SONRUBluetooth AUX Adapter for Car, Noise Reduction Bluetooth Car Adapter with LCD Screen, Bluetooth Receiver for Home Stereo Music/Speakers/Wired Headphones, Hands-Free Call, 3.5MM Audio Jack

Got a set of old computer speakers that I wanted to use in my home office to play music from my phone. Bought a handful of Bluetooth receivers to evaluate (since they were cheap and seemed mostly the same). This one seems built well enough and has reasonable controls and average/mediocre audio quality.Mostly bought it for that snazzy "spectrum analyzer" display, but it seems to be a random or preset sequence simulating a spectrum analyzer and has nothing to do with the audio signal (that's not quite true; when the signal stops, the display stops). Should have known that would be the case.Decent performance for the price, but not exceptional, and disappointing display.

So... purchased this to allow my cell phone to stream music to a wired set of headphones that are also attached my work PC (via reverse splitting -- or rather combining signals. Easily do that with https://www.amazon.com/dp/B01KJTLY60 and a regular computer 3.5mm audio cable in the headphone jack).This unit synced up easily with my phone. The battery life on it is pretty good. Think I could make it about 6 hours on one charge. Never exhausted it though to find out.It produces a good sound volume level and the sound quality seems pretty good.The visual equalizer is cheezy. I think it's just there to tell you that a audio source is detected but doesn't really visually represent what is being passed through the unit. But it doesn't matter. It only stays lit for a little bit, then the screen goes dark.Overall... if you're looking for a low cost BT receiver, I would highly recommend this one.

This little unit is very light, there is a very short adapter for the audio to pass through or you can have it swing off the cable to reposition, the package includes both.Charges by USB micro, also included, can just plug it into a lighter adapter while driving takes DC5V. It is nice when companies include the cables, something they all should do.Has a call button, play/pause, and volume control. The best part is the power button is a toggle so you won't turn it off when feeling for it.The sound quality is through your speakers and the connection through Bluetooth is nice and strong, never dropped for me.I have not had a chance to drain the battery all the way, my long trips consist of less than 2 hours, and this thing still full from the constant charging.It has a belt clip for use on the go, maybe a cheap way to hook up a DAC/amp to it.There is no mention of what codec it handles, the instructions or the box make no mention of it but it uses Bluetooth 5.0, and that supports aptX.The mic is fine for what it is but it just fed sound through a little pinhole on the side of the unit, it picks up sound fine with the windows of the car rolled up.

This little box is exactly what I was looking for. I like to get in my car and listen to podcast and music. With some adapters you have to press and hold to turn on, this has a physical on off switch. Makes it simple to turn it on when I need it while driving. Then to turn off is very quick.Sound is great. I liked the included clip in case I need to attach to something.

Unit is very small and easy to clip or tuck away. It comes with the Adapters and Cables you need to connect to your Car Aux or to connect to your Receiver. It is NOT wireless where you pick a station and transmit to it, it connects to your Bluetooth source and connects your Aux or Headphones creating a Bluetooth connection. It has a clip that is good for running and walking, or doing yard work. If your car does not have an Aux, you will have to connect it to a Tape adapter or the like. Works well and no real audio loss on my equipment.
