Harman Kardon Onyx Studio 4

I bought this just yesterday and my oh my they're amazing. I live in a studio and the sound absolutely fills up my room. I connected it to my tv and it does a great job at adapting to that as well! Highly recommend if you love bass!

Already had an Onyx Studio 4 from before and still working perfectly, but I Got 3 Speakers to sound as a concert. Breaking down each sound the Bass is deep and rich you can feel the punch at high volume without loosing quality bass totally with zero distortion, the high and medium sound frequencies are clear melting perfectly with the deep bass enough for not to reduce absolutely the low bass, Sound on tweeters and low deep bass on Onyx 4 are more sophisticated than the onyx 6 which surprised me because I returned the onyx 6 and got 2 more onyx 4 studio, and I think Harman Kardon can do even better on onyx 4 studio sound and release a better version of it, but for now I'm just satisfied with these onyx 4 studio putting together to work with the app which helps to communicate each other to sound all at the same time, I didn't know that having several onyx 4 studio in my room makes me listen different sounds on the background that I didn't hear before even in the same songs I already know, wow ! It's impressive, so I'm glad that I did return the onyx 6 and got several onyx 4 studio due to an exhausted comparison between both breaking down and listening to them separately with different songs, repeating, listening and repeating again and at the end the Onyx Studio 4 won the battle, maybe Harman Kardon needs to look back on the Passive speakers (on the back of all onyx studio) which really helps to bring more sophisticated sound than the onyx 5 or onyx 6 which doesn't have any passive speaker, but for now if you have a good ear listening music and matters a rich bass and good tweeters, the Onyx Studio 4 at this moment is the best option.

Excellent sound for its size, it was what I wanted...I loved it!

I've bought it 2 weeks ago after listening to my friends Onyx2 and fell in love with it. Previously I've owned some smaller portables (Bose Soundlink2 and other) which didn't provide the clarity of sound or the oomph that this one gives just fine. The only down side I could point out is its portability. Yes, you can move it between rooms or take it out to the garden, but taking it to the park or the beach doesn't seem to be the best idea.

I've got onxy 2 3 4 all sounds the same and looks identical look out for 5 next year it will do the same just a name change and price hype so by earlier model when price will be massively reduced. Also brought two sound sticks 111 one come with Bluetooth acsess and other one only works with RAC jack lead same price so be careful when dealing with online shop but still a great product be careful you don't get stitched up.

Sound is great! After testing a lot of other models I can tell, best sound quality for its category. Two improvements needed, add micro usb or even better usb-c to charge with any charger. And secondly, improve integration with iOS devices to display remaining battery percentage.

Since I received the speaker I havent stopped listening to music. The sound is so clear and the bass is amazing for size of speaker I think. But I find that the quality of sound of the music to begin with must be good to be able to enjoy the speakers full potential. Excellent I love it, take it round the house with me.

I bought this speaker for my teenage son as he loves music & likes to make his own mixes, he was absolutely thrilled! I couldn't believe that it was recertified! Condition is like new! In fact I'm looking at getting a home theater system now!

I bought 2 of these as gifts for my family but know that I tried them out i definitely want some to put throughout the house. Because you can sink them together. I really recommend these.

Ive had it for 4 months and it was amazing untill my passive radiator ripped
