It works from the first day without any problems. Fast and immediate connection with the mobile phone. The battery lasts quite a while, the sound on calls is quite satisfactory.

Perfect
The sound is exactly like the aux cable

I haven't tried the calls. Probably though, with adaptation to the steering wheel or mirror it would be fine

The plug within 2 months loosened, resulting in improper functioning.... I had to constantly change its position in the hopes that it would work, but in vain.... At first, I thought it was a problem with the aux port of my car, which I replaced, but still the same issue.

Good connectivity without significant desynchronization, its autonomy is okay but it requires power supply and finally, the microphone is unacceptable. It is perfect for music, but for calls, get something else.

For the money, it does what it promises. Fast connection with the phone, you can easily listen to your music in the car. The battery lasts at least 3.5-4 hours in a row. I have been using it for over a year.

I tried it for 9 euros and it does exactly what it promises, nothing more, nothing less. I plugged it into the AUX, connected it to my phone, and everything is OK. It plays my music perfectly and calls are clear as well!

I have bought worse... but there are also better ones of course! For its price, it is decent. The connection is easy and fast, it immediately recognizes Bluetooth. However, its sound is not anything exceptional (especially during calls)! The battery seems to last at least for now, quite enough! It is nice, convenient, and discreet

It connects easily and quickly to the mobile phone, the only negative is that it is not stereo and there is no bass anywhere.

I really enjoyed it because my phone does not have a relevant port to connect a wired mobile to a car stereo so that I can listen to my music. Unfortunately, during calls, I am not heard well, I am heard remotely and with difficulty, so I do not use it for this reason.

The plug loosened within two months, resulting in a poor connection and the music sounding bad

Honest
for the price of 10 euros including shipping, it's perfect. I made a hasty decision to buy it without much thought, but it didn't disappoint me.
I've had it for 2 months and I have to say, it's easy to connect with my non-Apple devices. Only one at a time, though, but what can you do. The microphone is 2/5 because the microphone for hands-free calling is better, but there are no issues with sound quality. When you forget the device in the car, it makes a white noise if nothing is playing and it's not connected. Very convenient device

i bought 2 of them, first one worked 1 year, for the price it was ok. İ bought second one and not worked 1 week .

Very convenient. It works perfectly for music and calls. It has a built-in microphone, which is not very good and is somewhat far away when answering calls, so it doesn't sound good. From the settings of the mobile phone, the audio input for calls is disabled, so you can use the mobile phone's microphone and have the quality you want.

Good connection with the smartphone, but when I speak on the line, the person I'm talking to hears me as if I'm far away from the device. I only use it to listen to music, and the sound quality is good, but for some reason, it doesn't have a crystal clear sound and the bass is low. When I connect the smartphone with the car's audio system using a wired connection, the sound is perfect. If anyone has a better recommendation, I'm open to any suggestions

Very easy and fast connection. Clear sound and at a very high volume. I haven't encountered any problems so far. The only possibly negative thing is the Bluetooth microphone, as you have to speak quite loudly for the caller to hear you.

Cute little gadget, easy to use and cheap. I haven't had an external Bluetooth before to compare, but it has acceptable performance for calls (of course much poorer than the one installed in the car) and good for music

Wonderful, the only downside is perhaps the charging port, which doesn't seem very sturdy, but this could be addressed with a magnetic termination of the magnetic charger. Otherwise, it has even autonomy, you don't need to charge it simultaneously while it is connected.

On the third day, it disassembled! It's a shame because the company had left me satisfied with other products.

For the price, it's very good! If you need it for listening to music in the car, I give the product 5 stars!! Unfortunately, it doesn't support phone calls properly, the sound quality is not good, and the call receiver can't hear you clearly. Other than that, I've had it for 2 months and it has been helpful for my trips, the battery lasts for 2-3 hours when fully charged.

I use it in the car to listen to music through my phone. Very good for its price, clear sound, doesn't disconnect, very easy to use. It has slightly lower volume than the car radio, but it's probably normal.

Very good product. It connects easily to the device and the sound is very good and clear. Of course, I only use it for music.

Quite good for its price. Clean sound, strong bass, good battery life. It is very easy to use, and I haven't encountered any problems so far with the 2 Android devices I have connected it to. It is quite small and fits perfectly in all cars that have an aux. I don't give it 5 stars because the sound is the same as an older Bluetooth Aux that I had bought for half the price from an online store. I have been quite satisfied so far. I recommend it, but there are cheaper options that have the same sound quality. The only somewhat negative thing is the volume, which is slightly reduced, but if used in a car, it can be easily increased through the car's sound system. One quite positive thing is that there is no distortion in the bass and overall sound.

Easy connection, if someone wants it for music it's great. Unfortunately, for phone calls it doesn't transfer the sound well, resulting in the other person not easily understanding what you're saying.

For its price, it is very good. Its only flaw for me is that its volume is very low, meaning you have to turn the radio all the way up to hear it. However, its microphone is quite good.

In general, it is good and user-friendly. For someone with specific requirements, it is not suitable.
There are two things missing. Firstly, it is not very powerful, even if you turn up the music source and the device itself to the maximum. Secondly, it is Monophonic! Meaning it does not transmit stereo sound. Unfortunately, the description in the store where I bought it was misleading. It mentioned the word "Stereo". However, later on, I realized that they were using the word "Stereo" referring to something like "I have a great stereo in my car" or "Darling, turn off the stereo, you're hurting our ears", and other cute expressions from the 90s, referring to Hi-Fi or the car audio system. It is unfortunate and misleading to use the word when the Bluetooth is Monophonic.

Very good connectivity and response regarding Bluetooth.
During calls, indeed comfortable communication, good quality as a source to the speakers but with a mediocre microphone performance.
As a digital audio media player mainly, nothing special beyond what is expected.
Super value for money!
*Used for about 10 days, using it as an intermediary between iPhone 6s and Pioneer car audio system

This specific Bluetooth adapter is very helpful and the battery is excellent, both for calls and music, and I haven't encountered any issues so far! Also, I must say that the pairing was very easy! I highly recommend it without hesitation!

Very good, I have it for 3 months and it hasn't given me any problems. Also, the battery lasts for 2 days at worst.

For the past two days, I have been satisfied. You connect, you talk, end of story. Whether you charge it with a USB or plug it into the car lighter. I will update in a month about its performance!!

*The watermelon is actually bad. No one hears me when I speak...
