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 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!

Works really well but has some interference from other Bluetooth devices and other cars. It seems the charging from it also isn't the best, but it works overall solid product, especially for the price It's also really easy to use, although probably a little bit bulky you just plug it in and set the radio to the frequency and the name for the Bluetooth is on the screen

That was a value buy to replace and ageing transmitter. Its performance has been much better than expected. The treble, bass and overall clarity has been spot on!And if that was enough, the Bluetooth function for placing and answering calls actually work!!! Setup was simple and the voice quality on the calls is pretty good. This is a real plus for me, because the Bluetooth module on my car stopped working and a replacement was unavailable and would have been cost prohibitive away. This little gadget works every bit a good for a mere fraction of OEM.I couldn't be happier with this purchase.STRONGLY Recommend.

This is a fantastic FM transmitter! It connected to my FM truck radio just fine and it was silent, which means the signal from the transmitter is excellent and solid. HOWEVER... When I started driving to work, another station was trying to horn in, so if you experience this, you need to drive around while a clear FM channel can be found with the Nulaxy unplugged. I also found the noise floor would come WAY up when playing tunes from a thumbdrive, ANOTHER hard lesson!...In all my years in radio and TV engineering, I've never seen that happen. To solve this, I just looked for another clear FM freq and voila, the noise floor stayed decently quiet.The bass and treble controls seem to have about a -5 to +5 dB range (just like the display says), not bad.Not sure if I'll use the bluetooth option so can't say if it's good, mediocre or terrible. I just wanted something besides my old cassette tapes to play in my 2000 Tacoma pickup, which BTW, the tape deck still works perfectly fine, good ol' Toyota quality, you know. Just wanted something a little more modern.And for those who think it doesn't have enough bass remember this...FM transmissions are supposed to be as flat across the audio spectrum as possible. Being the chief engineer for several radio and TV stations I know this to be true. Equalizing or coloring the audio is only supposed to be done after the signal is received, not before. You will note the Nulaxy only has a +/-5dB bass and treble range, which is MOST EXCELLENT for an FM transmitter that's suppose to output flat audio.
