Customer Ratings & Reviews

I bought it as a gift to my daughter and she loved to play her music and listen very well, she takes it everywhere in the house or sometimes leaves it in her room and in the whole house you can listen to the music too, also Easy connect to the phone's Bluetooth signal.

The amount of power this thing has still amazes me to this day. It is unbelievable how clean and loud it can be. I was first using it for the gym with my clients and now I use it everywhere, even at the beach. Definitely recommend it!

Literally just received my speaker. Had bought the 2 for the house a few years ago and loved it so last year bought the 4 for my daughter. Now I had to get one just for myself. I’ve read reviews on pairing issues but I haven’t paired the two yet. Anxious to see how the paring works out.

Referred by my Entire Family. Between 4 of Us we have at least 10 of these at Primary &Vaca Homes. Everyone link up and play Music. Love it. Harmon Cardon is the BEST THERE IS IN SOUND QUALITY. Still have me Floor Speakers by Harmon Cardin from 16yrs Ago and they are still BUMPING!

I'm an audiophile and I like to know I'm getting the best possible sound for my money. After doing a lot of research on everything avail I whittled it down to this or Bose. This one is definitely the way to go and I haven't had a moment of buyer's remorse. Nailed it.

After listening to a friends Onyx speaker, I decided to purchase my own. It's a great sounding speaker & packs a lot of sound, in a small package. I've always used mine plugged up, but there have been complaints about the battery life, but haven't encountered this issue with the ac adapter

This speaker is definitely the best speaker for the money. The feature of connecting multiple units together is nice but it cut out several times, I am not sure why. But, I did not buy this speaker for that feature so it does the job perfectly. Definitely recommend!

No speaker is better then this speaker, I recommended this to anyone and everyone. You wont be disappointed

Good deep bass. Highs are okay, but could be crisper. Battery life is not very long. Maybe 4 hours or so before I put it back on the charger. Not really a portable speaker although I use it in my house primarily or it’s good for me. Bass is excellent. 5 stars for my day to day use.

This Bluetooth speaker is much better than I had anticipated!

The big brother to my Onyx mini is every bit what I was hoping for and have come to expect from the Hk Onyx line of portable Bluetooth devices. It’s a must have for those who love to bring their music with them wherever they go. I can’t recommend this product more enthusiastly!!!

Got this for my roommate since the speakers on her laptop was poor. This thing gets loud and is perfect.

This bad boy is louder than I expected it to be! When plugged in it puts out 60 watts vs 30 when unplugged. The only two things that could use improvement in my opinion is battery life unplugged and certain frequencies when it’s plugged in cause the passive radiator to bottom out quickly after a certain volume. Besides that it is an amazing speaker for the money! Thinking about getting a second one to pair with my charge 3 as a center channel and those two for the full sound!

This speaker has not just room filling sound, but house filling sound. The amount of power is nearly unmatched especially for this price range. While this speaker is portable it is louder when plugged into wall and typically, I just leave it plugged in at all times.

I originally bought this as a present for a friend in Mexico, however when I tested out to heard the sound and features I fell in love with it that decided to get one for myself. The sound it produces its amazing and pleasing to the ear regardless of what music genre you are listening to.

For a Bluetooth speaker it has some great sound not to big not to small but not the most portable and the battery life is lacking compared to others.So it has its pros and cons you just have to decide whats important to you

One of the top wireless speakers out there. Quality sound, easy to connect and a battery that really holds charge well.

I like your product . Your products are very good. I need to purchase more products with your company

No tinny sound, shallowness, or “too much bass” with this Harmon Kardin Onyx Studio 4. WOW! The music sounds great, from rock to rap to jazz to symphonic. And one speaker fills the room. I’ve never found an affordable Bluetooth speaker that rivals the sound quality. Highly recommend!

This is the best chargeable and portable bluetooth speaker that I've experienced. Love it!
