I have the CSL BT receiver got me in order to play mainly on my car stereo music from your phone, since I am no longer satisfied with the Aux cables (cable handling, plugging and unplugging the connector wear out on the phone, etc.).
I am very satisfied so far with the BT receiver. I use it both in the car and at home in a very simple 2.1 sound system. Coupling with my phone (Nexus 4, Android 5.1+) works flawlessly. The battery lasts a long time (about 6 hours). The sound quality is to my satisfaction - while still in the car, I have a high-end audio system, neither at home. In the vehicle are always road noise heard, so you can not expect a sound experience there anyway. But even at home, the highs, lows and mids come out not bad. Maybe a little less strong than the turntable.
You can also charge your device while listening to music. Disturbing noises I could not discover.
The housing is made from 100% plastic, which is, however, quite well made, very allerdinsg also shines - which does not bother me personally. It offers a surprising kept simple and elegant. The blue, green and red LEDs give the user feedback about the connection status and battery status (red LED). There are two buttons on the receiver: one to the attachment or off and the actual Bluetooth activation switch in which similar to the receiver with the phone after first connecting coupling. The connectors (USB, Aux-Out) are respectively opposite angeodnet, so on both sides.
For my purposes perfectly adequate and priced ok. I would the device to others. How does the sound quality of high-end hi-fi equipment behaves, I can not say unfortunately. But can decently hear music in principle to it.
