You can enjoy the music for up to 6 hours under optimum audio conditions. Also, it requires 3 hours to charge fully.
The speaker has a wireless dual sound. It means you can connect two Onyx Studio 5 speakers and play loud music. Please note that although you can connect two speakers, you will not get a stereo effect.
Also, it has a 100 feet Bluetooth connectivity range which is a significant advantage.
The speaker is neither waterproof nor water-resistance, hence it is not recommended to use outdoors. But, you can enjoy the loud sound in your garden when there is no rain.
Overall, this speaker is designed for home entertainment, and it will blow your mind when experiencing its monster sound. I think spending 15k is worth it for the speaker, and you will not feel regret on your buying decision.
