    I have wanted one of these for a few years and finally did it. Absolutely NO REGRETS!!! It have an amazing crisp sound with tons of bass. Suprisingly great volume - it's like having a full sound system in one package. It comes on a stand and has a carrying handle, so we use it all over the place. Seriously, if you are considering one - BUY IT!

    Big things come in small packages. I’m this case humongous things come in a thimble. This speaker has incredible sound quality. It’s range is awesome. I was stunned at how clear and clean music sounds when using the speaker. And even more surprised by how much bass this tiny speaker produces. I received more value than I bargained for. Definitely.

    I snagged this baby during the Black Friday sale. I got it for 150 when it’s normally over 400 I believe which is absolutely amazing. My old roommate had one and I loved it. It was perfect for taking out by the pool or bringing with me when I was cleaning around the house and listening to music. I’m so happy to have my own now.

    Bought quite a handful of these speakers for myself and to give as gifts to my cousins. Love the crystal clear sound and the bass gives so much fullness to every song played. It’s very powerful for its size. Truly worth it! Bought it when it was on sale, value for money!

    When I ordered this speaker I thought it was a smaller one so when it arrived, I was shocked that it was 1 ft high. It’s bigger than my large iPad. The sound however, is incredible. When I watch a movie on my iPad with this speaker, I feel like I am in a movie theater. The bass is incredible and the overall clarity is the best!

    Veeeery good speaker. Nice full low fluffy bass and gets pretty loud for it's size. Wonderfull design too, made people turn their heads everywhere I took it. My only prob with it was it's battery life around 4-5 hours on loud volume isn't enough for me. The other thing was the dual connection via bluetooth to another speaker. Kind of needs you to be in a sweet spot otherwise interference occurs and one lags behind the other. Other than that, best BT speaker for it's price.

    I bought this for my son and he loves it. It does put out some decent sound for it's size. The real kicker is he can unplug it and take it outside and it'll still put out pretty good sound. I really haven't had any complaints from my son about the speaker so I'm pretty happy with the purchase.

    Four of these spread throughout my house once I got a new phone with a better RAM and processor they all connected together seamlessly and fill my entire house with booming sound when people come over they ask me where the subwoofer is because they can't believe the base comes out of these little things

    I was looking for a product that was portable with a great sound. Best Buy had many products to choose from. I already purchased a harman / kardon - Onyx Studio 2 Portable Speaker several years ago and was very happy with the sound quality. I looked at the Studio 4 model and was sold. Great Sound for a great price.

    This speaker is exactly what I needed. It is portable and super loud for a small gathering with friends and family. I take it everywhere that I go and I get so many questions and comments about it; and someone always says they want one after the experience with mine. I should get commission for my sales.

    Great Bluetooth wireless speaker, has deep bass port in the rear of the speaker for full penetrating sound, capable of filling a large banquet hall with music, can also link it to another Harmon Kardon speaker for surround sound

    Awesome speaker for the price. Spoiler alert, this speaker can be very loud. There is a app from Harman, which lets you play with equalizer and adjust settings. There are many other premium brands which are way expensive for the same size as this. Definitely recommend.
