### 3/5 — Not worth time

*2025-12-16, version 1.3*

App does not recognize my phone being connected to Bluetooth

### 4/5 — It works

*2025-01-08*

This app is meant to be used only with the HK Onyx Studio 4 model. It does what it’s supposed to, which is very little. Unless you want to setup your two speakers as a stereo pair, you don’t need this app. All the bad reviews are from people who did not read the app description and tried to use it with other Onyx Studio models.

### 1/5 — Pésima aplicación

*2024-12-08*

A pesar de qué la bocina ya está emparejada con el dispositivo, no lo detecta la aplicación y por lo que veo hace más de dos años, no la actualizan, lástima por ser una marca tan buena

### 4/5 — Updated app works flawlessly

*2024-10-04*

If you have Onyx 4, good news! Stereo mode works fine with the latest app update. It is important to pair to only one of your speakers, and let HK Connect handle communication to the second speaker. If you pair to both speakers, it will fail to start stereo mode or have other issues. The only issue is the stereo mode goes back to party mode after sporadically.

### 1/5 — NO SIRVE

*2024-09-20*

Para el precio de sus bocinas debería de servir para dar una mejor experiencia.

### 1/5 — App can not find the speaker

*2024-09-05, version 1.3*

I agree with the previous reviewer. I have reset everything reinstalled the app power on and off, and although the phone is easily connected to the speaker for sound, the app cannot find it. Pointless.

### 1/5 — 非常搞笑

*2024-08-30*

根本连不上 简直是答辩

### 1/5 — Application en mousse

*2024-07-30*

Ne détecte pas mon enceinte Omni 20+ en Bluetooth ou WiFi, on se demande à quoi ça sert.

### 1/5 — Não encontra ONYX studio 8

*2024-07-18*

Simplesmente não funciona, a caixa não é encontrada.

### 1/5 — Atualizem o aplicativo

*2024-07-07*

Simplesmente não funciona… todos concorrentes possuem aplicativos funcionais que são extremamente úteis. Ajustem!

### 3/5 — Onyx studio 8

*2024-06-12, version 1.3*

Can we pretty please get an app for onyx studio 8?

I’d love to see the battery life on it while it’s on. 

Thank you!!!

### 1/5 — 스피커 연결도 안 되는 쓰레기

*2024-05-23*

오닉스 8 인식도 안 됨

### 1/5 — Pésima aplicación

*2024-05-16*

No sirve no empareja las bocinas no sirve es app espero la actualicen

### 1/5 — Completely useless

*2024-04-17, version 1.3*

In short, the app doesn’t recognize my device, even if it’s already connected to my iPhone. Harman Kardon makes good sounding speakers but it’s obvious that they know nothing about and have no interest in making functional software.

### 1/5 — App does not detect Onyx Studio 8

*2024-04-14, version 1.3*

App does not work and couldn’t detect Onyx Studio 8, HK need to work more on the app.
Great hardware but no app to connect

### 1/5 — Junk app

*2024-03-31, version 1.3*

Junk app useless! 
Won’t even recognize my speaker but I’m playing music thru it.

### 1/5 — No sirve

*2024-03-30*

Pésima app, ya está conectada la bocina al celular y aún no lo detecta . Lastima el pésimo soporte de Harman Kardon

### 1/5 — Doesn't connect

*2024-03-11, version 1.3*

Onyx 6 won't connect after numerous attempts .. I can literally playing music on it with Bluetooth connected but the app can't find ? Make it make sense

### 1/5 — Unable to connect

*2024-03-05, version 1.3*

I have my Onyx 7 paired with my phone but the app says “Discovering..make sure the speaker is on…” it also does not connect to my Onyx 4 or Onyx 5. Please fix it!

### 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.

### 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.

### 1/5 — Nul

*2024-12-19*

Connexion impossible comme pour tout le monde

### 5/5 — Funciona muy bien.

*2024-03-12*

Tengo un par de HK Ónix Studio 4 y el modo fiesta es bien, pero el modo Stereo pffff, de lo mejor, Harman Kardon no me decepciona, súper bien.

### 5/5 — Updated app works flawlessly

*2023-02-25*

If you have Onyx 4, good news! Stereo mode works fine with the latest app update. It is important to pair to only one of your speakers, and let HK Connect handle communication to the second speaker. If you pair to both speakers, it will fail to start stereo mode or have other issues. Pro tip: nickname the speaker you pair to with either R or L so you know at a glance once you’re in stereo mode which speaker is set as R or L.

### 5/5 — 2 minutes - worked great

*2022-11-19*

Took about two minutes to connect to first speaker then press connect button the first then the on second speaker. There was about 15 second delay after pressing the connect button on the second speaker. They work great together. I had the speakers about 25 feet apart and the stereo effect worked well.

### 5/5 — Awesommmmeeeeeeeeee

*2022-07-13*

I just foundout I can connect 100 plus devices. I think Im selling my part time secondary Bose speaker and just getting all Hk. This is the best Speaker I have ever had the pleasure to experience. the bass (omg) and the clarity is unprecedented!!! Maverick!  The fact theres an app that allows me to connect two of these .. or 100 is seriously giving me faith (longterm) for humanity. I am impregnated now by even this day. Cheers to all #christmasinjuly2022

### 5/5 — 求更新

*2022-04-09*

官方求更新

### 5/5 — Ne pas hésiter à appeler le support téléphonique

*2021-12-01*

Bonjour suite à ma migration sur iOS 15 probablement l’appli ne fonctionnait plus alors que ça fait plus de 2 ans que ça fonctionnait parfaitement 
J’ai appelé le support via tél, obtenu sans attente 
Il m’ont indiqué comment effectuer une réinitialisation de chaque enceinte ( appuyer sur + et l’icône téléphone) après avoir effacer les enceinte de Bluetooth sur l’iPhone. 
Arrêter Bluetooth redémarrer, les enceintes vont apparaître à nouveau dans la liste ; les connecter, lancer l’appli et c’est à nouveau en fonction . 

J’espère qu’il en sera de même pour les autres…

### 5/5 — Simple but worked perfectly

*2020-12-25*

After seeing poor reviews I was suspicious but it connected to the speaker in seconds and while the app doesn’t do a whole lot, it does what it is supposed to do perfectly.

### 5/5 — Working well with my two Onyx Studio 4s

*2020-12-08*

Recently I purchased two HK Onyx Studio speakers to use in stereo mode. At first I tried just connecting them using the HK button on each speaker which works but apparently defaults to party mode. After installing this app I was able to easily switch to stereo mode. Sounds fantastic!!
Don’t know if this matters but in my case I only paired one of the speakers to my iPhone. I then connected the other speaker by using the HK Connect button on each of the speakers. I have not tried pairing both speakers to the iPhone as this doesn’t seem necessary.

### 5/5 — Os problemas foram resolvidos

*2019-11-30*

Aprovado!

### 5/5 — Muito bom cumpre o que promete

*2018-07-31*

App com alguns recursos úteis como interação com a Siri mesmo o atendente quando vendeu o produto disseque não funcionava. Fui procurando aqui e enfim  achei a opção . Qualidade de áudio excelente. Graves muito limpa e sem distorções . Ainda não testei o recurso com mais caixas mas vou comprar outra pranche como fica
