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

The media could not be loaded. 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!Car2004 Mazda3 Hatchback.Stock Radio with 2 year old JBL Club 6x8 Speakers in 4 doors. No amps.

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.

Likes: Works as adverstised. I would find an unused FM channel and connect to my car's FM/AM radio. I'd connect my iPhone via USB-A cable to this transmitter and am also able to charge my phone. Once I fiddled with 3 volume settings (phone, transmitter, radio), I was able to listen to decent quality music and audio on phone calls. Tuning was easy. Size was about right.Dislikes: Signal interference near clusters of tall building or near transmission towers. Low volume unless I play around with the three volume settings (see above). If you do this approach, please remember to turn down your radio volume when disconnecting the transmitter or you'll get a nasty loud audio blast.

Works perfectly. There's almost no radio hum/fuzz. If you have your stereo super loud in between songs you might hear a little bit but it does a really good job. You could even put it on a station that the radio would normally pick up and it pretty much overrides it. My only critique with this would be the screen is not near as nice as they depict in the picture. I'm an audio engineer and while the bands do somewhat go with the audio, they definitely don't react to any specific frequency. But definitely worth the money for those of us with older cars and head units that don't have Bluetooth. I'm also able to plug my dash cam into one of the USB ports on the side.
