Appmuse

Does nothing… I was hoping to change the bass & treble on my HK 4 because someone played it at way too high volume & blew out the woofer/bass… but this app does nothing… Show more

As of iOS 16, this app works fine. My HK Onyx 4’s are playing in stereo on my first try just as the were designed. I had previously deleted this app and bought a bunch of cables and adapters to tediously wire them up as a wired stereo pair, because the app was formerly just that broken. Show more

I love my speaker… it is paired to my phone and working great. But the HK Connect app just spins and spins on the “discovering” screen, offering to tell me how to connect my device via Bluetooth. I even forgot my Onyx and re-added it, but no difference. Show more

Save your effort. Harmon Kardon apps offer the absolute minimum in functionality. I boht two Of the latest Studio 4 speakers thinking they must’ve improved the speakers since Studio 2. Stereo works, but it’s an incredible hassle to get and keep it connected. What a hassle. I guess I expected a quality experience. Nope. It’s a shabby treatment I received instead. Thanks you goofy company. Suggestion. Fix your apps and improve your speaker’s bluetooth functionality. Oh, the speakers sound great. What a shame they end up sitting on the shelf! HK? Show more

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. Show more

App wont connect to my speaker onyx studio 7 ???

Onyx Studio 4 is a great (big) speaker, but this app is worthless. Speaker connects to Bluetooth fine but can’t be “Discovered” by the app. HK support says this is a known (for years?) issue and is working on an app update. I’m not holding my breath. Show more

Probably the worst and most frustrating app I've ever TRIED to use. Still haven't been able to use it, maybe in 2050 it will find my speakers. Likely switching brands after speakers run their course. Show more

Love the speaker. Sound is amazing. But app is absolutely worthless. Cannot get it to “discover” the speaker. Doesn’t even deserve 1 star.

I have two HK Onyx Studio 4 and both are not discoverable in the app. Followed the directions and the speaker is connected to my bluetooth via settings but not discoverable on the app. Not sure how else to update the firmware on the device. Or if it’s even worth it. Wanted to see if it can connect to google assistant but doubt it. Sounds like other reviewers have a similar problem. Show more

Useless app really

Tried several times to connect my Onyx speakers to this app to no avail. Spent almost an hour chatting with a HK rep. Can't believe a company with such great product has such horrible support. I guess that is what makes Bose that much better. Show more

Doesn’t connect through app, defective software! I can connect fine not using this app. Just though if I used this app would give me different options since I couldn’t connect the app, it’s useless. Show more

Completely useless app, taking up space. Can’t do stereo at all. No other functionality really.

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 Show more

tried reconnecting bluetooth, reseting the speaker, and reseting my device. still doesn't connect my speaker to the app. perhaps it's too outdated and hasn't been in touch with current device audioware? Show more

The little manual says that is how to do it. Their website says firmware is on version 4.something. Mine is version 3.3. The app shows that but has no way I can see to update the firmware. The manual on the speaker also says the usb-c port is for updating firmware (which contradicts the manual saying you can do this in the app). At any rate, the app does not seem to be able to update the firmware. And it is over wise, to me, useless. Show more

I cant use the app It doesn’t open!

Overall sounds good, although not very crisp. Does not allow for bass/treble balance, and a lot of music the lower range overwhelms higher…in harmonies, multi instrument, etc. Too bad drives me nuts. Show more

Make a simple patch fix
