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

Way more than what expected for the price . You can use in so many different ways .make any Speaker Bluetooth wireless battery lasts a long time or you took all day to cut grass when I do my landscaping business I recommend it . Because of being so small it’s hard to find sometimes when you put it in your stuff just the only issue I’ve had some time to get lost and I can’t find it.

Works as advertised. Battery is good for a full day but must be recharged overnight or will not last into a second day. Would have given 5 stars if the battery lasted a little longer. For those who are looking to plug this into something a little more active than your car (I.e. I use it in a ski helmet) the plug is strong and holds well.

The pairing capability is the first thing that is annoying about this product. It connects easy enough, but once you disconnect, it needs to go through a whole new pairing process to re-connect. Most times it makes you "forget device" and reconnect as a new device all over. Each time. Annoying. Next, it won't function while charging. Final straw, after continuous use for about 45 minutes, the connection begins to "skip". The only solution I've found is to disconnect, power the unit down, power back up, and reconnect. See above for difficulties in reconnecting. I would NOT recommend buying this product.

I was excited to receive this but then a little disappointed with performance. Ended up modifying it to use an external 18650 LiON battery and to use the headset microphone as not a default option. My only use is to connect a headset via Bluetooth to phone or computer. Pros: It was easy to connect to phone and the audio playing through the headset is great. I did not notice a video lag when watching videos. Small and lightweight. Easy to open up and get at internals. System messages given in English. Cons: I would only get 20-30 minutes from the battery running a full size headset with over the ears speakers. "Low Battery" was a phrase I heard more than once. Smaller in the ear phones might get the 8 hours they promise. Internal battery when tested was around 65mah which seems about right for size (8mmx3mmx30mm). Now I have an 1800mah 18650 powering it and get hours of use. The headset microphone is not used by the original setup even though the jack socket could support it. Ended up removing the microphone on the circuit board and wiring up the headset microphone to Bluetooth. Unfortunately, it sounds like an aircraft pilot talking to control tower over the radio as not as clear as when plugged directly into phone or computer. Note the wiring is so small you have to be comfortable soldering with magnification to do the modification. Very easy to open which means if it gets dropped, it could fall apart. I was able to make it work for my purposes. If you don't have high expectations, don't need to use the headset microphone, don't need to use power-hungry full-size headphones, don't plan to drop it, then this will most likely work for you.

I bought this to use with a 3.5” audiojack to airtube connector so i could use an earmold earpiece to receive gps instructions while driving and not have an ear constantly blocked with a bulky bluetooth headset. Although the built in clip was perfect for placing on a collar and it has excellent volume, the bluetooth ends up disconnecting often. I my phone paired to both my cars audio system as well as this unit. Normally ill connect my car first to the phone and then whatever bluetooth Headset device i am using for gps. This normally sets it so that my headset is in use and if i turn it off it will go directly back to my cars system. With this unit it keeps switching off and making my car the primary reciever. There is also a delay when this is connected to my phone in recieveing gps instructions if the unit has been idle for awhile. This ends up making me miss turns as i don’t recieve the instructions in time. I originally selected this unit for its small size, cheap price, built in clip, and bluetooth 5.0 support. However these issues with delay and switiching from being the active device makes me not able to recommend this product until a fix of some kind is available.

Gives you the ability to use your phone in an older car without Bluetooth function. You can listen to the music on your phone and have handsfree calling. Great price and holds a charge for a long time. No wires and is extremely is to use and set up.

If used to plug into your car stereo, be aware that with the male-to-male 1/8” adaptor, it sticks out quite far and the adaptor will bend or break if brushed with a coat or something. I recommend getting a short 1/8” cable with right-angle plugs to avoid this problem.

I had been using a similar product to this one for over a year with no problems, but I decided to upgrade as the other one was around $5. This is not a good product. The sound quality is poor when used for calls. It works okay for listening to music/other audio, but if you need to make calls with a hands-free device, look elsewhere. I also have problems connecting to BT and have to turn the device off and back on twice for it to work. Mine also fell apart within the first week of use. I was able to get it working again, but I had to go back to using the cheaper one that was better quality.
