Great seller works fine

Bought 3 of them. 1 still working, another stopped working after a couple days, and the last one I bought DOA right out of the box.Buyer beware!

Worked like it should. Easy hook up.

I use it to listen to a radio on an earbud so I don't have to use corded earbuds. Once it pairs with the earbud, it is reliable and has decent range. It has a perceptible lag, but this isn't a problem when listening to a radio. Its battery lasts several hours and recharges fast. My only complaint is that it can take a minute or more to connect, and that it doesn't work with most of my Bluetooth earbuds or speakers.

Good manual.I tried it out both transmit and receive. Both worked.As a receiver I plugged the OiDiPi into a wired speaker and used it for Bluetooth output from my computer. The computer reported that the OiDiPi was at 90% charge after I had fully charged it, but I think on a first charge one might expect a lack of precision.As a transmitter, I plugged the OiDiPi into a radio earphone jack and received it with a pair of wireless Bluetooth headphones. The sound was decent (I'm hearing impaired, so no expert opinion).The Amazon product listing says "2-in-1," which it is. The manual describes both functions: transmit and receive. The BOX says 3 in 1 with the third function "hands free" with a phone symbol. Whatever this function is, it is not described in the manual and not tested by me. Usually means that if paired with your phone, you can answer the phone by pressing a button on the device.

Meh, I mean it works. But volume level is very low, and latency is horrible. It would be okay to use for a portable c.d. player, but not good for musician or instrument application.

I bought this BT adapter due to it being single channel. My current go-to is 2 channel and while it is connected to my headphones it will also connect to a set of hearing aids when not desired. There is no noise cancellation.The adapter is light and compact. It is about 1-7/8" W X 3-3/16" L X 1/2" H, and it weighs about 1 oz. It comes with a 19 inch audio cable and a 19 inch USB A to Micro charging cable end to end.It takes about a minute to connect to my headphones the first time. After that it connects within about 2 seconds. Very slight noticeable audio delay, not annoying with U-tube videos. The range for a good connection is about 25 yards through the house walls. The blue led flashes while connecting then it stays constant while connected. The light is also the charge indicator and turns red while charging turning the led purple. Amazing device for only $10. I've had it for about 2 hours. I hope it lasts.
