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.

I've used this daily for nearly a year now. I play MP3s on a Micro SD Card sending it thru the FM radio.That aspect works rather well and I can change my Playlist at will.I do have two glitches to report tho,1) the unit swivels on the power plug and on occasion I have a power connection problem. I have to jiggle or swivel the unit to get it to power up.2) too often a song will Freeze in the middle of play. Pressing buttons has no effect. I have to unplug the unit, reinstall the SD card and plug it back in. This will fix it until it happens again.

This thing is great! First the look. It has the appearance of an mp3. Function. It connects well every time, and the sound works great with my vehicle. It displays the name of the artist and tune even when connected to my Bluetooth. Minor cons are sometimes it takes a few seconds to play the music when pressing the volume button. Like if I turned off the car, went into the store and come back. And sometimes it fails to skip to the next song. But it's no big deal. It's pretty decent.

If you drive older vehicles as I do this fm transmitter is one of the best sounding ones I’ve ever owned.(I’ve bought almost ever one in person I can find. Might not be good in an application where your cigarette lighter port is in a small area. (like near your shifter in a manual or in a cubby)The treble and bass adjust is a nice little feature on it.

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.

Previously owned the older version of this, the KM20. Campared to the KM20, this has a brighter screen and maybe better audio, but all the other changes have made this worse:-Old version defaulted to the SD Card for music, now you have to access a clunky menu to switch to USB-Press and hold knob to access the menu, but press too fast and it calls the last number you dialed.-Next track button is buried behind the knob (my most used button)-USB Audio gets glitchy and starts playing garbled nonsense- sometimes it will eventually skip the song or continue but its 10-20 seconds of glitchy or no audio.-Why is Channel + to the LEFT of Channel -EDIT----Nuvaly reached out to me based on the review and made things right - I will definitely look forward to the next version of this product!

Item was very static and would not stay in tune with my radio station

Fast shipping, Quality Products, Would buy from again
