I recently bought this product but sadly didn't find any review that would help me buy this. Hence, thought of trying to add a review that talks about the product features, pros and cons in detail. I have deliberately added some very basic points too. Please note that my review broadly covers usage inside a car. Mine is a Honda Brio with factory fitted music system without bluetooth.1. This product has a built in battery, hence doesn't need to be connected to power always. You will be able to see the battery level on your phone screen just like bluetooth speakers. This feature is both helpful and annoying. Due to the battery, the device doesn't power off as soon as you take out the car key. So, if you have taken the key out, closed the door and maybe standing next to the car, an incoming call on your phone will get routed through the device if you are in the range. Turning the device off everytime while leaving the car can get annoying. On the other hand, the battery makes this device truly portable.2. It has a built in mic that helps you speak on your phone handsfree. The mic range is quite good and I have specifically taken feedback from people while talking if they are able to hear me clearly or not. Calls can be answered/disconnected by the pressing the call receive/end button on the device as well. So, this product instantly converts your old music system into a modern bluetooth enabled one.3. Sound output quality is excellent! If your car has good speakers, then expect a great effect.4. The device connects and reconnects(after car restart) very fast5. Device buttons are very tiny, bit difficult to use. Overall Build quality is not that great6. I had ordered seeing the black image but received a lousy white one7. Some people have rightly pointed out that it protrudes out too much when using the metal aux connector. But if you use another aux cable and keep it somewhere below, the mic range might get impacted and the other person won't be able to hear you clearly.8. This device can also help you convert your existing wired headphones into bluetooth enabledHope this helps. Would add more points after prolonged usage.

I bought this because my old Bluetooth headphone borked. Had low expectations. But I was pleasantly surprised. This thing connects to almost all Bluetooth devices and is pretty good at reception for upto 15 feet. Walls Will hinder it though so you need to maintain line of sight. Good as a temporary Bluetooth converter or adding Bluetooth to an older speaker system. The battery takes 30 to 40 minutes to charge from laptop USB and lasts for a decent 2 to 3 hours of medium volume playback.

Product is as described.It works with car, home theatre and earphone.Good battery backup.This is not a stereo, only mono sound.Sound quality good.Range is more than 33 ft.Yes it works while charge.product material quality and finishing good could be better.There is no user manual please provide with package.Fully satisfied with this product after 1year 10month use.

Pros:fast connectivity,no sound quality lost in transmission compact design.Cons :As against claimed 4 hrs battery life,mine lasts around 2/1/2 hours,big drawback.Doesn’t accept charge from a battery pack .USB port bit tacky as also charging cord ,don’t fit cleanly.Would have preferred advertised battery life.

The item stopped working properly after 1 month.1) Noise then contact via phone, before starting the music.2) Battery died after a month3) Not connecting to phone properly. Need to switch on/off couple of times.It worked find for the first 3 weeks then started the above problems.I have another Bluetooth connector ( black with out battery) from another company. It was a very good still working fine after 1.5 year. As it was not having battery, it switch off when I restart the car, so I bought this one. But was disappointed.....

Build - perfect.Sound quality - excellent.Connectivity - super fast.Battery - not very sure, but feels fine.Microphone - works perfectly.

It's a good product connects really fastDoesn't connect with home theater with a double pin but for cars it's perfect
