Customer Ratings & Reviews

I think its amazing sounding I would highly recommend this speaker for anyone. I only wish this speakers was water proof so I could keep it outside.

Harmon Kardon sound quality is consistently impressive. I haven't found any sound that hits the highs and lows so well! Especially the punchy bass!

this Harmon Kardon Onyx wireless speaker system. Bluetooth connectivity lets you listen from any compatible device, and the rechargeable battery provides up to 8 hours...

You will be impressed with the quality of this speaker that provides a portable, deep, rich musical experience you don’t just hear, but feel.

Clear sound across the spectrum. well balanced and provides a great amount of bass. I am giving up my Beats Pill + for this amazing speaker. This is a great value product.

Heavy on bass and good sound for the money . It’s heavy so if you want something portable this is definitely not the right speaker for you . The volume doesn’t get very loud but maintain a reasonable quality even at the highest volume.

My wife uses this at work. Volume does not go as high as I thought it would but the sound quality is very clean & clear.

easy to set up and put into use, functional. speaker is packed with a big sound! great for multi-room entertainment, since the speakers can link up together.

This speaker is awesome! Lots of bass and long battery life. I have 2 of them and they connect together to have a true stereo sound

Easy set up, loud, good would quality. No complaints regarding the speaker. The accompanying app is a little lacking but the speaker is great.

Purchased this speaker for listening music off my phone. It is very easy for pairing and sound quality is the best I could find for a Bluetooth speaker.

For the price BestBuy offered this speaker for, it was an unbelievable deal. Great sound and ease of use. Every bit as good of any speaker made and I have several.

Speaker is amazing. Sound quality and battery life are best i have ever had in portable speaker. I did buy it when on sale though.

This has excellent sound - and it is great easy to carry inside or outdoors . Highly recommend this - the best Bluetooth speaker for price and sound around!

This has easily has to be one of the best Bluetooth speakers I have ever heard. The sound truly fills the room and the bass exceeds any expectation I may have had.

I own a previous generation Harman Kardon and really like it. Bought this was to take to our vacation home. It is a quality unit and appears to be more durable than my previous model. However, the highs are not quite as clear as my previous model and I do prefer that model for it's clear, crisp sound.

The sound quality, especially the bass was far beyond expectation. Fills a large room with crisp "stereo" like sound.

This speaker sound is amazing. And the battery life is long too

I love this speaker so easy to use I could hear from anywhere in my house and I’m also thinking of purchasing another one great product great price

This speaker Onyx 4 is good for the cost and sound pretty nice, can't compare to hi-end speaker but it's close to them and get to save $300 at least.
