Customer Ratings & Reviews

So far, so good. It works well for my presentations and for entertainment. Sound is crisp and clear, with little distortion at high volume, but admittedly I didn't give it a thorough test at high volume.

This is my 4th harman kardon speaker, i have been getting them since i first discovered the onyx studio one. Love at first sight, sleep design and awesome bass, you will not be disappointed if you buy it.

I have previously owned HK Onyx Studio 1 and 2. This model, is by far the best one! With the other models, I always had problems with the battery. So far, my battery life has been great! It has a red light that tells you when you need to charge it--something that was not included with the past two models. The design is elegant and slick. The sound is basically same as the other models. If you're a fan of Harman Kardon's Onyx Studio, this is by far the best one they have come up with.

Love the sound. .clear Bass is on point Took a star away due to it not having the cord to connect to devices. Had to buy the cord separately and had to fiddle with it once I had it hooked up. Every now and then I have to check the cord that connects to my PC due to the cord needing proper contact.

Nice speaker very well rounded sound quality, bass, mids, highs.

The speaker sounds great it's a perfect size and it's nice how it's chargeable and you can take it to the beach.

Thus is an excellent sounding speaker. So much power in such a little package. The only downside is the small battery life. I use it around the house, outside working in the garden, etc. Somewhere I know I can plug in, if necessary. It would be nice if it had a battery level indicator: some way to know its remaining charge. But even without these things, the speaker is great. I would recommend it to a friend, and I would buy it again if the need arises.

Over the holidays, Best Buy had this for an amazing price. I went in to my local store to listen to it, but they did not have one set up. While traveling on business the next couple of days, I was able to stop in another Best Buy one evening and check it out. At full MSRP, I would have been hard pressed to purchase, but at the sale price I actually bought one for myself and one for my son. Great sound, size, and performance. Highly recommend if its in your budget.

I know it's pricey but u will love it once u hear the quality and volume and bass u will forget the price tag

These speakers are awesome, with a good bass. The salesman was able to pair one easily with his phone and walked more than 40 feet away before the speakers started to lose the signal. We bought two and paired them together. We often use one on the first floor of our home, and put the other one in the basement, and they work well. We've had them about 6 weeks and have had no issues except for maybe the battery life. We usually keep them plugged in.

I have purchased 2 of the Harmon Kardon speakers in the past! This is my 3rd! I gave 1 away as a Christmas gift and I still have 2. The Studio 3 has to be the best made yet! The leg broke on my first one and it was hard to fix. Since the first speaker, Harmon Kardon has changed the legs and now they are very strudy! The sound is amazing! Lots of BASS!!! Everyone always asks me if I brought my speaker because they love it too! Excellent SOUND!!

Great sounding, portable, long battery life. Love it!

I love this speaker, the sound quality is amazing, even at high volumes. I have it paired to my computer instead of my phone and stream using radio websites all day every day. So far, it hasn't had any interruptions or errors. I don't use the battery that often, but the few times I have it's lasted about the advertised 5 hours. It's very easy to transport and even in large spaces it never sounds poorly. you won't regret it

I was inside a retail store when I was testing this speaker out. The sound was so clear and the bass was amazing. I had to buy it. I purchased this as a Christmas gift on BestBuy.com. I will definitely be buying one for myself! It is easy to connect via Bluetooth for portable listening. Watching movies with the speaker sounds incredible. Charging time is pretty quick and it lasts a while without it needing to be connected.

Compared to my old Bose Sounddock this has a richer, deeper base. Depending on your tastes, maybe too much for a really small room, but great for the patio. (The Onyx Mini also sounds great...more than enough for a bedroom). The battery holds up well, and the BT range seems pretty good even with the microwave running. I was disappointed in my iPhone 5... this speaker uses Bluetooth 4.2 and won't work with older gadgets.

Used this speaker in my barn for a charity function. Easy to use...great sound...easy to move around! Love it!!

Read the review on this speaker and thought I'd give it a try. Turned out to be a very good buy. I use this speaker with my phone or computer. Music sounds great. Very crisp and clean. I am now waiting for a sale so that I can pick up a second speaker. Well worth the wait.

Very loud. Easy connection. Great size. My sister brought two after she heard my speaker.

Very nice speaker, Put it in the new remodel kitchen on the counter. You can hear it but you can’t see it, I keep hearing where’s the sound coming from, really nice.

Excellent sound, easy to connect Bluetooth, wireless not heavy to take carry, portable
