I have many wifi speakers, including the Bose III.
But for the ease of transport and quality of sound, including awesome base, the Harmon/Kardon is the way to go. It provides the most fun and satisfaction for the price. I take it everywhere!

This speaker delivers stereo sound and decent bass for its size. Vocals are clear, highs are crisp and bass is not distorted. Battery life is very good, I have two and pair them together for party mode, Love it!!!

This speaker has LOTS of bass, gets Loud and Low with ease. What i like the best is the reliably easy bluetooth connectivity. This was a great purchase, considering I have two other types of speakers that pale in comparison!

This speaker is amazing! It's small, but delivers huge, clear sound. I love this speaker. The battery lasts forever too. If you're looking for a speaker with powerful sound that lasts more than five hours pick this one.

This is a great speaker for the size. We have this one and the larger size and I can say they both have the same quality output. The larger size puts out more volume but this speaker does great for one room or office.

My first speaker to have at home to do chores or for when I have guests over for gatherings & it works perfect for those type of events. For being a mini, it is pretty loud and clear. & I was fortunate to get it on sale so it was a win-win situation for me. I have definitely have gotten my moneys worth with this purchase.

I love this little guy. It is loud enough to fill up almost the whole house. Clean and clear lows and highs. All that plus a 10 hour battery life. Hands down best portable Bluetooth speaker I've come across.

Great wireless speakers. I bought two, so I could link them with my Amazon Dot. Great purchase. The bass is deep and the sound is great. Great value for the prices. Easy to use and no negatives yet.

Got it for real cheap (less than $70) before my rewards credit and it's well worth it. The sound is much better than Bose color which cost me more than this. I wanted something compact to take to work without sacrificing the sound. I used to take the Bose color but discovered something missing when playing certain music and started looking for replacement, then this came out. I have the bigger version and very pleased with it but a little too big to take to work and I'm very happy they came out with a smaller version. The only thing is a little awkward to carry. I wish they had put a slot for a handle like the big one. Other than that it's great. Not worth losing a star over it.

This mini speaker sounds great. Bought several as gifts and everyone loves them. Battery life is long, and the small size makes it easy to carry with you. Watch for sales on this speaker.

Overall a well rounded Bluetooth speaker. Under $100 right now! Works unbelievably well. Battery lasts for 10 hours. Better than my bose blue tooth speakers. Much more crisp and smooth. Really fun to watch the subwoofer move on the back of the speaker. Worth way more than offered price. Feels like a steal.

If you have an Amazon Echo Dot and were looking for a great speaker to pair it with, look no further than the Onyx Mini. I used to have my Dot paired with a JBL Flip 2 but the sound from the Mini is much better.
Given the dimensions of the Mini you won't fill the room with lots of bass but most music is crisp and clear. The Bluetooth works well and it never turns off when paired with the Dot.
I can always count on Alexa to play the music I want and it'll sound great coming out of the Onyx Mini. Right now I have it positioned across from the foot of my bed and the sound on the Mini is still quite powerful. You should buy one today!

Love the sound quality. Compared to other portable Bluetooth speakers I own this one has to be one of the loudest. Very nice and compact.

We were looking for a good, affordable, and non-intrusive Bluetooth speaker to use with Echo. It needed to be loud enough for basic music listening during the day and for news updates. So far this speaker has worked out great for that purpose. One of the things I was concerned about was maintaining Bluetooth connectivity basically all the time since we just leave it turned on and sitting on an end table. This has worked great with no lagginess or lost connections.
This isn't the same loudness or quality as a sound system would be but it's much better than the mini Bluetooth speakers and a nice, portable, good sounding unit.
