Onyx Studio 2 is rated 4.1 out of 5 by 118.
Rated 5 out of 5 by from Premium price, but you get what you pay for The $450 price tag may be steep to certain parties, but keep in mind that Harman/Kardon's mission is "Beautiful Design and Warm, welcoming sound together at last", and that has been Harman/Kardon's mission for almost 70 years. While you might have to omit some footage from certain music, the decibel capacity of this product (not to mention the detail you get from this product) more than makes up for it, and it complements the company's "beautiful design of products" pretty well. Not included from the original Onyx is the 3.5mm jack, and that's a welcome plus. The speaker may be too large to carry anywhere you want, but the bottom line is, you get what you pay for this product.

Rated 5 out of 5 by from Great Product So I bought the first Harman/Kardon Onyx Bluetooth speaker. Was amazed on great it sounds. Great highs and mids, though it needed a bit more bass. So the Harman/Kardon Onyx 2 comes out, immediately bought it. Again amazed on the sound, but the bass was a bit overpowered to my liking and a bit more louder with my iPhone with just 3 bars of volume. Although many like a strong bass and louder speakers, then this speaker is the one. I love it. Looking forward for the next installment. Hopefully A Harman/Kardon Onyx 3.

Rated 5 out of 5 by from Awesome, Awesome, Awesome I would give this 10 stars if I could. Literally the greatest thing I own. Got it for Christmas last year, it's been all over the world with me (literally). Amazing it's lasted over a year, the volume is never less than 100% plus it's been in suitcases, knocked around, fallen down a flight of stairs, nailed to the dash of an old plow truck, and really just beat on. Finally let go on me this afternoon- the bass got muddy, basically it's starting to blow. But of course I'm buying a new one! Couldn't recommend this thing any more. I love it

Rated 5 out of 5 by from Great/but So to start off this speaker sounds awesome. I've been listening to Bluetooth speakers for a very long time and of everything I've heard, this is by far the best sound and well constructed speaker I've seen on the market. With that said I don't understand how such a high quality product can not come with an LED light that indicates when the battery is low and when the battery is fully charged. Even my Mini Jambox has that feature. In the future I think this is something that should be incorporated into this amazing product.

Rated 5 out of 5 by from Wonderful bass So stylish and supreme sound! I can't get enough complements on it! I am truly happy with my purchase looking forward to buying more products of Harman Kardon!

Rated 5 out of 5 by from Onyx Studio 2 Review Sound Quality is superb. Legs need a better design and very hard to find replacement. Only five hours of battery power. Overall, outstanding sound quality with rich bass. A smartphone adapter allows for plug in and charge while listening to music to avoid battery drain.

Rated 5 out of 5 by from Amazing sound Ive been using this for my backyear BBQ's and it sounds amazing. It fills the whole backyard with quality sound. My friend had the Onyx Studio 1 without the Aux input but I like this one much better since it has a 3.5mm jack so that saves on some battery and the sound quality is better. Best Bluetooth speaker on the market.

Rated 1 out of 5 by from I love the product but... I love the onyx studio speaker, I love it so much that when a friend broke my first one, I bought a refurbished one to replace it, even tho it cost me twice as much as I payed in the first place. I was really excited to recieve my new speaker in the mail, but when it arrived the Bluetooth was messed up and wouldn't connect to any of my devices, so I returned it through the mail but have yet to recieve a tracking number or notice that it was recieved, and that was 2 weeks ago! I'm very disappointed with the lack of communication and failure to deliver in a timely manner, not to mention that they're selling refurbished old speakers for twice as much as they were through amazon less than 6 months ago.

Can i plug in the Onyx Studio 2 adapter and keep listen to music all the time? Is it harmful?

Asked by: Keanyiap
It's actually not harmful. Our portable speakers were originally designed and tested to be used plugged in, it will produce a more powerful sound. Aside from that, the reason why it isn't harmful is because of the adapter. Once the speaker is fully charged and is still plugged in, it will run on electricity, not from the battery. The adapter prevents the speaker from taking more electricity than it should.

How to connect two onyx studio 2 to my phone via bluetooth? Thanks

Asked by: JohnT
If you mean connecting both speakers to play a the same time then unfortunately that won't be possible. You can pair both of them on the phone but can only connect one at a time.

I have Dolby audio equalizer in the music app of my phone that raises the volume level way higher than normal. Now my question is will raising the volume level to Max cause the speakers to blow or crack due to higher sound pressure than usual

Asked by: D1bound
Our portable speakers have a ceiling limit of 0db. Now if you use the equalizer to raise the volume higher than normal, then yes, there is a possibility of blowing up the speakers.
