Bluetooth Audio Receiver, iCrius Wireless Bluetooth 4.1 Hands-Free Audio Receiver & Mini 3.5mm Aux Audio Adapter Kits for Headphones/ Speakers/ Car/ Home Streaming Music Stereo Sound System (Black)

I must admit I was amazed with it. The first I noticed when I open the package was that the Jack was not connected to the device itself. After looking at it exactly what I thought, I can turn any ordinary headphone or other devices into Bluetooth. I connect it with my studio headphone and pair it with my laptop so I can walk around the house listening to project that I'm working on and yes once I pair it with my phone I can use the same studio headphone to make and receive calls since the device itself has a call button and volume control knobs.

Great Bluetooth Device. The sound is loud and clear. However, the battery life is not that good. It goes dead quick.

Has a decent range at least 35 feet away from the source. I’ve only used it in the house. The sound is a little distorted.

I used this product when I was golfing and it worked great. I then went the next week to golf and tried to use the product and it said low battery and then turned off and will not turn back on. I've charged it and you can see that it is charging but still will not turn on. I have sent an email to the company but have heard no reply so the companies "60 Day Guarantee" is a joke since they won't even respond to problems. Would not recommend this product to anyone.

I love it, but it’s very low quality at least for Texas weather the plastic enclosure is starting to open also the battery sucks. Everything else is great

The media could not be loaded.  Good for the price, cheaper on eBay but shipping is slow and customer service is better on Amazon. I had no problems, worked in my car, I attached a video. Didn't work on my beats studio 3 wireless with the aux cable it came with, or with my own.Overall good and I'm happy with the 2 days I've used it.

I bought them so I could use with my BEATS. They are REMARKABLY clear, for the price point!!! I just open the package and started listening... theeeeennnn... I get an android system message reading the "bluetooth device has 60% remaining" ... Uh, Way too cool to express after less than 5 minutes having and using them from the door delivery! (Dec.31,2019) Ok, after having and using doe a while, the battery will charge to 100, but will die at 20% (everytime)

I ordered this adapter as a back-up in case the one I ordered to convert my headphones to bluetooth didn’t work. That unit worked as did this one. However, the length of this one made it very awkward to use on my headphones so I used it to replace an older one with my vintage home stereo. At first I was very pleased as all the functions worked great as I streamed form my phone. I was operating it at a relatively low level and had yet to try to really crank up the stereo. It paired easy and there were no weird quirks like audio volume not adjusting or sound dropping out like I had experienced on my old unit. After a few days I noticed I couldn't get the volume to go up above a certain level and the quality wasn’t what it could be. Even with the stereo’s volume turned all the way up, it wasn’t very loud. I would have to really turn up the knob on the head unit to get any sound volume above an average low listening volume. This led to a hiss and noticeable line noise. It then started creating a very loud buzz when I’d stop playing music for more than a few minutes and since the head unit’s volume was turned up so high I was worried it would damage my speakers.I reattached my old bluetooth unit and immediately noticed a HUGE improvement in sound quality and was able to crank up the volume as much as I wanted from my phone.This unit now sits unused.
