Review: Lasts at least 8 hours - ***Update*** I have been using this for about 10 months, now. I have found that this lasts approx. 5 hours listening to Audiobooks, and 7-8 hours continuous music play. Audiobooks always seem to use more power. I would keep in mind that I work in a manufacturing plant that uses lots of radio signals that may interfere with the Bluetooth connection. This MAY be the reason for the shortened power availability. The device has to work harder to stay connected to my phone, therefore using more power. I wear this attached to the T-shirt, under my work shirt to protect it from what I work with. I have NEVER had any problem with the connection to my phone. And when my spouse calls, he can hear me quite well. Even over the din. Once the call is disconnected, it goes right back to what I am listening to. We used this by hooking up to the auxiliary port of a rental car over the holidays. No need to pair our phones with the vehicle BT. It worked like a dream. We were able to securely use it as a hands free device, as well as hear GPS directions and music over the vehicle speakers. The person on the other end of the phone had no problems hearing us. I still highly recommend this device. It has stood up to all I have thrown at it. And it is still going strong. ***End Update*** This is a great little Bluetooth. You use your own headphones or earbuds. It has a clip on the back for attaching to your clothes. And it stays put. I've been listening to audiobooks, so I'm sure it will last longer when listening to music. It also, doesn't take very long to charge back up. I plug it in when I get home from work, and it is fully charged in about 2 hours. I have reviewed many of this type of Bluetooth device over the years. I only buy them if they claim to last at least 8 hours. This one has held up it's end of the bargain, so far. I would definitely recommend this to anyone looking for a small Bluetooth with an awesome sound. ***For those who think the reviews on these sites are rigged...I pay the full list price on every item I buy here on desertcart.***
Review: A Great Deal - This is a great little adapter. I use it with some Shure earbuds in the gym and have been impressed with the sound quality and battery life when compared to older Bluetooth modules. No idea what kind of DAC it has, but to my ears, it’s great for less than $20. I’ve used two older Bluetooth adapters like this and they were definitely inferior in range, sound quality, and battery life. The only down side is the pre recorded voice that talks to you is too loud on my headphones. All it does that I know about is tell you you have turned it in or off. Not sure if that can be adjusted or not. Thus the 4 stars.

### ⭐⭐⭐⭐⭐ Buy it, yolo!
*by B***D on February 3, 2020*

I've had this product for a while now and have just now spent enough money to write a review and let me say, this product deserves it! The first one I received broke at the end and bent the circuit board and when I messaged their customer support they were super nice and sent me a working device for free. That may sound bad but I believe that first one was 1 in a million because my second one was top notch! The sound is amazing and I listen to my music LOUD and the 2 hour battery life statement couldn't be more wrong! I still have not had mine run out of battery and thats with heavy use. Just buy it it is more than what you are paying! My phones audio jack broke so I got this and it works so well with my phone and stereo system. Also with having this for a few momths I've had only about 2 split second audio drops out of many hours of use. Wish I could give it more stars because its just great! Rock on y'all!!
