## Description

Harman Kardon Onyx Studio 7

Review: You can move it anywhere. - Best peice of equipment that I bought in a long time. For the money it's great.
Review: Way better than JBL or others - Really glad I went with this option instead of spending about the same on a JBL or other popular brand. The sound quality difference is impressive, because of it's dedicated speakers. It sounds about the same or better than the $400+ Bose Portable Smart Speaker or Sonos Move. I tried them out to compare and it's the best in my opinion. Can't even compare this to JBL or the numerous other bluetooth speakers, even their high end models, this thing is way better. At the price point this is at right now, it is less than half the cost of what it's worth. It can be a bit confusing, with there being an Onyx 6, Onyx 4, etc - I just went with the Onyx 7 after researching a bit and I am glad I did. The Onyx 6 is very similar, just a very slight different sound. I think you'd be good with either and can choose more on looks in my opinon. The battery life advertises at 8hr, but surprisingly it has been 10 hours now and it was still working before I turned it off. We had it at about half volume (which is plenty loud) which might be why. It has a dedicated charger which is maybe a negative, but not a big deal. Great build quality, hefty without being too much to carry around. The packaging and charger quality is pretty impressive, they put some thought and effort into this. Have to give it to Harman Kardon, you aren't just buying a gimmicky name or something with this thing. Sure, it isn't audiophile grade $1000+ speakers, but it's the best speaker in this form factor in my opinion.

### ⭐⭐⭐⭐⭐ Excellent Speaker! Better Than the Onyx Studio 8!
*by J***E on March 21, 2025*

Overall this is a great speaker! The only problem I have with it is after a couple of years the battery dies and needs replacing. The problem with this is that there is no battery with the same exact power ratings available and the battery that is being sold as its replacement is not the same battery. This replacement battery died permanently after a couple of months. It was also prone to shutting the speaker off while playing at maximum volume. The battery also had a shorter lifespan while actively playing at high volume. The original speaker and battery are excellent just don't think doing a battery replacement is going to fix the dead battery issue.
