Customer Ratings & Reviews

I purchase this on special for $150. I own the original Onyx for more than year and still sounds great. No problems so far this one has the same sound quality and the feature to answer the phone on the speaker is a little difficult to press the button to activate it.

This is the 5th one that I purchased. The sound is magnificent. My husband, both daughters, and my sister all fell in love with this speaker, so I had to buy extra gifts for Christmas. I still have the original one I purchased last year, and it still sounds like new.

I don't believe I could have made a better purchase anywhere! I just happened to look at your online ad and bang!@#, the Harmon Karden Bluetooth speaker appears!!! I was instantly interested because of the H&K brand repetition. I had to have it!! Sounds incredible!!

Fabulous speaker. It's great for a small space but also works nicely in a large open space. I needed something to attach a keyboard for classroom use and it works perfectly! I haven't tried it with the bluetooth feature yet, but with an auxiliary cable it's great!

Big sound with great clarity. We also own the original Onyx Studio speaker. While both speakers have great overall sound, the Onyx Studio 2 has an improved clarity, as well as a more rugged grill cover mesh. This is an exceptional bluetooth speaker for the price!

The sound quality and volume capabilities are exceptional. However, there is no way to lower the bass on the speaker so that even at low volumes, high quality MP3's will shake the room a bit. Would like a little more user control settings for the speaker itself.

The sound is amazing on this speaker. A friend of mine owns one and I couldn't believe the sound that came from it. Having a aux outlet is nice because I have an older iPod that does not have Bluetooth and I was able to plug it into aux and get a fabulous sound.

Best Buy has the BEST price on this amazing speaker. It has a great base, mids, and highs. It will fill a fairly large room with sound with no problems. Buy without hesitation. It's best use is for the house, but it does have a battery which makes it portable.

First, HK is excellent (comparing to similar class of Bose and JBL). Second, bluetooth connectivity is super-easy. Last, the $149 price is unbeatable. Was only planning to get the Onyx Studio 1 for that price, ended up with a better value for that price!

Very happy to have the speaker add a touch of music to our southern home. Easy to carry to the deck or use power cord to hook up cell or ipod indoors. Big thank you to our salesman who spent the time listening to our needs and suggesting the speaker, .

I bought this during the 2015 Thanks giving sale for a great price $150 compared to $450. Works great with all my devices. The quality of sound is just ultimate. I like the fact that it has in-built battery so the music follows me where ever I go..

Easy to use. Great sound. Travels well. A little awkward size.

I purchased a couple of these as Christmas gifts. It was a little bigger than anticipated but still fits on a computer desk (will be used for gaming as well as music). It delivers incredible sound with rich bass tones! My son absolutely loves it!

I was looking for a great-sounding Bluetooth speaker and was pretty discouraged by all of the shallow/hollow sounding speakers I've tried out. My wife and I just happened to stop at BestBuy to look at printers but ended up with this speaker to compliment the printer. lol I must say I am very impressed with the deep rich sound. I've cranked the volume up to its max and still have no problems with distortion. No matter what the volume is set at this speaker sounds great. I do only have one problem with it which is the onboard battery. It's supposed to last up to 5 hours? Heck, I can't get it to last 5 songs. IOW, it's a fantastic sounding speaker as long as you don't take it away from a wall plug and the only reason it received 4 out of 5 stars.

Harmon Karden absolutely nailed it with this product! I would tell anyone about how great of quality this has in it! Amazing! Go get this Onyx Studio 2

I like the sound, and also the easly to carrie to everywhere.

I purchased this speaker because my brother had one and I loved the sound. I've had similar Bluetooth wireless speakers but loved the sound and clarity so much more. I couldn't pass it up since it was also on sale. Highly recommend this speaker!

This speaker has great full sound for a small portable speaker. It is very easy to setup and control from iPod, or from iPad using Pandora. I can't say enough good things, you actually have hear it in person to realize how good it really sounds.

Onyx 2.0 sounds great! Inside or out it got bass. I put it in the back of my golf cart when golfing. Thing is killer. Only downside is there is no battery level display but it lasts a round of golf on a full charge...

This is a powerful wireless speaker and has a aux input. The battery will last approximately five hours or two hours if volume is turned up to loud. I highly recommend this speaker for anyone who is seeking a wireless speaker with great sound.
