Better than expected.
So happy with my Speaker. I ordered a refurbished one and got a brand new one. So far so good. Battery life is ok, not amazing. Sound is as impressive as I expected love to have it under my desk while working in the office with low volume. The bass is amazing even at low volume. No issues to connect to iPhone. I downloaded its app and works flawlessly. At first the button combination was a bit confusing but got it all figured out aster a while. The speaker is surprisingly heavy but after you listen to the bass you understand why.

A Truly Astounding Portable Speaker
An astounding speaker. Especially in a set, for true stereo. Sound quality, depth, range, equal to expensive home sound systems. Ok, they are not exactly easily portable. Not that they can't be moved around. The app works very well. They last on a charge in the 7 or 8 hour range, depending upon volume. I've had a set of JLB flip 4's for years, they too are an excellent speaker, but in comparison to these Harmon Kardon's, not in the same league. So, if you truly want what might be the very best in portable speakers, choose these!

Good choice for cost
Great balanced single stand alone speaker, not quite audiophile level. The Harmon Kardon One app provides decent equalizer settings, including their Signature Sound setting which emulates, with many recordings, as if the artist is performing just for you, in a near acoustically perfect room. Crisper than most delivery of mid and treble ranges with ample but not excessive bass range. Battery life appears long between charges.

No diff than any other version
Sounds no different or better than the onyx studio 3 or any other version after. Stop changing the number and make an actual different speaker HK.
