Customer Ratings & Reviews

I was surprised to hear such clarity in the tones of my music. Rich deep bass and clear voices. This speaker really fills the room with great acoustics. I especially like the sound outside by the pool.

Excellent price for a speaker that really delivers. This Bluetooth speaker is easy to use and setup. Sounds awesome. Harmon Kardon is a great company with excellent products

I bought this speaker a few days before black Friday for $139. I got it for my mom who is not at all tech savvy. She loves how clear and crisp it sounds and also how easy it is to connect.

Quality looks with terrific sound. Filling the room with non distorted music at all volumes. Easily connected via bluetooth to my home devices. Best Buy's great price and fast shipping.

This speaker connects easily to Bluetooth. It needs to be plugged in to charge but can then be disconnected from power and moved from room to room. Sound is clear - good, crisp bass. Great purchase!

Love this thing, great sound and battery life. I also like the fact you can link two (or several) together for stereo sound or like across the back patio. Will be buying more!

Bought this speaker for my wife and we love it! The clarity is amazing, no distortion at the higher audio levels and the bass kicks hard! Highly recommend this speaker for the price.

This is one of the larger blu-tooth speakers Ive seen and used. Its got great bass and full range of tones come out of this speaker with ease. Made well. Not water resistant and to be portable I suggest keeping the box it comes in as a good carry case. Has phone answering ability and can connect with other onyx speakers. Great buy on sale for 145.00

This speaker is amazing! The sound is better than the Bose wave radio! The battery life is awesome and it was very easy to sync with my iPhone!

Easy to set up, sounds great, louder than expected.

I bought this because I didn't want to buy a stereo. I wanted something small, light, and portable. This speaker is loud too. I am glad I bought it

Great bass and volume. Connects right away to my phone and Bluetooth tv setup. Mid range isn't real sharp so I use a app to adjust the settings. Very happy with this.

I bought my first HK Onyx speaker 2 years ago and fell in love with it. I bought this second speaker as a gift for my niece since she always wanted to use mine. Unfortunately I have not received the second speaker at the time of this posting but I trust it will be as good or better than the one I have.

I bought a Bose Bluetooth Speaker ($300) and a HK Onyx Studio 2 at the same time and found the HK was the better speaker. Since then I've purchased five of them, one for each of my grown children, who love them. One has a HK Onyx 2, two have the HK Onyx 3, and two have the HK Onyx 4. I am ordering another Onyx 4 today to replace the one I just gave to my daughter. I ordered two Onyx 4s at the same time and one did not have the full sound the others had. I took it to a Best Buy store and my money was refunded. I then ordered another one and it sounded great. I'm very happy with these speakers.

This Bluetooth speaker has excellent audio quality with plenty of power and nice deep bass due to the separate subwoofer on the back of the Bluetooth speaker.

one of the best speakers out there to date. great battery life and even more sound protection when plugged in to the power source. thumping bass and great tweeters for your mids and highs.

loud and crisp works on 10 hr without charging great outside!

This is the best wireless speaker for the money, hands down! Great sound and even better base. Never would have thought the high of quality and volume a device this small could put out!

I love this speaker, is small but with an excellent quality audio better than Bose speaker and for that price is even better. Defenetly I will buy another one.

I love the deep sound and the size; very convenient. My only issue is that it doesn’t seem to hold the 7-8 hours of battery power they tout. Overall a great product tho.
