COWIN Bluetooth Receiver/Car Kit, Bluetooth Adapter Low Energy Portable Wireless Audio Adapter 3.5mm Aux Stereo Output (Bluetooth 4.0, A2DP, Built-in Microphone) for Laptop, BTMpblie, Computer, He

The main thing I wanted was a way to watch (ok listen to) TV with my Cowin E7's. All I had to do was plug this into my receiver's headphone jack, turn off bluetooth on my phone, turn this on, turn on my headphones, wait a few seconds and I'm good to go. Simple, works every time.Nice to be able to enjoy movies without my neighbors having to hear.

Más o menos.

I needed this product to set up my Corwin Headphones to my Marantz receiver. It was very easy and works great.

I found this unit to be very noisy. It kind of disappeared when music was playing but between songs, the noise would be there. I used this unit with a COWIN bluetooth headset (which are very nice) for meetings and that is why I could hear a lot of static; because there was a lot of dead air.
