Title: WOW, I was surprised by how good this is!
Review: This little device works great and the sound quality is excellent. It auto connects to the phone every time I get in the car. Such a little, simple, device that works very wellThe ONLY thing that is somewhat annoying is that it has a circle of light, which can be turned off, but it ‘pulses’ to music and voice. That problem is that it must be turned off every time you use it. So it is defaulted to ON, and the user has to turn it off every time. I only find it annoying at NIGHT TIME driving. I suppose if I was 12 years I would find it “cool” (or whatever the term is the kids use), but I just find it very annoying at night. During the daytime it is not bright enough to matter. At night it is like a pulsing beacon in my cigarette lighter power adapter.

Title: One of the best bluetooth FM devices I’ve owned.
Review: I am very impressed with this device both in functionality and sound quality. While the quality is not as as good as when I used to be able to plug my previous phone directly into my car, it is as good as any FM radio station I listen to.One of the best things is that it doesn’t interfere with the regular bluetooth connection between my phone and the car. I was able to easily turn off the phone call setting for the device on my phone and still have full control of phone calls from my car.The only thing I don’t like about the device is that it turns the volume on my phone up all the way after I start the car. Since I typically don’t have any audio apps opened on my phone at that time, this means the alert volume gets turned up and I have to turn it all the way back down to vibrate only, which is where it was set to begin with.I have also found that the sound quality is better when you can choose a lower frequency number FM station. I have mine set to 88.3 and the sound is noticeably clearer than when I tried other open higher frequencies.

Title: Great so far
Review: Easy to set up and use right out of the box. Signal strength and Bluetooth great – no issues. Very clear and much louder music than previously used Sosche device. Now it sounds great even at half volume. The charging ports are perfect – 1 USB-c and 1 USB standard so I’ve got any device covered that needs to be recharged. Fast charging too. Excellent.

Title: Works well – Great price
Review: Works well, good sound quality even with phone, nice and compact, easy to setup, my phone connects quickly! I don’t like the flashing light, and you can turn it off, but you have to push the button every time you power it up. Recommended!

Title: Better than most
Review: I’ve been looking to replace and older Bluetooth transmitters (2020 Vicsing) that I had for years previously. This was my 7th potential replacement that I’ve tried. Of all of them, this was the best so far but, it still not exactly what I need.PROS: The sound quality is great. The music playback is excellent with the bass booster. The volume is appropriately loud enough that the music sounds like it’s playing directly from my car’s audio. I didn’t experience static or noise interference.Call quality is also great. The noise cancellation feature is really effective in this device. People hear me loud and clear and it doesn’t pick up car/road noise. The microphone picks up clear as if I’m using the speakerphone on my iPhone.On many of the other devices that I have tried, I found that I either had really great music quality or great call quality but not both. One would have The bass boost function, but lack the noise, cancellation feature for calls or vice versa.It has an usb-b and an usb-c port which is great for charging. My phone charges relatively quickly.Despite missing some of the things I was previously accustomed to, I thought I had finally found the perfect replacement. BUTCONS: A minor con, which wasn’t a dealbreaker for me was the fact that it did not announce that Bluetooth was connected upon turning on my car. Instead, you get two beeps one to let you know that it’s on and two to let you know that it has connected to your phone. I was able to adjust to that.Another con is the playback, skip and reverse function. In order to do so with this device, you must click the call button twice and then turn the dial left to go back or right to skip forward. I have a 2006 Honda Accord where the cigarette lighter is in the console by the gearshift with a covered door on top. The cover naturally wants to close when there’s nothing in the cigarette lighter so unfortunately it rests on this device. It’s a pain to have to look down make sure I’m clicking the right Great button and then kinda holding the cover up so that I can turn the knob at the same time. This is especially annoying when you click the call button twice turn the lap right to skip and then decide you want to skip that song too. You have to then click the button again and turn the knob as opposed to being able to click. Keep turning the knob right. You can do that if you make your decision to skip within seconds of doing the previous skip otherwise you must start the process again. Other devices have a dedicated button to press or a joystick function to move ahead.It is not a great set up, but I could deal but another con made it impossible for me to overlook this drawback. That last con is – unlike other devices that will use Siri to announce who’s calling from my contact list, this device uses its default programming that I cannot override. It announces the call by saying the entire phone number (country code, area code and phone number) ALL OF THEM! So, you’re literally listening to over 10 digits being called out whenever a phone call comes through. I find this incredibly annoying. I would rather it not announce anything at all as if this is the only option. Imagine trying to listen to music and that breaks in and then you have to fumble with the button to accept the call. Declining the call was not easy for me so if I didn’t want to take the call I had to listen to the whole number so I wouldn’t be distracted while driving.This drawback in conjunction with the awkward skip playback feature makes it a dealbreaker for me. I will continue to look for devices that don’t have this these shortcomings , and also give me excellent audio quality like my old transmitter. I know it’s possible. Overall, it’s a decent transmitter if you don’t mind the awkwardness of having to use the skip feature and not being bothered by the annoying phone number announcement when calls come through. To find a device with both great call quality with noise cancellation AND good music playback with bass boost is really rare. Even devices that claim to have both, usually one feature suffers a bit more than the other. This device got it perfect. Unfortunately the cons just don’t work for me.

Review: Manos libre y música desde el móvil al coche. No hay que olvidar que la máxima calidad en este tipo de aparatos la marca la señal de radio. Así que nunca se escuchará la música igual de bien que directamente del propio equipo de música del coche. Pero dicho esto, este aparato da una calidad de música excelente y aprovecha al máximo la calidad de la señal de radio. Fácil de instalar y usar aunque hay que trastearlo un rato para habituarse. Para poder vincular el teléfono a un coche que no tiene equipo con Bluetooth, es una opción de las mejores.

Review: Répond parfaitement à ce que je souhaitai et même plus avec sa compatibilité avec Siri.Le son diffusé dans les hauts parleurs est parfait tous comme celui envoyé par le micro lors des appels.Simple d’utilisation car il se connecte automatiquement au téléphone lorsque je démarre aucune question a se poser.Maintenant plus qu’à voir sur la durée mais après une dizaine de jours d’utilisation je suis conquis par le produit

Review: Second FM sender I have tried with nearly identical design characteristics, so I’m guessing same manufacturer. Same problem with both, just suddenly stopped working, no power coming through, tested in different vehicles and never more than 12v.I’m guessing designed to fail or some very weak quality parts that can fail easily.I had a different type that lasted nearly 3 years, but it came down with a bad case of the high price increases!These latest one lasted 2 weeks past it’s last “return by date”, what a surprise.I’ll have to buy something a bit more expensive!Shocking return policy! 30 days ffs

Review: I’ve recenty bought a car that doesn’t have usb or bluetooth. But with this device I didn’t need one! After setup it’s so easy to listen to your favorite music or make handsfree calls.As a bonus you get to see your cars battery voltage, wich is nice to have.

Review: It is sturdy and well made.This works great for getting your vast music library off your mobile phone onto your cars sound system though there is some audio quality lose due to transmitting the music from the phone via bluetooth and then converting it to an fm transmission.I would recommend using the bass boost to help counteract the audio loss and the sound of the road.It happily charges two devices fast via the usb sockets so no excuse with having your phone battery run flat.It has controls for adjusting volume, pause/play and changing tracks forward and back.It also has functions to work as a handsfree device to answer the phone but since I dont use the phone at all while driving I have not tested this.If I had any criticism for this it would have to be:1. It has an always on pulsating light which is dim during the day but depending on the car maybe distracting to the driver while driving at night.2. it should switch controls for volume and track forward./back. Currently you can just twiddle the dial and it changes the volume but if you press the play button twice and then twiddle the dial it will change track. This is pointless as realistically speaking you would use the big volume knob on the radio to change the volume after setting the FM transmitters volume to a balanced volume with the in car radio and cd player. This would make it alot easier to play and change tracks while driving as double pressing the play button is destracting. It doesn’t really bother me as I remove all songs from the playlist before I set off.All in all I think its a great bit of kit with a few shortcomings but well worth the purchase.
