Bluetooth Audio Adapter, Portable Noise Cancelling Bluetooth 5.0 Stereo Receiver, Mini 3.5mm Wireless Aux Adapter for Wired Headphones Car/Home Stereo System, Hands-Free Calling & Music Playing

works good

Got it 6 months ago and just unpack it. still got 80% battery. works right out of the box. The middle button is the on button. The only complaint is you can't charge it while listen, it create a static on the music. But for less $10, what more do you want. My 10yr old boom box is alive without plug in the 3.5mm cable. Excellent deal

Rudely, unusably, announces "LOW BATTERY" constantly once the battery level hits 30%. You cannot keep your sanity during this period. 30% is A LOT of time left. Why ruin the otherwise great product like this? The form factor is quite nice. The controls are predictable if you have any experience with other typical Bluetooth receivers. But good grief. It's annoying when the battery is at what I would call medium. Even if there was only 5% less, it shouldn't announce it very frequently. It's crazy.

Giving this 4 stars not because is great but because it costs only 10 dollars. There is a low level interference in the left ear (tested with multiple earbuds/headphones. The clip does not have a hinge so is difficult to place and rough to remove. Using this as a backup in the gym and works ok, sound quality is not the best (besides the interference), but is only 10 dollars. This is similar to the trusted Ericsson MW600, same shape and form, no screen, no FM and cheaper built qulity.

This was very easy to set up. Sound quality is very reasonable. But about 4 hours into a full charge it start to yell at me "battery too low..." Another thing, when it start to warn, it keeps saying it. I really don't see the point- you should save what little precious juice left in the battery for a few minute's playing after the first warning. Addition 5/28/21: Making hands-free call is not that easy. It doesn't utilize the the mike on the wired headsets. Instead it has its own mike. But then the sound quality is bad because I keep the bluetooth part in my pocket, not close to my mouth. Plus, even when I put it close to mouth the listener still complained about noise.

So far so good, it's small but not tiny,, has button interface built in, sound quality doesn't suffer and has good range of connection distance.

So few things work like they are supposed to and like they say they will I just had to write this review. It was amazing I opened the package, turned it on, plugged it in and it started working just as promised. I was able to modernize my 2007 Honda CRV sound system to accept my Bluetooth smartphone. Will wait to see how long it lasts and how it is when it needs charging. But I had to share the excitement of something that actually works for $10.

For the price, it's ok. Nice and loud, although I could never figure out how to skip or reverse with it. It was rarely unplugged, so the fact that you can listen nonstop while charging is the biggest plus. The CON: after 6 months the charging port no longer works (it wiggles inside the plastic body). So, it's now useless and will go in the trash. Mind you, it was unplugged maybe 5 times in the 6 months it lived, so use that info as you will. It's not built for longevity, but is ok for a cheap short term solution.
