### 1/5 — Update needed

*2026-01-10, version 1.3*

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!

### 1/5 — HK

*2025-12-28*

Une appli nullissime qui n’amène rien de plus sur l’utilisation de mon matériel. Super basic!! Aucun intérêt

### 1/5 — App will not connect

*2025-12-24, version 1.3*

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.

### 3/5 — Not worth time

*2025-12-16, version 1.3*

App does not recognize my phone being connected to Bluetooth

### 1/5 — Avis

*2025-11-12*

Nul ça ne fonctionne pas ça détecte même pas l’enceinte j’ai une hk onyx 3 et rien fonctionne c’est décevant venant d’une marque autant connu et réputer pour bien fonctionner dans les meilleurs marque de l’audio

### 1/5 — Zero

*2025-07-03*

L’application est incapable de détecter l’enceinte ( une HK Aura studio 3) alors qu’elle est connectée en Bluetooth et joue de la musique ( avec une quantité horrible de basses soit dit en passant) première et dernière expérience vis à vis de cette marque en ce qui me concerne !

### 1/5 — ZERO STARS This app literally does not work at all. Will not recognize any onyx studio 8 speakers.

*2025-06-11, version 1.3*

Tried on multiple smartphones and Bluetooth adapters. It never recognizes either speaker if you’re trying to setup stereo mode or any mode at all for that matter. Quite disappointing for the price of the speakers

### 1/5 — Intolérable

*2025-03-31*

Impossible d’appairer mes 2 HK onix studio 7 sur l’application. Manque de professionnalisme à vue de la marque et ses qualités techniques très performantes d’enceintes.
Déplorable

### 1/5 — No conecta la bocina

*2025-02-04*

Solucionen este error de enlazar los altavoces y agreguen mas modelos! Yo compré una studio 8 y nomas no conecta, ni aparece en la lista! Mejoren

### 1/5 — Will not connect

*2025-01-25, version 1.3*

App is completely unable to connect to the speaker. Speaker works great by itself so forget the app it is completely useless.
