Harman Kardon ONYX STUDIO 6 has the Harman Kardon brand trademark on the front. There are five physical buttons near the handle, which can control playback, adjust volume, power switch, and device pairing. Below the power button, there is an LED indicator for pairing and charging.

There is a waterproof silicone protective cover on the back. You can see a service port, a charging port, and a 3.5mm input port when you remove the cover. In addition, ONYX STUDIO 6 is equipped with Bluetooth 4.2 connection, which can connect two smart devices at the same time without re-pairing in order to switch signal sources.

Harman Kardon ONYX STUDIO 6 has a built-in 3283mAh lithium-ion polymer battery. For the testing, the volume is about 40% to 60%, and two smart devices are connected simultaneously, which can continuously play music for nearly 18 hours.

That also exceeds the official disclaim about the cruising time of 8 hours. And we can also use the 3.5mm audio input interface to play audio through a wired connection, which can save power consumption to a certain extent.

Although ONYX STUDIO 6 does not support Wi-Fi, nor does it support mobile voice assistants, it has excellent music quality, easy to carry, excellent battery life. It can also be used as decorative artwork. I think it is worth the money for audiophiles who like it.
