(Upgraded Version) Bluetooth FM Transmitter, Sumind Wireless Radio Adapter Hands-Free Car Kit with 1.7 Inch Display, QC3.0 and Smart 2.4A Dual USB Ports, AUX Input/Output, TF Card Mp3 Player

For under $30, you absolutely cannot complain. A couple years ago I bought two wired units that were cheap, cheesy, and functioned fine. I gave the one I didn't like as much away. Recently I purchased a case for my new phone, and the jack would not fit without removing the case. I figured it was about time for some sort of upgrade. I have the S9+ and have zero issues with this transmitter.Pros - Many of these pros were mostly unexpected+ Button layout is PERFECT+ Unit is smaller than I expected+ Doesn't look as cheap IRL than I expected+ Specifications are that of 2017 or 2018 for sure, I mean Bluetooth 4.2 and QuickCharge 3? That's impressive!+ Connecting is a breeze. Connect via Bluetooth and start streaming music. Turn your phone volume and the device volume all the way up and you're set+ Prev/Next/Pause/Play are added bonuses that make driving much safer+ Call audio is pretty good! They can hear me well, visa versa+ Came with an extra fuse+ Music sounds great, bass comes through as expected+ Display, a pro and a conIn the middle, I haven't really figured out how to use the assistant with this device. I don't use Bixby. Google Assistant is far superior from any assistant for my daily life. I still find myself unlocking my phone and asking Google what I need. Not a big deal to me, I didn't even expect this as an advertised feature when I was browsing transmitters.Cons - This is more or less being picky about non-issues and future expectations for a new device update- The average person will lose the extra fuse. There should be a way to store the spare fuse in an empty compartment spot inside the transmitter.- Audio quality is superb, especially compared to the two units I had before. The only downside is that you may experience minor interference or hear feedback from your car. It is so minor, you likely won't notice and there's really no reason to care. Additionally, I found some mid strong notes cut a bit off on songs, but it may have been interference or just my stock car speakers- Every time you start your car, you have to hear the device telling you it is looking for your phone, and saying it is paired. *This is definitely the biggest con*, but not a huge deal. Still better than scrambling to plug the audio jack into your phone. I wish this could be disabled, because the transmitter is so reliable, I don't need to know that it's looking or paired.- The display is a bit cheap. What else would you expect? I certainly don't need a high end display because the one it has functions perfect. In a way, the display is also a pro. I would describe the display as, 'it lags behind with changing text'. I was adjusting the radio channel to broadcast to and that was slow and tedious, but it's easy to change so it's really a nonissue.- The only other downside I can find, is the audio will not be as loud when using Bluetooth, but most people won't notice. However, it also depends on what phone you have with how loud it is when using a wired connection.So what exactly would I like to see in an updated version? Newer Bluetooth version, built-in storage for the extra fuse. It would especially be great to adjust the Assistant activation to like 1 to 2 seconds (3 to 5 is a bit long). You're pressing the button for less than a second to Pause/Play, so the Assistant should be more convenient at 1-2. The most important thing to me would be muting the voice saying that the device is scanning or paired. My other unit had the ability to scan for empty channels, but please don't add that into this device because that just means wasted space on the device and a button I'll never press. Everything on here is so functional, and it should remain that way. I would almost go as far as saying to get rid of the volume level on the display, along with "Bluetooth BT70".***Lastly, and most important of what I'd like to see in a new version, I wish there was a wheel knob or button to lower or even turn down or off the brightness. Transmitters are always annoying to drive with at night. At the very least, to keep costs down, I would like to see a button with 4 or 5 brightness settings from OFF to Bright, and not on the front but on the SIDE of the device. Software functionality could be added, double or triple tap the Pause/Play button and turn the knob to adjust brightness.***Overall, what you get for under $30 is so much value. I will definitely be telling others about this. This is especially an awesome Christmas present or birthday present! This is by far the best unit you can possibly purchase, anywhere. I specifically paid $4 for faster shipping because it's so cheap. The price blows my mind, and the transmitter rocks my car! This is a must buy!

I bought a used car back in February and to my dismay, the aux port was damaged. I (stupidly) did not get the warranty. I was hoping to use the aux port to connect my Amazon Echo or this Bluetooth adapter I had.I was very upset until it hit me - I could just get an FM transmitter. My brother-in-law has one and it works great. I went on Amazon and found this one. I read through a couple of reviews and bought it. It was something of an impulse buy, but I am so glad I did.It works very well - connects to my phone as soon as I power on my car, unlike my Amazon Echo Auto, which I don't miss. I have to turn the sound up on my phone and radio to hear anything but that might just be due to the technology. Once it's at the volume I prefer, music sounds great. For the best results I tuned the transmitter to the end of the FM spectrum and I haven't had to deal with interference with other radio stations.This unit has features that I haven't used yet, such as the aux port on the side, and I just realized that you can put in a micro SD card in it. I will have to try that out as sometimes I don't want to launch the music app on my phone and find something to play. I also love the button you use to answer the phone, and didn't realize you could long-press it for Siri (since I have an iPhone) so I will have to try that out.Initially connecting it to your device is also very easy, as I recently upgraded my phone and had to pair it again. I also love the two charging ports, as you can use it to charge anything else. I used one port to charge my MagSafe charger but I broke that cable by accident.I came back to this listing to buy it for my dad as he needs one, and remembered that I wanted to write a review for this, so here it is. I think I paid $29 for it, and it was worth every penny. It works very well and I love it.

I've used it for a couple days. It seems to work just fine.. I have noticed if you turn the volume up on your radio and use the volume control on this product. You will get a higher hum, Or background noise. Turn the volume up on the transmitter and use the volume on your radio and it's not as bad.. It's a low hum and not that annoying. Anyway product seems to be pretty good. Signal Strength, stability, ease of use, all pretty good... durability? I would have no idea.
