Customer Ratings & Reviews

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.

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

My husband has several wireless speakers, but this one is by far his favorite. It has great sound quality and is portable from room to room.

I bought this on Black Friday based on the suggestion of a fellow shopper. Glad I took their advice because this thing is loud and has great sound

Love this speaker! Great quality, great battery life (8 hours) great sound. It’s right there with Bose and Sony and a lot better price tag.

This speaker is fantastic!!! Is louder the my other one. Bass is there but not to much. Can keep people from wanting to take it from me.

Sound quality is superb. Easy to setup and easy to use. I would recommend this for anyone, who is looking for a quality home speaker.

Its loud and clear, charges in a reasonable amount of time and has great base. Fills most spaces with plenty of sound.

Even though this speaker is somewhat expensive, it is well worth it. This speaker fills up my room with great sound quality and heavy bass.

I am extremely satisfied with my purchase. It's a great speaker with good base and outstanding volume. Looks nice. I would definitely recommend.

This speaker has better sound than our Bose system. Love it - it's a little expensive so watch for a sale. Excellent sound and super simple to connect.

I purchased this speaker on sale and I couldn't be happier. H/K makes great products and this is one of them. It has great sound and a long battery life.

Just like the description says, this speaker has great sound quality. Portability is a great plus. Easy to pair with your favorite mobile device.

Love this speaker. Was looking for bluetooth speaker and this one was perfect size and the sound quality is great.

These speakers sound amazing! You can even pair multiple speakers together! The battery life is pretty decent too!

Been using Harmon Kardon speakers since the nineties including a HK receiver. Love their products and this portable speaker is no exception. Clear crisp sound makes almost everything sound live especially classical and jazz. Bluetooth pairing was easy to do. Its bigger than I thought it would be but it still fits well on my endtable and isn't too heavy. Have also used it to play movies off my laptop. Works great for that. Would buy again.

This speaker is so awesome, This speaker sounds very loud, easy to work. Everyone that came by my place said that speaker is sounds so good

I purchased this speaker to entertain my guest at events. Great sound, and good quality. This speaker is sturdy, and full functional.

This speaker is awesome. We have two, one for each teenager. The sound that comes out of them is spectacular. Great Bass. Attractive design.

Was excited to see the power of this big beast, but once I turned it up the bass cracked like the speaker had been blown. Bummer~ But now I am going to invest in Bose: A brand I trust. Other than this being defective: It’s a quite large, heavy, odd and confusing design that is big on the bass and small on the mids and trebles. Even at low volumes the bass is... well, a lot. It’s matte surface is perfect for showing evidence of every time you’ve touched the thing with any amount of oil on your hands. I recommend looking at other options if you are looking for a nice dependable Bluetooth speaker.
