My 2011 car was on the edge of Bluetooth, so it has connectivity for phone calls, but not for music. This little device fixes that. I just connect the phone to it via Bluetooth and connect to the car's stereo system using the AUX port. The sound quality is very good -- easily as good as with a cable.

Pairing with the phone was easy. I hear zero buzzing when it is being charged as others have said. I can only assume there is static in their car's power system, because the device itself introduces no noise. The battery is rather small but it will run for hours even if not being charged. I attached it to 5v USB port so it is charged whenever the car's ignition is on. I do need to turn it off manually or the battery will run down overnight. But even when that happens it keeps it's pairing with the phone.

This device does allow using it for phone calls if you set it to, allowing hands-free phone in the car. As I mentioned, my car already has Bluetooth hands-free phone capability so I have turned this feature off. When you connect the device with your phone you get a choice to use it for just phone, just music, or both. I chose just music.

Connectivity is good, and the device sits out of sight inside my center console storage compartment. I just have to remember to turn it off when I leave the car, but even if it runs down it starts to charge again as soon as the car starts, so I am only out of music for a minute while it charges a bit.

Highly recommended. I would buy again.

I didn't care for the rigid AUX port adapter that came with it, I figured that was an accident waiting to happen so I have it connected with a cable. As others have said, there is noise through your speakers when you don't have any music playing, but I can't hear any background noise whatsoever when I listen to music or books in the car... The only issue I have with it is people don't hear me very well on the phone, but I think that's simply because of the location of my auxport and where this is located, down low near the shifter. I'm probably going to get a couple of cables and relocate it up between the sun visors, that way it will be very close to my face when I'm speaking. The battery life is fantastic as is the Bluetooth connection range. I sometimes forget to disconnect when I get out of the car and I can go all the way into the house and upstairs and my phone is still connected (about 60 ft or so) I'm probably going to buy another one to use inside the house.

Works well and has a decent battery life. Only problems are that it connects to your device while charging so you have to disconnect from your phone every time you charge it. My item doesn't give me an accurate battery reading, it will read 40% and turn off.

I use this on my PC for gaming. I really like the fit of Apple Airpods, but they don't have a long enough battery life sometimes. I connect wired Apple Earpods to this device and connect it to my PC. I don't play any rhythm games, so I can't comment on the latency, but it has been good enough for the games that I play. I casually play MOBA and FPS games. There hasn't been any noticeable latency for me. I charge it every night, and it has never run out of battery in the middle of use ever.
