    I bought this speaker with a gift card I got from family for general use with doing chores around the house, and helping concentrate on homework with some music in the background. I recommend this speaker to everyone it’s great quality with Bluetooth technology as well and is very loud if you want it to be!

    Everything about the Onyx Mini was just perfect - the sound, the size, the bass, the build and the connectivity. Except the lack of portability (it doesn't fit in my pocket & harman kardon hasn't provided any carrying case), there's nothing to complain about this small wonder. Get this below $99 and you'll never regret

    Love the sound of it! Good quality and surprisingly great bass for a small stereo. BT works great. You can talk and listen to your phone calls through the speaker which is a great feature! I got mine for 50$ which was well worth it!

    Absolutely love this gem of a speaker. Love it so much I've bought two for myself, you can pair two from one iPhone, and one for my daughter. I've also bought a form fitting hard case designed specifically for this speaker to take on the go. I tried several speakers including the small Bose and the Mini absolutely has the best sound. clear highs and full mids with good bass. I also own the large Onyx and the mini almost sounds as good as the big brother without the booming bass. The Mini will definitely fill a room with great sound. You will be amazed! I was.

    Harman/Kardon quality in Bluetooth speaker

    This was my first Bluetooth speaker purchase so I didn't know what to expect. I am impressed with sound, looks, and quality of build, plus I caught it on sale. I always heard that Harman/Kardon was high end and this speaker is. Sounds clear and has just enough bass. I listen to hip hop, blues, and gospel and they all sound terrific playing through my speaker. Would definitely recommend.

    I really love my new Harman/kardon onyx mini portable wireless speaker. The sound quality is really amazing it most definitely gets the job done for me. I really like the fact that it holds a charge for a very long period of time. I purchased several of these Harman/kardon for gifts during the holiday.

    The sound quality is amazing for its size. Does take eight hours to charge for the first charge out of the box, but for about 10 hours of playtime it is worth it. Like that it has a power indicator on the top so you know if you are about out of battery power.

    As long as it packs a loud and powerful punch, I'd recommend it to anyone. This speaker (for the size it is) packs a wallop. Has a decent battery life also but is best if plugged up for continuous playback.

    After my brother in law raved about this speaker so much I thought I'd give it a try. I was so impressed by the clarity and quality of such a little speaker. It is very loud too!

    Great Bluetooth speaker, built sturdy and very easy to use, puts out big music sound. Connectivity up to 3 Bluetooth devices and Dual play.This HK Onyx mini exceeded all my expectations. . In keeping with Harman Kardon sound this bluetooth speaker is very clean and crisp in the sound it emits and can get quite loud in relation to its size. The bass is tight and not boomy with the nice separation of the lows where bass guitar notes are clear as well as the bass drum in music. The bass is definitely there and can be felt, but not overpowering . Easy to carry around and can fill up a room easily .

    Portable, elegant, with great sound, very good bass. Connects easily to my cell phone via Bluetooth, in no time. When unplugged from the power cord, the battery lasts 10 hours but charges in only 3 hours. 10 hours?, enough for a trip, a party, a picnic. Highly recommended.

    Excellent for the price (under 100) and in that regard it is the best speaker in the category. However if you want crisp highs and enjoy mids you will find the speaker lacking. The Bass is excellent however it often overpowers the mids and highs. Also, the speaker only shines at volumes greater than 50%. Pros: Great for the price Excellent Battery Life AUX connectivity Beautiful Bass All in all if you want a decent BT speaker that is under 100; I would definitely recommend this speaker. But I would want you make an informed decision based on its limitations.

    This is one of the best speakers I owned and it’s even better because it is very portable due to its smaller size. The connection is great it always reconnects when I use it. The speaker has a mini subwoofer on the back which gives it a good bass sound I love it.
