  • 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! ... show more

  • 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.

  • Excellent Choice
Great sound clarity even at high volume. The older model i had was great, but this is better. It features a steady base for support. Easy to connect to phone, tablet, or computer. Very portable. Battery has a long life, longer than I thought. So far, I am impressed with this speaker.
