Bluetooth Aux Receiver, Portable 3.5mm Aux Car Adapter, Bluetooth 5.0 Wireless Audio Receiver for Car/Home Stereo/Wired Headphones/Speaker, 16H Ba...

It has everything I could need with this product, it's small and thin, lightweight, has plenty of battery, feels like a quality build, easy to connect and use and charge, and doesn't make some annoying sound and scream out the name of the brand when I turn it on like a bunch of Bluetooth devices (mostly speakers I guess) like to do. 10/10 would buy again, but I doubt I'll need to.

This bluetooth transmitter works great. There is almost no lag, and sound quality is good, and battery lasts long, and a range is great. Im using it with my retro Technics set to listen to a music from my phone on those old big speakers. I recommend it!

This is great and the Bluetooth connectivity is awesome. I love the fact that it automatically reconnects to my iPhone with just a touch of the button and it is super easy to shut down as well with a simple button press. Having both a cable and the hard double ended male adapter were a must for me as I feared that the double male adapter would break off. Both connections work well. The sound is great and it works well with the iPhone playing ZeeBooth Music, Sirius, Apple Music, etc. I was impressed with the quality of the sound and the quality of the signal. My only disappointment was the level of the volume. I typically listen to my music a bit on the louder side and to get it up to the volume I like it required turning up the volume a fair amount on the iPhone and on the car stereo. Just a minor annoyance I can live with for the flexibility of being able to stream music to my car stereo. Drop in a Class D IC audio amplifier and this is a home run.

Does what it is supposed to do. Very easy to charge and use. Dont charge while using. Mine makes an audible hum when charging and playing at the same time. Volume needs to be adjusted between playing music and taking calls.

So I've tried it out for over a week now both in my car and connected to a sound system and it's worked great every time. I've used it for streaming podcasts in my car and streaming music to the sound system. Even with all that use, my phone reports it still has 80% battery life. So I guess we'll see if that suddenly drops to 0% or continues to gradually decrease. The only issue I had was when I first received it, in order to power it on, I couldn't have the audio cable connected. After that and the initial pairing, I simply just hold the power button for 2 seconds and it turns right on. I also just hold the power button for 2 seconds to power it off if I don't want to wait. So if you've charged it and it won't turn on, disconnect the cable from it and hold the power button down for about 2 seconds, then plug it in to the audio adapter or cable. The volume has been plenty loud in my car. I hear no difference with the wired or bluetooth connection. (I currently have an older android phone with a headphone jack). Using the sound system it was also plenty loud, too loud in fact that I turned down the sound system. In writing this I realize I haven't actually tried the volume buttons on the side so that also could help make it louder or quieter. Pairing it was simple with my phone. I've also had another friend pair to it and didn't have a problem. In all instances the phones have been pretty close so I can't speak to the distance but in my uses for it, it will always be within 6' of my phone anyways. It does speak the words paired so you know. Pros: *Small, like really small. *Good battery life (so far) *Sounds good. *Good volume output. *Comes with handy audio adapter and cable *USB-C for charging. *Affordable Cons: *When used in car during a phone call, sounds a little bit distant but my wife hasn't ever complained she can't understand me or can't hear me so this is just a minor con. *Comes with the shortest charging cable. Don't know what car you could use that in to charge and also have it connected to the stereo aux jack. So you will need a longer USB-C cable. *Nit picky here but I would prefer the blue led to just stay solid when paired instead of pulsing. I don't really notice it but I haven't also driven at night so I don't know if it would annoy me or not. Just be aware that the light alternates blue/red with it isn't connected and then pulses blue when it is
