Review: 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!
Review: Excellent Product... worth for the price.... - The Sound Quality is Excellent Spent 155$ and its worth what I have paid for it. Look and feel is excellent. Bluetooth connectivity is excellent, has AUX too. Super portable... Over all.. Its worth for money....
