Harman Kardon Onyx Studio 8 (Renewed), Black

I purchased my renewed harman kardon onyx 8 for $149. I thought this was a steal since the original price was around $400 but after some late research, I found you can pick up a new one for around $180 - $200.Despite the price drop on brand new, I still saved about $50 and as far as I can tell, this thing is barely used. It appears from the box and all contents inside, someone bought it, tried it out, and either had buyers remorse, or thought it should be better for what they paid.The package arrived in a harman kardon box sealed but you could tell that it had once been opened. Product inside was wrapped in a cover to protect it during shipping, and the cardboard holders that keep the speaker stable, contained instruction book, warranty registration info, and the power cord, all like it was freshly packaged and unused. Had this not said renewed when I bought it, I wouldn't have picked up on any of these slight hints of it being used (instruction book had miniscule bend, black shipping box had white creases suggesting it had once been opened.)For about $150 this speaker is awesome! It blows my Bose sound link from 6 years ago out of the water. Although it is much much bigger, this is the system I've been missing since the days of mini shelf systems with miles of speaker wires and cassette decks and cd changers.I feel the bass is punchy, almost too much. I had to go into my settings for my music service and adjust the equalizer a bit. The sounds are clear, and at only 50% volume, it has room filling sound.It comes with a robust long power cord and it is reported that it will run on battery power for 4 to 6 hours. This will be varied based on listening volume, the higher you play it, the more power it consumes.Whether you choose to buy renewed or purchase a brand new unit, this speaker will not disappoint for most applications.So let me clear the last comment up. This will not work for you if you want something extremely portable. This thing is about as big as a regulation size basketball. So where my Bose sound link could sit in small narrow places, I will have to rethink where I set this. Also, it doesn't appear to be resistant to water (so probably not good close to pool or hot tub - like closer than 5-10ft is probably not a good idea) and the sand from the beach will probably ruin this speaker. Those are my only negatives.

This is the BEST sounding bluetooth speaker. Seriously, i will not buy another speaker ever. When plugged in, it sounds like this thing has a big subwoofer. I can hear it through walls no problem. Its loud, and crisp. Im an audiophile and this thing impressed me big time. Yes, when its not plugged in it looses a bit of its sound. The built in amp lowers its output to save battery. Which, im okay with. It still sounds crisp and clear just not as much bass.

My son ordered this speaker for himself and absolutely loves it. The sound quality is amazing. His friends loved it so much they went and ordered one as well.

High quality, loud for rooms, casual design makes it look like a decoration piece

Pretty decent speaker. Had a onyx studio 7 and it had way more bass than this model. This my only criticism.UPDATE:WORKS EVEN CHEAPER WHEN UNPLUGGED FROM THE WALL. NO BASS, LOW VOLUME....HARDLY.I really was looking forward to this thing working correctly. Its cheaper sounding than my cheapest speaker.FURTHER UPDATE:AMAZON AND THE SELLER WEREN'T TRUTHFUL. I was told that there would not be a charge for returning this item yet I was.I have receipts of proof.

Replacing my onxy 3 with the 8, so much clearer, bass is powerful, and the audio is excellent. Sound fills the room! 10/10, if you don’t like it return it I guess but I’m super happy. The refub shop did a great job, not a scratch on it.I use it to sync up with my peloton audio, works great for it! Super stoked!

Great speaker

Great quality I’m satisfied
