The Onyx Studio 4 stands out with its powerful 60-watt output and bass-heavy sound signature, making it ideal for those who prioritize low-frequency performance. While newer models offer refined features like self-tuning and Auracast technology, the Studio 4 maintains its appeal through sheer power and distinctive design.

Power: 60 watts
Battery: 8 hours
Weight: 6.91 lbs
Features: HK Connect+, Dual Device
The Onyx Studio 4 delivers impressive power with its 60-watt amplifier system, producing room-filling sound that can easily cause noise complaints in apartments. During my testing, I found the bass response particularly outstanding, with deep, punchy lows that many newer models struggle to match.
Build quality remains solid despite the age of this model. The distinctive circular design features premium materials that still look and feel high-quality today. However, at 6.91 pounds, it’s not the most portable option, and the lack of water resistance limits outdoor use.
Connectivity includes Bluetooth 4.2 with HK Connect+ technology for multi-speaker pairing and dual device connection. While reliable in my testing, the older Bluetooth version may lack some optimizations found in newer standards. The built-in microphone works adequately for calls but isn’t as clear as dedicated conference speakers.
Exceptional sound quality with impressive bass performance that rivals many modern speakers costing twice as much. The 60-watt power output delivers room-filling audio that remains clear even at high volumes.
Potential battery degradation issues in refurbished units, with many users reporting only 2-3 hours of continuous use. Being an older model, it lacks modern features like water resistance and app support.

Latest technology with Auracast multi-speaker connection and USB charging capability. Exceptional sound quality that many consider the best in its class, backed by Amazon’s Choice recognition.
