Mini Bluetooth Receiver, RIVERSONG Wireless Bluetooth 4.1 Receiver Adapter Bullet, Hands-Free Car Kits with 3.5mm Aux Jack Receiver for Audio Stereo System Headphone Speaker (Silver)

Overall I think this is a sound product. I had a couple of hiccups because the diameter of the product was too large for the headphone port on my headphones. I mean it was a 3.5mm, but the body of the receiver was such that it wouldn't allow me to use it. So I tried a few options including:A 3.5mm female to male adapter. (It worked but looked really bad. Also, it caught on the collar of my jacket)A 1 foot 3.5mm female to male cable. This works and I just let the Bluetooth device hang in my jacket/shirt. It is not ideal but with the headphones, I am using there was not a lot of room for other options.SOUND QUALITYHonestly, the sound quality is more like three stars. It really struggles with the lower notes in music. Bass notes are reduced to garbled sounds. This is less than ideal. However, I mostly use my headphones for rocking out to good audiobooks, so it works for me.BLUETOOTHThe connection has been solid in every environment I have tested it in. Whether it was used with headphones or an auxiliary port in my truck the connectivity has been solid.

This works well and is a great little device, if you don't have a newer car with built-in Bluetooth. However, the on/off button is also the indicator button, so sometimes I can't tell if I've turned it on or off unless I poke it with my nail, or remove it from the jack to get a better look at it. I usually just count to 4. I keep it plugged into the charger all the time, because my car does not charge when off, so it keeps it "alive" and ready if its always charging while driving. The sound is good, I cant tell the difference between a regular cord and this. Very handy for road trips. My son in the backseat was able to play his Spotify list without any hassle. It only plays one input at a time. It works well with "OK Google" because the mic into the phone still works well. I can just ask verbally to call or text someone, and it works. It does automatically turn off after 10 minutes of no use, which is good or bad depending how you look at it, so it must be turned on and connected, every time you get in the car.

Works as expected for a great price. And a lot less annoying than that stupid wire I was using before that would get snagged on everything and then when I put my headset down it would all fall off my desk. I will not miss those days...BUT... There's something really off with the audio quality. I'm not sure exatcly hw to explain it, but it sounds real "old" and "rough", if that makes sense. Now, I'm not the prettiest crayon in the toolbox when it comes to electronics, so I feel like I did something wrong; not going to blame the product. I have no idea what the issue could be, so if anybody knows how to fix it would be much appreciated.PLEASE, I DON'T WANT TO GO BACK TO THE WIRES. );EDIT: I did something and it works fine now. Don't know what I did but I'll take it.

This little gem is sure handy! It stays in the truck and handles phone calls and music just fine. Battery life could be a little longer, on a full charge it last about 5 hours I’d say. On continuous play I’d say maybe 3/12-4. I commune 40 minutes to work one way, and I charge this device once a week. (Work Monday-Thursday)The down side is that it is very fragile. Doesn’t seem to be constructed of durable materials. This is my second one. The first one broke during a... uhm..... position change from passenger to driver. Turns out they don’t like being kicked! Lol over all it’s worth the money, it’s about the size of a crayola crayon. Charges fairly quickly. Just be nice to it and don’t let your girlfriend kick it out of the radio by accident.

This has been very easy to use, just charge, connect, and play. The indicator lights are helpful in figuring out whether it is off or on, but do not waste battery either. Battery could last a bit longer, but I think 6-8 hours has been pretty decent considering its small size. I use it on my motorcycle and the sound has been clear as day, and it only sticks out 1.5-2 inches at most. Very convenient and works anywhere with a 3.5mm jack. Just bring it inside and charge via USB whenever it needs it. I used to do it after every day of use for a few hours, but depends on how much you use it. Retained charge decently well from what I can tell.

The sound quality was fairly poor with high distortion at normal/average music listening. Sad low end performance and iffy battery life. Would be cheaper to buy Bluetooth headphones with better outcome.

Omg this is the best invention since the microwave, lol. This bluetooth (BT) device is a amazing. It's small, charges quick, battery life is pretty good and it streams music from your phone into speakers of your car via Aux connection. No more cords running all over the place, no more listening to phone directly on low volume, it's just amazing. I especially love this because now I don't have to worry about areas without radio connectivity due to antenna missing, also when we travel to the northshore here in Hawaii, there is like NOOOO radio signal and it's so annoying cause the drive is so long and we settle for listening to phone by itself which is so low in volume. Not any more...also, sound quality is good and best ever, this is affordable. I'll be getting one for my husband's car too.

I love this receiver. I have an older Jeep with the Chrysler MyGig entertainment system which is actually a Harman Kardon head unit and Infinity speakers with sub. It has Navigation, a built in hard drive for storing music, hands free support for my phone... what it doesn't have to my disappointment is A2DP support for Bluetooth audio.Luckily it does have a 3.5mm auxilary audio jack right on the front and I found this receiver.No more combersome wire getting tangled up in my shift selector as I drive. This has to be one of the easiest Bluetooth devices I've had to pair with my Samsung Galaxy phone. The sound quality is great.Long trips are great easily listening to Podcasts now and music. I leave it plugged in there permanently.I couldn't be happier especially at this price.

After using this product i want to share my review.Bluetooth is easy to useNo lag between song changingSound output quality through Bluetooth is fabulous.Mic in call not ok...but acceptable.Charging ok..backup also ok.Product also too handy..Only issue is line mark observed on front side...see attached photos

This is a superb product. Slim sexy and does the job awesome . Am using it for my car and it’s rendition is superb without any delay or hissing sound. One issue is that the voice volume when a call comes is lower than the music volume.

Works fine ...good quality sound... battery last for min 2 hr

Music streaming through this device was extremely good, no latency and no audio loss. Unfortunately, the MIC quality is extremely bad. The person at the other end will feel as if you are using the phone's speaker during the conversation as it echos their voice or may sound like you are talking 2 feet away from the phone. I tried going closer to the MIC (10 CMs) to talk and there wasn't any improvement. I will not recommend this product if you planning to use it for wireless calling. By the way, I did not observe any issues hearing the opposite party.Note: Per Amazon's policy, this product cannot be returned for refund or exchanged with a better brand. All that you can do is, request for replacement of the product and Amazon will keep sending a new device of the same brand and type which will also behave the same way. The MIC quality can be improvised only by changing MIC / Chipset used in the product. Replacement of the product will be a waste of time, money and energy for Amazon, it's employees and customers.

Product is hoot but usb to charge it is very small
