gioco e' fatto. Musica perfetta da smartphone, youtube, spotify,etc,etc. Si puo' ricaricare cellulare e ho provato una telefonata e tolto un leggere fruscio di sottofondo, ma ci puo' stare tranquillamente visto che funziona attarverso frequenza radio, perfetta anche quella. MI avevano chiesto 300, 400 euro per cambiare totalmente dispositivo audio , per poter telefonare e ascoltare musica....Ho trovato questo piccolo gioiello e per ora dico solo una cosa: geni a coloro che lo hanno inventato. Bravissimi.
