Works GREAT! Just as advertised, very clear sound and the USB charging are very functional. It also looks good and very solid. Would definitely buy again and recommend!! Great value for the money and very easy way to add BT to your vehicle with older stereo receiver.

Right out of the box this thing worked just like it should. I have a 25 year old pickup with no bluetooth. Plugged it in, set the frequency I wanted to use, and it paired with my phone right away. Strong signal to my vehicle radio. Awesome. I have tunes through my car stereo from my iPhone, I'm happy. It seems to function well. It helps if you find a spot on your tuning dial without any radio stations near it. And if you happen to travel and suddenly find that a radio station is using the frequency your device is using, you'll get interference and a dropped signal as the device and the real radio station fight your vehicle's radio. Other than that, nothing not to like so far.

I got this to read music from a USB drive and the sound quality isn't perfect since it's being transmitted by an FM radio signal but it's still pretty good. The only thing that sucks is that there's no shuffle option. It will play all the audio files in alphabetical order but at least it remembers which song was played last so you can cycle through the entire collection over time.The other thing to note is that the instructions say to find a clear radio band but I found that the higher bands were better, regardless of whether they were free or not. A clear band at like 89MHz sounded pretty crappy but I set it to 107MHz and it sounds very clear, even when I get to work where there's a radio station on that band.

I recently got an FM transmitter, and it’s been such a great addition to my car. It connects to my phone through Bluetooth, so I can play music, podcasts, and even take calls right through my car’s radio. The sound quality is really good, though from time to time, you might hear a little disruption, but it’s never a big deal. If it happens, you can just switch to a different FM frequency, and it’s fixed in seconds. Setting it up was super easy you just plug it in, find an empty FM station, and you’re good to go. I also love that it has USB ports to charge my phone while I’m driving. It’s such an affordable and simple way to upgrade an older car’s audio system, and I’d definitely recommend it!

Before buying this, I compared to probably 10-15 other FM transmitters, googled reviews on external websites, etc. This one showed up most consistently in reviews as having the best sound and call quality, somehow.I received it in new condition, install was a no-brainer like every other FM transmitter: plug it into your power outlet and then pair with a device. It does pair immediately when you turn on your car and seems to have strong connectivity since over a few weeks of using it I've never had any issues with my phone staying connected.The sound quality when playing music is okay to decent. It largely depends on how clear of a radio station you can find, and if you don't have access to any unused channels then your mileage might vary in terms of clarity. In my area, I was only able to find a station that wasn't entirely clear but the transmitter overwrote the broadcast with a little fuzziness. It won't sound like a CD, auxiliary input, or USB input playing, so don't expect to get crystal clear sound quality with this (despite how exaggerated some of the other reviews are). It's still just an FM transmitter.The call quality is pretty abysmal to the point of being unusable. I actually made the choice to buy this on the pretense that it had very good call quality, being one of the stand-out points many reviewers made. In reality, the quality is not good. Hearing people is fine, which is expected, since the transmitter is literally just a stand-in for your phone's own sound. If you can hear people on your phone well, then you will hear people through your speakers well, too. The issue is that even when very close to the microphone on this unit, outgoing voice sound is very muffled and quiet for anyone calling you. I have used this unit's microphone for multiple types of calls, including calls through Discord and Skype and through normal cellphone service with full signal. Always the same results: incoming sound is fine as would be expecting since that depends on your phone, and outgoing sound is borderline inaudible through this unit's microphone. This happened with both my car in park idling and in motion, so the issue is not with having a loud engine or car noise. Whatever the noise-canceling function that's built into this does doesn't actually work.The unit also does not power off on its own. So, if you have a car with auxiliary power that stays hot for a while after you turn it off, it could be a liability for your battery. You'll have to unplug it and plug it back in every time if your car doesn't power off the outlet.Other things: the unit looks fine, it's very unobtrusive and small. It shouldn't clash with much in the exterior of any car, besides the old-school orange display on the top (you can't turn it off). Depending on where your power outlet in your car is, it may be difficult to use the buttons on the sides unless you rotate it. The "quick-charging" feature is just marketing buzzwords, like everything else that advertises it, this will charge your phone at the same speed as any other USB 3.0 outlet and will be compatible only if the device itself (not the FM transmitter) supports Quick Charging.Ultimately, this FM transmitter is only better than the competition if you prefer how it looks. They all do virtually the same things and do them in more or less the same way, with the same pros and cons. Some have extra features, others are more straightforward. This one is firmly average. It won't blow your mind with amazingly clear calls or sound, like some people have reviewed.
