This is really a high quality speaker with great room filling sound. Because of its size and look, it can be placed in a room and not even noticed as a speaker. Bass is good and does not distort at higher volumes. Connected quickly to my iPhone. Very pleased with this purchase and the sound the speaker provides.

Great speaker for college student moving into a dorm, doesn't take a lot of space but has great sound. Also a nice feature is that you can connect two of them for a larger space or home. We recently used it on a pontoon boat we rented, had a party in the middle of the lake. Harman/kardon = great quality.

I have the larger HK Onyx 2 but I had been wanting a smaller bluetooth speaker that was more portable. This came up on one of the Best Buy flash sales for $50 so I jumped on it, based only on how much I like my big Onyx 2. I'm not disappointed. For the size (about the size of a softball) it sounds great. I've heard other small bluetooth speakers and to me the sound from this is much better. And the battery life so far is great. I recommend it if you're looking for a small portable speaker.

Love this little speaker. It's crisp clear and loud . Returned two other speakers and got this one . You won't be disappointed. Wait until it's on sale $199 is a bit much for this one but you can't beat the sound quality for its size ! Half the size of others and sounds better and great bass !

This thing is so cute!. The sound is AWESOME! The quick connect is extremely handy. I love the fact that it can be used wireless. I have SO MANY speakers in my house at the moment, I took this back to the store - but, I miss it EVERYDAY for all of it's features. I had this in my bathroom and it was like having a concert in there. I regret that I took it back. If I get it again, I might get 2 just to use it's Dual Stereo feature...

I have the full size HK Onyx (older model). The mini has just as good quality sound as the full size HK Onyx has, plus it has the speaker phone feature! It is light weight, small (but not too small), and excellent sound quality. I recommend it to everyone, especially since its so portable!

I had no intention of purchasing a speaker when i made this particular trip to best buy.. i walk around occasionally to burn time! Anyways, i just so happened to turn down the bluetooth speaker aisle and looked down and it said $49.99 "save $150" i JUMPED on it!! Being an HK i was absolutely stoked! I bought the 2 year coverage for 10 dollars. I got home and the packaging was flawless and its exactly what you would expect being a luxury speaker. It had no problem connecting to my phone. You can charge it using any old android charger, it also connects via AUX. it was so loud the bass hits much harder than you would expect. If you listen to hip hop or dubstep its for you.. its great for metal too! It has a sub on the back side so it CAN be difficult to carry because of the sub but it has a nice sleek, and solid design.. doesnt wobble. I set mine on the floor below me when i game for amaaaaaazing quality listening. Buy this speaker.

I bought this speaker because it was discounted $150. I thought it was deeply discounted because the quality was poor, but I was wrong. The quality is superb. It's exactly what I needed for the space I live in. The bluetooth connects quickly, and I love its portability.

Excellent sound quality and volume. Love bluetooth capabilities for use with my conference calls as well. We are actually using it as a monitor inside our pulpit for soundtrack feedback at church. Could not have gotten a better speaker. Battery life is remarkable.

Bought this during a flash sale - and very pleased I did. The bluetooth works seamlessly with my iPhone. Sound quality is good, base is strong. The rechargeable battery goes for hours. I carry it everywhere - I just wish I could find a protective case.

I went in to my local Best Buy to look at portable Bluetooth speakers. I already own a Bose Mini Soundlink but was looking for something cheaper to take to work with me that wouldn't concern me if it was stolen. The Harmon Kardons were on sale and the sales girl recommended them to me as unbeatable for their current price. While I was looking at the package several more employees recommended them to me and mentioning that they owned one and loved it blah blah. I decided to take the plunge and purchase the last one they had at the sale price and I am glad that I did!! It is an incredible speaker considering I spent about $50.00 for it as it was on sale! However, I would say that if I was spending full price for something, I think I prefer my Bose Mini Soundlink. However my brother thought this little Harmon Karden sounded better! So probably just personal preference

I was looking for a compact and stylish speaker to pair with my Echo Dot. I'm pleasantly surprised with how good this speaker sounds even on high volume. Granted, not the most powerful speaker but excellent for the size. Ended up buying two of them.

This speaker is well made and sounds very good, much better than expected. I chose this one based on cost over the bose soundlink 2. The battery life is so far better than I expected and I would recommend this product.
The only feature I would wish for in addition is the dock charger of the bose model, for coveinience more than anything else. The Bluetooth connection has a good range and works very well

This mini speaker is great! I saw it online for $99 and ordered it, but when I got to the store for pick up, it was actually $49. Not only did I get a credit, but I received a great product. It's small, loud and has a really long battery life.

Awesome little Bluetooth speaker I use it on my desk to play music when playing video games sounds great in a compact size that does not take up too much space. Battery life is good average of 10 hours and can be used with aux cable as well.
