## Description

Harman Kardon Onyx Studio 8

Review: Big sound, medium package. - I had a studio 3 (I think) that lasted years despite being left outside more than a few times. The sound quality was great so I was stoked to see this refurb option at such a great price. Amazing sound. I think the bass was better on the older model but the clarity is amazing on this one. Can go very loud also. We mostly used the old one for around the pool in the summer. We haven't had pool weather yet so its basically just been us jamming to test it out but it sounds great indoors. It is a bit hefty. Its portable for sure but you aren't going to want to carry it far. We sat around drinking beers and running a spotify jam for 2-3 hours and battery was still going. May update once I find its limits but if it goes a few hours on battery it meets my needs. The old one was always plugged in because the battery failed within a year but it worked fine on ac voltage for 6-7 years after.
Review: Deep bass on a retro package - Matched up to JBL quality at a nicer look

### ⭐⭐⭐⭐⭐ Very happy with this "Renewed" purchase
*by A***R on December 8, 2023*

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.
