Just like the Eye Bluetooth speaker, the Diamond+ Bluetooth speaker has no buttons so it's controlled entirely via the included remote control and/or the smartphone app. Pairing is easy and is automatically done when the Diamond speaker is powered on. Once paired, you will hear a beep.

Aside from Bluetooth, the Diamond+ speaker light can also be hooked up physically via the mini USB to USB/3.5 mm audio cable included.
The Diamond+ speaker charges in 4 hours and the built-in 1300mAh Li-polymer rechargeable battery lasts around 8 hours on a full charge.
You can fully adjust the brightness of the lighting, as well as sync the lighting to the music. The Diamond+ speaker produces a rich bass that balances out nicely across the full sound spectrum.

As mentioned earlier, the Diamond+ Bluetooth speaker light can also be controlled through your smartphone via the BedTiemSocial app. The BedTimeSocial app is available for download from the Apple Store and Android Store and allows you to set the Diamond speaker to help you fall asleep and wake you up in the morning.

What's cool about this app is that it also allows you to customize the "wake up" and "fall sleep" with your preferred sound.  Also, you can record via the app a voice greeting and send it to the speaker.
The BedTimeSocial app is essentially a secondary remote control that you can use instead of the IR remote to control the Diamond+ speaker and its many light features. The light features include Reading light and Sunrise mode which is activated 30 minutes before the time you set the timer to wake you up.

Step 1. Download app                                               Step 2. Select DM+Yantouch 32 to connect
