    SOLID CONNECTIVITY  |  GOOD SOUND  //  BASS NOTES STRUGGLE
  

*by A***N on Reviewed in the United States 🇺🇸 on December 14, 2017*

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
  

*by G***. on Reviewed in the United States 🇺🇸 on August 29, 2017*

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.

*by D***. on Reviewed in the United States 🇺🇸 on May 10, 2017*

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.
