    This is a good speaker for indoor and outdoor use. This can be used from far distances if your Bluetooth device is far away from the speaker itself. It's very compact and can be very useful in different situations like hearing your GPS and etc:

    Researched a few speakers before picking this one up. Narrowed it down to the offerings of Harmon/JBL. Played around with a few in store. Preferred the heavier bass of the charge 3 , but the sale price on this made it a no brainer. Well built speaker with great sound . Can even be synced with another for stereo sound. Only giving 4 stars because the MSRP is outrageous, luckily it's on sale regularly.

    We have a larger version of his speaker in our home and it's awesome. Got the smaller version for my son who was always putting the larger one in his room. He loves this! He even uses it in his car. Super hi quality sound and very portable.

    Went to Best Buy looking for mini speaker. Was listening to Sony and Bose then noticed the Harmon Kardon mini. I already have the Harmon Kardon Omni and decided to buy this one. Very impressive. The compact designs and sounds so nice.

    Honestly, this is hands down the best little Bluetooth speaker you can purchase, specially if you buy it while it's on sale. Compared to the Bose Sound link mini or JBL, this sounds much better & louder. Definitely a "Best Buy" for me.

    Went to the store to buy a Bose bluetooth; store representative recommended this product instead; I was presently supprised with the results when I compared the two and Onyx was less than half the cost; great deal $37 each; bought two

    The sound quality is impressive, as is the battery life. I bought two (one for each iPad) but spend more time having them in the "dual sound" mode and driving from one device. Great sound for upstairs and downstairs at the same time.

    Got this pretty cheap on Black Friday. I didn't test one in store, and by the price, I thought I give it a try. To my surprise, the sounds coming from this little speaker exceeds what I paid for it. For the size, there's decent bass.

    I was stuck between the Bose Soundlink and the Onyx. I chose the Onyx and I am quite impressed. The sound quality is exceptional. The product is well built and is definitely worth the money if you find it cheaper than a competitor.

    First speaker I've had that easily pairs with everyone of my devices right away. Flash sale price couldn't be beat (75% off) but a great item even at full price. Fills a room with crisp sound and nice base for a small speaker.

    Good bass for a small speaker, packs a punch for its size. I have used it at work 6 days a week for 10 plus hours daily on full blast & it has not fallen short of the quality sound & function i have expected from HarmanKardon.

    This is the beginning of linked Bluetooth devices. The MK Mini and all HK Bluetooth speaker newer than the Omni Studio 3 can be linked together to create expansive sound fields. They are mono speakers with excellent sound quality.

    This speaker sounds great with music. I have it connected to my laptop via Bluetooth. It always connects with no problem. I wish it had a bit more treble when listening to voice audio files. Other than that, I'm enjoying it.
