My car has an aux connector but its factory head-unit doesn't support bluetooth. I contemplated for a while whether I should go for one of those transmitters that socket in the auxiliary/cigarette power outlet, a tiny MP3 player or this UGreen transmitter (all found on Amazon). I wanted physical volume and next/previous buttons in order for me to easily control the device and so I could keep my eyes on the road (very important to me). I decided to go for this UGreen transmitter connected by bluetooth to my smartphone and I gotta say I'm not disappointed.The device comes with a double sided sticker so you can mount it to whatever space you like. I did this and it holds pretty firm (see pic1). One thing I really like about mounted it as opposed to not mounting it, is that you can control the buttons blindly. Speaking of buttons, they work good and control the connected bluetooth device, so for example, when you press next/previous, the command is sent to the phone. Same for volume. The power button sends a pause command which is pretty handy. I also like that the device powers down itself when you're not connected anymore. This is pretty convenient so you don't have to power it down manually when you exit the car. The device supports the SBC and AAC codec.Some dislikes: as seen in the spec sheet (pic2), it doesn't support LC3 codec. Also, holding next/previous button doesn't time skip.Note: the device does NOT come with the 90 degree USB socket as seen in pic1.

Works fine, auto switch on when connected to charger is plus.Unfortunately get a lot of complaints on the speaker (too much echo).Cannot use it for calling, but good for podcast listening.

I have a 2007 e350 and it works flawlessly on it. The sound quality is the same as if I was playing through aux, theres no delay, battery lasts a long time and it charges quick. The only thing I dont like is that it flashes when playing music, its a little distracting. Other than that its perfect

Great Product for wired headset users!I purchased this because it seems to be the largest (300mAh) and nicest (for its size) battery based bluetooth receiver for the price - i wanted to ensure that my M50Xs (wired headset) would work well with it in terms of longevity and music clarity. Its also Ugreen; the reviews speak for themselves. The rest of the features (bluetooth 5.4, LED screen, etc) are just a great bonus!Well, it arrived at 75% battery, lighter then it looks; ive been listening at vol 10 (66% - loudest id prob use them at) for the last 2 1/2 hours and its at 72%. If that changes heavily ill update my review.There are plenty bluetooth receivers out there; none like this. Wired headphone users (and car AUX users), this is the one. Would buy again.---Note: UGREEN, please update your last photo; it shows the back of the device listed at 400mAh, which is obviously incorrect. Thanks!

Finde ich klasse. Erfüllt genau meine Vorstellung. Anbindung ohne, dass ich das Handy bedienen muss und dennoch alles handhaben kann.Ist klein und passt gut hin.Würde ich wieder nehmen !

Bon rapport qualité prix, fait le job 👍🏼

Buen dispositivo, conexión sin problemas, buena duración de la batería, incluye cable tipo C para la carga y un cable auxiliar aparte adicional.
