Harman Kardon Onyx Studio 4 is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Great home bluetooth speaker I love the sound quality of the Onyx series. And the Studio 4 is true to that legacy. Deep base, but the highs and mids are still very crisp and clear. The Studio 4's now have stereo or party mode when paired with another Studio 4. The Studio 4’s really fill a room. The new app is pretty good too. It doesn’t have and EQ, but it controls the stereo and party mode nicely. The Battery life is better too. For in home use or on a patio they are great. But the downside is that they are a little larger than other Bluetooth speakers, not water resistant and charges with a larger power brick and not USB. So they are less travel friendly. With the new HK connect+ features and longer battery life the Studio 4 is a solid choice in the market of higher end home type portable Bluetooth speakers. If I were looking for a beach or camping speaker I'd probably look elsewhere. Or I needed just one speaker to serve all purposes, I'd probably look elsewhere. As an added note, the Studio 4 does have the 3.5mm input jack in the back. And they not backwards compatible with the Studio 3 or the Onyx Mini for wireless connectivity.

Hi, when I connect one Onyx 4 to my computer via Bluetooth, how can I pair another Onyx 4 in stereo mode? On my phone, I can use the HK+ Connect app, how about other non-cellphone devices?

Asked by: Question
Unfortunately, without the HK CONNECT app there is no way to pair multiple ONYX STUDIO 4 together for stereo mode, if the source is a computer as of the moment.

Can a microphone be plugged into the aux input?

Asked by: Jennym
No, the aux port on an ONYX STUDIO 4 is only meant for source such as MP3 player, Smartphone, or Tablet. Besides, ONYX STUDIO 4 already has built in microphone.

How do I connect the HK speaker to my iPhone to play my Sirius radio?

Asked by: lorie
First, put the ONYX STUDIO 4 into pairing mode by pressing the Bluetooth button until it's blinking blue led light. While on pairing mode, you just have to enable the Bluetooth of your IPHONE then pair it with the speaker. Once paired, you'll be able to play SIRIUS RADIO on the speaker.
