Ugreen-30348E is an excellent audio streaming adapter for your older devices which doesn’t have Bluetooth. We bought the device from Amazon for just AED 42. The device was bought as a purpose of using as a audio streaming device in a car that does not support Bluetooth.

The adapter is a breeze to use for audio streaming. You just need to plug in the device in your 3.5mm port and press and hold the button on the device to turn the device to discoverable mode. The device is equipped with Bluetooth 5.0 technology, We tried to connect 2 smartphones to the Bluetooth device and it worked without any issues.

Pairing the devices to the Bluetooth is also relatively easy as any Bluetooth pairing process. Turn on the device by pressing the only button on the Bluetooth adapter for about 2-3 seconds and go to your device Bluetooth settings and select “UGREEN-30348E” to complete the pairing process. There is a light indicator to know the status of the device.  Blue and Red blinking indicate that the device is in pairing mode. Once the device is connected, the light indicator on the Bluetooth device will turn Blue to indicate that the device is successfully connected.

During our review period of 3 months, we found the device as a value for money product. The music streaming output was good and found no issues with the connectivity. The music streaming quality through Bluetooth was good. However, in calls, we found that the in-built mic on the device was not so sensitive and the callers were unable to hear the voice when we spoke in normal sound.
