As always, an excellent performance from Harman/Kardon, he already has us accustomed to his sophisticated sound, bass that impact, some media that are enjoyed and treble that are exciting,, in general a warm and well-defined sound, without any distortion and an excellent volume level. It's a good product.

I have purchased the onyx 3 , 5 and 6. Overall love this one the best. Great sound and base. If what you want is the best sound experience and quality for your dollar, this is amongst the best. Loving it . The sound experience is unique, clean voices , outstanding base and the horns excel. Over all you can't get better

[Employee of bestbuy] I bought this as a way to keep me going throughout the day with the sounds of music, but I connected it to my TV and I was blown away! The enhanced bass and highs gives a theatrical experience to sitcoms and cartoons. Though the speaker itself can have some overwhelming high bass, some EQ’ing can treat it right (speaker itself does not have an equalizer AFAIK). Battery life on this thing exceeded my expectations. Going on 10 hours so far on it and the battery hasn’t gotten low. Definitely my money’s worth! P.S. the handle doesn’t swivel, it’s stationary.

[Employee of bestbuy] JBL and Harman Kardon are subsidiaries of the parent company Harman. That being said although they are different companies, both JBL & Harman Kardon coincide collectively under Harman. For starters, as cool as it would be the stand is stationary and does not swivel. The vocals, base, and equalizer produce sounds like no other. 10+ hours of battery life off charger. Perfect for a birthday or Christmas wishlists satisfaction guaranteed.

I love this speaker! It produces amazing sound, charges well. Can't go wrong with a harman. Ive always been a fan of their speaker. This is my 2nd one! Even bought one for my mom and she loves it. So in all, ive purchased 3 speakers. Satisfied customer.
