It is excellent for its cost. The sound is heard very well even if the window is open. My interlocutors said the same when hearing sound from my microphone. Placing it on the sun visor makes its use very easy. The sound quality, obviously, is NOT that of a sound system. After all, it uses a simple speaker. However, for the minimal amount of money it asks for, it is very good. I use it 1-2 times a day for phone communication while driving as well as on my way home listening to a podcast.

Very satisfied with the product, especially considering its price!

I have absolutely no problem talking to my conversation partner even with the windows open and engine noise. The same is said by those I talk to!

Excellent battery life! I don't know about other similar products in the same category... but I forget this one on and sometimes for entire days inside the car...

Connection with Samsung phone is very simple. 4 stars because the speaker quality – although it has volume – is not satisfactory. For music and such... okay... you can listen but it's not meant for that purpose...

connected directly to my phone and the sound is very satisfactory, it's more than worth its money

Beautiful, practical, with powerful sound and very easy connection. After the first connection with bluetooth, it connects automatically every time I get in the car. Very, very good value for its price.

Initially, it is large in size. But let's say, that's not such a big deal. Its battery lasts a long time. The sound is fine during calls. You can hear them and they can hear you. However, for me, since I listen to podcasts while driving, it has a huge drawback: I struggle to hear the audio. I gave it to my mother-in-law who only wants it for calls. From me, it's a no.

Excellent! Very good acoustics, I bought 3. I highly recommend it. Through wi-fi connection you can comfortably listen to songs as well.
