Customer Ratings & Reviews

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

Great sound, good bass. Its portability is great and its battery lasts 8 hours as indicated by the box. I Loved it.

Great bluthooth speaker. Connectiveity strong, deep bass, and accurate sound. Volume is as loud as any speaker I have heard.

This is a great speaker. It has crisp sound and a nice size. The battery life is good too. It plays loud!

I have been a fan of Harman Kardon for a while. this is my third Onyx by far the best in battery life. Sound is always been great the only issue in previous models were battery. its alot better in this one,

This is my second Onyx speaker. It has great sound with rich base that can fill the room. Best of all is the Connect feature these speakers have. Press the Connect button on both speaker and you got yourself a nice stereo sound. I use these pair outside for parties and inside for sweat nice music. Two Bluetooth devices can connect to the speaker to alternate music source. I highly recommend these speakers to my friends.

Lots of bass, and more portable than you might think. Decently long battery life too. Good punch for the price

I love my speaker and the sound is great. Battery life, 8 hrs WOW.

Great sounding speaker. Nice sounding bass for a compact system.

This Bluetooth speaker has super deep bass sound along with crisp highs. I bought two in order to have stereo sound and it sounds better than my receiver w speakers. Fills the room completely.

Just bought this to play music. The sound that comes out of this is unreal. Bought it on sale for $149, so got a very good deal. We just love it. Like that we can unplug and take it outside.

The Harrman/kardon -Onyx Studio 4 Portable Bluetooth Speaker is awesome! No problems pairing Bluetooth and the sound/bass sounds clear and gives a rich sound. Voice calls also work great.

This little guy is actually a descent size blue tooth portable speaker that certainly packs the sounds for any time or place. This speaker will satisfy your sound needs for sure!

Bought this for Sister in law who delegated to this model only. So went ahead and ordered on-line with super great sale price, but still doubt if it’ll work nice like Bose. Now I’m pleasantly surprised by both the smooth BT connectivity as well as the sound quality. Set up is very quick w/o too much headache then the sound comes out not just loud w/ enough bass but also clear, though the tenor part is a bit not as crispy enough as Bose, but still pretty good. Size is a bit large but easy to carry due to nice ergonomics. Good buy for the price and would think about getting one just for myself.

This is one the best wireless Bluetooth speaker I've ever heard. The sync is easy. Bought four of them. The bass is phenomenal! Clear mids and highs. Well balanced rich music.

Love, love this speaker. Easy set up . Although the directions were not that great. Nice clear sound. Portable for outside listening. Also got it at an amazing price.

The passive bass unit on the back of the speaker is awesome for producing base. It's OK for the performance on human sounds. All the speakers need to play music on a medium volume for about two days to get the better performance. I wrote this after four days of purchasing. This speaker got silicon covered around its edge so it can be a little splash proof. The surface of the cover made from polyester. Mine is black, which is easy to gather some dust on it. The Bluetooth somehow unable to connect to my new mac book. Price is 14x for the cyber mon deal. ONLY worth the deal price.

I have this set up in my room. I love the sound so much I purchased a second one. The portability will make it useful in any room in the house. Rich, deep sound.

I love these speakers! The sound quality and bass will surprise you especially if you like rap music. I love to disturb the peace with this portable speaker.

This is the best sounding portable speakers I have ever heard! The quality of the sound is just amazing. The bass is the best part about these speakers. Not the loudest for its price, and not the most portable speaker you will ever see, but its design sets it apart. No hesitation in giving 5 stars, especially considering the discount they are on ($150 when I got it)!
