User Reviews

User reviews indicate HK Connect is frequently unusable: the app often can’t discover or connect to speakers even when Bluetooth is active, and compatibility across Onyx models (4–8) is inconsistent. Stereo mode, when it works (notably on Onyx 4 with proper setup), is unreliable and brittle. The app also lacks core features like EQ control. Overall sentiment is highly negative, with many calling the app useless and demanding better support, updates, and even open API access.

Pros

Stereo mode can work on Onyx Studio 4 with the latest HK Connect update when set up correctly (pair to one speaker and let the app handle the second).

Cons

App frequently fails to discover or connect to speakers, even when the speaker is paired with the phone via Bluetooth.
Discovery/connection problems appear across multiple Onyx models (Onyx 4, 5, 6, 7, 8) with various devices and adapters.
The app lacks essential features like EQ control, leaving users unable to adjust sound settings.
Stereo mode is unreliable: it requires precise setup (one speaker paired, app manages the other) and can revert to party mode or fail entirely.
Overall, the app is described as useless or garbage by many users, with widespread calls for better support, updates, or openness (e.g., API access).

Recent reviews

Speaker’s paired to phone, app can’t find it. Forgot device from my phone and re-paired with the speaker and still can’t find it. Just want to adjust EQ but this app is trash. Get better Devs, Harmon!

I would like to be able to adjust the EQ. The HK connect app will not even recognize the speaker. My phone recognizes the speaker. I can play through Bluetooth, but the app can’t find the speaker. It is completely useless.
